AWSSDK.ECS

Amazon EC2 Container Service (Amazon ECS) is a highly scalable, fast, container management service that makes it easy to run, stop, and manage Docker containers on a cluster of EC2 instances. Amazon ECS lets you launch and stop container-enabled applications with simple API calls, allows you to get the state of your cluster from a centralized service, and gives you access to many familiar Amazon EC2 features like security groups, Amazon EBS volumes, and IAM roles.

You can use Amazon ECS to schedule the placement of containers across your cluster based on your resource needs, isolation policies, and availability requirements. Amazon EC2 Container Service eliminates the need for you to operate your own cluster management and configuration management systems or worry about scaling your management infrastructure.

CreateCluster Operation

Creates a new Amazon ECS cluster. By default, your account receives a default cluster when you launch your first container instance. However, you can create your own cluster with a unique name with the CreateCluster action.

Arguments

clusterName = ::String

The name of your cluster. If you do not specify a name for your cluster, you create a cluster named default. Up to 255 letters (uppercase and lowercase), numbers, hyphens, and underscores are allowed.

Returns

CreateClusterResponse

Exceptions

ServerException, ClientException or InvalidParameterException.

Example: To create a new cluster

This example creates a cluster in your default region.

Input:

[
    "clusterName" => "my_cluster"
]

Output:

Dict(
    "cluster" => Dict(
        "activeServicesCount" => 0,
        "clusterArn" => "arn:aws:ecs:us-east-1:012345678910:cluster/my_cluster",

CreateService Operation

Runs and maintains a desired number of tasks from a specified task definition. If the number of tasks running in a service drops below desiredCount, Amazon ECS spawns another copy of the task in the specified cluster. To update an existing service, see UpdateService.

In addition to maintaining the desired count of tasks in your service, you can optionally run your service behind a load balancer. The load balancer distributes traffic across the tasks that are associated with the service. For more information, see Service Load Balancing in the Amazon EC2 Container Service Developer Guide.

You can optionally specify a deployment configuration for your service. During a deployment (which is triggered by changing the task definition or the desired count of a service with an UpdateService operation), the service scheduler uses the minimumHealthyPercent and maximumPercent parameters to determine the deployment strategy.

The minimumHealthyPercent represents a lower limit on the number of your service's tasks that must remain in the RUNNING state during a deployment, as a percentage of the desiredCount (rounded up to the nearest integer). This parameter enables you to deploy without using additional cluster capacity. For example, if your service has a desiredCount of four tasks and a minimumHealthyPercent of 50%, the scheduler can stop two existing tasks to free up cluster capacity before starting two new tasks. Tasks for services that do not use a load balancer are considered healthy if they are in the RUNNING state. Tasks for services that do use a load balancer are considered healthy if they are in the RUNNING state and the container instance they are hosted on is reported as healthy by the load balancer. The default value for minimumHealthyPercent is 50% in the console and 100% for the AWS CLI, the AWS SDKs, and the APIs.

The maximumPercent parameter represents an upper limit on the number of your service's tasks that are allowed in the RUNNING or PENDING state during a deployment, as a percentage of the desiredCount (rounded down to the nearest integer). This parameter enables you to define the deployment batch size. For example, if your service has a desiredCount of four tasks and a maximumPercent value of 200%, the scheduler can start four new tasks before stopping the four older tasks (provided that the cluster resources required to do this are available). The default value for maximumPercent is 200%.

When the service scheduler launches new tasks, it determines task placement in your cluster using the following logic:

  • Determine which of the container instances in your cluster can support your service's task definition (for example, they have the required CPU, memory, ports, and container instance attributes).

  • By default, the service scheduler attempts to balance tasks across Availability Zones in this manner (although you can choose a different placement strategy) with the placementStrategy parameter):

    • Sort the valid container instances by the fewest number of running tasks for this service in the same Availability Zone as the instance. For example, if zone A has one running service task and zones B and C each have zero, valid container instances in either zone B or C are considered optimal for placement.

    • Place the new service task on a valid container instance in an optimal Availability Zone (based on the previous steps), favoring container instances with the fewest number of running tasks for this service.

Arguments

cluster = ::String

The short name or full Amazon Resource Name (ARN) of the cluster on which to run your service. If you do not specify a cluster, the default cluster is assumed.

serviceName = ::StringRequired

The name of your service. Up to 255 letters (uppercase and lowercase), numbers, hyphens, and underscores are allowed. Service names must be unique within a cluster, but you can have similarly named services in multiple clusters within a region or across multiple regions.

taskDefinition = ::StringRequired

The family and revision (family:revision) or full Amazon Resource Name (ARN) of the task definition to run in your service. If a revision is not specified, the latest ACTIVE revision is used.

loadBalancers = [[ ... ], ...]

A load balancer object representing the load balancer to use with your service. Currently, you are limited to one load balancer or target group per service. After you create a service, the load balancer name or target group ARN, container name, and container port specified in the service definition are immutable.

For Classic Load Balancers, this object must contain the load balancer name, the container name (as it appears in a container definition), and the container port to access from the load balancer. When a task from this service is placed on a container instance, the container instance is registered with the load balancer specified here.

For Application Load Balancers and Network Load Balancers, this object must contain the load balancer target group ARN, the container name (as it appears in a container definition), and the container port to access from the load balancer. When a task from this service is placed on a container instance, the container instance and port combination is registered as a target in the target group specified here.

 loadBalancers = [[
        "targetGroupArn" =>  ::String,
        "loadBalancerName" =>  ::String,
        "containerName" =>  ::String,
        "containerPort" =>  ::Int
    ], ...]

desiredCount = ::IntRequired

The number of instantiations of the specified task definition to place and keep running on your cluster.

clientToken = ::String

Unique, case-sensitive identifier you provide to ensure the idempotency of the request. Up to 32 ASCII characters are allowed.

role = ::String

The name or full Amazon Resource Name (ARN) of the IAM role that allows Amazon ECS to make calls to your load balancer on your behalf. This parameter is required if you are using a load balancer with your service. If you specify the role parameter, you must also specify a load balancer object with the loadBalancers parameter.

If your specified role has a path other than /, then you must either specify the full role ARN (this is recommended) or prefix the role name with the path. For example, if a role with the name bar has a path of /foo/ then you would specify /foo/bar as the role name. For more information, see Friendly Names and Paths in the IAM User Guide.

deploymentConfiguration = [ ... ]

Optional deployment parameters that control how many tasks run during the deployment and the ordering of stopping and starting tasks.

 deploymentConfiguration = [
        "maximumPercent" =>  ::Int,
        "minimumHealthyPercent" =>  ::Int
    ]

placementConstraints = [[ ... ], ...]

An array of placement constraint objects to use for tasks in your service. You can specify a maximum of 10 constraints per task (this limit includes constraints in the task definition and those specified at run time).

 placementConstraints = [[
        "type" =>  "distinctInstance" or "memberOf",
        "expression" =>  ::String
    ], ...]

placementStrategy = [[ ... ], ...]

The placement strategy objects to use for tasks in your service. You can specify a maximum of 5 strategy rules per service.

 placementStrategy = [[
        "type" =>  "random", "spread" or "binpack",
        "field" =>  ::String
    ], ...]

Returns

CreateServiceResponse

Exceptions

ServerException, ClientException, InvalidParameterException or ClusterNotFoundException.

Example: To create a new service

This example creates a service in your default region called $ecs-simple-service$. The service uses the $hello_world$ task definition and it maintains 10 copies of that task.

DeleteCluster Operation

Deletes the specified cluster. You must deregister all container instances from this cluster before you may delete it. You can list the container instances in a cluster with ListContainerInstances and deregister them with DeregisterContainerInstance.

Arguments

cluster = ::StringRequired

The short name or full Amazon Resource Name (ARN) of the cluster to delete.

Returns

DeleteService Operation

Deletes a specified service within a cluster. You can delete a service if you have no running tasks in it and the desired task count is zero. If the service is actively maintaining tasks, you cannot delete it, and you must update the service to a desired task count of zero. For more information, see UpdateService.

Note

When you delete a service, if there are still running tasks that require cleanup, the service status moves from ACTIVE to DRAINING, and the service is no longer visible in the console or in ListServices API operations. After the tasks have stopped, then the service status moves from DRAINING to INACTIVE. Services in the DRAINING or INACTIVE status can still be viewed with DescribeServices API operations; however, in the future, INACTIVE services may be cleaned up and purged from Amazon ECS record keeping, and DescribeServices API operations on those services will return a ServiceNotFoundException error.

Arguments

cluster = ::String

The short name or full Amazon Resource Name (ARN) of the cluster that hosts the service to delete. If you do not specify a cluster, the default cluster is assumed.

service = ::StringRequired

The name of the service to delete.

Returns

DeleteServiceResponse

Exceptions

ServerException, ClientException, InvalidParameterException, ClusterNotFoundException or ServiceNotFoundException.

Example: To delete a service

This example deletes the my-http-service service. The service must have a desired count and running count of 0 before you can delete it.

using AWSCore.Services.ecs
ecs([::AWSConfig], "DeregisterContainerInstance", arguments::Dict)
ecs([::AWSConfig], "DeregisterContainerInstance", containerInstance=, <keyword arguments>)

DeregisterContainerInstance Operation

Deregisters an Amazon ECS container instance from the specified cluster. This instance is no longer available to run tasks.

If you intend to use the container instance for some other purpose after deregistration, you should stop all of the tasks running on the container instance before deregistration to avoid any orphaned tasks from consuming resources.

Deregistering a container instance removes the instance from a cluster, but it does not terminate the EC2 instance; if you are finished using the instance, be sure to terminate it in the Amazon EC2 console to stop billing.

Note

If you terminate a running container instance, Amazon ECS automatically deregisters the instance from your cluster (stopped container instances or instances with disconnected agents are not automatically deregistered when terminated).

Arguments

cluster = ::String

The short name or full Amazon Resource Name (ARN) of the cluster that hosts the container instance to deregister. If you do not specify a cluster, the default cluster is assumed.

containerInstance = ::StringRequired

The container instance ID or full Amazon Resource Name (ARN) of the container instance to deregister. The ARN contains the arn:aws:ecs namespace, followed by the region of the container instance, the AWS account ID of the container instance owner, the container-instance namespace, and then the container instance ID. For example, arn:aws:ecs:*region*:*aws_account_id*:container-instance/*container_instance_ID* .

force = ::Bool

Forces the deregistration of the container instance. If you have tasks running on the container instance when you deregister it with the force option, these tasks remain running until you terminate the instance or the tasks stop through some other means, but they are orphaned (no longer monitored or accounted for by Amazon ECS). If an orphaned task on your container instance is part of an Amazon ECS service, then the service scheduler starts another copy of that task, on a different container instance if possible.

Any containers in orphaned service tasks that are registered with a Classic Load Balancer or an Application Load Balancer target group are deregistered, and they will begin connection draining according to the settings on the load balancer or target group.

Returns

DeregisterContainerInstanceResponse

Exceptions

ServerException, ClientException, InvalidParameterException or ClusterNotFoundException.

Example: To deregister a container instance from a cluster

This example deregisters a container instance from the specified cluster in your default region. If there are still tasks running on the container instance, you must either stop those tasks before deregistering, or use the force option.

Input:

[
    "cluster" => "default",
    "containerInstance" => "container_instance_UUID",
    "force" => true
]

Output:

Dict(

using AWSCore.Services.ecs
ecs([::AWSConfig], "DeregisterTaskDefinition", arguments::Dict)
ecs([::AWSConfig], "DeregisterTaskDefinition", taskDefinition=)

DeregisterTaskDefinition Operation

Deregisters the specified task definition by family and revision. Upon deregistration, the task definition is marked as INACTIVE. Existing tasks and services that reference an INACTIVE task definition continue to run without disruption. Existing services that reference an INACTIVE task definition can still scale up or down by modifying the service's desired count.

You cannot use an INACTIVE task definition to run new tasks or create new services, and you cannot update an existing service to reference an INACTIVE task definition (although there may be up to a 10 minute window following deregistration where these restrictions have not yet taken effect).

Note

At this time, INACTIVE task definitions remain discoverable in your account indefinitely; however, this behavior is subject to change in the future, so you should not rely on INACTIVE task definitions persisting beyond the life cycle of any associated tasks and services.

Arguments

taskDefinition = ::StringRequired

The family and revision (family:revision) or full Amazon Resource Name (ARN) of the task definition to deregister. You must specify a revision.

Returns

DeregisterTaskDefinitionResponse

Exceptions

ServerException, ClientException or InvalidParameterException.

using AWSCore.Services.ecs
ecs([::AWSConfig], "ListAttributes", arguments::Dict)
ecs([::AWSConfig], "ListAttributes", targetType=, <keyword arguments>)

ListAttributes Operation

Lists the attributes for Amazon ECS resources within a specified target type and cluster. When you specify a target type and cluster, ListAttributes returns a list of attribute objects, one for each attribute on each resource. You can filter the list of results to a single attribute name to only return results that have that name. You can also filter the results by attribute name and value, for example, to see which container instances in a cluster are running a Linux AMI (ecs.os-type=linux).

Arguments

cluster = ::String

The short name or full Amazon Resource Name (ARN) of the cluster to list attributes. If you do not specify a cluster, the default cluster is assumed.

targetType = "container-instance"Required

The type of the target with which to list attributes.

attributeName = ::String

The name of the attribute with which to filter the results.

attributeValue = ::String

The value of the attribute with which to filter results. You must also specify an attribute name to use this parameter.

nextToken = ::String

The nextToken value returned from a previous paginated ListAttributes request where maxResults was used and the results exceeded the value of that parameter. Pagination continues from the end of the previous results that returned the nextToken value. This value is null when there are no more results to return.

Note

This token should be treated as an opaque identifier that is only used to retrieve the next items in a list and not for other programmatic purposes.

maxResults = ::Int

The maximum number of cluster results returned by ListAttributes in paginated output. When this parameter is used, ListAttributes only returns maxResults results in a single page along with a nextToken response element. The remaining results of the initial request can be seen by sending another ListAttributes request with the returned nextToken value. This value can be between 1 and 100. If this parameter is not used, then ListAttributes returns up to 100 results and a nextToken value if applicable.

Returns

ListAttributesResponse

Exceptions

ClusterNotFoundException or InvalidParameterException.

ListClusters Operation

Returns a list of existing clusters.

Arguments

nextToken = ::String

The nextToken value returned from a previous paginated ListClusters request where maxResults was used and the results exceeded the value of that parameter. Pagination continues from the end of the previous results that returned the nextToken value. This value is null when there are no more results to return.

Note

This token should be treated as an opaque identifier that is only used to retrieve the next items in a list and not for other programmatic purposes.

maxResults = ::Int

The maximum number of cluster results returned by ListClusters in paginated output. When this parameter is used, ListClusters only returns maxResults results in a single page along with a nextToken response element. The remaining results of the initial request can be seen by sending another ListClusters request with the returned nextToken value. This value can be between 1 and 100. If this parameter is not used, then ListClusters returns up to 100 results and a nextToken value if applicable.

Returns

If this parameter is not used, then ListContainerInstances returns up to 100 results and a nextToken value if applicable.

status = "ACTIVE" or "DRAINING"

Filters the container instances by status. For example, if you specify the DRAINING status, the results include only container instances that have been set to DRAINING using UpdateContainerInstancesState. If you do not specify this parameter, the default is to include container instances set to ACTIVE and DRAINING.

Returns

This token should be treated as an opaque identifier that is only used to retrieve the next items in a list and not for other programmatic purposes.

maxResults = ::Int

The maximum number of service results returned by ListServices in paginated output. When this parameter is used, ListServices only returns maxResults results in a single page along with a nextToken response element. The remaining results of the initial request can be seen by sending another ListServices request with the returned nextToken value. This value can be between 1 and 10. If this parameter is not used, then ListServices returns up to 10 results and a nextToken value if applicable.

Returns

ListServicesResponse

Exceptions

ServerException, ClientException, InvalidParameterException or ClusterNotFoundException.

Example: To list the services in a cluster

This example lists the services running in the default cluster for an account.

ListTaskDefinitionFamilies Operation

Returns a list of task definition families that are registered to your account (which may include task definition families that no longer have any ACTIVE task definition revisions).

You can filter out task definition families that do not contain any ACTIVE task definition revisions by setting the status parameter to ACTIVE. You can also filter the results with the familyPrefix parameter.

Arguments

familyPrefix = ::String

The familyPrefix is a string that is used to filter the results of ListTaskDefinitionFamilies. If you specify a familyPrefix, only task definition family names that begin with the familyPrefix string are returned.

status = "ACTIVE", "INACTIVE" or "ALL"

The task definition family status with which to filter the ListTaskDefinitionFamilies results. By default, both ACTIVE and INACTIVE task definition families are listed. If this parameter is set to ACTIVE, only task definition families that have an ACTIVE task definition revision are returned. If this parameter is set to INACTIVE, only task definition families that do not have any ACTIVE task definition revisions are returned. If you paginate the resulting output, be sure to keep the status value constant in each subsequent request.

nextToken = ::String

The nextToken value returned from a previous paginated ListTaskDefinitionFamilies request where maxResults was used and the results exceeded the value of that parameter. Pagination continues from the end of the previous results that returned the nextToken value. This value is null when there are no more results to return.

Note

This token should be treated as an opaque identifier that is only used to retrieve the next items in a list and not for other programmatic purposes.

maxResults = ::Int

The maximum number of task definition family results returned by ListTaskDefinitionFamilies in paginated output. When this parameter is used, ListTaskDefinitions only returns maxResults results in a single page along with a nextToken response element. The remaining results of the initial request can be seen by sending another ListTaskDefinitionFamilies request with the returned nextToken value. This value can be between 1 and 100. If this parameter is not used, then ListTaskDefinitionFamilies returns up to 100 results and a nextToken value if applicable.

Returns

ListTaskDefinitionFamiliesResponse

Exceptions

ServerException, ClientException or InvalidParameterException.

Example: To list your registered task definition families

This example lists all of your registered task definition families.

Input:

ListTaskDefinitions Operation

Returns a list of task definitions that are registered to your account. You can filter the results by family name with the familyPrefix parameter or by status with the status parameter.

Arguments

familyPrefix = ::String

The full family name with which to filter the ListTaskDefinitions results. Specifying a familyPrefix limits the listed task definitions to task definition revisions that belong to that family.

status = "ACTIVE" or "INACTIVE"

The task definition status with which to filter the ListTaskDefinitions results. By default, only ACTIVE task definitions are listed. By setting this parameter to INACTIVE, you can view task definitions that are INACTIVE as long as an active task or service still references them. If you paginate the resulting output, be sure to keep the status value constant in each subsequent request.

sort = "ASC" or "DESC"

The order in which to sort the results. Valid values are ASC and DESC. By default (ASC), task definitions are listed lexicographically by family name and in ascending numerical order by revision so that the newest task definitions in a family are listed last. Setting this parameter to DESC reverses the sort order on family name and revision so that the newest task definitions in a family are listed first.

nextToken = ::String

The nextToken value returned from a previous paginated ListTaskDefinitions request where maxResults was used and the results exceeded the value of that parameter. Pagination continues from the end of the previous results that returned the nextToken value. This value is null when there are no more results to return.

Note

This token should be treated as an opaque identifier that is only used to retrieve the next items in a list and not for other programmatic purposes.

maxResults = ::Int

The maximum number of task definition results returned by ListTaskDefinitions in paginated output. When this parameter is used, ListTaskDefinitions only returns maxResults results in a single page along with a nextToken response element. The remaining results of the initial request can be seen by sending another ListTaskDefinitions request with the returned nextToken value. This value can be between 1 and 100. If this parameter is not used, then ListTaskDefinitions returns up to 100 results and a nextToken value if applicable.

Returns

ListTasks Operation

Returns a list of tasks for a specified cluster. You can filter the results by family name, by a particular container instance, or by the desired status of the task with the family, containerInstance, and desiredStatus parameters.

Recently-stopped tasks might appear in the returned results. Currently, stopped tasks appear in the returned results for at least one hour.

Arguments

cluster = ::String

The short name or full Amazon Resource Name (ARN) of the cluster that hosts the tasks to list. If you do not specify a cluster, the default cluster is assumed.

containerInstance = ::String

The container instance ID or full Amazon Resource Name (ARN) of the container instance with which to filter the ListTasks results. Specifying a containerInstance limits the results to tasks that belong to that container instance.

family = ::String

The name of the family with which to filter the ListTasks results. Specifying a family limits the results to tasks that belong to that family.

nextToken = ::String

The nextToken value returned from a previous paginated ListTasks request where maxResults was used and the results exceeded the value of that parameter. Pagination continues from the end of the previous results that returned the nextToken value. This value is null when there are no more results to return.

Note

This token should be treated as an opaque identifier that is only used to retrieve the next items in a list and not for other programmatic purposes.

maxResults = ::Int

The maximum number of task results returned by ListTasks in paginated output. When this parameter is used, ListTasks only returns maxResults results in a single page along with a nextToken response element. The remaining results of the initial request can be seen by sending another ListTasks request with the returned nextToken value. This value can be between 1 and 100. If this parameter is not used, then ListTasks returns up to 100 results and a nextToken value if applicable.

startedBy = ::String

The startedBy value with which to filter the task results. Specifying a startedBy value limits the results to tasks that were started with that value.

serviceName = ::String

The name of the service with which to filter the ListTasks results. Specifying a serviceName limits the results to tasks that belong to that service.

desiredStatus = "RUNNING", "PENDING" or "STOPPED"

The task desired status with which to filter the ListTasks results. Specifying a desiredStatus of STOPPED limits the results to tasks that ECS has set the desired status to STOPPED, which can be useful for debugging tasks that are not starting properly or have died or finished. The default status filter is RUNNING, which shows tasks that ECS has set the desired status to RUNNING.

Note

Although you can filter results based on a desired status of PENDING, this will not return any results because ECS never sets the desired status of a task to that value (only a task's lastStatus may have a value of PENDING).

Returns

ListTasksResponse

Exceptions

ServerException, ClientException, InvalidParameterException, ClusterNotFoundException or ServiceNotFoundException.

Example: To list the tasks in a cluster

This example lists all of the tasks in a cluster.

Input:

[
    "cluster" => "default"
]

Output:

RegisterTaskDefinition Operation

Registers a new task definition from the supplied family and containerDefinitions. Optionally, you can add data volumes to your containers with the volumes parameter. For more information about task definition parameters and defaults, see Amazon ECS Task Definitions in the Amazon EC2 Container Service Developer Guide.

You can specify an IAM role for your task with the taskRoleArn parameter. When you specify an IAM role for a task, its containers can then use the latest versions of the AWS CLI or SDKs to make API requests to the AWS services that are specified in the IAM policy associated with the role. For more information, see IAM Roles for Tasks in the Amazon EC2 Container Service Developer Guide.

You can specify a Docker networking mode for the containers in your task definition with the networkMode parameter. The available network modes correspond to those described in Network settings in the Docker run reference.

Arguments

family = ::StringRequired

You must specify a family for a task definition, which allows you to track multiple versions of the same task definition. The family is used as a name for your task definition. Up to 255 letters (uppercase and lowercase), numbers, hyphens, and underscores are allowed.

taskRoleArn = ::String

The short name or full Amazon Resource Name (ARN) of the IAM role that containers in this task can assume. All containers in this task are granted the permissions that are specified in this role. For more information, see IAM Roles for Tasks in the Amazon EC2 Container Service Developer Guide.

networkMode = "bridge", "host" or "none"

The Docker networking mode to use for the containers in the task. The valid values are none, bridge, and host.

The default Docker network mode is bridge. If the network mode is set to none, you cannot specify port mappings in your container definitions, and the task's containers do not have external connectivity. The host network mode offers the highest networking performance for containers because they use the host network stack instead of the virtualized network stack provided by the bridge mode; however, exposed container ports are mapped directly to the corresponding host port, so you cannot take advantage of dynamic host port mappings or run multiple instantiations of the same task on a single container instance if port mappings are used.

For more information, see Network settings in the Docker run reference.

containerDefinitions = [[ ... ], ...]Required

    ]

count = ::Int

The number of instantiations of the specified task to place on your cluster. You can specify up to 10 tasks per call.

startedBy = ::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 36 letters (uppercase and lowercase), numbers, hyphens, 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.

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).

placementConstraints = [[ ... ], ...]

An array of placement constraint objects to use for the task. You can specify up to 10 constraints per task (including constraints in the task definition and those specified at run time).

 placementConstraints = [[
        "type" =>  "distinctInstance" or "memberOf",
        "expression" =>  ::String
    ], ...]

placementStrategy = [[ ... ], ...]

The placement strategy objects to use for the task. You can specify a maximum of 5 strategy rules per task.

 placementStrategy = [[
        "type" =>  "random", "spread" or "binpack",
        "field" =>  ::String
    ], ...]

ecs([::AWSConfig], "StopTask", arguments::Dict)
ecs([::AWSConfig], "StopTask", task=, <keyword arguments>)

StopTask Operation

Stops a running task.

When StopTask is called on a task, the equivalent of docker stop is issued to the containers running in the task. This results in a SIGTERM and a default 30-second timeout, after which SIGKILL is sent and the containers are forcibly stopped. If the container handles the SIGTERM gracefully and exits within 30 seconds from receiving it, no SIGKILL is sent.

Note

The default 30-second timeout can be configured on the Amazon ECS container agent with the ECS_CONTAINER_STOP_TIMEOUT variable. For more information, see Amazon ECS Container Agent Configuration in the Amazon EC2 Container Service Developer Guide.

Arguments

cluster = ::String

The short name or full Amazon Resource Name (ARN) of the cluster that hosts the task to stop. If you do not specify a cluster, the default cluster is assumed.

task = ::StringRequired

The task ID or full Amazon Resource Name (ARN) entry of the task to stop.

reason = ::String

An optional message specified when a task is stopped. For example, if you are using a custom scheduler, you can use this parameter to specify the reason for stopping the task here, and the message will appear in subsequent DescribeTasks API operations on this task. Up to 255 characters are allowed in this message.

Returns

StopTaskResponse

Exceptions

ServerException, ClientException, InvalidParameterException or ClusterNotFoundException.

UpdateContainerAgent Operation

Updates the Amazon ECS container agent on a specified container instance. Updating the Amazon ECS container agent does not interrupt running tasks or services on the container instance. The process for updating the agent differs depending on whether your container instance was launched with the Amazon ECS-optimized AMI or another operating system.

UpdateContainerAgent requires the Amazon ECS-optimized AMI or Amazon Linux with the ecs-init service installed and running. For help updating the Amazon ECS container agent on other operating systems, see Manually Updating the Amazon ECS Container Agent in the Amazon EC2 Container Service Developer Guide.

Arguments

cluster = ::String

The short name or full Amazon Resource Name (ARN) of the cluster that your container instance is running on. If you do not specify a cluster, the default cluster is assumed.

containerInstance = ::StringRequired

UpdateContainerInstancesState Operation

Modifies the status of an Amazon ECS container instance.

You can change the status of a container instance to DRAINING to manually remove an instance from a cluster, for example to perform system updates, update the Docker daemon, or scale down the cluster size.

When you set a container instance to DRAINING, Amazon ECS prevents new tasks from being scheduled for placement on the container instance and replacement service tasks are started on other container instances in the cluster if the resources are available. Service tasks on the container instance that are in the PENDING state are stopped immediately.

Service tasks on the container instance that are in the RUNNING state are stopped and replaced according the service's deployment configuration parameters, minimumHealthyPercent and maximumPercent. Note that you can change the deployment configuration of your service using UpdateService.

  • If minimumHealthyPercent is below 100%, the scheduler can ignore desiredCount temporarily during task replacement. For example, desiredCount is four tasks, a minimum of 50% allows the scheduler to stop two existing tasks before starting two new tasks. If the minimum is 100%, the service scheduler can't remove existing tasks until the replacement tasks are considered healthy. Tasks for services that do not use a load balancer are considered healthy if they are in the RUNNING state. Tasks for services that use a load balancer are considered healthy if they are in the RUNNING state and the container instance they are hosted on is reported as healthy by the load balancer.

  • The maximumPercent parameter represents an upper limit on the number of running tasks during task replacement, which enables you to define the replacement batch size. For example, if desiredCount of four tasks, a maximum of 200% starts four new tasks before stopping the four tasks to be drained (provided that the cluster resources required to do this are available). If the maximum is 100%, then replacement tasks can't start until the draining tasks have stopped.

Any PENDING or RUNNING tasks that do not belong to a service are not affected; you must wait for them to finish or stop them manually.

A container instance has completed draining when it has no more RUNNING tasks. You can verify this using ListTasks.

When you set a container instance to ACTIVE, the Amazon ECS scheduler can begin scheduling tasks on the instance again.

Arguments

cluster = ::String

The short name or full Amazon Resource Name (ARN) of the cluster that hosts the container instance to update. If you do not specify a cluster, the default cluster is assumed.

containerInstances = [::String, ...]Required

A list of container instance IDs or full Amazon Resource Name (ARN) entries.

status = "ACTIVE" or "DRAINING"Required

The container instance state with which to update the container instance.

Returns

UpdateContainerInstancesStateResponse

Exceptions

ServerException, ClientException, InvalidParameterException or ClusterNotFoundException.

UpdateService Operation

Modifies the desired count, deployment configuration, or task definition used in a service.

You can add to or subtract from the number of instantiations of a task definition in a service by specifying the cluster that the service is running in and a new desiredCount parameter.

You can use UpdateService to modify your task definition and deploy a new version of your service.

You can also update the deployment configuration of a service. When a deployment is triggered by updating the task definition of a service, the service scheduler uses the deployment configuration parameters, minimumHealthyPercent and maximumPercent, to determine the deployment strategy.

  • If minimumHealthyPercent is below 100%, the scheduler can ignore desiredCount temporarily during a deployment. For example, if desiredCount is four tasks, a minimum of 50% allows the scheduler to stop two existing tasks before starting two new tasks. Tasks for services that do not use a load balancer are considered healthy if they are in the RUNNING state. Tasks for services that use a load balancer are considered healthy if they are in the RUNNING state and the container instance they are hosted on is reported as healthy by the load balancer.

  • The maximumPercent parameter represents an upper limit on the number of running tasks during a deployment, which enables you to define the deployment batch size. For example, if desiredCount is four tasks, a maximum of 200% starts four new tasks before stopping the four older tasks (provided that the cluster resources required to do this are available).

When UpdateService stops a task during a deployment, the equivalent of docker stop is issued to the containers running in the task. This results in a SIGTERM and a 30-second timeout, after which SIGKILL is sent and the containers are forcibly stopped. If the container handles the SIGTERM gracefully and exits within 30 seconds from receiving it, no SIGKILL is sent.

When the service scheduler launches new tasks, it determines task placement in your cluster with the following logic:

  • Determine which of the container instances in your cluster can support your service's task definition (for example, they have the required CPU, memory, ports, and container instance attributes).

  • By default, the service scheduler attempts to balance tasks across Availability Zones in this manner (although you can choose a different placement strategy):

    • Sort the valid container instances by the fewest number of running tasks for this service in the same Availability Zone as the instance. For example, if zone A has one running service task and zones B and C each have zero, valid container instances in either zone B or C are considered optimal for placement.

    • Place the new service task on a valid container instance in an optimal Availability Zone (based on the previous steps), favoring container instances with the fewest number of running tasks for this service.

When the service scheduler stops running tasks, it attempts to maintain balance across the Availability Zones in your cluster using the following logic:

  • Sort the container instances by the largest number of running tasks for this service in the same Availability Zone as the instance. For example, if zone A has one running service task and zones B and C each have two, container instances in either zone B or C are considered optimal for termination.

  • Stop the task on a container instance in an optimal Availability Zone (based on the previous steps), favoring container instances with the largest number of running tasks for this service.

Arguments

cluster = ::String

The short name or full Amazon Resource Name (ARN) of the cluster that your service is running on. If you do not specify a cluster, the default cluster is assumed.

service = ::StringRequired

taskDefinition = ::String

The family and revision (family:revision) or full Amazon Resource Name (ARN) of the task definition to run in your service. If a revision is not specified, the latest ACTIVE revision is used. If you modify the task definition with UpdateService, Amazon ECS spawns a task with the new version of the task definition and then stops an old task after the new version is running.

deploymentConfiguration = [ ... ]

Optional deployment parameters that control how many tasks run during the deployment and the ordering of stopping and starting tasks.

 deploymentConfiguration = [
        "maximumPercent" =>  ::Int,
