TaskSet

Information about a set of Amazon ECS tasks in either an AWS CodeDeploy or an EXTERNAL deployment. An Amazon ECS task set includes details such as the desired number of tasks, how many tasks are running, and whether the task set serves production traffic.

capacityProviderStrategy

The capacity provider strategy that are associated with the task set.

Type: Array of CapacityProviderStrategyItem objects

Required: No

clusterArn

The Amazon Resource Name (ARN) of the cluster that the service that hosts the task set exists in.

Type: String

Required: No

computedDesiredCount

The computed desired count for the task set. This is calculated by multiplying the service's desiredCount by the task set's scale percentage. The result is always rounded up. For example, if the computed desired count is 1.2, it rounds up to 2 tasks.

Type: Integer

Required: No

createdAt

The Unix timestamp for the time when the task set was created.

Type: Timestamp

Required: No

externalId

The external ID associated with the task set.

If an AWS CodeDeploy deployment created a task set, the externalId parameter contains the AWS CodeDeploy deployment ID.

If a task set is created for an external deployment and is associated with a service discovery registry, the externalId parameter contains the ECS_TASK_SET_EXTERNAL_ID AWS Cloud Map attribute.

Type: String

Required: No

id

The ID of the task set.

Type: String

Required: No

launchType

The launch type the tasks in the task set are using. For more information, see Amazon ECS launch types in the Amazon Elastic Container Service Developer Guide.

Type: String

Valid Values: EC2 | FARGATE | EXTERNAL

Required: No

loadBalancers

Details on a load balancer that are used with a task set.

Type: Array of LoadBalancer objects

Required: No

networkConfiguration

The network configuration for the task set.

Type: NetworkConfiguration object

Required: No

pendingCount

The number of tasks in the task set that are in the PENDING status during a deployment. A task in the PENDING state is preparing to enter the RUNNING state. A task set enters the PENDING status when it launches for the first time or when it's restarted after being in the STOPPED state.

Type: Integer

Required: No

platformFamily

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

All tasks in the set must have the same value.

Type: String

Required: No

platformVersion

The AWS Fargate platform version where the tasks in the task set are running. A platform version is only specified for tasks run on AWS Fargate. For more information, see AWS Fargate platform versions in the Amazon Elastic Container Service Developer Guide.

Type: String

Required: No

runningCount

The number of tasks in the task set that are in the RUNNING status during a deployment. A task in the RUNNING state is running and ready for use.

Type: Integer

Required: No

scale

A floating-point percentage of your desired number of tasks to place and keep running in the task set.

Type: Scale object

Required: No

serviceArn

The Amazon Resource Name (ARN) of the service the task set exists in.

Type: String

Required: No

serviceRegistries

The details for the service discovery registries to assign to this task set. For more information, see Service discovery.

Type: Array of ServiceRegistry objects

Required: No

stabilityStatus

The stability status. This indicates whether the task set has reached a steady state. If the following conditions are met, the task set are in STEADY_STATE:

The task runningCount is equal to the computedDesiredCount.
The pendingCount is 0.
There are no tasks that are running on container instances in the DRAINING status.
All tasks are reporting a healthy status from the load balancers, service discovery, and container health checks.

If any of those conditions aren't met, the stability status returns STABILIZING.

Type: String

Valid Values: STEADY_STATE | STABILIZING

Required: No

stabilityStatusAt

The Unix timestamp for the time when the task set stability status was retrieved.

Type: Timestamp

Required: No

startedBy

The tag specified when a task set is started. If an AWS CodeDeploy deployment created the task set, the startedBy parameter is CODE_DEPLOY. If an external deployment created the task set, the startedBy field isn't used.

Type: String

Required: No

status

The status of the task set. The following describes each state.

PRIMARY: The task set is serving production traffic.
ACTIVE: The task set isn't serving production traffic.
DRAINING: The tasks in the task set are being stopped, and their corresponding targets are being deregistered from their target group.

Type: String

Required: No

tags

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

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 AWS 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.

Type: Array of Tag objects

Array Members: Minimum number of 0 items. Maximum number of 50 items.

Required: No

taskDefinition

The task definition that the task set is using.

Type: String

Required: No

taskSetArn

The Amazon Resource Name (ARN) of the task set.

Type: String

Required: No

updatedAt

The Unix timestamp for the time when the task set was last updated.

Type: Timestamp

Required: No
