Pod

Pod is a collection of containers that can run on a host. This resource is created by clients and scheduled onto hosts.

PodSpec

PodSpec is a description of a pod.

Containers

  • containers ([]Container), required

    Patch strategy: merge on key name

    Map: unique values on key name will be kept during a merge

    List of containers belonging to the pod. Containers cannot currently be added or removed. There must be at least one container in a Pod. Cannot be updated.

  • initContainers ([]Container)

    Patch strategy: merge on key name

    Map: unique values on key name will be kept during a merge

    List of initialization containers belonging to the pod. Init containers are executed in order prior to containers being started. If any init container fails, the pod is considered to have failed and is handled according to its restartPolicy. The name for an init container or normal container must be unique among all containers. Init containers may not have Lifecycle actions, Readiness probes, Liveness probes, or Startup probes. The resourceRequirements of an init container are taken into account during scheduling by finding the highest request/limit for each resource type, and then using the max of of that value or the sum of the normal containers. Limits are applied to init containers in a similar fashion. Init containers cannot currently be added or removed. Cannot be updated. More info: https://kubernetes.io/docs/concepts/workloads/pods/init-containers/

  • ephemeralContainers ([]EphemeralContainer)

    Patch strategy: merge on key name

    Map: unique values on key name will be kept during a merge

    List of ephemeral containers run in this pod. Ephemeral containers may be run in an existing pod to perform user-initiated actions such as debugging. This list cannot be specified when creating a pod, and it cannot be modified by updating the pod spec. In order to add an ephemeral container to an existing pod, use the pod's ephemeralcontainers subresource.

  • imagePullSecrets ([]LocalObjectReference)

    Patch strategy: merge on key name

    Map: unique values on key name will be kept during a merge

    ImagePullSecrets is an optional list of references to secrets in the same namespace to use for pulling any of the images used by this PodSpec. If specified, these secrets will be passed to individual puller implementations for them to use. More info: https://kubernetes.io/docs/concepts/containers/images#specifying-imagepullsecrets-on-a-pod

  • enableServiceLinks (boolean)

    EnableServiceLinks indicates whether information about services should be injected into pod's environment variables, matching the syntax of Docker links. Optional: Defaults to true.

  • os (PodOS)

    Specifies the OS of the containers in the pod. Some pod and container fields are restricted if this is set.

    If the OS field is set to linux, the following fields must be unset: -securityContext.windowsOptions

    If the OS field is set to windows, following fields must be unset: - spec.hostPID - spec.hostIPC - spec.hostUsers - spec.securityContext.appArmorProfile - spec.securityContext.seLinuxOptions - spec.securityContext.seccompProfile - spec.securityContext.fsGroup - spec.securityContext.fsGroupChangePolicy - spec.securityContext.sysctls - spec.shareProcessNamespace - spec.securityContext.runAsUser - spec.securityContext.runAsGroup - spec.securityContext.supplementalGroups - spec.securityContext.supplementalGroupsPolicy - spec.containers[].securityContext.appArmorProfile - spec.containers[].securityContext.seLinuxOptions - spec.containers[].securityContext.seccompProfile - spec.containers[].securityContext.capabilities - spec.containers[].securityContext.readOnlyRootFilesystem - spec.containers[].securityContext.privileged - spec.containers[].securityContext.allowPrivilegeEscalation - spec.containers[].securityContext.procMount - spec.containers[].securityContext.runAsUser - spec.containers[].securityContext.runAsGroup

    PodOS defines the OS parameters of a pod.

Volumes

Scheduling

  • nodeSelector (map[string]string)

    NodeSelector is a selector which must be true for the pod to fit on a node. Selector which must match a node's labels for the pod to be scheduled on that node. More info: https://kubernetes.io/docs/concepts/configuration/assign-pod-node/

  • nodeName (string)

    NodeName indicates in which node this pod is scheduled. If empty, this pod is a candidate for scheduling by the scheduler defined in schedulerName. Once this field is set, the kubelet for this node becomes responsible for the lifecycle of this pod. This field should not be used to express a desire for the pod to be scheduled on a specific node. https://kubernetes.io/docs/concepts/scheduling-eviction/assign-pod-node/#nodename

  • affinity (Affinity)

    If specified, the pod's scheduling constraints

    Affinity is a group of affinity scheduling rules.

    • affinity.nodeAffinity (NodeAffinity)

      Describes node affinity scheduling rules for the pod.

    • affinity.podAffinity (PodAffinity)

      Describes pod affinity scheduling rules (e.g. co-locate this pod in the same node, zone, etc. as some other pod(s)).

    • affinity.podAntiAffinity (PodAntiAffinity)

      Describes pod anti-affinity scheduling rules (e.g. avoid putting this pod in the same node, zone, etc. as some other pod(s)).

  • tolerations ([]Toleration)

    Atomic: will be replaced during a merge

    If specified, the pod's tolerations.

    The pod this Toleration is attached to tolerates any taint that matches the triple <key,value,effect> using the matching operator .

    • tolerations.key (string)

      Key is the taint key that the toleration applies to. Empty means match all taint keys. If the key is empty, operator must be Exists; this combination means to match all values and all keys.

    • tolerations.operator (string)

      Operator represents a key's relationship to the value. Valid operators are Exists and Equal. Defaults to Equal. Exists is equivalent to wildcard for value, so that a pod can tolerate all taints of a particular category.

    • tolerations.value (string)

      Value is the taint value the toleration matches to. If the operator is Exists, the value should be empty, otherwise just a regular string.

    • tolerations.effect (string)

      Effect indicates the taint effect to match. Empty means match all taint effects. When specified, allowed values are NoSchedule, PreferNoSchedule and NoExecute.

    • tolerations.tolerationSeconds (int64)

      TolerationSeconds represents the period of time the toleration (which must be of effect NoExecute, otherwise this field is ignored) tolerates the taint. By default, it is not set, which means tolerate the taint forever (do not evict). Zero and negative values will be treated as 0 (evict immediately) by the system.

  • schedulerName (string)

    If specified, the pod will be dispatched by specified scheduler. If not specified, the pod will be dispatched by default scheduler.

  • runtimeClassName (string)

    RuntimeClassName refers to a RuntimeClass object in the node.k8s.io group, which should be used to run this pod. If no RuntimeClass resource matches the named class, the pod will not be run. If unset or empty, the "legacy" RuntimeClass will be used, which is an implicit class with an empty definition that uses the default runtime handler. More info: https://git.k8s.io/enhancements/keps/sig-node/585-runtime-class

  • priorityClassName (string)

    If specified, indicates the pod's priority. "system-node-critical" and "system-cluster-critical" are two special keywords which indicate the highest priorities with the former being the highest priority. Any other name must be defined by creating a PriorityClass object with that name. If not specified, the pod priority will be default or zero if there is no default.

  • priority (int32)

    The priority value. Various system components use this field to find the priority of the pod. When Priority Admission Controller is enabled, it prevents users from setting this field. The admission controller populates this field from PriorityClassName. The higher the value, the higher the priority.

  • preemptionPolicy (string)

    PreemptionPolicy is the Policy for preempting pods with lower priority. One of Never, PreemptLowerPriority. Defaults to PreemptLowerPriority if unset.

  • topologySpreadConstraints ([]TopologySpreadConstraint)

    Patch strategy: merge on key topologyKey

    Map: unique values on keys topologyKey, whenUnsatisfiable will be kept during a merge

    TopologySpreadConstraints describes how a group of pods ought to spread across topology domains. Scheduler will schedule pods in a way which abides by the constraints. All topologySpreadConstraints are ANDed.

    TopologySpreadConstraint specifies how to spread matching pods among the given topology.

    • topologySpreadConstraints.maxSkew (int32), required

      MaxSkew describes the degree to which pods may be unevenly distributed. When whenUnsatisfiable=DoNotSchedule, it is the maximum permitted difference between the number of matching pods in the target topology and the global minimum. The global minimum is the minimum number of matching pods in an eligible domain or zero if the number of eligible domains is less than MinDomains. For example, in a 3-zone cluster, MaxSkew is set to 1, and pods with the same labelSelector spread as 2/2/1: In this case, the global minimum is 1. | zone1 | zone2 | zone3 | | P P | P P | P | - if MaxSkew is 1, incoming pod can only be scheduled to zone3 to become 2/2/2; scheduling it onto zone1(zone2) would make the ActualSkew(3-1) on zone1(zone2) violate MaxSkew(1). - if MaxSkew is 2, incoming pod can be scheduled onto any zone. When whenUnsatisfiable=ScheduleAnyway, it is used to give higher precedence to topologies that satisfy it. It's a required field. Default value is 1 and 0 is not allowed.

    • topologySpreadConstraints.topologyKey (string), required

      TopologyKey is the key of node labels. Nodes that have a label with this key and identical values are considered to be in the same topology. We consider each <key, value> as a "bucket", and try to put balanced number of pods into each bucket. We define a domain as a particular instance of a topology. Also, we define an eligible domain as a domain whose nodes meet the requirements of nodeAffinityPolicy and nodeTaintsPolicy. e.g. If TopologyKey is "kubernetes.io/hostname", each Node is a domain of that topology. And, if TopologyKey is "topology.kubernetes.io/zone", each zone is a domain of that topology. It's a required field.

    • topologySpreadConstraints.whenUnsatisfiable (string), required

      WhenUnsatisfiable indicates how to deal with a pod if it doesn't satisfy the spread constraint. - DoNotSchedule (default) tells the scheduler not to schedule it. - ScheduleAnyway tells the scheduler to schedule the pod in any location, but giving higher precedence to topologies that would help reduce the skew. A constraint is considered "Unsatisfiable" for an incoming pod if and only if every possible node assignment for that pod would violate "MaxSkew" on some topology. For example, in a 3-zone cluster, MaxSkew is set to 1, and pods with the same labelSelector spread as 3/1/1: | zone1 | zone2 | zone3 | | P P P | P | P | If WhenUnsatisfiable is set to DoNotSchedule, incoming pod can only be scheduled to zone2(zone3) to become 3/2/1(3/1/2) as ActualSkew(2-1) on zone2(zone3) satisfies MaxSkew(1). In other words, the cluster can still be imbalanced, but scheduler won't make it more imbalanced. It's a required field.

    • topologySpreadConstraints.labelSelector (LabelSelector)

      LabelSelector is used to find matching pods. Pods that match this label selector are counted to determine the number of pods in their corresponding topology domain.

    • topologySpreadConstraints.matchLabelKeys ([]string)

      Atomic: will be replaced during a merge

      MatchLabelKeys is a set of pod label keys to select the pods over which spreading will be calculated. The keys are used to lookup values from the incoming pod labels, those key-value labels are ANDed with labelSelector to select the group of existing pods over which spreading will be calculated for the incoming pod. The same key is forbidden to exist in both MatchLabelKeys and LabelSelector. MatchLabelKeys cannot be set when LabelSelector isn't set. Keys that don't exist in the incoming pod labels will be ignored. A null or empty list means only match against labelSelector.

      This is a beta field and requires the MatchLabelKeysInPodTopologySpread feature gate to be enabled (enabled by default).

    • topologySpreadConstraints.minDomains (int32)

      MinDomains indicates a minimum number of eligible domains. When the number of eligible domains with matching topology keys is less than minDomains, Pod Topology Spread treats "global minimum" as 0, and then the calculation of Skew is performed. And when the number of eligible domains with matching topology keys equals or greater than minDomains, this value has no effect on scheduling. As a result, when the number of eligible domains is less than minDomains, scheduler won't schedule more than maxSkew Pods to those domains. If value is nil, the constraint behaves as if MinDomains is equal to 1. Valid values are integers greater than 0. When value is not nil, WhenUnsatisfiable must be DoNotSchedule.

      For example, in a 3-zone cluster, MaxSkew is set to 2, MinDomains is set to 5 and pods with the same labelSelector spread as 2/2/2: | zone1 | zone2 | zone3 | | P P | P P | P P | The number of domains is less than 5(MinDomains), so "global minimum" is treated as 0. In this situation, new pod with the same labelSelector cannot be scheduled, because computed skew will be 3(3 - 0) if new Pod is scheduled to any of the three zones, it will violate MaxSkew.

    • topologySpreadConstraints.nodeAffinityPolicy (string)

      NodeAffinityPolicy indicates how we will treat Pod's nodeAffinity/nodeSelector when calculating pod topology spread skew. Options are: - Honor: only nodes matching nodeAffinity/nodeSelector are included in the calculations. - Ignore: nodeAffinity/nodeSelector are ignored. All nodes are included in the calculations.

      If this value is nil, the behavior is equivalent to the Honor policy. This is a beta-level feature default enabled by the NodeInclusionPolicyInPodTopologySpread feature flag.

    • topologySpreadConstraints.nodeTaintsPolicy (string)

      NodeTaintsPolicy indicates how we will treat node taints when calculating pod topology spread skew. Options are: - Honor: nodes without taints, along with tainted nodes for which the incoming pod has a toleration, are included. - Ignore: node taints are ignored. All nodes are included.

      If this value is nil, the behavior is equivalent to the Ignore policy. This is a beta-level feature default enabled by the NodeInclusionPolicyInPodTopologySpread feature flag.

  • overhead (map[string]Quantity)

    Overhead represents the resource overhead associated with running a pod for a given RuntimeClass. This field will be autopopulated at admission time by the RuntimeClass admission controller. If the RuntimeClass admission controller is enabled, overhead must not be set in Pod create requests. The RuntimeClass admission controller will reject Pod create requests which have the overhead already set. If RuntimeClass is configured and selected in the PodSpec, Overhead will be set to the value defined in the corresponding RuntimeClass, otherwise it will remain unset and treated as zero. More info: https://git.k8s.io/enhancements/keps/sig-node/688-pod-overhead/README.md

  • terminationGracePeriodSeconds (int64)

    Optional duration in seconds the pod needs to terminate gracefully. May be decreased in delete request. Value must be non-negative integer. The value zero indicates stop immediately via the kill signal (no opportunity to shut down). If this value is nil, the default grace period will be used instead. The grace period is the duration in seconds after the processes running in the pod are sent a termination signal and the time when the processes are forcibly halted with a kill signal. Set this value longer than the expected cleanup time for your process. Defaults to 30 seconds.

  • activeDeadlineSeconds (int64)

    Optional duration in seconds the pod may be active on the node relative to StartTime before the system will actively try to mark it failed and kill associated containers. Value must be a positive integer.

  • readinessGates ([]PodReadinessGate)

    Atomic: will be replaced during a merge

    If specified, all readiness gates will be evaluated for pod readiness. A pod is ready when all its containers are ready AND all conditions specified in the readiness gates have status equal to "True" More info: https://git.k8s.io/enhancements/keps/sig-network/580-pod-readiness-gates

    PodReadinessGate contains the reference to a pod condition

    • readinessGates.conditionType (string), required

      ConditionType refers to a condition in the pod's condition list with matching type.

Hostname and Name resolution

  • hostname (string)

    Specifies the hostname of the Pod If not specified, the pod's hostname will be set to a system-defined value.

  • setHostnameAsFQDN (boolean)

    If true the pod's hostname will be configured as the pod's FQDN, rather than the leaf name (the default). In Linux containers, this means setting the FQDN in the hostname field of the kernel (the nodename field of struct utsname). In Windows containers, this means setting the registry value of hostname for the registry key HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters to FQDN. If a pod does not have FQDN, this has no effect. Default to false.

  • subdomain (string)

      Atomic: will be replaced during a merge

      A list of groups applied to the first process run in each container, in addition to the container's primary GID and fsGroup (if specified). If the SupplementalGroupsPolicy feature is enabled, the supplementalGroupsPolicy field determines whether these are in addition to or instead of any group memberships defined in the container image. If unspecified, no additional groups are added, though group memberships defined in the container image may still be used, depending on the supplementalGroupsPolicy field. Note that this field cannot be set when spec.os.name is windows.

    • securityContext.supplementalGroupsPolicy (string)

      Defines how supplemental groups of the first container processes are calculated. Valid values are "Merge" and "Strict". If not specified, "Merge" is used. (Alpha) Using the field requires the SupplementalGroupsPolicy feature gate to be enabled and the container runtime must implement support for this feature. Note that this field cannot be set when spec.os.name is windows.

    • securityContext.sysctls ([]Sysctl)

      Atomic: will be replaced during a merge

Alpha level

  • hostUsers (boolean)

    Use the host's user namespace. Optional: Default to true. If set to true or not present, the pod will be run in the host user namespace, useful for when the pod needs a feature only available to the host user namespace, such as loading a kernel module with CAP_SYS_MODULE. When set to false, a new userns is created for the pod. Setting false is useful for mitigating container breakout vulnerabilities even allowing users to run their containers as root without actually having root privileges on the host. This field is alpha-level and is only honored by servers that enable the UserNamespacesSupport feature.

  • resourceClaims ([]PodResourceClaim)

    Patch strategies: retainKeys, merge on key name

    Map: unique values on key name will be kept during a merge

    This is an alpha field and requires enabling the DynamicResourceAllocation feature gate.

    This field is immutable.

    *PodResourceClaim references exactly one ResourceClaim, either directly or by naming a ResourceClaimTemplate which is then turned into a ResourceClaim for the pod.

    It adds a name to it that uniquely identifies the ResourceClaim inside the Pod. Containers that need access to the ResourceClaim reference it with this name.*

    • resourceClaims.name (string), required

      Name uniquely identifies this resource claim inside the pod. This must be a DNS_LABEL.

    • resourceClaims.resourceClaimName (string)

      ResourceClaimName is the name of a ResourceClaim object in the same namespace as this pod.

      Exactly one of ResourceClaimName and ResourceClaimTemplateName must be set.

    • resourceClaims.resourceClaimTemplateName (string)

      ResourceClaimTemplateName is the name of a ResourceClaimTemplate object in the same namespace as this pod.

      The template will be used to create a new ResourceClaim, which will be bound to this pod. When this pod is deleted, the ResourceClaim will also be deleted. The pod name and resource name, along with a generated component, will be used to form a unique name for the ResourceClaim, which will be recorded in pod.status.resourceClaimStatuses.

      This field is immutable and no changes will be made to the corresponding ResourceClaim by the control plane after creating the ResourceClaim.

      Exactly one of ResourceClaimName and ResourceClaimTemplateName must be set.

  • schedulingGates ([]PodSchedulingGate)

    Patch strategy: merge on key name

    Map: unique values on key name will be kept during a merge

      Mounted read-only if true, read-write otherwise (false or unspecified). Defaults to false.

    • volumeMounts.recursiveReadOnly (string)

      RecursiveReadOnly specifies whether read-only mounts should be handled recursively.

      If ReadOnly is false, this field has no meaning and must be unspecified.

      If ReadOnly is true, and this field is set to Disabled, the mount is not made recursively read-only. If this field is set to IfPossible, the mount is made recursively read-only, if it is supported by the container runtime. If this field is set to Enabled, the mount is made recursively read-only if it is supported by the container runtime, otherwise the pod will not be started and an error will be generated to indicate the reason.

This cannot be updated. More info: https://kubernetes.io/docs/concepts/workloads/pods/pod-lifecycle#container-probes

  • restartPolicy (string)

    RestartPolicy defines the restart behavior of individual containers in a pod. This field may only be set for init containers, and the only allowed value is "Always". For non-init containers or when this field is not specified, the restart behavior is defined by the Pod's restart policy and the container type. Setting the RestartPolicy as "Always" for the init container will have the following effect: this init container will be continually restarted on exit until all regular containers have terminated. Once all regular containers have completed, all init containers with restartPolicy "Always" will be shut down. This lifecycle differs from normal init containers and is often referred to as a "sidecar" container. Although this init container still starts in the init container sequence, it does not wait for the container to complete before proceeding to the next init container. Instead, the next init container starts immediately after this init container is started, or after any startupProbe has successfully completed.

  • stdinOnce (boolean)

    Whether the container runtime should close the stdin channel after it has been opened by a single attach. When stdin is true the stdin stream will remain open across multiple attach sessions. If stdinOnce is set to true, stdin is opened on container start, is empty until the first client attaches to stdin, and then remains open and accepts data until the client disconnects, at which time stdin is closed and remains closed until the container is restarted. If this flag is false, a container processes that reads from stdin will never receive an EOF. Default is false

  • tty (boolean)

    Whether this container should allocate a TTY for itself, also requires 'stdin' to be true. Default is false.

EphemeralContainer

An EphemeralContainer is a temporary container that you may add to an existing Pod for user-initiated activities such as debugging. Ephemeral containers have no resource or scheduling guarantees, and they will not be restarted when they exit or when a Pod is removed or restarted. The kubelet may evict a Pod if an ephemeral container causes the Pod to exceed its resource allocation.

To add an ephemeral container, use the ephemeralcontainers subresource of an existing Pod. Ephemeral containers may not be removed or restarted.

  • insecureSkipTLSVerifyBackend (in query): boolean

    insecureSkipTLSVerifyBackend indicates that the apiserver should not confirm the validity of the serving certificate of the backend it is connecting to. This will make the HTTPS connection between the apiserver and the backend insecure. This means the apiserver cannot verify the log data it is receiving came from the real kubelet. If the kubelet is configured to verify the apiserver's TLS credentials, it does not mean the connection to the real kubelet is vulnerable to a man in the middle attack (e.g. an attacker could not intercept the actual log data coming from the real kubelet).

    pretty

  • previous (in query): boolean

    Return previous terminated container logs. Defaults to false.

  • sinceSeconds (in query): integer

    A relative time in seconds before the current time from which to show logs. If this value precedes the time a pod was started, only logs since the pod start will be returned. If this value is in the future, no logs will be returned. Only one of sinceSeconds or sinceTime may be specified.

  • tailLines (in query): integer

    If set, the number of lines from the end of the logs to show. If not specified, logs are shown from the creation of the container or sinceSeconds or sinceTime

  • timestamps (in query): boolean

6 - Deployment

Deployment enables declarative updates for Pods and ReplicaSets.

apiVersion: apps/v1

import "k8s.io/api/apps/v1"

Deployment

Deployment enables declarative updates for Pods and ReplicaSets.

DeploymentSpec

DeploymentSpec is the specification of the desired behavior of the Deployment.

  • selector (LabelSelector), required

    Label selector for pods. Existing ReplicaSets whose pods are selected by this will be the ones affected by this deployment. It must match the pod template's labels.

  • template (PodTemplateSpec), required

    Template describes the pods that will be created. The only allowed template.spec.restartPolicy value is "Always".

  • replicas (int32)

    Number of desired pods. This is a pointer to distinguish between explicit zero and not specified. Defaults to 1.

  • minReadySeconds (int32)

    Minimum number of seconds for which a newly created pod should be ready without any of its container crashing, for it to be considered available. Defaults to 0 (pod will be considered available as soon as it is ready)

  • strategy (DeploymentStrategy)

    Patch strategy: retainKeys

    The deployment strategy to use to replace existing pods with new ones.

    DeploymentStrategy describes how to replace existing pods with new ones.

    • strategy.type (string)

      Type of deployment. Can be "Recreate" or "RollingUpdate". Default is RollingUpdate.

    • strategy.rollingUpdate (RollingUpdateDeployment)

      Rolling update config params. Present only if DeploymentStrategyType = RollingUpdate.

      Spec to control the desired behavior of rolling update.

      • strategy.rollingUpdate.maxSurge (IntOrString)

        The maximum number of pods that can be scheduled above the desired number of pods. Value can be an absolute number (ex: 5) or a percentage of desired pods (ex: 10%). This can not be 0 if MaxUnavailable is 0. Absolute number is calculated from percentage by rounding up. Defaults to 25%. Example: when this is set to 30%, the new ReplicaSet can be scaled up immediately when the rolling update starts, such that the total number of old and new pods do not exceed 130% of desired pods. Once old pods have been killed, new ReplicaSet can be scaled up further, ensuring that total number of pods running at any time during the update is at most 130% of desired pods.

        IntOrString is a type that can hold an int32 or a string. When used in JSON or YAML marshalling and unmarshalling, it produces or consumes the inner type. This allows you to have, for example, a JSON field that can accept a name or number.

      • strategy.rollingUpdate.maxUnavailable (IntOrString)

        The maximum number of pods that can be unavailable during the update. Value can be an absolute number (ex: 5) or a percentage of desired pods (ex: 10%). Absolute number is calculated from percentage by rounding down. This can not be 0 if MaxSurge is 0. Defaults to 25%. Example: when this is set to 30%, the old ReplicaSet can be scaled down to 70% of desired pods immediately when the rolling update starts. Once new pods are ready, old ReplicaSet can be scaled down further, followed by scaling up the new ReplicaSet, ensuring that the total number of pods available at all times during the update is at least 70% of desired pods.

        IntOrString is a type that can hold an int32 or a string. When used in JSON or YAML marshalling and unmarshalling, it produces or consumes the inner type. This allows you to have, for example, a JSON field that can accept a name or number.

  • revisionHistoryLimit (int32)

    The number of old ReplicaSets to retain to allow rollback. This is a pointer to distinguish between explicit zero and not specified. Defaults to 10.

  • progressDeadlineSeconds (int32)

    The maximum time in seconds for a deployment to make progress before it is considered to be failed. The deployment controller will continue to process failed deployments and a condition with a ProgressDeadlineExceeded reason will be surfaced in the deployment status. Note that progress will not be estimated during the time a deployment is paused. Defaults to 600s.

  • paused (boolean)

    Indicates that the deployment is paused.

DeploymentStatus

DeploymentStatus is the most recently observed status of the Deployment.

  • replicas (int32)

    Total number of non-terminated pods targeted by this deployment (their labels match the selector).

  • availableReplicas (int32)

    Total number of available pods (ready for at least minReadySeconds) targeted by this deployment.

  • readyReplicas (int32)

    readyReplicas is the number of pods targeted by this Deployment with a Ready Condition.

  • unavailableReplicas (int32)

    Total number of unavailable pods targeted by this deployment. This is the total number of pods that are still required for the deployment to have 100% available capacity. They may either be pods that are running but not yet available or pods that still have not been created.

  • updatedReplicas (int32)

    Total number of non-terminated pods targeted by this deployment that have the desired template spec.

  • collisionCount (int32)

    Count of hash collisions for the Deployment. The Deployment controller uses this field as a collision avoidance mechanism when it needs to create the name for the newest ReplicaSet.

  • conditions ([]DeploymentCondition)

    Patch strategy: merge on key type

    Map: unique values on key type will be kept during a merge

    Represents the latest available observations of a deployment's current state.

7 - StatefulSet

StatefulSet represents a set of pods with consistent identities.

apiVersion: apps/v1

import "k8s.io/api/apps/v1"

StatefulSet

StatefulSet represents a set of pods with consistent identities. Identities are defined as:

  • Network: A single stable DNS and hostname.
  • Storage: As many VolumeClaims as requested.

The StatefulSet guarantees that a given network identity will always map to the same storage identity.

StatefulSetSpec

A StatefulSetSpec is the specification of a StatefulSet.

  • serviceName (string), required

    serviceName is the name of the service that governs this StatefulSet. This service must exist before the StatefulSet, and is responsible for the network identity of the set. Pods get DNS/hostnames that follow the pattern: pod-specific-string.serviceName.default.svc.cluster.local where "pod-specific-string" is managed by the StatefulSet controller.

  • selector (LabelSelector), required

    selector is a label query over pods that should match the replica count. It must match the pod template's labels. More info: https://kubernetes.io/docs/concepts/overview/working-with-objects/labels/#label-selectors

  • template (PodTemplateSpec), required

    template is the object that describes the pod that will be created if insufficient replicas are detected. Each pod stamped out by the StatefulSet will fulfill this Template, but have a unique identity from the rest of the StatefulSet. Each pod will be named with the format <statefulsetname>-<podindex>. For example, a pod in a StatefulSet named "web" with index number "3" would be named "web-3". The only allowed template.spec.restartPolicy value is "Always".

  • replicas (int32)

    replicas is the desired number of replicas of the given Template. These are replicas in the sense that they are instantiations of the same Template, but individual replicas also have a consistent identity. If unspecified, defaults to 1.

  • updateStrategy (StatefulSetUpdateStrategy)

    updateStrategy indicates the StatefulSetUpdateStrategy that will be employed to update Pods in the StatefulSet when a revision is made to Template.

    StatefulSetUpdateStrategy indicates the strategy that the StatefulSet controller will use to perform updates. It includes any additional parameters necessary to perform the update for the indicated strategy.

    • updateStrategy.type (string)

      Type indicates the type of the StatefulSetUpdateStrategy. Default is RollingUpdate.

    • updateStrategy.rollingUpdate (RollingUpdateStatefulSetStrategy)

      RollingUpdate is used to communicate parameters when Type is RollingUpdateStatefulSetStrategyType.

      RollingUpdateStatefulSetStrategy is used to communicate parameter for RollingUpdateStatefulSetStrategyType.

      • updateStrategy.rollingUpdate.maxUnavailable (IntOrString)

        The maximum number of pods that can be unavailable during the update. Value can be an absolute number (ex: 5) or a percentage of desired pods (ex: 10%). Absolute number is calculated from percentage by rounding up. This can not be 0. Defaults to 1. This field is alpha-level and is only honored by servers that enable the MaxUnavailableStatefulSet feature. The field applies to all pods in the range 0 to Replicas-1. That means if there is any unavailable pod in the range 0 to Replicas-1, it will be counted towards MaxUnavailable.

        IntOrString is a type that can hold an int32 or a string. When used in JSON or YAML marshalling and unmarshalling, it produces or consumes the inner type. This allows you to have, for example, a JSON field that can accept a name or number.

      • updateStrategy.rollingUpdate.partition (int32)

        Partition indicates the ordinal at which the StatefulSet should be partitioned for updates. During a rolling update, all pods from ordinal Replicas-1 to Partition are updated. All pods from ordinal Partition-1 to 0 remain untouched. This is helpful in being able to do a canary based deployment. The default value is 0.

  • podManagementPolicy (string)

    podManagementPolicy controls how pods are created during initial scale up, when replacing pods on nodes, or when scaling down. The default policy is OrderedReady, where pods are created in increasing order (pod-0, then pod-1, etc) and the controller will wait until each pod is ready before continuing. When scaling down, the pods are removed in the opposite order. The alternative policy is Parallel which will create pods in parallel to match the desired scale without waiting, and on scale down will delete all pods at once.

  • revisionHistoryLimit (int32)

    revisionHistoryLimit is the maximum number of revisions that will be maintained in the StatefulSet's revision history. The revision history consists of all revisions not represented by a currently applied StatefulSetSpec version. The default value is 10.

  • volumeClaimTemplates ([]PersistentVolumeClaim)

    Atomic: will be replaced during a merge

    volumeClaimTemplates is a list of claims that pods are allowed to reference. The StatefulSet controller is responsible for mapping network identities to claims in a way that maintains the identity of a pod. Every claim in this list must have at least one matching (by name) volumeMount in one container in the template. A claim in this list takes precedence over any volumes in the template, with the same name.

  • minReadySeconds (int32)

    Minimum number of seconds for which a newly created pod should be ready without any of its container crashing for it to be considered available. Defaults to 0 (pod will be considered available as soon as it is ready)

  • persistentVolumeClaimRetentionPolicy (StatefulSetPersistentVolumeClaimRetentionPolicy)

    persistentVolumeClaimRetentionPolicy describes the lifecycle of persistent volume claims created from volumeClaimTemplates. By default, all persistent volume claims are created as needed and retained until manually deleted. This policy allows the lifecycle to be altered, for example by deleting persistent volume claims when their stateful set is deleted, or when their pod is scaled down. This requires the StatefulSetAutoDeletePVC feature gate to be enabled, which is beta.

    StatefulSetPersistentVolumeClaimRetentionPolicy describes the policy used for PVCs created from the StatefulSet VolumeClaimTemplates.

    • persistentVolumeClaimRetentionPolicy.whenDeleted (string)

      WhenDeleted specifies what happens to PVCs created from StatefulSet VolumeClaimTemplates when the StatefulSet is deleted. The default policy of Retain causes PVCs to not be affected by StatefulSet deletion. The Delete policy causes those PVCs to be deleted.

    • persistentVolumeClaimRetentionPolicy.whenScaled (string)

      WhenScaled specifies what happens to PVCs created from StatefulSet VolumeClaimTemplates when the StatefulSet is scaled down. The default policy of Retain causes PVCs to not be affected by a scaledown. The Delete policy causes the associated PVCs for any excess pods above the replica count to be deleted.

  • ordinals (StatefulSetOrdinals)

    ordinals controls the numbering of replica indices in a StatefulSet. The default ordinals behavior assigns a "0" index to the first replica and increments the index by one for each additional replica requested.

    StatefulSetOrdinals describes the policy used for replica ordinal assignment in this StatefulSet.

    • ordinals.start (int32)

      start is the number representing the first replica's index. It may be used to number replicas from an alternate index (eg: 1-indexed) over the default 0-indexed names, or to orchestrate progressive movement of replicas from one StatefulSet to another. If set, replica indices will be in the range: [.spec.ordinals.start, .spec.ordinals.start + .spec.replicas). If unset, defaults to 0. Replica indices will be in the range: [0, .spec.replicas).

StatefulSetStatus

StatefulSetStatus represents the current state of a StatefulSet.

  • replicas (int32), required

    replicas is the number of Pods created by the StatefulSet controller.

  • readyReplicas (int32)

    readyReplicas is the number of pods created for this StatefulSet with a Ready Condition.

  • currentReplicas (int32)

    currentReplicas is the number of Pods created by the StatefulSet controller from the StatefulSet version indicated by currentRevision.

  • updatedReplicas (int32)

    updatedReplicas is the number of Pods created by the StatefulSet controller from the StatefulSet version indicated by updateRevision.

  • availableReplicas (int32)

    Total number of available pods (ready for at least minReadySeconds) targeted by this statefulset.

  • collisionCount (int32)

    collisionCount is the count of hash collisions for the StatefulSet. The StatefulSet controller uses this field as a collision avoidance mechanism when it needs to create the name for the newest ControllerRevision.

  • conditions ([]StatefulSetCondition)

    Patch strategy: merge on key type

    Map: unique values on key type will be kept during a merge

    Represents the latest available observations of a statefulset's current state.

    StatefulSetCondition describes the state of a statefulset at a certain point.

    • conditions.status (string), required

      Status of the condition, one of True, False, Unknown.

    • conditions.type (string), required

      Type of statefulset condition.

    • conditions.lastTransitionTime (Time)

      Last time the condition transitioned from one status to another.

      Time is a wrapper around time.Time which supports correct marshaling to YAML and JSON. Wrappers are provided for many of the factory methods that the time package offers.

    • conditions.message (string)

      A human readable message indicating details about the transition.

    • conditions.reason (string)

      The reason for the condition's last transition.

  • currentRevision (string)

    currentRevision, if not empty, indicates the version of the StatefulSet used to generate Pods in the sequence [0,currentReplicas).

  • updateRevision (string)

    updateRevision, if not empty, indicates the version of the StatefulSet used to generate Pods in the sequence [replicas-updatedReplicas,replicas)

  • observedGeneration (int64)

    observedGeneration is the most recent generation observed for this StatefulSet. It corresponds to the StatefulSet's generation, which is updated on mutation by the API Server.

8 - ControllerRevision

ControllerRevision implements an immutable snapshot of state data.

apiVersion: apps/v1

import "k8s.io/api/apps/v1"

ControllerRevision

ControllerRevision implements an immutable snapshot of state data. Clients are responsible for serializing and deserializing the objects that contain their internal state. Once a ControllerRevision has been successfully created, it can not be updated. The API Server will fail validation of all requests that attempt to mutate the Data field. ControllerRevisions may, however, be deleted. Note that, due to its use by both the DaemonSet and StatefulSet controllers for update and rollback, this object is beta. However, it may be subject to name and representation changes in future releases, and clients should not depend on its stability. It is primarily for internal use by controllers.

    To use this, make a field which has RawExtension as its type in your external, versioned struct, and Object in your internal struct. You also need to register your various plugin types.

    // Internal package:

    type MyAPIObject struct { runtime.TypeMeta json:",inline" MyPlugin runtime.Object json:"myPlugin" }

    type PluginA struct { AOption string json:"aOption" }

    // External package:

    type MyAPIObject struct { runtime.TypeMeta json:",inline" MyPlugin runtime.RawExtension json:"myPlugin" }

    type PluginA struct { AOption string json:"aOption" }

    // On the wire, the JSON will look something like this:

    { "kind":"MyAPIObject", "apiVersion":"v1", "myPlugin": { "kind":"PluginA", "aOption":"foo", }, }

    So what happens? Decode first uses json or yaml to unmarshal the serialized data into your external MyAPIObject. That causes the raw JSON to be stored, but not unpacked. The next step is to copy (using pkg/conversion) into the internal struct. The runtime package's DefaultScheme has conversion functions installed which will unpack the JSON stored in RawExtension, turning it into the correct object type, and storing it in the Object. (TODO: In the case where the object is of an unknown type, a runtime.Unknown object will be created and stored.)*

9 - DaemonSet

DaemonSet represents the configuration of a daemon set.

apiVersion: apps/v1

import "k8s.io/api/apps/v1"

DaemonSet

DaemonSet represents the configuration of a daemon set.

DaemonSetSpec

DaemonSetSpec is the specification of a daemon set.

  • selector (LabelSelector), required

    A label query over pods that are managed by the daemon set. Must match in order to be controlled. It must match the pod template's labels. More info: https://kubernetes.io/docs/concepts/overview/working-with-objects/labels/#label-selectors

  • template (PodTemplateSpec), required

    An object that describes the pod that will be created. The DaemonSet will create exactly one copy of this pod on every node that matches the template's node selector (or on every node if no node selector is specified). The only allowed template.spec.restartPolicy value is "Always". More info: https://kubernetes.io/docs/concepts/workloads/controllers/replicationcontroller#pod-template

  • minReadySeconds (int32)

    The minimum number of seconds for which a newly created DaemonSet pod should be ready without any of its container crashing, for it to be considered available. Defaults to 0 (pod will be considered available as soon as it is ready).

  • updateStrategy (DaemonSetUpdateStrategy)

    An update strategy to replace existing DaemonSet pods with new pods.

    DaemonSetUpdateStrategy is a struct used to control the update strategy for a DaemonSet.

    • updateStrategy.type (string)

      Type of daemon set update. Can be "RollingUpdate" or "OnDelete". Default is RollingUpdate.

    • updateStrategy.rollingUpdate (RollingUpdateDaemonSet)

      Rolling update config params. Present only if type = "RollingUpdate".

      Spec to control the desired behavior of daemon set rolling update.

      • updateStrategy.rollingUpdate.maxSurge (IntOrString)

        The maximum number of nodes with an existing available DaemonSet pod that can have an updated DaemonSet pod during during an update. Value can be an absolute number (ex: 5) or a percentage of desired pods (ex: 10%). This can not be 0 if MaxUnavailable is 0. Absolute number is calculated from percentage by rounding up to a minimum of 1. Default value is 0. Example: when this is set to 30%, at most 30% of the total number of nodes that should be running the daemon pod (i.e. status.desiredNumberScheduled) can have their a new pod created before the old pod is marked as deleted. The update starts by launching new pods on 30% of nodes. Once an updated pod is available (Ready for at least minReadySeconds) the old DaemonSet pod on that node is marked deleted. If the old pod becomes unavailable for any reason (Ready transitions to false, is evicted, or is drained) an updated pod is immediatedly created on that node without considering surge limits. Allowing surge implies the possibility that the resources consumed by the daemonset on any given node can double if the readiness check fails, and so resource intensive daemonsets should take into account that they may cause evictions during disruption.

        IntOrString is a type that can hold an int32 or a string. When used in JSON or YAML marshalling and unmarshalling, it produces or consumes the inner type. This allows you to have, for example, a JSON field that can accept a name or number.

      • updateStrategy.rollingUpdate.maxUnavailable (IntOrString)

        The maximum number of DaemonSet pods that can be unavailable during the update. Value can be an absolute number (ex: 5) or a percentage of total number of DaemonSet pods at the start of the update (ex: 10%). Absolute number is calculated from percentage by rounding up. This cannot be 0 if MaxSurge is 0 Default value is 1. Example: when this is set to 30%, at most 30% of the total number of nodes that should be running the daemon pod (i.e. status.desiredNumberScheduled) can have their pods stopped for an update at any given time. The update starts by stopping at most 30% of those DaemonSet pods and then brings up new DaemonSet pods in their place. Once the new pods are available, it then proceeds onto other DaemonSet pods, thus ensuring that at least 70% of original number of DaemonSet pods are available at all times during the update.

        IntOrString is a type that can hold an int32 or a string. When used in JSON or YAML marshalling and unmarshalling, it produces or consumes the inner type. This allows you to have, for example, a JSON field that can accept a name or number.

  • revisionHistoryLimit (int32)

    The number of old history to retain to allow rollback. This is a pointer to distinguish between explicit zero and not specified. Defaults to 10.

DaemonSetStatus

DaemonSetStatus represents the current status of a daemon set.

  • numberReady (int32), required

    numberReady is the number of nodes that should be running the daemon pod and have one or more of the daemon pod running with a Ready Condition.

  • numberAvailable (int32)

    The number of nodes that should be running the daemon pod and have one or more of the daemon pod running and available (ready for at least spec.minReadySeconds)

  • numberUnavailable (int32)

    The number of nodes that should be running the daemon pod and have none of the daemon pod running and available (ready for at least spec.minReadySeconds)

  • numberMisscheduled (int32), required

    The number of nodes that are running the daemon pod, but are not supposed to run the daemon pod. More info: https://kubernetes.io/docs/concepts/workloads/controllers/daemonset/

  • desiredNumberScheduled (int32), required

    The total number of nodes that should be running the daemon pod (including nodes correctly running the daemon pod). More info: https://kubernetes.io/docs/concepts/workloads/controllers/daemonset/

  • currentNumberScheduled (int32), required

    The number of nodes that are running at least 1 daemon pod and are supposed to run the daemon pod. More info: https://kubernetes.io/docs/concepts/workloads/controllers/daemonset/

  • updatedNumberScheduled (int32)

    The total number of nodes that are running updated daemon pod

  • collisionCount (int32)

    Count of hash collisions for the DaemonSet. The DaemonSet controller uses this field as a collision avoidance mechanism when it needs to create the name for the newest ControllerRevision.

  • conditions ([]DaemonSetCondition)

    Patch strategy: merge on key type

    Map: unique values on key type will be kept during a merge

    Represents the latest available observations of a DaemonSet's current state.

    DaemonSetCondition describes the state of a DaemonSet at a certain point.

    • conditions.status (string), required

      Status of the condition, one of True, False, Unknown.

    • conditions.type (string), required

      Type of DaemonSet condition.

    • conditions.lastTransitionTime (Time)

      Last time the condition transitioned from one status to another.

      Time is a wrapper around time.Time which supports correct marshaling to YAML and JSON. Wrappers are provided for many of the factory methods that the time package offers.

    • conditions.message (string)

      A human readable message indicating details about the transition.

    • conditions.reason (string)

      The reason for the condition's last transition.

  • observedGeneration (int64)

10 - Job

Job represents the configuration of a single job.

apiVersion: batch/v1

import "k8s.io/api/batch/v1"

Job

Job represents the configuration of a single job.

JobSpec

JobSpec describes how the job execution will look like.

Replicas

Lifecycle

  • completions (int32)

    Specifies the desired number of successfully finished pods the job should be run with. Setting to null means that the success of any pod signals the success of all pods, and allows parallelism to have any positive value. Setting to 1 means that parallelism is limited to 1 and the success of that pod signals the success of the job. More info: https://kubernetes.io/docs/concepts/workloads/controllers/jobs-run-to-completion/

  • completionMode (string)

    completionMode specifies how Pod completions are tracked. It can be NonIndexed (default) or Indexed.

    NonIndexed means that the Job is considered complete when there have been .spec.completions successfully completed Pods. Each Pod completion is homologous to each other.

    Indexed means that the Pods of a Job get an associated completion index from 0 to (.spec.completions - 1), available in the annotation batch.kubernetes.io/job-completion-index. The Job is considered complete when there is one successfully completed Pod for each index. When value is Indexed, .spec.completions must be specified and .spec.parallelism must be less than or equal to 10^5. In addition, The Pod name takes the form $(job-name)-$(index)-$(random-string), the Pod hostname takes the form $(job-name)-$(index).

    More completion modes can be added in the future. If the Job controller observes a mode that it doesn't recognize, which is possible during upgrades due to version skew, the controller skips updates for the Job.

  • backoffLimit (int32)

    Specifies the number of retries before marking this job failed. Defaults to 6

  • activeDeadlineSeconds (int64)

    Specifies the duration in seconds relative to the startTime that the job may be continuously active before the system tries to terminate it; value must be positive integer. If a Job is suspended (at creation or through an update), this timer will effectively be stopped and reset when the Job is resumed again.

  • ttlSecondsAfterFinished (int32)

    ttlSecondsAfterFinished limits the lifetime of a Job that has finished execution (either Complete or Failed). If this field is set, ttlSecondsAfterFinished after the Job finishes, it is eligible to be automatically deleted. When the Job is being deleted, its lifecycle guarantees (e.g. finalizers) will be honored. If this field is unset, the Job won't be automatically deleted. If this field is set to zero, the Job becomes eligible to be deleted immediately after it finishes.

  • suspend (boolean)

    suspend specifies whether the Job controller should create Pods or not. If a Job is created with suspend set to true, no Pods are created by the Job controller. If a Job is suspended after creation (i.e. the flag goes from false to true), the Job controller will delete all active Pods associated with this Job. Users must design their workload to gracefully handle this. Suspending a Job will reset the StartTime field of the Job, effectively resetting the ActiveDeadlineSeconds timer too. Defaults to false.

Selector

Beta level

  • podFailurePolicy (PodFailurePolicy)

    Specifies the policy of handling failed pods. In particular, it allows to specify the set of actions and conditions which need to be satisfied to take the associated action. If empty, the default behaviour applies - the counter of failed pods, represented by the jobs's .status.failed field, is incremented and it is checked against the backoffLimit. This field cannot be used in combination with restartPolicy=OnFailure.

    PodFailurePolicy describes how failed pods influence the backoffLimit.

    • podFailurePolicy.rules ([]PodFailurePolicyRule), required

      Atomic: will be replaced during a merge

      A list of pod failure policy rules. The rules are evaluated in order. Once a rule matches a Pod failure, the remaining of the rules are ignored. When no rule matches the Pod failure, the default handling applies - the counter of pod failures is incremented and it is checked against the backoffLimit. At most 20 elements are allowed.

      PodFailurePolicyRule describes how a pod failure is handled when the requirements are met. One of onExitCodes and onPodConditions, but not both, can be used in each rule.

      • podFailurePolicy.rules.action (string), required

        Specifies the action taken on a pod failure when the requirements are satisfied. Possible values are:

        • FailJob: indicates that the pod's job is marked as Failed and all running pods are terminated.
        • FailIndex: indicates that the pod's index is marked as Failed and will not be restarted. This value is beta-level. It can be used when the JobBackoffLimitPerIndex feature gate is enabled (enabled by default).
        • Ignore: indicates that the counter towards the .backoffLimit is not incremented and a replacement pod is created.
        • Count: indicates that the pod is handled in the default way - the counter towards the .backoffLimit is incremented. Additional values are considered to be added in the future. Clients should react to an unknown action by skipping the rule.

      • podFailurePolicy.rules.onExitCodes (PodFailurePolicyOnExitCodesRequirement)

        Represents the requirement on the container exit codes.

        PodFailurePolicyOnExitCodesRequirement describes the requirement for handling a failed pod based on its container exit codes. In particular, it lookups the .state.terminated.exitCode for each app container and init container status, represented by the .status.containerStatuses and .status.initContainerStatuses fields in the Pod status, respectively. Containers completed with success (exit code 0) are excluded from the requirement check.

        • podFailurePolicy.rules.onExitCodes.operator (string), required

          Represents the relationship between the container exit code(s) and the specified values. Containers completed with success (exit code 0) are excluded from the requirement check. Possible values are:

          • In: the requirement is satisfied if at least one container exit code (might be multiple if there are multiple containers not restricted by the 'containerName' field) is in the set of specified values.
          • NotIn: the requirement is satisfied if at least one container exit code (might be multiple if there are multiple containers not restricted by the 'containerName' field) is not in the set of specified values. Additional values are considered to be added in the future. Clients should react to an unknown operator by assuming the requirement is not satisfied.

        • podFailurePolicy.rules.onExitCodes.values ([]int32), required

          Set: unique values will be kept during a merge

          Specifies the set of values. Each returned container exit code (might be multiple in case of multiple containers) is checked against this set of values with respect to the operator. The list of values must be ordered and must not contain duplicates. Value '0' cannot be used for the In operator. At least one element is required. At most 255 elements are allowed.

        • podFailurePolicy.rules.onExitCodes.containerName (string)

          Restricts the check for exit codes to the container with the specified name. When null, the rule applies to all containers. When specified, it should match one the container or initContainer names in the pod template.

      • podFailurePolicy.rules.onPodConditions ([]PodFailurePolicyOnPodConditionsPattern)

        Atomic: will be replaced during a merge

        Represents the requirement on the pod conditions. The requirement is represented as a list of pod condition patterns. The requirement is satisfied if at least one pattern matches an actual pod condition. At most 20 elements are allowed.

        PodFailurePolicyOnPodConditionsPattern describes a pattern for matching an actual pod condition type.

        • podFailurePolicy.rules.onPodConditions.status (string), required

          Specifies the required Pod condition status. To match a pod condition it is required that the specified status equals the pod condition status. Defaults to True.

        • podFailurePolicy.rules.onPodConditions.type (string), required

          Specifies the required Pod condition type. To match a pod condition it is required that specified type equals the pod condition type.

  • successPolicy (SuccessPolicy)

    successPolicy specifies the policy when the Job can be declared as succeeded. If empty, the default behavior applies - the Job is declared as succeeded only when the number of succeeded pods equals to the completions. When the field is specified, it must be immutable and works only for the Indexed Jobs. Once the Job meets the SuccessPolicy, the lingering pods are terminated.

    This field is beta-level. To use this field, you must enable the JobSuccessPolicy feature gate (enabled by default).

    SuccessPolicy describes when a Job can be declared as succeeded based on the success of some indexes.

    • successPolicy.rules ([]SuccessPolicyRule), required

      Atomic: will be replaced during a merge

      rules represents the list of alternative rules for the declaring the Jobs as successful before .status.succeeded >= .spec.completions. Once any of the rules are met, the "SucceededCriteriaMet" condition is added, and the lingering pods are removed. The terminal state for such a Job has the "Complete" condition. Additionally, these rules are evaluated in order; Once the Job meets one of the rules, other rules are ignored. At most 20 elements are allowed.

      SuccessPolicyRule describes rule for declaring a Job as succeeded. Each rule must have at least one of the "succeededIndexes" or "succeededCount" specified.

      • successPolicy.rules.succeededCount (int32)

        succeededCount specifies the minimal required size of the actual set of the succeeded indexes for the Job. When succeededCount is used along with succeededIndexes, the check is constrained only to the set of indexes specified by succeededIndexes. For example, given that succeededIndexes is "1-4", succeededCount is "3", and completed indexes are "1", "3", and "5", the Job isn't declared as succeeded because only "1" and "3" indexes are considered in that rules. When this field is null, this doesn't default to any value and is never evaluated at any time. When specified it needs to be a positive integer.

      • successPolicy.rules.succeededIndexes (string)

        succeededIndexes specifies the set of indexes which need to be contained in the actual set of the succeeded indexes for the Job. The list of indexes must be within 0 to ".spec.completions-1" and must not contain duplicates. At least one element is required. The indexes are represented as intervals separated by commas. The intervals can be a decimal integer or a pair of decimal integers separated by a hyphen. The number are listed in represented by the first and last element of the series, separated by a hyphen. For example, if the completed indexes are 1, 3, 4, 5 and 7, they are represented as "1,3-5,7". When this field is null, this field doesn't default to any value and is never evaluated at any time.

Alpha level

  • backoffLimitPerIndex (int32)

    Specifies the limit for the number of retries within an index before marking this index as failed. When enabled the number of failures per index is kept in the pod's batch.kubernetes.io/job-index-failure-count annotation. It can only be set when Job's completionMode=Indexed, and the Pod's restart policy is Never. The field is immutable. This field is beta-level. It can be used when the JobBackoffLimitPerIndex feature gate is enabled (enabled by default).

  • managedBy (string)

    ManagedBy field indicates the controller that manages a Job. The k8s Job controller reconciles jobs which don't have this field at all or the field value is the reserved string kubernetes.io/job-controller, but skips reconciling Jobs with a custom value for this field. The value must be a valid domain-prefixed path (e.g. acme.io/foo) - all characters before the first "/" must be a valid subdomain as defined by RFC 1123. All characters trailing the first "/" must be valid HTTP Path characters as defined by RFC 3986. The value cannot exceed 63 characters. This field is immutable.

    This field is alpha-level. The job controller accepts setting the field when the feature gate JobManagedBy is enabled (disabled by default).

  • maxFailedIndexes (int32)

    Specifies the maximal number of failed indexes before marking the Job as failed, when backoffLimitPerIndex is set. Once the number of failed indexes exceeds this number the entire Job is marked as Failed and its execution is terminated. When left as null the job continues execution of all of its indexes and is marked with the Complete Job condition. It can only be specified when backoffLimitPerIndex is set. It can be null or up to completions. It is required and must be less than or equal to 10^4 when is completions greater than 10^5. This field is beta-level. It can be used when the JobBackoffLimitPerIndex feature gate is enabled (enabled by default).

  • podReplacementPolicy (string)

    podReplacementPolicy specifies when to create replacement Pods. Possible values are: - TerminatingOrFailed means that we recreate pods when they are terminating (has a metadata.deletionTimestamp) or failed.

    • Failed means to wait until a previously created Pod is fully terminated (has phase Failed or Succeeded) before creating a replacement Pod.

    When using podFailurePolicy, Failed is the the only allowed value. TerminatingOrFailed and Failed are allowed values when podFailurePolicy is not in use. This is an beta field. To use this, enable the JobPodReplacementPolicy feature toggle. This is on by default.

JobStatus

JobStatus represents the current state of a Job.

  • startTime (Time)

    Represents time when the job controller started processing a job. When a Job is created in the suspended state, this field is not set until the first time it is resumed. This field is reset every time a Job is resumed from suspension. It is represented in RFC3339 form and is in UTC.

    Once set, the field can only be removed when the job is suspended. The field cannot be modified while the job is unsuspended or finished.

    Time is a wrapper around time.Time which supports correct marshaling to YAML and JSON. Wrappers are provided for many of the factory methods that the time package offers.

  • completionTime (Time)

    Represents time when the job was completed. It is not guaranteed to be set in happens-before order across separate operations. It is represented in RFC3339 form and is in UTC. The completion time is set when the job finishes successfully, and only then. The value cannot be updated or removed. The value indicates the same or later point in time as the startTime field.

    Time is a wrapper around time.Time which supports correct marshaling to YAML and JSON. Wrappers are provided for many of the factory methods that the time package offers.

  • active (int32)

    The number of pending and running pods which are not terminating (without a deletionTimestamp). The value is zero for finished jobs.

  • failed (int32)

    The number of pods which reached phase Failed. The value increases monotonically.

  • succeeded (int32)

    The number of pods which reached phase Succeeded. The value increases monotonically for a given spec. However, it may decrease in reaction to scale down of elastic indexed jobs.

  • completedIndexes (string)

    completedIndexes holds the completed indexes when .spec.completionMode = "Indexed" in a text format. The indexes are represented as decimal integers separated by commas. The numbers are listed in increasing order. Three or more consecutive numbers are compressed and represented by the first and last element of the series, separated by a hyphen. For example, if the completed indexes are 1, 3, 4, 5 and 7, they are represented as "1,3-5,7".

  • conditions ([]JobCondition)

    Patch strategy: merge on key type

    Atomic: will be replaced during a merge

    The latest available observations of an object's current state. When a Job fails, one of the conditions will have type "Failed" and status true. When a Job is suspended, one of the conditions will have type "Suspended" and status true; when the Job is resumed, the status of this condition will become false. When a Job is completed, one of the conditions will have type "Complete" and status true.

    A job is considered finished when it is in a terminal condition, either "Complete" or "Failed". A Job cannot have both the "Complete" and "Failed" conditions. Additionally, it cannot be in the "Complete" and "FailureTarget" conditions. The "Complete", "Failed" and "FailureTarget" conditions cannot be disabled.

    More info: https://kubernetes.io/docs/concepts/workloads/controllers/jobs-run-to-completion/

    JobCondition describes current state of a job.

    • conditions.status (string), required

      Status of the condition, one of True, False, Unknown.

    • conditions.type (string), required

      Type of job condition, Complete or Failed.

    • conditions.lastProbeTime (Time)

      Last time the condition was checked.

      Time is a wrapper around time.Time which supports correct marshaling to YAML and JSON. Wrappers are provided for many of the factory methods that the time package offers.

    • conditions.lastTransitionTime (Time)

      Last time the condition transit from one status to another.

      Time is a wrapper around time.Time which supports correct marshaling to YAML and JSON. Wrappers are provided for many of the factory methods that the time package offers.

    • conditions.message (string)

      Human readable message indicating details about last transition.

    • conditions.reason (string)

      (brief) reason for the condition's last transition.

  • uncountedTerminatedPods (UncountedTerminatedPods)

    uncountedTerminatedPods holds the UIDs of Pods that have terminated but the job controller hasn't yet accounted for in the status counters.

    The job controller creates pods with a finalizer. When a pod terminates (succeeded or failed), the controller does three steps to account for it in the job status:

    1. Add the pod UID to the arrays in this field. 2. Remove the pod finalizer. 3. Remove the pod UID from the arrays while increasing the corresponding counter.

    Old jobs might not be tracked using this field, in which case the field remains null. The structure is empty for finished jobs.

    UncountedTerminatedPods holds UIDs of Pods that have terminated but haven't been accounted in Job status counters.

    • uncountedTerminatedPods.failed ([]string)

      Set: unique values will be kept during a merge

      failed holds UIDs of failed Pods.

    • uncountedTerminatedPods.succeeded ([]string)

      Set: unique values will be kept during a merge

      succeeded holds UIDs of succeeded Pods.

Beta level

  • ready (int32)

    The number of active pods which have a Ready condition and are not terminating (without a deletionTimestamp).

Alpha level

  • failedIndexes (string)

    FailedIndexes holds the failed indexes when spec.backoffLimitPerIndex is set. The indexes are represented in the text format analogous as for the completedIndexes field, ie. they are kept as decimal integers separated by commas. The numbers are listed in increasing order. Three or more consecutive numbers are compressed and represented by the first and last element of the series, separated by a hyphen. For example, if the failed indexes are 1, 3, 4, 5 and 7, they are represented as "1,3-5,7". The set of failed indexes cannot overlap with the set of completed indexes.

    This field is beta-level. It can be used when the JobBackoffLimitPerIndex feature gate is enabled (enabled by default).

  • terminating (int32)

    The number of pods which are terminating (in phase Pending or Running and have a deletionTimestamp).

    This field is beta-level. The job controller populates the field when the feature gate JobPodReplacementPolicy is enabled (enabled by default).

JobList

JobList is a collection of jobs.

CronJobSpec

CronJobSpec describes how the job execution will look like and when it will actually run.

  • jobTemplate (JobTemplateSpec), required

    Specifies the job that will be created when executing a CronJob.

    JobTemplateSpec describes the data a Job should have when created from a template

  • schedule (string), required

  • timeZone (string)

    The time zone name for the given schedule, see https://en.wikipedia.org/wiki/List_of_tz_database_time_zones. If not specified, this will default to the time zone of the kube-controller-manager process. The set of valid time zone names and the time zone offset is loaded from the system-wide time zone database by the API server during CronJob validation and the controller manager during execution. If no system-wide time zone database can be found a bundled version of the database is used instead. If the time zone name becomes invalid during the lifetime of a CronJob or due to a change in host configuration, the controller will stop creating new new Jobs and will create a system event with the reason UnknownTimeZone. More information can be found in https://kubernetes.io/docs/concepts/workloads/controllers/cron-jobs/#time-zones

  • concurrencyPolicy (string)

13 - HorizontalPodAutoscaler

HorizontalPodAutoscaler is the configuration for a horizontal pod autoscaler, which automatically manages the replica count of any resource implementing the scale subresource based on the metrics specified.

apiVersion: autoscaling/v2

import "k8s.io/api/autoscaling/v2"

HorizontalPodAutoscaler

HorizontalPodAutoscaler is the configuration for a horizontal pod autoscaler, which automatically manages the replica count of any resource implementing the scale subresource based on the metrics specified.

HorizontalPodAutoscalerSpec

HorizontalPodAutoscalerSpec describes the desired functionality of the HorizontalPodAutoscaler.

  • maxReplicas (int32), required

    maxReplicas is the upper limit for the number of replicas to which the autoscaler can scale up. It cannot be less that minReplicas.

  • scaleTargetRef (CrossVersionObjectReference), required

    scaleTargetRef points to the target resource to scale, and is used to the pods for which metrics should be collected, as well as to actually change the replica count.

    CrossVersionObjectReference contains enough information to let you identify the referred resource.

  • minReplicas (int32)

    minReplicas is the lower limit for the number of replicas to which the autoscaler can scale down. It defaults to 1 pod. minReplicas is allowed to be 0 if the alpha feature gate HPAScaleToZero is enabled and at least one Object or External metric is configured. Scaling is active as long as at least one metric value is available.

  • behavior (HorizontalPodAutoscalerBehavior)

    behavior configures the scaling behavior of the target in both Up and Down directions (scaleUp and scaleDown fields respectively). If not set, the default HPAScalingRules for scale up and scale down are used.

    HorizontalPodAutoscalerBehavior configures the scaling behavior of the target in both Up and Down directions (scaleUp and scaleDown fields respectively).

    • behavior.scaleDown (HPAScalingRules)

      scaleDown is scaling policy for scaling Down. If not set, the default value is to allow to scale down to minReplicas pods, with a 300 second stabilization window (i.e., the highest recommendation for the last 300sec is used).

      HPAScalingRules configures the scaling behavior for one direction. These Rules are applied after calculating DesiredReplicas from metrics for the HPA. They can limit the scaling velocity by specifying scaling policies. They can prevent flapping by specifying the stabilization window, so that the number of replicas is not set instantly, instead, the safest value from the stabilization window is chosen.

      • behavior.scaleDown.policies ([]HPAScalingPolicy)

        Atomic: will be replaced during a merge

        policies is a list of potential scaling polices which can be used during scaling. At least one policy must be specified, otherwise the HPAScalingRules will be discarded as invalid

        HPAScalingPolicy is a single policy which must hold true for a specified past interval.

        • behavior.scaleDown.policies.type (string), required

          type is used to specify the scaling policy.

        • behavior.scaleDown.policies.value (int32), required

          value contains the amount of change which is permitted by the policy. It must be greater than zero

        • behavior.scaleDown.policies.periodSeconds (int32), required

          periodSeconds specifies the window of time for which the policy should hold true. PeriodSeconds must be greater than zero and less than or equal to 1800 (30 min).

      • behavior.scaleDown.selectPolicy (string)

        selectPolicy is used to specify which policy should be used. If not set, the default value Max is used.

      • behavior.scaleDown.stabilizationWindowSeconds (int32)

        stabilizationWindowSeconds is the number of seconds for which past recommendations should be considered while scaling up or scaling down. StabilizationWindowSeconds must be greater than or equal to zero and less than or equal to 3600 (one hour). If not set, use the default values: - For scale up: 0 (i.e. no stabilization is done). - For scale down: 300 (i.e. the stabilization window is 300 seconds long).

    • behavior.scaleUp (HPAScalingRules)

      scaleUp is scaling policy for scaling Up. If not set, the default value is the higher of:

      • increase no more than 4 pods per 60 seconds
      • double the number of pods per 60 seconds No stabilization is used.

      HPAScalingRules configures the scaling behavior for one direction. These Rules are applied after calculating DesiredReplicas from metrics for the HPA. They can limit the scaling velocity by specifying scaling policies. They can prevent flapping by specifying the stabilization window, so that the number of replicas is not set instantly, instead, the safest value from the stabilization window is chosen.

        • behavior.scaleUp.policies.type (string), required

          type is used to specify the scaling policy.

        • behavior.scaleUp.policies.value (int32), required

          value contains the amount of change which is permitted by the policy. It must be greater than zero

        • behavior.scaleUp.policies.periodSeconds (int32), required

          periodSeconds specifies the window of time for which the policy should hold true. PeriodSeconds must be greater than zero and less than or equal to 1800 (30 min).

      • behavior.scaleUp.selectPolicy (string)

        selectPolicy is used to specify which policy should be used. If not set, the default value Max is used.

      • behavior.scaleUp.stabilizationWindowSeconds (int32)

        stabilizationWindowSeconds is the number of seconds for which past recommendations should be considered while scaling up or scaling down. StabilizationWindowSeconds must be greater than or equal to zero and less than or equal to 3600 (one hour). If not set, use the default values: - For scale up: 0 (i.e. no stabilization is done). - For scale down: 300 (i.e. the stabilization window is 300 seconds long).

  • metrics ([]MetricSpec)

    Atomic: will be replaced during a merge

    metrics contains the specifications for which to use to calculate the desired replica count (the maximum replica count across all metrics will be used). The desired replica count is calculated multiplying the ratio between the target value and the current value by the current number of pods.

15 - PodSchedulingContext v1alpha3

PodSchedulingContext objects hold information that is needed to schedule a Pod with ResourceClaims that use "WaitForFirstConsumer" allocation mode.

apiVersion: resource.k8s.io/v1alpha3

import "k8s.io/api/resource/v1alpha3"

PodSchedulingContext

PodSchedulingContext objects hold information that is needed to schedule a Pod with ResourceClaims that use "WaitForFirstConsumer" allocation mode.

This is an alpha type and requires enabling the DRAControlPlaneController feature gate.

PodSchedulingContextSpec

PodSchedulingContextSpec describes where resources for the Pod are needed.

  • potentialNodes ([]string)

    Atomic: will be replaced during a merge

    PotentialNodes lists nodes where the Pod might be able to run.

    The size of this field is limited to 128. This is large enough for many clusters. Larger clusters may need more attempts to find a node that suits all pending resources. This may get increased in the future, but not reduced.

  • selectedNode (string)

    SelectedNode is the node for which allocation of ResourceClaims that are referenced by the Pod and that use "WaitForFirstConsumer" allocation is to be attempted.

PodSchedulingContextStatus

PodSchedulingContextStatus describes where resources for the Pod can be allocated.

  • resourceClaims ([]ResourceClaimSchedulingStatus)

    Map: unique values on key name will be kept during a merge

    ResourceClaims describes resource availability for each pod.spec.resourceClaim entry where the corresponding ResourceClaim uses "WaitForFirstConsumer" allocation mode.

    ResourceClaimSchedulingStatus contains information about one particular ResourceClaim with "WaitForFirstConsumer" allocation mode.

    • resourceClaims.name (string), required

      Name matches the pod.spec.resourceClaims[*].Name field.

    • resourceClaims.unsuitableNodes ([]string)

      Atomic: will be replaced during a merge

      UnsuitableNodes lists nodes that the ResourceClaim cannot be allocated for.

      The size of this field is limited to 128, the same as for PodSchedulingSpec.PotentialNodes. This may get increased in the future, but not reduced.

PodSchedulingContextList

PodSchedulingContextList is a collection of Pod scheduling objects.

  • apiVersion: resource.k8s.io/v1alpha3

  • kind: PodSchedulingContextList

  • metadata (ListMeta)

    Standard list metadata

16 - ResourceClaim v1alpha3

ResourceClaim describes a request for access to resources in the cluster, for use by workloads.

apiVersion: resource.k8s.io/v1alpha3

import "k8s.io/api/resource/v1alpha3"

ResourceClaim

ResourceClaim describes a request for access to resources in the cluster, for use by workloads. For example, if a workload needs an accelerator device with specific properties, this is how that request is expressed. The status stanza tracks whether this claim has been satisfied and what specific resources have been allocated.

This is an alpha type and requires enabling the DynamicResourceAllocation feature gate.

  • apiVersion: resource.k8s.io/v1alpha3

  • kind: ResourceClaim

  • metadata (ObjectMeta)

    Standard object metadata

  • spec (ResourceClaimSpec), required

    Spec describes what is being requested and how to configure it. The spec is immutable.

  • status (ResourceClaimStatus)

    Status describes whether the claim is ready to use and what has been allocated.

ResourceClaimSpec

ResourceClaimSpec defines what is being requested in a ResourceClaim and how to configure it.

  • controller (string)

    Controller is the name of the DRA driver that is meant to handle allocation of this claim. If empty, allocation is handled by the scheduler while scheduling a pod.

    Must be a DNS subdomain and should end with a DNS domain owned by the vendor of the driver.

    This is an alpha field and requires enabling the DRAControlPlaneController feature gate.

  • devices (DeviceClaim)

    Devices defines how to request devices.

    DeviceClaim defines how to request devices with a ResourceClaim.

    • devices.config ([]DeviceClaimConfiguration)

      Atomic: will be replaced during a merge

      This field holds configuration for multiple potential drivers which could satisfy requests in this claim. It is ignored while allocating the claim.

      DeviceClaimConfiguration is used for configuration parameters in DeviceClaim.

      • devices.config.opaque (OpaqueDeviceConfiguration)

        Opaque provides driver-specific configuration parameters.

        OpaqueDeviceConfiguration contains configuration parameters for a driver in a format defined by the driver vendor.

        • devices.config.opaque.driver (string), required

          Driver is used to determine which kubelet plugin needs to be passed these configuration parameters.

          An admission policy provided by the driver developer could use this to decide whether it needs to validate them.

          Must be a DNS subdomain and should end with a DNS domain owned by the vendor of the driver.

        • devices.config.opaque.parameters (RawExtension), required

          Parameters can contain arbitrary data. It is the responsibility of the driver developer to handle validation and versioning. Typically this includes self-identification and a version ("kind" + "apiVersion" for Kubernetes types), with conversion between different versions.

          *RawExtension is used to hold extensions in external versions.

          To use this, make a field which has RawExtension as its type in your external, versioned struct, and Object in your internal struct. You also need to register your various plugin types.

          // Internal package:

          type MyAPIObject struct {
	runtime.TypeMeta `json:",inline"`
	MyPlugin runtime.Object `json:"myPlugin"`
}

type PluginA struct {
	AOption string `json:"aOption"`
}

          // External package:

          type MyAPIObject struct {
	runtime.TypeMeta `json:",inline"`
	MyPlugin runtime.RawExtension `json:"myPlugin"`
}

type PluginA struct {
	AOption string `json:"aOption"`
}

          // On the wire, the JSON will look something like this:

          {
	"kind":"MyAPIObject",
	"apiVersion":"v1",
	"myPlugin": {
		"kind":"PluginA",
		"aOption":"foo",
	},
}

          So what happens? Decode first uses json or yaml to unmarshal the serialized data into your external MyAPIObject. That causes the raw JSON to be stored, but not unpacked. The next step is to copy (using pkg/conversion) into the internal struct. The runtime package's DefaultScheme has conversion functions installed which will unpack the JSON stored in RawExtension, turning it into the correct object type, and storing it in the Object. (TODO: In the case where the object is of an unknown type, a runtime.Unknown object will be created and stored.)*

      • devices.config.requests ([]string)

        Atomic: will be replaced during a merge

        Requests lists the names of requests where the configuration applies. If empty, it applies to all requests.

    • devices.constraints ([]DeviceConstraint)

      Atomic: will be replaced during a merge

      These constraints must be satisfied by the set of devices that get allocated for the claim.

      DeviceConstraint must have exactly one field set besides Requests.

      • devices.constraints.matchAttribute (string)

        MatchAttribute requires that all devices in question have this attribute and that its type and value are the same across those devices.

        For example, if you specified "dra.example.com/numa" (a hypothetical example!), then only devices in the same NUMA node will be chosen. A device which does not have that attribute will not be chosen. All devices should use a value of the same type for this attribute because that is part of its specification, but if one device doesn't, then it also will not be chosen.

        Must include the domain qualifier.

      • devices.constraints.requests ([]string)

        Atomic: will be replaced during a merge

        Requests is a list of the one or more requests in this claim which must co-satisfy this constraint. If a request is fulfilled by multiple devices, then all of the devices must satisfy the constraint. If this is not specified, this constraint applies to all requests in this claim.

    • devices.requests ([]DeviceRequest)

      Atomic: will be replaced during a merge

      Requests represent individual requests for distinct devices which must all be satisfied. If empty, nothing needs to be allocated.

      *DeviceRequest is a request for devices required for a claim. This is typically a request for a single resource like a device, but can also ask for several identical devices.

      A DeviceClassName is currently required. Clients must check that it is indeed set. It's absence indicates that something changed in a way that is not supported by the client yet, in which case it must refuse to handle the request.*

      • devices.requests.deviceClassName (string), required

        DeviceClassName references a specific DeviceClass, which can define additional configuration and selectors to be inherited by this request.

        A class is required. Which classes are available depends on the cluster.

        Administrators may use this to restrict which devices may get requested by only installing classes with selectors for permitted devices. If users are free to request anything without restrictions, then administrators can create an empty DeviceClass for users to reference.

      • devices.requests.name (string), required

        Name can be used to reference this request in a pod.spec.containers[].resources.claims entry and in a constraint of the claim.

        Must be a DNS label.

      • devices.requests.adminAccess (boolean)

        AdminAccess indicates that this is a claim for administrative access to the device(s). Claims with AdminAccess are expected to be used for monitoring or other management services for a device. They ignore all ordinary claims to the device with respect to access modes and any resource allocations.

      • devices.requests.allocationMode (string)

        AllocationMode and its related fields define how devices are allocated to satisfy this request. Supported values are:

        • ExactCount: This request is for a specific number of devices. This is the default. The exact number is provided in the count field.

        • All: This request is for all of the matching devices in a pool. Allocation will fail if some devices are already allocated, unless adminAccess is requested.

        If AlloctionMode is not specified, the default mode is ExactCount. If the mode is ExactCount and count is not specified, the default count is one. Any other requests must specify this field.

        More modes may get added in the future. Clients must refuse to handle requests with unknown modes.

      • devices.requests.count (int64)

        Count is used only when the count mode is "ExactCount". Must be greater than zero. If AllocationMode is ExactCount and this field is not specified, the default is one.

      • devices.requests.selectors ([]DeviceSelector)

        Atomic: will be replaced during a merge

        Selectors define criteria which must be satisfied by a specific device in order for that device to be considered for this request. All selectors must be satisfied for a device to be considered.

        DeviceSelector must have exactly one field set.

        • devices.requests.selectors.cel (CELDeviceSelector)

          CEL contains a CEL expression for selecting a device.

          CELDeviceSelector contains a CEL expression for selecting a device.

          • devices.requests.selectors.cel.expression (string), required

            Expression is a CEL expression which evaluates a single device. It must evaluate to true when the device under consideration satisfies the desired criteria, and false when it does not. Any other result is an error and causes allocation of devices to abort.

            The expression's input is an object named "device", which carries the following properties:

            • driver (string): the name of the driver which defines this device.
            • attributes (map[string]object): the device's attributes, grouped by prefix (e.g. device.attributes["dra.example.com"] evaluates to an object with all of the attributes which were prefixed by "dra.example.com".
            • capacity (map[string]object): the device's capacities, grouped by prefix.

            Example: Consider a device with driver="dra.example.com", which exposes two attributes named "model" and "ext.example.com/family" and which exposes one capacity named "modules". This input to this expression would have the following fields:

            device.driver
device.attributes["dra.example.com"].model
device.attributes["ext.example.com"].family
device.capacity["dra.example.com"].modules

            The device.driver field can be used to check for a specific driver, either as a high-level precondition (i.e. you only want to consider devices from this driver) or as part of a multi-clause expression that is meant to consider devices from different drivers.

            The value type of each attribute is defined by the device definition, and users who write these expressions must consult the documentation for their specific drivers. The value type of each capacity is Quantity.

            If an unknown prefix is used as a lookup in either device.attributes or device.capacity, an empty map will be returned. Any reference to an unknown field will cause an evaluation error and allocation to abort.

            A robust expression should check for the existence of attributes before referencing them.

            For ease of use, the cel.bind() function is enabled, and can be used to simplify expressions that access multiple attributes with the same domain. For example:

            cel.bind(dra, device.attributes["dra.example.com"], dra.someBool && dra.anotherBool)

ResourceClaimStatus

ResourceClaimStatus tracks whether the resource has been allocated and what the result of that was.

  • allocation (AllocationResult)

    Allocation is set once the claim has been allocated successfully.

    AllocationResult contains attributes of an allocated resource.

    • allocation.controller (string)

      Controller is the name of the DRA driver which handled the allocation. That driver is also responsible for deallocating the claim. It is empty when the claim can be deallocated without involving a driver.

      A driver may allocate devices provided by other drivers, so this driver name here can be different from the driver names listed for the results.

      This is an alpha field and requires enabling the DRAControlPlaneController feature gate.

    • allocation.devices (DeviceAllocationResult)

      Devices is the result of allocating devices.

      DeviceAllocationResult is the result of allocating devices.

      • allocation.devices.config ([]DeviceAllocationConfiguration)

        Atomic: will be replaced during a merge

        This field is a combination of all the claim and class configuration parameters. Drivers can distinguish between those based on a flag.

        This includes configuration parameters for drivers which have no allocated devices in the result because it is up to the drivers which configuration parameters they support. They can silently ignore unknown configuration parameters.

        DeviceAllocationConfiguration gets embedded in an AllocationResult.

        • allocation.devices.config.source (string), required

          Source records whether the configuration comes from a class and thus is not something that a normal user would have been able to set or from a claim.

        • allocation.devices.config.opaque (OpaqueDeviceConfiguration)

          Opaque provides driver-specific configuration parameters.

          OpaqueDeviceConfiguration contains configuration parameters for a driver in a format defined by the driver vendor.

          • allocation.devices.config.opaque.driver (string), required

            Driver is used to determine which kubelet plugin needs to be passed these configuration parameters.

            An admission policy provided by the driver developer could use this to decide whether it needs to validate them.

            Must be a DNS subdomain and should end with a DNS domain owned by the vendor of the driver.

          • allocation.devices.config.opaque.parameters (RawExtension), required

            Parameters can contain arbitrary data. It is the responsibility of the driver developer to handle validation and versioning. Typically this includes self-identification and a version ("kind" + "apiVersion" for Kubernetes types), with conversion between different versions.

            *RawExtension is used to hold extensions in external versions.

            To use this, make a field which has RawExtension as its type in your external, versioned struct, and Object in your internal struct. You also need to register your various plugin types.

            // Internal package:

            type MyAPIObject struct { runtime.TypeMeta json:",inline" MyPlugin runtime.Object json:"myPlugin" }

            type PluginA struct { AOption string json:"aOption" }

            // External package:

            type MyAPIObject struct { runtime.TypeMeta json:",inline" MyPlugin runtime.RawExtension json:"myPlugin" }

            type PluginA struct { AOption string json:"aOption" }

            // On the wire, the JSON will look something like this:

            { "kind":"MyAPIObject", "apiVersion":"v1", "myPlugin": { "kind":"PluginA", "aOption":"foo", }, }

            So what happens? Decode first uses json or yaml to unmarshal the serialized data into your external MyAPIObject. That causes the raw JSON to be stored, but not unpacked. The next step is to copy (using pkg/conversion) into the internal struct. The runtime package's DefaultScheme has conversion functions installed which will unpack the JSON stored in RawExtension, turning it into the correct object type, and storing it in the Object. (TODO: In the case where the object is of an unknown type, a runtime.Unknown object will be created and stored.)*

        • allocation.devices.config.requests ([]string)

          Atomic: will be replaced during a merge

          Requests lists the names of requests where the configuration applies. If empty, its applies to all requests.

      • allocation.devices.results ([]DeviceRequestAllocationResult)

        Atomic: will be replaced during a merge

        Results lists all allocated devices.

        DeviceRequestAllocationResult contains the allocation result for one request.

        • allocation.devices.results.device (string), required

          Device references one device instance via its name in the driver's resource pool. It must be a DNS label.

        • allocation.devices.results.driver (string), required

          Driver specifies the name of the DRA driver whose kubelet plugin should be invoked to process the allocation once the claim is needed on a node.

          Must be a DNS subdomain and should end with a DNS domain owned by the vendor of the driver.

        • allocation.devices.results.pool (string), required

          This name together with the driver name and the device name field identify which device was allocated (\<driver name>/\<pool name>/\<device name>).

          Must not be longer than 253 characters and may contain one or more DNS sub-domains separated by slashes.

        • allocation.devices.results.request (string), required

          Request is the name of the request in the claim which caused this device to be allocated. Multiple devices may have been allocated per request.

    • allocation.nodeSelector (NodeSelector)

      NodeSelector defines where the allocated resources are available. If unset, they are available everywhere.

      A node selector represents the union of the results of one or more label queries over a set of nodes; that is, it represents the OR of the selectors represented by the node selector terms.

      • allocation.nodeSelector.nodeSelectorTerms ([]NodeSelectorTerm), required

        Atomic: will be replaced during a merge

        Required. A list of node selector terms. The terms are ORed.

        A null or empty node selector term matches no objects. The requirements of them are ANDed. The TopologySelectorTerm type implements a subset of the NodeSelectorTerm.

        • allocation.nodeSelector.nodeSelectorTerms.matchExpressions ([]NodeSelectorRequirement)

          Atomic: will be replaced during a merge

          A list of node selector requirements by node's labels.

        • allocation.nodeSelector.nodeSelectorTerms.matchFields ([]NodeSelectorRequirement)

          Atomic: will be replaced during a merge

          A list of node selector requirements by node's fields.

  • deallocationRequested (boolean)

    Indicates that a claim is to be deallocated. While this is set, no new consumers may be added to ReservedFor.

    This is only used if the claim needs to be deallocated by a DRA driver. That driver then must deallocate this claim and reset the field together with clearing the Allocation field.

    This is an alpha field and requires enabling the DRAControlPlaneController feature gate.

  • reservedFor ([]ResourceClaimConsumerReference)

    Patch strategy: merge on key uid

    Map: unique values on key uid will be kept during a merge

    ReservedFor indicates which entities are currently allowed to use the claim. A Pod which references a ResourceClaim which is not reserved for that Pod will not be started. A claim that is in use or might be in use because it has been reserved must not get deallocated.

    In a cluster with multiple scheduler instances, two pods might get scheduled concurrently by different schedulers. When they reference the same ResourceClaim which already has reached its maximum number of consumers, only one pod can be scheduled.

    Both schedulers try to add their pod to the claim.status.reservedFor field, but only the update that reaches the API server first gets stored. The other one fails with an error and the scheduler which issued it knows that it must put the pod back into the queue, waiting for the ResourceClaim to become usable again.

    There can be at most 32 such reservations. This may get increased in the future, but not reduced.

    ResourceClaimConsumerReference contains enough information to let you locate the consumer of a ResourceClaim. The user must be a resource in the same namespace as the ResourceClaim.

    • reservedFor.name (string), required

      Name is the name of resource being referenced.

    • reservedFor.resource (string), required

      Resource is the type of resource being referenced, for example "pods".

    • reservedFor.uid (string), required

      UID identifies exactly one incarnation of the resource.

    • reservedFor.apiGroup (string)

      APIGroup is the group for the resource being referenced. It is empty for the core API. This matches the group in the APIVersion that is used when creating the resources.

ResourceClaimList

ResourceClaimList is a collection of claims.

  • apiVersion: resource.k8s.io/v1alpha3

18 - ResourceSlice v1alpha3

ResourceSlice represents one or more resources in a pool of similar resources, managed by a common driver.

apiVersion: resource.k8s.io/v1alpha3

import "k8s.io/api/resource/v1alpha3"

ResourceSlice

ResourceSlice represents one or more resources in a pool of similar resources, managed by a common driver. A pool may span more than one ResourceSlice, and exactly how many ResourceSlices comprise a pool is determined by the driver.

At the moment, the only supported resources are devices with attributes and capacities. Each device in a given pool, regardless of how many ResourceSlices, must have a unique name. The ResourceSlice in which a device gets published may change over time. The unique identifier for a device is the tuple <driver name>, <pool name>, <device name>.

Whenever a driver needs to update a pool, it increments the pool.Spec.Pool.Generation number and updates all ResourceSlices with that new number and new resource definitions. A consumer must only use ResourceSlices with the highest generation number and ignore all others.

When allocating all resources in a pool matching certain criteria or when looking for the best solution among several different alternatives, a consumer should check the number of ResourceSlices in a pool (included in each ResourceSlice) to determine whether its view of a pool is complete and if not, should wait until the driver has completed updating the pool.

For resources that are not local to a node, the node name is not set. Instead, the driver may use a node selector to specify where the devices are available.

This is an alpha type and requires enabling the DynamicResourceAllocation feature gate.

  • apiVersion: resource.k8s.io/v1alpha3

  • kind: ResourceSlice

  • metadata (ObjectMeta)

    Standard object metadata

  • spec (ResourceSliceSpec), required

    Contains the information published by the driver.

    Changing the spec automatically increments the metadata.generation number.

ResourceSliceSpec

ResourceSliceSpec contains the information published by the driver in one ResourceSlice.

  • driver (string), required

    Driver identifies the DRA driver providing the capacity information. A field selector can be used to list only ResourceSlice objects with a certain driver name.

    Must be a DNS subdomain and should end with a DNS domain owned by the vendor of the driver. This field is immutable.

  • pool (ResourcePool), required

    Pool describes the pool that this ResourceSlice belongs to.

    ResourcePool describes the pool that ResourceSlices belong to.

    • pool.generation (int64), required

      Generation tracks the change in a pool over time. Whenever a driver changes something about one or more of the resources in a pool, it must change the generation in all ResourceSlices which are part of that pool. Consumers of ResourceSlices should only consider resources from the pool with the highest generation number. The generation may be reset by drivers, which should be fine for consumers, assuming that all ResourceSlices in a pool are updated to match or deleted.

      Combined with ResourceSliceCount, this mechanism enables consumers to detect pools which are comprised of multiple ResourceSlices and are in an incomplete state.

    • pool.name (string), required

      Name is used to identify the pool. For node-local devices, this is often the node name, but this is not required.

      It must not be longer than 253 characters and must consist of one or more DNS sub-domains separated by slashes. This field is immutable.

    • pool.resourceSliceCount (int64), required

      ResourceSliceCount is the total number of ResourceSlices in the pool at this generation number. Must be greater than zero.

      Consumers can use this to check whether they have seen all ResourceSlices belonging to the same pool.

  • allNodes (boolean)

    AllNodes indicates that all nodes have access to the resources in the pool.

    Exactly one of NodeName, NodeSelector and AllNodes must be set.

  • devices ([]Device)

    Atomic: will be replaced during a merge

    Devices lists some or all of the devices in this pool.

    Must not have more than 128 entries.

    Device represents one individual hardware instance that can be selected based on its attributes. Besides the name, exactly one field must be set.

    • devices.name (string), required

      Name is unique identifier among all devices managed by the driver in the pool. It must be a DNS label.

    • devices.basic (BasicDevice)

      Basic defines one device instance.

      BasicDevice defines one device instance.

      • devices.basic.attributes (map[string]DeviceAttribute)

        Attributes defines the set of attributes for this device. The name of each attribute must be unique in that set.

        The maximum number of attributes and capacities combined is 32.

        DeviceAttribute must have exactly one field set.

        • devices.basic.attributes.bool (boolean)

          BoolValue is a true/false value.

        • devices.basic.attributes.int (int64)

          IntValue is a number.

        • devices.basic.attributes.string (string)

          StringValue is a string. Must not be longer than 64 characters.

        • devices.basic.attributes.version (string)

          VersionValue is a semantic version according to semver.org spec 2.0.0. Must not be longer than 64 characters.

      • devices.basic.capacity (map[string]Quantity)

        Capacity defines the set of capacities for this device. The name of each capacity must be unique in that set.

        The maximum number of attributes and capacities combined is 32.

  • nodeName (string)

    NodeName identifies the node which provides the resources in this pool. A field selector can be used to list only ResourceSlice objects belonging to a certain node.

    This field can be used to limit access from nodes to ResourceSlices with the same node name. It also indicates to autoscalers that adding new nodes of the same type as some old node might also make new resources available.

    Exactly one of NodeName, NodeSelector and AllNodes must be set. This field is immutable.

  • nodeSelector (NodeSelector)

    NodeSelector defines which nodes have access to the resources in the pool, when that pool is not limited to a single node.

    Must use exactly one term.

    Exactly one of NodeName, NodeSelector and AllNodes must be set.

    A node selector represents the union of the results of one or more label queries over a set of nodes; that is, it represents the OR of the selectors represented by the node selector terms.

    • nodeSelector.nodeSelectorTerms ([]NodeSelectorTerm), required

      Atomic: will be replaced during a merge

      Required. A list of node selector terms. The terms are ORed.

      A null or empty node selector term matches no objects. The requirements of them are ANDed. The TopologySelectorTerm type implements a subset of the NodeSelectorTerm.

      • nodeSelector.nodeSelectorTerms.matchExpressions ([]NodeSelectorRequirement)

        Atomic: will be replaced during a merge

        A list of node selector requirements by node's labels.

      • nodeSelector.nodeSelectorTerms.matchFields ([]NodeSelectorRequirement)

        Atomic: will be replaced during a merge

        A list of node selector requirements by node's fields.
