Class: Aws::ECS::Client

Inherits:
Seahorse::Client::Base show all
Defined in:
(unknown)

Overview

An API client for Amazon EC2 Container Service. To construct a client, you need to configure a :region and :credentials.

ecs = Aws::ECS::Client.new(
  region: region_name,
  credentials: credentials,
  # ...
)

See #initialize for a full list of supported configuration options.

Region

You can configure a default region in the following locations:

  • ENV['AWS_REGION']
  • Aws.config[:region]

Go here for a list of supported regions.

Credentials

Default credentials are loaded automatically from the following locations:

  • ENV['AWS_ACCESS_KEY_ID'] and ENV['AWS_SECRET_ACCESS_KEY']
  • Aws.config[:credentials]
  • The shared credentials ini file at ~/.aws/credentials (more information)
  • From an instance profile when running on EC2

You can also construct a credentials object from one of the following classes:

Alternatively, you configure credentials with :access_key_id and :secret_access_key:

# load credentials from disk
creds = YAML.load(File.read('/path/to/secrets'))

Aws::ECS::Client.new(
  access_key_id: creds['access_key_id'],
  secret_access_key: creds['secret_access_key']
)

Always load your credentials from outside your application. Avoid configuring credentials statically and never commit them to source control.

Instance Method Details

#create_cluster(options = {}) ⇒ Types::CreateClusterResponse

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.

When you call the CreateCluster API operation, Amazon ECS attempts to create the service-linked role for your account so that required resources in other AWS services can be managed on your behalf. However, if the IAM user that makes the call does not have permissions to create the service-linked role, it is not created. For more information, see Using Service-Linked Roles for Amazon ECS in the Amazon Elastic Container Service Developer Guide.

Examples:

Example: To create a new cluster


# This example creates a cluster in your default region.

resp = client.create_cluster({
  cluster_name: "my_cluster", 
})

# resp.to_h outputs the following:
{
  cluster: {
    active_services_count: 0, 
    cluster_arn: "arn:aws:ecs:us-east-1:012345678910:cluster/my_cluster", 
    cluster_name: "my_cluster", 
    pending_tasks_count: 0, 
    registered_container_instances_count: 0, 
    running_tasks_count: 0, 
    status: "ACTIVE", 
  }, 
}

Options Hash (options):

  • :cluster_name (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:

#create_service(options = {}) ⇒ Types::CreateServiceResponse

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 Elastic Container Service Developer Guide.

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

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.

Examples:

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.

Options Hash (options):

  • :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.

  • :service_name (required, String)

    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.

  • :task_definition (required, String)

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

  • :load_balancers (Array<Types::LoadBalancer>)

    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.

  • :desired_count (required, Integer)

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

  • :client_token (String)

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

  • :launch_type (String)

    The launch type on which to run your service.

  • :platform_version (String)

    The platform version on which to run your service. If one is not specified, the latest version is used by default.

  • :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 only permitted if you are using a load balancer with your service and your task definition does not use the awsvpc network mode. If you specify the role parameter, you must also specify a load balancer object with the loadBalancers parameter.

    If your account has already created the Amazon ECS service-linked role, that role is used by default for your service unless you specify a role here. The service-linked role is required if your task definition uses the awsvpc network mode, in which case you should not specify a role here. For more information, see Using Service-Linked Roles for Amazon ECS in the Amazon Elastic Container Service Developer Guide.

    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.

  • :deployment_configuration (Types::DeploymentConfiguration)

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

  • :placement_constraints (Array<Types::PlacementConstraint>)

    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).

  • :placement_strategy (Array<Types::PlacementStrategy>)

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

  • :network_configuration (Types::NetworkConfiguration)

    The network configuration for the service. This parameter is required for task definitions that use the awsvpc network mode to receive their own Elastic Network Interface, and it is not supported for other network modes. For more information, see Task Networking in the Amazon Elastic Container Service Developer Guide.

Returns:

#delete_service(options = {}) ⇒ Types::DeleteServiceResponse

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.

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 return a ServiceNotFoundException error.

Examples:

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.

resp = client.delete_service({
  service: "my-http-service",

#deregister_container_instance(options = {}) ⇒ Types::DeregisterContainerInstanceResponse

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. That prevents 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.

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).

Examples:

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.

resp = client.deregister_container_instance({
  cluster: "default",

  force: true,

Options Hash (options):

  • :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.

  • :container_instance (required, String)

    The container instance ID or full 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 (Boolean)

    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. They begin connection draining according to the settings on the load balancer or target group.

Returns:

See Also:

#deregister_task_definition(options = {}) ⇒ Types::DeregisterTaskDefinitionResponse

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).

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 lifecycle of any associated tasks and services.

#discover_poll_endpoint(options = {}) ⇒ Types::DiscoverPollEndpointResponse

This action is only used by the Amazon ECS agent, and it is not intended for use outside of the agent.

Returns an endpoint for the Amazon ECS agent to poll for updates.

Examples:

Request syntax with placeholder values


resp = client.discover_poll_endpoint({
  container_instance: "String",

})

Response structure


resp.endpoint #=> String
resp.telemetry_endpoint #=> String

Options Hash (options):

  • :container_instance (String)

    The container instance ID or full ARN of the container instance. 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 .

  • :cluster (String)

    The short name or full Amazon Resource Name (ARN) of the cluster that the container instance belongs to.

Returns:

See Also:

#list_attributes(options = {}) ⇒ Types::ListAttributesResponse

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).

Examples:

resp = client.list_attributes({
  cluster: "String",
  target_type: "container-instance", # required, accepts container-instance

resp.attributes[0].value #=> String
resp.attributes[0].target_type #=> String, one of "container-instance"
resp.attributes[0].target_id #=> String
resp.next_token #=> String

Options Hash (options):

  • :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.

  • :target_type (required, String)

    The type of the target with which to list attributes.

  • :attribute_name (String)

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

  • :attribute_value (String)

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

  • :next_token (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 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.

  • :max_results (Integer)

    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.

  • :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.

  • :next_token (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 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.

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.

  • :started_by (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.

  • :service_name (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.

  • :desired_status (String)

    The task desired status with which to filter the ListTasks results. Specifying a desiredStatus of STOPPED limits the results to tasks that Amazon 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 Amazon ECS has set the desired status to RUNNING.

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

  • :launch_type (String)

    The launch type for services you want to list.

Returns:

#register_task_definition(options = {}) ⇒ Types::RegisterTaskDefinitionResponse

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 Elastic 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 Elastic 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. If you specify the awsvpc network mode, the task is allocated an Elastic Network Interface, and you must specify a NetworkConfiguration when you create a service or run a task with the task definition. For more information, see Task Networking in the Amazon Elastic Container Service Developer Guide.

Options Hash (options):

  • :family (required, String)

    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.

  • :task_role_arn (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 Elastic Container Service Developer Guide.

  • :execution_role_arn (String)

    The Amazon Resource Name (ARN) of the task execution role that the Amazon ECS container agent and the Docker daemon can assume.

  • :network_mode (String)

    The Docker networking mode to use for the containers in the task. The valid values are none, bridge, awsvpc, and host. The default Docker network mode is bridge. If using the Fargate launch type, the awsvpc network mode is required. If using the EC2 launch type, any network mode can be used. If the network mode is set to none, you can\'t specify port mappings in your container definitions, and the task\'s containers do not have external connectivity. The host and awsvpc network modes offer the highest networking performance for containers because they use the EC2 network stack instead of the virtualized network stack provided by the bridge mode.

    With the host and awsvpc network modes, exposed container ports are mapped directly to the corresponding host port (for the host network mode) or the attached elastic network interface port (for the awsvpc network mode), so you cannot take advantage of dynamic host port mappings.

    If the network mode is awsvpc, the task is allocated an Elastic Network Interface, and you must specify a NetworkConfiguration when you create a service or run a task with the task definition. For more information, see Task Networking in the Amazon Elastic Container Service Developer Guide.

    If the network mode is host, you can\'t run multiple instantiations of the same task on a single container instance when port mappings are used.

    Docker for Windows uses different network modes than Docker for Linux. When you register a task definition with Windows containers, you must not specify a network mode.

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

  • :container_definitions (required, Array<Types::ContainerDefinition>)

    A list of container definitions in JSON format that describe the different containers that make up your task.

  • :volumes (Array<Types::Volume>)

    A list of volume definitions in JSON format that containers in your task may use.

  • :placement_constraints (Array<Types::TaskDefinitionPlacementConstraint>)

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

  • :requires_compatibilities (Array<String>)

    The launch type required by the task. If no value is specified, it defaults to EC2.

  • :cpu (String)

    The number of cpu units used by the task. If using the EC2 launch type, this field is optional and any value can be used. If you are using the Fargate launch type, this field is required and you must use one of the following values, which determines your range of valid values for the memory parameter:

    • 256 (.25 vCPU) - Available memory values: 512MB, 1GB, 2GB

    • 512 (.5 vCPU) - Available memory values: 1GB, 2GB, 3GB, 4GB

    • 1024 (1 vCPU) - Available memory values: 2GB, 3GB, 4GB, 5GB, 6GB, 7GB, 8GB

    • 2048 (2 vCPU) - Available memory values: Between 4GB and 16GB in 1GB increments

    • 4096 (4 vCPU) - Available memory values: Between 8GB and 30GB in 1GB increments

  • :memory (String)

    The amount (in MiB) of memory used by the task. If using the EC2 launch type, this field is optional and any value can be used. If you are using the Fargate launch type, this field is required and you must use one of the following values, which determines your range of valid values for the cpu parameter:

    • 512MB, 1GB, 2GB - Available cpu values: 256 (.25 vCPU)

    • 1GB, 2GB, 3GB, 4GB - Available cpu values: 512 (.5 vCPU)

    • 2GB, 3GB, 4GB, 5GB, 6GB, 7GB, 8GB - Available cpu values: 1024 (1 vCPU)

    • Between 4GB and 16GB in 1GB increments - Available cpu values: 2048 (2 vCPU)

    • Between 8GB and 30GB in 1GB increments - Available cpu values: 4096 (4 vCPU)

#run_task(options = {}) ⇒ Types::RunTaskResponse

Starts a new task using the specified task definition.

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.

Options Hash (options):

  • :cluster (String)

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

  • :task_definition (required, String)

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

  • :overrides (Types::TaskOverride)

    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 is 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.

  • :count (Integer)

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

  • :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 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).

  • :placement_constraints (Array<Types::PlacementConstraint>)

    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).

  • :placement_strategy (Array<Types::PlacementStrategy>)

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

  • :launch_type (String)

    The launch type on which to run your task.

  • :platform_version (String)

    The platform version on which to run your task. If one is not specified, the latest version is used by default.

  • :network_configuration (Types::NetworkConfiguration)

    The network configuration for the task. This parameter is required for task definitions that use the awsvpc network mode to receive their own Elastic Network Interface, and it is not supported for other network modes. For more information, see Task Networking in the Amazon Elastic Container Service Developer Guide.

Returns:

See Also:

#start_task(options = {}) ⇒ Types::StartTaskResponse

Starts a new task from the specified task definition on the specified container instance or instances.

Alternatively, you can use RunTask to place tasks for you. For more information, see Scheduling Tasks in the Amazon Elastic Container Service Developer Guide.

Options Hash (options):

  • :cluster (String)

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

  • :task_definition (required, String)

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

  • :overrides (Types::TaskOverride)

    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 is 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.

  • :container_instances (required, Array<String>)

    The container instance IDs or full ARN entries for the container instances on which you would like to place your task. You can specify up to 10 container instances.

  • :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 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).

  • :network_configuration (Types::NetworkConfiguration)

    The VPC subnet and security group configuration for tasks that receive their own Elastic Network Interface by using the awsvpc networking mode.

Returns:

#stop_task(options = {}) ⇒ Types::StopTaskResponse

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.

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 Elastic Container Service Developer Guide.

#update_container_agent(options = {}) ⇒ Types::UpdateContainerAgentResponse

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 Elastic Container Service Developer Guide.

#update_container_instances_state(options = {}) ⇒ Types::UpdateContainerInstancesStateResponse

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 to the service's deployment configuration parameters, minimumHealthyPercent and maximumPercent. 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.

#update_service(options = {}) ⇒ Types::UpdateServiceResponse

Modifies the desired count, deployment configuration, network 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.

Options Hash (options):

  • :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 (required, String)

    The name of the service to update.

  • :desired_count (Integer)

    The number of instantiations of the task to place and keep running in your service.

  • :task_definition (String)

    The family and revision (family:revision) or full 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.

  • :deployment_configuration (Types::DeploymentConfiguration)

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

  • :network_configuration (Types::NetworkConfiguration)

    The network configuration for the service. This parameter is required for task definitions that use the awsvpc network mode to receive their own Elastic Network Interface, and it is not supported for other network modes. For more information, see Task Networking in the Amazon Elastic Container Service Developer Guide.

    Updating a service to add a subnet to a list of existing subnets does not trigger a service deployment. For example, if your network configuration change is to keep the existing subnets and simply add another subnet to the network configuration, this does not trigger a new service deployment.

  • :platform_version (String)

    The platform version you want to update your service to run.

  • :force_new_deployment (Boolean)

    Whether or not to force a new deployment of the service.

Returns:

#wait_until(waiter_name, params = {}) {|waiter| ... } ⇒ Boolean

Waiters polls an API operation until a resource enters a desired state.

Basic Usage

Waiters will poll until they are succesful, they fail by entering a terminal state, or until a maximum number of attempts are made.

# polls in a loop, sleeping between attempts client.waiter_until(waiter_name, params)

Configuration

You can configure the maximum number of polling attempts, and the delay (in seconds) between each polling attempt. You configure waiters by passing a block to #wait_until:

# poll for ~25 seconds
client.wait_until(...) do |w|
  w.max_attempts = 5
  w.delay = 5
end

Callbacks

You can be notified before each polling attempt and before each delay. If you throw :success or :failure from these callbacks, it will terminate the waiter.

started_at = Time.now
client.wait_until(...) do |w|

  # disable max attempts
  w.max_attempts = nil

  # poll for 1 hour, instead of a number of attempts
  w.before_wait do |attempts, response|
    throw :failure if Time.now - started_at > 3600
  end

end

Handling Errors

When a waiter is successful, it returns true. When a waiter fails, it raises an error. All errors raised extend from Waiters::Errors::WaiterFailed.

begin
  client.wait_until(...)
rescue Aws::Waiters::Errors::WaiterFailed
  # resource did not enter the desired state in time
end

Parameters:

  • waiter_name (Symbol)

    The name of the waiter. See #waiter_names for a full list of supported waiters.

  • params (Hash) (defaults to: {})

    Additional request parameters. See the #waiter_names for a list of supported waiters and what request they call. The called request determines the list of accepted parameters.

Yield Parameters:

Returns:

  • (Boolean)

    Returns true if the waiter was successful.

Raises:

  • (Errors::FailureStateError)

    Raised when the waiter terminates because the waiter has entered a state that it will not transition out of, preventing success.

  • (Errors::TooManyAttemptsError)

    Raised when the configured maximum number of attempts have been made, and the waiter is not yet successful.

  • (Errors::UnexpectedError)

    Raised when an error is encounted while polling for a resource that is not expected.

  • (Errors::NoSuchWaiterError)

    Raised when you request to wait for an unknown state.

#waiter_namesArray<Symbol>
