RunInstances
Launches the specified number of instances using an AMI for which you have permissions.
You can specify a number of options, or leave the default options. The following rules apply:
-
If you don't specify a subnet ID, we choose a default subnet from your default VPC for you. If you don't have a default VPC, you must specify a subnet ID in the request.
-
All instances have a network interface with a primary private IPv4 address. If you don't specify this address, we choose one from the IPv4 range of your subnet.
-
Not all instance types support IPv6 addresses. For more information, see Instance types.
-
If you don't specify a security group ID, we use the default security group for the VPC. For more information, see Security groups.
-
If any of the AMIs have a product code attached for which the user has not subscribed, the request fails.
You can create a launch template, which is a resource that contains the parameters to launch an instance. When you launch an instance using RunInstances, you can specify the launch template instead of specifying the launch parameters.
To ensure faster instance launches, break up large requests into smaller batches. For example, create five separate launch requests for 100 instances each instead of one launch request for 500 instances.
RunInstances
is subject to both request rate limiting and resource rate
limiting. For more information, see Request throttling.
An instance is ready for you to use when it's in the running
state. You
can check the state of your instance using DescribeInstances. You can
tag instances and EBS volumes during launch, after launch, or both. For more
information, see CreateTags and Tagging your Amazon EC2
resources.
Linux instances have access to the public key of the key pair at boot. You can use this key to provide secure access to the instance. Amazon EC2 public images use this feature to provide secure access without passwords. For more information, see Key pairs.
For troubleshooting, see What to do if an instance immediately terminates, and Troubleshooting connecting to your instance.
Request Parameters
The following parameters are for this specific action. For more information about required and optional parameters that are common to all actions, see Common Query Parameters.
- AdditionalInfo
-
Reserved.
Type: String
Required: No
- BlockDeviceMapping.N
-
The block device mapping, which defines the EBS volumes and instance store volumes to attach to the instance at launch. For more information, see Block device mappings in the Amazon EC2 User Guide.
Type: Array of BlockDeviceMapping objects
Required: No
- CapacityReservationSpecification
-
Information about the Capacity Reservation targeting option. If you do not specify this parameter, the instance's Capacity Reservation preference defaults to
open
, which enables it to run in any open Capacity Reservation that has matching attributes (instance type, platform, Availability Zone).Type: CapacityReservationSpecification object
Required: No
- ClientToken
-
Unique, case-sensitive identifier you provide to ensure the idempotency of the request. If you do not specify a client token, a randomly generated token is used for the request to ensure idempotency.
For more information, see Ensuring Idempotency.
Constraints: Maximum 64 ASCII characters
Type: String
Required: No
- CpuOptions
-
The CPU options for the instance. For more information, see Optimize CPU options in the Amazon EC2 User Guide.
Type: CpuOptionsRequest object
Required: No
- CreditSpecification
-
The credit option for CPU usage of the burstable performance instance. Valid values are
standard
andunlimited
. To change this attribute after launch, use ModifyInstanceCreditSpecification. For more information, see Burstable performance instances in the Amazon EC2 User Guide.Default:
standard
(T2 instances) orunlimited
(T3/T3a/T4g instances)For T3 instances with
host
tenancy, onlystandard
is supported.Type: CreditSpecificationRequest object
Required: No
- DisableApiStop
-
Indicates whether an instance is enabled for stop protection. For more information, see Stop protection.
Type: Boolean
Required: No
- DisableApiTermination
-
If you set this parameter to
true
, you can't terminate the instance using the Amazon EC2 console, CLI, or API; otherwise, you can. To change this attribute after launch, use ModifyInstanceAttribute. Alternatively, if you setInstanceInitiatedShutdownBehavior
toterminate
, you can terminate the instance by running the shutdown command from the instance.Default:
false
Type: Boolean
Required: No
- DryRun
-
Checks whether you have the required permissions for the action, without actually making the request, and provides an error response. If you have the required permissions, the error response is
DryRunOperation
. Otherwise, it isUnauthorizedOperation
.Type: Boolean
Required: No
- EbsOptimized
-
Indicates whether the instance is optimized for Amazon EBS I/O. This optimization provides dedicated throughput to Amazon EBS and an optimized configuration stack to provide optimal Amazon EBS I/O performance. This optimization isn't available with all instance types. Additional usage charges apply when using an EBS-optimized instance.
Default:
false
Type: Boolean
Required: No
- ElasticGpuSpecification.N
-
An elastic GPU to associate with the instance.
Note
Amazon Elastic Graphics reached end of life on January 8, 2024.
Type: Array of ElasticGpuSpecification objects
Required: No
- ElasticInferenceAccelerator.N
-
An elastic inference accelerator to associate with the instance.
Note
Amazon Elastic Inference (EI) is no longer available to new customers. For more information, see Amazon Elastic Inference FAQs
. Type: Array of ElasticInferenceAccelerator objects
Required: No
- EnablePrimaryIpv6
-
If you’re launching an instance into a dual-stack or IPv6-only subnet, you can enable assigning a primary IPv6 address. A primary IPv6 address is an IPv6 GUA address associated with an ENI that you have enabled to use a primary IPv6 address. Use this option if an instance relies on its IPv6 address not changing. When you launch the instance, AWS will automatically assign an IPv6 address associated with the ENI attached to your instance to be the primary IPv6 address. Once you enable an IPv6 GUA address to be a primary IPv6, you cannot disable it. When you enable an IPv6 GUA address to be a primary IPv6, the first IPv6 GUA will be made the primary IPv6 address until the instance is terminated or the network interface is detached. If you have multiple IPv6 addresses associated with an ENI attached to your instance and you enable a primary IPv6 address, the first IPv6 GUA address associated with the ENI becomes the primary IPv6 address.
Type: Boolean
Required: No
- EnclaveOptions
-
Indicates whether the instance is enabled for AWS Nitro Enclaves. For more information, see What is AWS Nitro Enclaves? in the AWS Nitro Enclaves User Guide.
You can't enable AWS Nitro Enclaves and hibernation on the same instance.

Required: No
- HibernationOptions
-
Indicates whether an instance is enabled for hibernation. This parameter is valid only if the instance meets the hibernation prerequisites. For more information, see Hibernate your Amazon EC2 instance in the Amazon EC2 User Guide.
