A container instance.
| Attribute | Type | Description | Examples | Stability |
|---|---|---|---|---|
container.command |
string | The command used to run the container (i.e. the command name). [1] | otelcontribcol |
|
container.command_args |
string[] | All the command arguments (including the command/executable itself) run by the container. [2] | ["otelcontribcol", "--config", "config.yaml"] |
|
container.command_line |
string | The full command run by the container as a single string representing the full command. [2] | otelcontribcol --config config.yaml |
|
container.id |
string | Container ID. Usually a UUID, as for example used to identify Docker containers. The UUID might be abbreviated. | a3bf90e006b2 |
|
container.image.id |
string | Runtime specific image identifier. Usually a hash algorithm followed by a UUID. [2] | sha256:19c92d0a00d1b66d897bceaa7319bee0dd38a10a851c60bcec9474aa3f01e50f |
|
container.image.name |
string | Name of the image the container was built on. | gcr.io/opentelemetry/operator |
|
container.image.repo_digests |
string[] | Repo digests of the container image as provided by the container runtime. [3] | ["example@sha256:afcc7f1ac1b49db317a7196c902e61c6c3c4607d63599ee1a82d702d249a0ccb", "internal.registry.example.com:5000/example@sha256:b69959407d21e8a062e0416bf13405bb2b71ed7a84dde4158ebafacfa06f5578"] |
|
container.image.tags |
string[] | Container image tags. An example can be found in Docker Image Inspect. Should be only the <tag> section of the full name for example from registry.example.com/my-org/my-image:<tag>. |
["v1.27.1", "3.5.7-0"] |
|
container.label.<key> |
string | Container labels, <key> being the label name, the value being the label value. |
container.label.app=nginx |
|
container.name |
string | Container name used by container runtime. | opentelemetry-autoconf |
|
container.runtime |
string | The container runtime managing this container. | docker; containerd; rkt |
[1]: If using embedded credentials or sensitive data, it is recommended to remove them to prevent potential leakage.
[2]: Docker defines a sha256 of the image id; container.image.id corresponds to the Image field from the Docker container inspect API endpoint.
K8s defines a link to the container registry repository with digest "imageID": "registry.azurecr.io /namespace/service/dockerfile@sha256:bdeabd40c3a8a492eaf9e8e44d0ebbb84bac7ee25ac0cf8a7159d25f62555625".
The ID is assigned by the container runtime and can vary in different environments. Consider using oci.manifest.digest if it is important to identify the same image in different environments/runtimes.
[3]: Docker and CRI report those under the RepoDigests field.
Describes deprecated container attributes.
| Attribute | Type | Description | Examples | Stability |
|---|---|---|---|---|
container.cpu.state |
string | Deprecated, use cpu.mode instead. |
user; kernel |
Replaced by cpu.mode |
container.labels.<key> |
string | Deprecated, use container.label instead. |
container.label.app=nginx |
Replaced by container.label. |
container.cpu.state has the following list of well-known values. If one of them applies, then the respective value MUST be used; otherwise, a custom value MAY be used.
| Value | Description | Stability |
|---|---|---|
kernel |
When tasks of the cgroup are in kernel mode (Linux). When all container processes are in kernel mode (Windows). | |
system |
When CPU is used by the system (host OS) | |
user |
When tasks of the cgroup are in user mode (Linux). When all container processes are in user mode (Windows). |
