run-task¶

Description¶

Starts a new task using the specified task definition.

Note

On March 21, 2024, a change was made to resolve the task definition revision before authorization. When a task definition revision is not specified, authorization will occur using the latest revision of a task definition.

Note

Amazon Elastic Inference (EI) is no longer available to customers.

You can allow Amazon ECS to place tasks for you, or you can customize how Amazon ECS places tasks using placement constraints and placement strategies. For more information, see Scheduling Tasks in the Amazon Elastic Container Service Developer Guide .

Alternatively, you can use StartTask to use your own scheduler or place tasks manually on specific container instances.

You can attach Amazon EBS volumes to Amazon ECS tasks by configuring the volume when creating or updating a service. For more infomation, see Amazon EBS volumes in the Amazon Elastic Container Service Developer Guide .

The Amazon ECS API follows an eventual consistency model. This is because of the distributed nature of the system supporting the API. This means that the result of an API command you run that affects your Amazon ECS resources might not be immediately visible to all subsequent commands you run. Keep this in mind when you carry out an API command that immediately follows a previous API command.

To manage eventual consistency, you can do the following:

Confirm the state of the resource before you run a command to modify it. Run the DescribeTasks command using an exponential backoff algorithm to ensure that you allow enough time for the previous command to propagate through the system. To do this, run the DescribeTasks command repeatedly, starting with a couple of seconds of wait time and increasing gradually up to five minutes of wait time.
Add wait time between subsequent commands, even if the DescribeTasks command returns an accurate response. Apply an exponential backoff algorithm starting with a couple of seconds of wait time, and increase gradually up to about five minutes of wait time.

Options¶

--capacity-provider-strategy (list)

The capacity provider strategy to use for the task.

If a capacityProviderStrategy is specified, the launchType parameter must be omitted. If no capacityProviderStrategy or launchType is specified, the defaultCapacityProviderStrategy for the cluster is used.

When you use cluster auto scaling, you must specify capacityProviderStrategy and not launchType .

A capacity provider strategy may contain a maximum of 6 capacity providers.

(structure)

The details of a capacity provider strategy. A capacity provider strategy can be set when using the RunTask or CreateCluster APIs or as the default capacity provider strategy for a cluster with the CreateCluster API.

Only capacity providers that are already associated with a cluster and have an ACTIVE or UPDATING status can be used in a capacity provider strategy. The PutClusterCapacityProviders API is used to associate a capacity provider with a cluster.

If specifying a capacity provider that uses an Auto Scaling group, the capacity provider must already be created. New Auto Scaling group capacity providers can be created with the CreateClusterCapacityProvider API operation.

To use a Fargate capacity provider, specify either the FARGATE or FARGATE_SPOT capacity providers. The Fargate capacity providers are available to all accounts and only need to be associated with a cluster to be used in a capacity provider strategy.

With FARGATE_SPOT , you can run interruption tolerant tasks at a rate that’s discounted compared to the FARGATE price. FARGATE_SPOT runs tasks on spare compute capacity. When Amazon Web Services needs the capacity back, your tasks are interrupted with a two-minute warning. FARGATE_SPOT supports Linux tasks with the X86_64 architecture on platform version 1.3.0 or later. FARGATE_SPOT supports Linux tasks with the ARM64 architecture on platform version 1.4.0 or later.

A capacity provider strategy may contain a maximum of 6 capacity providers.

capacityProvider -> (string)

The short name of the capacity provider.

weight -> (integer)

The weight value designates the relative percentage of the total number of tasks launched that should use the specified capacity provider. The weight value is taken into consideration after the base value, if defined, is satisfied.

If no weight value is specified, the default value of 0 is used. When multiple capacity providers are specified within a capacity provider strategy, at least one of the capacity providers must have a weight value greater than zero and any capacity providers with a weight of 0 can’t be used to place tasks. If you specify multiple capacity providers in a strategy that all have a weight of 0 , any RunTask or CreateService actions using the capacity provider strategy will fail.

An example scenario for using weights is defining a strategy that contains two capacity providers and both have a weight of 1 , then when the base is satisfied, the tasks will be split evenly across the two capacity providers. Using that same logic, if you specify a weight of 1 for capacityProviderA and a weight of 4 for capacityProviderB , then for every one task that’s run using capacityProviderA , four tasks would use capacityProviderB .

base -> (integer)

The base value designates how many tasks, at a minimum, to run on the specified capacity provider. Only one capacity provider in a capacity provider strategy can have a base defined. If no value is specified, the default value of 0 is used.

Shorthand Syntax:

capacityProvider=string,weight=integer,base=integer ...

--enable-ecs-managed-tags | --no-enable-ecs-managed-tags (boolean)

Specifies whether to use Amazon ECS managed tags for the task. For more information, see Tagging Your Amazon ECS Resources in the Amazon Elastic Container Service Developer Guide .

--enable-execute-command | --disable-execute-command (boolean)

Determines whether to use the execute command functionality for the containers in this task. If true , this enables execute command functionality on all containers in the task.

If true , then the task definition must have a task role, or you must provide one as an override.

--group (string)

The name of the task group to associate with the task. The default value is the family name of the task definition (for example, family:my-family-name ).

--launch-type (string)

The infrastructure to run your standalone task on. For more information, see Amazon ECS launch types in the Amazon Elastic Container Service Developer Guide .

The FARGATE launch type runs your tasks on Fargate On-Demand infrastructure.

Note
Fargate Spot infrastructure is available for use but a capacity provider strategy must be used. For more information, see Fargate capacity providers in the Amazon ECS Developer Guide .

The EC2 launch type runs your tasks on Amazon EC2 instances registered to your cluster.

The EXTERNAL launch type runs your tasks on your on-premises server or virtual machine (VM) capacity registered to your cluster.

A task can use either a launch type or a capacity provider strategy. If a launchType is specified, the capacityProviderStrategy parameter must be omitted.

When you use cluster auto scaling, you must specify capacityProviderStrategy and not launchType .

Possible values:

EC2

FARGATE

EXTERNAL

--network-configuration (structure)

awsvpcConfiguration -> (structure)

The VPC subnets and security groups that are associated with a task.

Note
All specified subnets and security groups must be from the same VPC.

subnets -> (list)

JSON Syntax:

{
  "awsvpcConfiguration": {
    "subnets": ["string", ...],
    "securityGroups": ["string", ...],
    "assignPublicIp": "ENABLED"|"DISABLED"
  }
}

--overrides (structure)

A list of container overrides in JSON format that specify the name of a container in the specified task definition and the overrides it should receive. You can override the default command for a container (that’s specified in the task definition or Docker image) with a command override. You can also override existing environment variables (that are specified in the task definition or Docker image) on a container or add new environment variables to it with an environment override.

A total of 8192 characters are allowed for overrides. This limit includes the JSON formatting characters of the override structure.

containerOverrides -> (list)

One or more container overrides that are sent to a task.

(structure)

The overrides that are sent to a container. An empty container override can be passed in. An example of an empty container override is {"containerOverrides": [ ] } . If a non-empty container override is specified, the name parameter must be included.

You can use Secrets Manager or Amazon Web Services Systems Manager Parameter Store to store the sensitive data. For more information, see Retrieve secrets through environment variables in the Amazon ECS Developer Guide.

name -> (string)

(structure)

A list of files containing the environment variables to pass to a container. You can specify up to ten environment files. The file must have a .env file extension. Each line in an environment file should contain an environment variable in VARIABLE=VALUE format. Lines beginning with # are treated as comments and are ignored.

If there are environment variables specified using the environment parameter in a container definition, they take precedence over the variables contained within an environment file. If multiple environment files are specified that contain the same variable, they’re processed from the top down. We recommend that you use unique variable names. For more information, see Use a file to pass environment variables to a container in the Amazon Elastic Container Service Developer Guide .

Environment variable files are objects in Amazon S3 and all Amazon S3 security considerations apply.

You must use the following platforms for the Fargate launch type:

Linux platform version 1.4.0 or later.

Windows platform version 1.0.0 or later.

Consider the following when using the Fargate launch type:

The file is handled like a native Docker env-file.

An object representing a constraint on task placement. For more information, see Task placement constraints in the Amazon Elastic Container Service Developer Guide .

Note
If you’re using the Fargate launch type, task placement constraints aren’t supported.

type -> (string)

The type of constraint. Use distinctInstance to ensure that each task in a particular group is running on a different container instance. Use memberOf to restrict the selection to a group of valid candidates.

expression -> (string)

A cluster query language expression to apply to the constraint. The expression can have a maximum length of 2000 characters. You can’t specify an expression if the constraint type is distinctInstance . For more information, see Cluster query language in the Amazon Elastic Container Service Developer Guide .

(structure)

The task placement strategy for a task or service. For more information, see Task placement strategies in the Amazon Elastic Container Service Developer Guide .

type -> (string)

The type of placement strategy. The random placement strategy randomly places tasks on available candidates. The spread placement strategy spreads placement across available candidates evenly based on the field parameter. The binpack strategy places tasks on available candidates that have the least available amount of the resource that’s specified with the field parameter. For example, if you binpack on memory, a task is placed on the instance with the least amount of remaining memory but still enough to run the task.

field -> (string)

The field to apply the placement strategy against. For the spread placement strategy, valid values are instanceId (or host , which has the same effect), or any platform or custom attribute that’s applied to a container instance, such as attribute:ecs.availability-zone . For the binpack placement strategy, valid values are cpu and memory . For the random placement strategy, this field is not used.

--propagate-tags (string)

Specifies whether to propagate the tags from the task definition to the task. If no value is specified, the tags aren’t propagated. Tags can only be propagated to the task during task creation. To add tags to a task after task creation, use the`TagResource <https://docs.aws.amazon.com/AmazonECS/latest/APIReference/API_TagResource.html>`__ API action.

Note
An error will be received if you specify the SERVICE option when running a task.

Possible values:

TASK_DEFINITION

SERVICE

NONE

--reference-id (string)

This parameter is only used by Amazon ECS. It is not intended for use by customers.

--started-by (string)

An optional tag specified when a task is started. For example, if you automatically trigger a task to run a batch process job, you could apply a unique identifier for that job to your task with the startedBy parameter. You can then identify which tasks belong to that job by filtering the results of a ListTasks call with the startedBy value. Up to 128 letters (uppercase and lowercase), numbers, hyphens (-), forward slash (/), and underscores (_) are allowed.

If a task is started by an Amazon ECS service, then the startedBy parameter contains the deployment ID of the service that starts it.

--tags (list)

The metadata that you apply to the task to help you categorize and organize them. Each tag consists of a key and an optional value, both of which you define.

The following basic restrictions apply to tags:

For each resource, each tag key must be unique, and each tag key can have only one value.

Maximum key length - 128 Unicode characters in UTF-8

Maximum value length - 256 Unicode characters in UTF-8

If your tagging schema is used across multiple services and resources, remember that other services may have restrictions on allowed characters. Generally allowed characters are: letters, numbers, and spaces representable in UTF-8, and the following characters: + - = . _ : / @.

Tag keys and values are case-sensitive.

Do not use aws: , AWS: , or any upper or lowercase combination of such as a prefix for either keys or values as it is reserved for Amazon Web Services use. You cannot edit or delete tag keys or values with this prefix. Tags with this prefix do not count against your tags per resource limit.

--task-definition (string)

The family and revision (family:revision ) or full ARN of the task definition to run. If a revision isn’t specified, the latest ACTIVE revision is used.

The full ARN value must match the value that you specified as the Resource of the principal’s permissions policy.

When you specify a task definition, you must either specify a specific revision, or all revisions in the ARN.

To specify a specific revision, include the revision number in the ARN. For example, to specify revision 2, use arn:aws:ecs:us-east-1:111122223333:task-definition/TaskFamilyName:2 .

To specify all revisions, use the wildcard (*) in the ARN. For example, to specify all revisions, use arn:aws:ecs:us-east-1:111122223333:task-definition/TaskFamilyName:* .

For more information, see Policy Resources for Amazon ECS in the Amazon Elastic Container Service Developer Guide.

--client-token (string)

encrypted -> (boolean)

Indicates whether the volume should be encrypted. If no value is specified, encryption is turned on by default. This parameter maps 1:1 with the Encrypted parameter of the CreateVolume API in the Amazon EC2 API Reference .

kmsKeyId -> (string)

The Amazon Resource Name (ARN) identifier of the Amazon Web Services Key Management Service key to use for Amazon EBS encryption. When encryption is turned on and no Amazon Web Services Key Management Service key is specified, the default Amazon Web Services managed key for Amazon EBS volumes is used. This parameter maps 1:1 with the KmsKeyId parameter of the CreateVolume API in the Amazon EC2 API Reference .

Warning
Amazon Web Services authenticates the Amazon Web Services Key Management Service key asynchronously. Therefore, if you specify an ID, alias, or ARN that is invalid, the action can appear to complete, but eventually fails.

volumeType -> (string)

The volume type. This parameter maps 1:1 with the VolumeType parameter of the CreateVolume API in the Amazon EC2 API Reference . For more information, see Amazon EBS volume types in the Amazon EC2 User Guide .

The following are the supported volume types.

General Purpose SSD: gp2 |gp3

Provisioned IOPS SSD: io1 |io2

Throughput Optimized HDD: st1

Cold HDD: sc1

Magnetic: standard

Note
The magnetic volume type is not supported on Fargate.

sizeInGiB -> (integer)

The size of the volume in GiB. You must specify either a volume size or a snapshot ID. If you specify a snapshot ID, the snapshot size is used for the volume size by default. You can optionally specify a volume size greater than or equal to the snapshot size. This parameter maps 1:1 with the Size parameter of the CreateVolume API in the Amazon EC2 API Reference .

The following are the supported volume size values for each volume type.

gp2 and gp3 : 1-16,384

iops -> (integer)

The number of I/O operations per second (IOPS). For gp3 , io1 , and io2 volumes, this represents the number of IOPS that are provisioned for the volume. For gp2 volumes, this represents the baseline performance of the volume and the rate at which the volume accumulates I/O credits for bursting.

The following are the supported values for each volume type.

gp3 : 3,000 - 16,000 IOPS

io1 : 100 - 64,000 IOPS

io2 : 100 - 256,000 IOPS

This parameter is required for io1 and io2 volume types. The default for gp3 volumes is 3,000 IOPS . This parameter is not supported for st1 , sc1 , or standard volume types.

This parameter maps 1:1 with the Iops parameter of the CreateVolume API in the Amazon EC2 API Reference .

throughput -> (integer)

The throughput to provision for a volume, in MiB/s, with a maximum of 1,000 MiB/s. This parameter maps 1:1 with the Throughput parameter of the CreateVolume API in the Amazon EC2 API Reference .

The termination policy for the volume when the task exits. This provides a way to control whether Amazon ECS terminates the Amazon EBS volume when the task stops.

deleteOnTermination -> (boolean)

Indicates whether the volume should be deleted on when the task stops. If a value of true is specified, Amazon ECS deletes the Amazon EBS volume on your behalf when the task goes into the STOPPED state. If no value is specified, the default value is true is used. When set to false , Amazon ECS leaves the volume in your account.

filesystemType -> (string)

The Linux filesystem type for the volume. For volumes created from a snapshot, you must specify the same filesystem type that the volume was using when the snapshot was created. If there is a filesystem type mismatch, the task will fail to start.

The available filesystem types are ext3 , ext4 , and xfs . If no value is specified, the xfs filesystem type is used by default.

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command. The generated JSON skeleton is not stable between versions of the AWS CLI and there are no backwards compatibility guarantees in the JSON skeleton generated.

Global Options¶

--debug (boolean)

Turn on debug logging.

--endpoint-url (string)

Override command’s default URL with the given URL.

--no-verify-ssl (boolean)

By default, the AWS CLI uses SSL when communicating with AWS services. For each SSL connection, the AWS CLI will verify SSL certificates. This option overrides the default behavior of verifying SSL certificates.

--no-paginate (boolean)

Disable automatic pagination. If automatic pagination is disabled, the AWS CLI will only make one call, for the first page of results.

--output (string)

The formatting style for command output.

json
text
table
yaml
yaml-stream

--query (string)

A JMESPath query to use in filtering the response data.

--profile (string)

Use a specific profile from your credential file.

--region (string)

The region to use. Overrides config/env settings.

--version (string)

Display the version of this tool.

--color (string)

Turn on/off color output.

on
off
auto

--no-sign-request (boolean)

Do not sign requests. Credentials will not be loaded if this argument is provided.

--ca-bundle (string)

The CA certificate bundle to use when verifying SSL certificates. Overrides config/env settings.

--cli-read-timeout (int)

The maximum socket read time in seconds. If the value is set to 0, the socket read will be blocking and not timeout. The default value is 60 seconds.

--cli-connect-timeout (int)

The maximum socket connect time in seconds. If the value is set to 0, the socket connect will be blocking and not timeout. The default value is 60 seconds.

--cli-binary-format (string)

The formatting style to be used for binary blobs. The default format is base64. The base64 format expects binary blobs to be provided as a base64 encoded string. The raw-in-base64-out format preserves compatibility with AWS CLI V1 behavior and binary values must be passed literally. When providing contents from a file that map to a binary blob fileb:// will always be treated as binary and use the file contents directly regardless of the cli-binary-format setting. When using file:// the file contents will need to properly formatted for the configured cli-binary-format.

base64
raw-in-base64-out

--no-cli-pager (boolean)

Disable cli pager for output.

--cli-auto-prompt (boolean)

Automatically prompt for CLI input parameters.

--no-cli-auto-prompt (boolean)

Disable automatically prompt for CLI input parameters.

Examples¶

Note

To use the following examples, you must have the AWS CLI installed and configured. See the Getting started guide in the AWS CLI User Guide for more information.

Unless otherwise stated, all examples have unix-like quotation rules. These examples will need to be adapted to your terminal’s quoting rules. See Using quotation marks with strings in the AWS CLI User Guide .

To run a task on your default cluster

The following run-task example runs a task on the default cluster and uses a client token.

aws ecs run-task \
    --cluster default \
    --task-definition sleep360:1 \
    --client-token 550e8400-e29b-41d4-a716-446655440000

This parameter is available for both the EC2 and Fargate launch types.

This parameter is available for both the Linux and Windows operating systems.

The container instance must have at least version 1.67.0 of the container agent and at least version 1.67.0-1 of the ecs-init package

You can specify a maximum of 100 port ranges per container.

You do not specify a hostPortRange . The value of the hostPortRange is set as follows:

For containers in a task with the awsvpc network mode, the hostPortRange is set to the same value as the containerPortRange . This is a static mapping strategy.

For containers in a task with the bridge network mode, the Amazon ECS agent finds open host ports from the default ephemeral range and passes it to docker to bind them to the container ports.

The containerPortRange valid values are between 1 and 65535.

A port can only be included in one port mapping per container.

You cannot specify overlapping port ranges.

The first port in the range must be less than last port in the range.

Docker recommends that you turn off the docker-proxy in the Docker daemon config file when you have a large number of ports. For more information, see Issue #11185 on the Github website. For information about how to turn off the docker-proxy in the Docker daemon config file, see Docker daemon in the Amazon ECS Developer Guide .

You can call ` DescribeTasks https://docs.aws.amazon.com/AmazonECS/latest/APIReference/API_DescribeTasks.html`__ to view the hostPortRange which are the host ports that are bound to the container ports.

The platform version where your task runs on. A platform version is only specified for tasks that use the Fargate launch type. If you didn’t specify one, the LATEST platform version is used. For more information, see Fargate Platform Versions in the Amazon Elastic Container Service Developer Guide .

platformFamily -> (string)

The operating system that your tasks are running on. A platform family is specified only for tasks that use the Fargate launch type.

All tasks that run as part of this service must use the same platformFamily value as the service (for example, LINUX. ).

pullStartedAt -> (timestamp)

The Unix timestamp for the time when the container image pull began.

pullStoppedAt -> (timestamp)

The Unix timestamp for the time when the container image pull completed.

startedAt -> (timestamp)

The Unix timestamp for the time when the task started. More specifically, it’s for the time when the task transitioned from the PENDING state to the RUNNING state.

startedBy -> (string)

The tag specified when a task is started. If an Amazon ECS service started the task, the startedBy parameter contains the deployment ID of that service.

stopCode -> (string)

The stop code indicating why a task was stopped. The stoppedReason might contain additional details.

For more information about stop code, see Stopped tasks error codes in the Amazon ECS Developer Guide .

stoppedAt -> (timestamp)

The Unix timestamp for the time when the task was stopped. More specifically, it’s for the time when the task transitioned from the RUNNING state to the STOPPED state.

stoppedReason -> (string)

The reason that the task was stopped.

stoppingAt -> (timestamp)

The Unix timestamp for the time when the task stops. More specifically, it’s for the time when the task transitions from the RUNNING state to STOPPING .

tags -> (list)

The metadata that you apply to the task to help you categorize and organize the task. Each tag consists of a key and an optional value. You define both the key and value.

The following basic restrictions apply to tags:

Maximum number of tags per resource - 50

For each resource, each tag key must be unique, and each tag key can have only one value.

Maximum key length - 128 Unicode characters in UTF-8

Maximum value length - 256 Unicode characters in UTF-8

If your tagging schema is used across multiple services and resources, remember that other services may have restrictions on allowed characters. Generally allowed characters are: letters, numbers, and spaces representable in UTF-8, and the following characters: + - = . _ : / @.

Tag keys and values are case-sensitive.

Do not use aws: , AWS: , or any upper or lowercase combination of such as a prefix for either keys or values as it is reserved for Amazon Web Services use. You cannot edit or delete tag keys or values with this prefix. Tags with this prefix do not count against your tags per resource limit.

key -> (string)

One part of a key-value pair that make up a tag. A key is a general label that acts like a category for more specific tag values.

value -> (string)

The optional part of a key-value pair that make up a tag. A value acts as a descriptor within a tag category (key).

taskArn -> (string)

The Amazon Resource Name (ARN) of the task.

taskDefinitionArn -> (string)

The ARN of the task definition that creates the task.

version -> (long)

The version counter for the task. Every time a task experiences a change that starts a CloudWatch event, the version counter is incremented. If you replicate your Amazon ECS task state with CloudWatch Events, you can compare the version of a task reported by the Amazon ECS API actions with the version reported in CloudWatch Events for the task (inside the detail object) to verify that the version in your event stream is current.

ephemeralStorage -> (structure)

The ephemeral storage settings for the task.

sizeInGiB -> (integer)

The total amount, in GiB, of ephemeral storage to set for the task. The minimum supported value is 20 GiB and the maximum supported value is 200 GiB.

fargateEphemeralStorage -> (structure)

The Fargate ephemeral storage settings for the task.

sizeInGiB -> (integer)

The total amount, in GiB, of the ephemeral storage to set for the task. The minimum supported value is 20 GiB and the maximum supported value is 200 GiB.

kmsKeyId -> (string)

Specify an Key Management Service key ID to encrypt the ephemeral storage for the task.

failures -> (list)

Any failures associated with the call.

For information about how to address failures, see Service event messages and API failure reasons in the Amazon Elastic Container Service Developer Guide .

(structure)

A failed resource. For a list of common causes, see API failure reasons in the Amazon Elastic Container Service Developer Guide .

arn -> (string)

The Amazon Resource Name (ARN) of the failed resource.

reason -> (string)

The reason for the failure.

detail -> (string)

The details of the failure.
