ECS
Service object for interacting with AWS ECS service.
public struct ECS: AWSService
Amazon Elastic Container Service (Amazon ECS) is a highly scalable, fast, container management service. It makes it easy to run, stop, and manage Docker containers on a cluster. You can host your cluster on a serverless infrastructure that's managed by Amazon ECS by launching your services or tasks on Fargate. For more control, you can host your tasks on a cluster of Amazon Elastic Compute Cloud (Amazon EC2) instances that you manage.
Amazon ECS makes it easy to launch and stop container-based applications with simple API calls. This makes it easy to get the state of your cluster from a centralized service, and gives you access to many familiar Amazon EC2 features.
You can use Amazon ECS to schedule the placement of containers across your cluster based on your resource needs, isolation policies, and availability requirements. With Amazon ECS, you don't need to operate your own cluster management and configuration management systems. You also don't need to worry about scaling your management infrastructure.

Methods
createCapacityProvider(_:logger:on:)
public func createCapacityProvider(_ input: CreateCapacityProviderRequest, logger: Logger = AWSClient.loggingDisabled, on eventLoop: EventLoop? = nil) -> EventLoopFuture<CreateCapacityProviderResponse>
Creates a new capacity provider. Capacity providers are associated with an Amazon ECS cluster and are used in capacity provider strategies to facilitate cluster auto scaling.
Only capacity providers that use an Auto Scaling group can be created. Amazon ECS tasks on
Fargate use the FARGATE
and FARGATE_SPOT
capacity providers.
These providers are available to all accounts in the Amazon Web Services Regions that Fargate
supports.
createCluster(_:logger:on:)
public func createCluster(_ input: CreateClusterRequest, logger: Logger = AWSClient.loggingDisabled, on eventLoop: EventLoop? = nil) -> EventLoopFuture<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 Amazon ECS service-linked role for your account. This is so that it can manage required resources in other Amazon Web Services services on your behalf. However, if the IAM user that makes the call doesn't have permissions to create the service-linked role, it isn't created. For more information, see Using Service-Linked Roles for Amazon ECS in the Amazon Elastic Container Service Developer Guide.
createService(_:logger:on:)
public func createService(_ input: CreateServiceRequest, logger: Logger = AWSClient.loggingDisabled, on eventLoop: EventLoop? = nil) -> EventLoopFuture<CreateServiceResponse>
Runs and maintains your desired number of tasks from a specified task definition. If
the number of tasks running in a service drops below the desiredCount
,
Amazon ECS runs another copy of the task in the specified cluster. To update an existing
service, see the UpdateService action.
In addition to maintaining the desired count of tasks in your service, you can optionally run your service behind one or more load balancers. The load balancers distribute 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.
Tasks for services that don't use a load balancer are considered healthy if they're in
the RUNNING
state. Tasks for services that use a load balancer are
considered healthy if they're in the RUNNING
state and are reported as healthy by the load balancer.
There are two service scheduler strategies available:
-
REPLICA
- The replica scheduling strategy places and maintains your desired number of tasks across your cluster. By default, the service scheduler spreads tasks across Availability Zones. You can use task placement strategies and constraints to customize task placement decisions. For more information, see Service Scheduler Concepts in the Amazon Elastic Container Service Developer Guide. -
DAEMON
- The daemon scheduling strategy deploys exactly one task on each active container instance that meets all of the task placement constraints that you specify in your cluster. The service scheduler also evaluates the task placement constraints for running tasks. It also stops tasks that don't meet the placement constraints. When using this strategy, you don't need to specify a desired number of tasks, a task placement strategy, or use Service Auto Scaling policies. For more information, see Service Scheduler Concepts in the Amazon Elastic Container Service Developer Guide.
You can optionally specify a deployment configuration for your service. The deployment
is initiated by changing properties. For example, the deployment might be initiated by
the task definition or by your desired count of a service. This is done with an UpdateService operation. The default value for a replica service for
minimumHealthyPercent
is 100%. The default value for a daemon service
for minimumHealthyPercent
is 0%.
If a service uses the ECS
deployment controller, the minimum healthy
percent represents a lower limit on the number of tasks in a service that must remain in
the RUNNING
state during a deployment. Specifically, it represents it as a
percentage of your desired number of tasks (rounded up to the nearest integer). This
happens when any of your container instances are in the DRAINING
state if
the service contains tasks using the EC2 launch type. Using this
parameter, you can deploy without using additional cluster capacity. For example, if you
set your service to have desired number of four tasks and a minimum healthy percent of
50%, the scheduler might stop two existing tasks to free up cluster capacity before
starting two new tasks. If they're in the RUNNING
state, tasks for services
that don't use a load balancer are considered healthy . If they're in the
RUNNING
state and reported as healthy by the load balancer, tasks for
services that do use a load balancer are considered healthy . The
default value for minimum healthy percent is 100%.
If a service uses the ECS
deployment controller, the maximum percent parameter represents an upper limit on the
number of tasks in a service that are allowed in the RUNNING
or
PENDING
state during a deployment. Specifically, it represents it as a
percentage of the desired number of tasks (rounded down to the nearest integer). This
happens when any of your container instances are in the DRAINING
state if
the service contains tasks using the EC2 launch type. Using this
parameter, you can define the deployment batch size. For example, if your service has a
desired number of four tasks and a maximum percent value of 200%, the scheduler may
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 maximum percent is
200%.
If a service uses either the CODE_DEPLOY
or EXTERNAL
deployment controller types and tasks that use the EC2 launch type, the
minimum healthy percent and maximum percent values are used only to define the lower and upper limit
on the number of the tasks in the service that remain in the RUNNING
state.
This is while the container instances are in the DRAINING
state. If the
tasks in the service use the Fargate launch type, the minimum healthy
percent and maximum percent values aren't used. This is the case even if they're
currently visible when describing your service.
When creating a service that uses the EXTERNAL
deployment controller, you
can specify only parameters that aren't controlled at the task set level. The only
required parameter is the service name. You control your services using the CreateTaskSet operation. For more information, see Amazon ECS Deployment Types in the Amazon Elastic Container Service Developer Guide.
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 the task definition of your service. 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. This is the case even if you can choose a different placement strategy with the
placementStrategy
parameter.-
Sort the valid container instances, giving priority to instances that have the fewest number of running tasks for this service in their respective Availability Zone. 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.
-
createTaskSet(_:logger:on:)
public func createTaskSet(_ input: CreateTaskSetRequest, logger: Logger = AWSClient.loggingDisabled, on eventLoop: EventLoop? = nil) -> EventLoopFuture<CreateTaskSetResponse>
Create a task set in the specified cluster and service. This is used when a service
uses the EXTERNAL
deployment controller type. For more information, see
Amazon ECS Deployment
Types in the Amazon Elastic Container Service Developer Guide.
deleteAccountSetting(_:logger:on:)
public func deleteAccountSetting(_ input: DeleteAccountSettingRequest, logger: Logger = AWSClient.loggingDisabled, on eventLoop: EventLoop? = nil) -> EventLoopFuture<DeleteAccountSettingResponse>
Disables an account setting for a specified IAM user, IAM role, or the root user for an account.
deleteAttributes(_:logger:on:)
public func deleteAttributes(_ input: DeleteAttributesRequest, logger: Logger = AWSClient.loggingDisabled, on eventLoop: EventLoop? = nil) -> EventLoopFuture<DeleteAttributesResponse>
Deletes one or more custom attributes from an Amazon ECS resource.
deleteCapacityProvider(_:logger:on:)
public func deleteCapacityProvider(_ input: DeleteCapacityProviderRequest, logger: Logger = AWSClient.loggingDisabled, on eventLoop: EventLoop? = nil) -> EventLoopFuture<DeleteCapacityProviderResponse>
Deletes the specified capacity provider.
The FARGATE
and FARGATE_SPOT
capacity providers are
reserved and can't be deleted. You can disassociate them from a cluster using either
the PutClusterCapacityProviders API or by deleting the
cluster.
Prior to a capacity provider being deleted, the capacity provider must be removed from
the capacity provider strategy from all services. The UpdateService
API can be used to remove a capacity provider from a service's capacity provider
strategy. When updating a service, the forceNewDeployment
option can be
used to ensure that any tasks using the Amazon EC2 instance capacity provided by the capacity
provider are transitioned to use the capacity from the remaining capacity providers.
Only capacity providers that aren't associated with a cluster can be deleted. To remove
a capacity provider from a cluster, you can either use PutClusterCapacityProviders or delete the cluster.
deleteCluster(_:logger:on:)
public func deleteCluster(_ input: DeleteClusterRequest, logger: Logger = AWSClient.loggingDisabled, on eventLoop: EventLoop? = nil) -> EventLoopFuture<DeleteClusterResponse>
Deletes the specified cluster. The cluster transitions to the INACTIVE
state. Clusters with an INACTIVE
status might remain discoverable in your
account for a period of time. However, this behavior is subject to change in the future.
We don't recommend that you rely on INACTIVE
clusters persisting.
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.
deleteService(_:logger:on:)
public func deleteService(_ input: DeleteServiceRequest, logger: Logger = AWSClient.loggingDisabled, on eventLoop: EventLoop? = nil) -> EventLoopFuture<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 can't 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 the ListServices
API operation. After all tasks have transitioned to either STOPPING
or
STOPPED
status, the service status moves from DRAINING
to INACTIVE
. Services in the DRAINING
or
INACTIVE
status can still be viewed with the DescribeServices API operation. However, in the future,
INACTIVE
services may be cleaned up and purged from Amazon ECS record
keeping, and DescribeServices calls on those services return a
ServiceNotFoundException
error.
If you attempt to create a new service with the same name as an existing service
in either ACTIVE
or DRAINING
status, you receive an
error.
deleteTaskSet(_:logger:on:)
public func deleteTaskSet(_ input: DeleteTaskSetRequest, logger: Logger = AWSClient.loggingDisabled, on eventLoop: EventLoop? = nil) -> EventLoopFuture<DeleteTaskSetResponse>
Deletes a specified task set within a service. This is used when a service uses the
EXTERNAL
deployment controller type. For more information, see Amazon ECS Deployment Types in the Amazon Elastic Container Service Developer Guide.
deregisterContainerInstance(_:logger:on:)
public func deregisterContainerInstance(_ input: DeregisterContainerInstanceRequest, logger: Logger = AWSClient.loggingDisabled, on eventLoop: EventLoop? = nil) -> EventLoopFuture<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, we recommend that you 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 doesn't 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 aren't automatically deregistered when terminated).
deregisterTaskDefinition(_:logger:on:)
public func deregisterTaskDefinition(_ input: DeregisterTaskDefinitionRequest, logger: Logger = AWSClient.loggingDisabled, on eventLoop: EventLoop? = nil) -> EventLoopFuture<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 can't use an INACTIVE
task definition to run new tasks or create new
services, and you can't update an existing service to reference an INACTIVE
task definition. However, 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. We
don't recommend that you rely on INACTIVE
task definitions persisting
beyond the lifecycle of any associated tasks and services.
describeCapacityProviders(_:logger:on:)
public func describeCapacityProviders(_ input: DescribeCapacityProvidersRequest, logger: Logger = AWSClient.loggingDisabled, on eventLoop: EventLoop? = nil) -> EventLoopFuture<DescribeCapacityProvidersResponse>
Describes one or more of your capacity providers.

describeTaskDefinition(_:logger:on:)
public func describeTaskDefinition(_ input: DescribeTaskDefinitionRequest, logger: Logger = AWSClient.loggingDisabled, on eventLoop: EventLoop? = nil) -> EventLoopFuture<DescribeTaskDefinitionResponse>
Describes a task definition. You can specify a family
and
revision
to find information about a specific task definition, or you
can simply specify the family to find the latest ACTIVE
revision in that
family.
You can only describe INACTIVE
task definitions while an active task
or service references them.
describeTaskSets(_:logger:on:)
public func describeTaskSets(_ input: DescribeTaskSetsRequest, logger: Logger = AWSClient.loggingDisabled, on eventLoop: EventLoop? = nil) -> EventLoopFuture<DescribeTaskSetsResponse>
Describes the task sets in the specified cluster and service. This is used when a
service uses the EXTERNAL
deployment controller type. For more information,
see Amazon ECS Deployment
Types in the Amazon Elastic Container Service Developer Guide.
describeTasks(_:logger:on:)
public func describeTasks(_ input: DescribeTasksRequest, logger: Logger = AWSClient.loggingDisabled, on eventLoop: EventLoop? = nil) -> EventLoopFuture<DescribeTasksResponse>
Describes a specified task or tasks.
discoverPollEndpoint(_:logger:on:)
public func discoverPollEndpoint(_ input: DiscoverPollEndpointRequest, logger: Logger = AWSClient.loggingDisabled, on eventLoop: EventLoop? = nil) -> EventLoopFuture<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.
executeCommand(_:logger:on:)
public func executeCommand(_ input: ExecuteCommandRequest, logger: Logger = AWSClient.loggingDisabled, on eventLoop: EventLoop? = nil) -> EventLoopFuture<ExecuteCommandResponse>
Runs a command remotely on a container within a task.
listAccountSettings(_:logger:on:)
public func listAccountSettings(_ input: ListAccountSettingsRequest, logger: Logger = AWSClient.loggingDisabled, on eventLoop: EventLoop? = nil) -> EventLoopFuture<ListAccountSettingsResponse>
Lists the account settings for a specified principal.
listAttributes(_:logger:on:)
public func listAttributes(_ input: ListAttributesRequest, logger: Logger = AWSClient.loggingDisabled, on eventLoop: EventLoop? = nil) -> EventLoopFuture<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. You can do this, for example,
to see which container instances in a cluster are running a Linux AMI
(ecs.os-type=linux
).
listClusters(_:logger:on:)
public func listClusters(_ input: ListClustersRequest, logger: Logger = AWSClient.loggingDisabled, on eventLoop: EventLoop? = nil) -> EventLoopFuture<ListClustersResponse>
Returns a list of existing clusters.
listContainerInstances(_:logger:on:)
public func listContainerInstances(_ input: ListContainerInstancesRequest, logger: Logger = AWSClient.loggingDisabled, on eventLoop: EventLoop? = nil) -> EventLoopFuture<ListContainerInstancesResponse>
Returns a list of container instances in a specified cluster. You can filter the
results of a ListContainerInstances
operation with cluster query language
statements inside the filter
parameter. For more information, see Cluster Query Language in the
Amazon Elastic Container Service Developer Guide.
listServices(_:logger:on:)
public func listServices(_ input: ListServicesRequest, logger: Logger = AWSClient.loggingDisabled, on eventLoop: EventLoop? = nil) -> EventLoopFuture<ListServicesResponse>
Returns a list of services. You can filter the results by cluster, launch type, and scheduling strategy.
listTagsForResource(_:logger:on:)
public func listTagsForResource(_ input: ListTagsForResourceRequest, logger: Logger = AWSClient.loggingDisabled, on eventLoop: EventLoop? = nil) -> EventLoopFuture<ListTagsForResourceResponse>
List the tags for an Amazon ECS resource.
listTaskDefinitionFamilies(_:logger:on:)
public func listTaskDefinitionFamilies(_ input: ListTaskDefinitionFamiliesRequest, logger: Logger = AWSClient.loggingDisabled, on eventLoop: EventLoop? = nil) -> EventLoopFuture<ListTaskDefinitionFamiliesResponse>
Returns a list of task definition families that are registered to your account. This
list includes task definition families that no longer have any ACTIVE
task
definition revisions.
You can filter out task definition families that don't contain any ACTIVE
task definition revisions by setting the status
parameter to
ACTIVE
. You can also filter the results with the
familyPrefix
parameter.
listTaskDefinitions(_:logger:on:)
public func listTaskDefinitions(_ input: ListTaskDefinitionsRequest, logger: Logger = AWSClient.loggingDisabled, on eventLoop: EventLoop? = nil) -> EventLoopFuture<ListTaskDefinitionsResponse>
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.
listTasks(_:logger:on:)
public func listTasks(_ input: ListTasksRequest, logger: Logger = AWSClient.loggingDisabled, on eventLoop: EventLoop? = nil) -> EventLoopFuture<ListTasksResponse>
Returns a list of tasks. You can filter the results by cluster, task definition family, container instance, launch type, what IAM principal started the task, or by the desired status of the task.
Recently stopped tasks might appear in the returned results. Currently, stopped tasks appear in the returned results for at least one hour.
putAccountSetting(_:logger:on:)
public func putAccountSetting(_ input: PutAccountSettingRequest, logger: Logger = AWSClient.loggingDisabled, on eventLoop: EventLoop? = nil) -> EventLoopFuture<PutAccountSettingResponse>
Modifies an account setting. Account settings are set on a per-Region basis.
If you change the account setting for the root user, the default settings for all of the IAM users and roles that no individual account setting was specified are reset for. For more information, see Account Settings in the Amazon Elastic Container Service Developer Guide.
When serviceLongArnFormat
, taskLongArnFormat
, or
containerInstanceLongArnFormat
are specified, the Amazon Resource Name
(ARN) and resource ID format of the resource type for a specified IAM user, IAM role, or
the root user for an account is affected. The opt-in and opt-out account setting must be
set for each Amazon ECS resource separately. The ARN and resource ID format of a resource is
defined by the opt-in status of the IAM user or role that created the resource. You must
turn on this setting to use Amazon ECS features such as resource tagging.
When awsvpcTrunking
is specified, the elastic network interface (ENI)
limit for any new container instances that support the feature is changed. If
awsvpcTrunking
is enabled, any new container instances that support the
feature are launched have the increased ENI limits available to them. For more
information, see Elastic Network
Interface Trunking in the Amazon Elastic Container Service Developer Guide.
When containerInsights
is specified, the default setting indicating
whether CloudWatch Container Insights is enabled for your clusters is changed. If
containerInsights
is enabled, any new clusters that are created will
have Container Insights enabled unless you disable it during cluster creation. For more
information, see CloudWatch
Container Insights in the Amazon Elastic Container Service Developer Guide.
putAccountSettingDefault(_:logger:on:)
public func putAccountSettingDefault(_ input: PutAccountSettingDefaultRequest, logger: Logger = AWSClient.loggingDisabled, on eventLoop: EventLoop? = nil) -> EventLoopFuture<PutAccountSettingDefaultResponse>
Modifies an account setting for all IAM users on an account for whom no individual account setting has been specified. Account settings are set on a per-Region basis.
putAttributes(_:logger:on:)
public func putAttributes(_ input: PutAttributesRequest, logger: Logger = AWSClient.loggingDisabled, on eventLoop: EventLoop? = nil) -> EventLoopFuture<PutAttributesResponse>
Create or update an attribute on an Amazon ECS resource. If the attribute doesn't exist, it's created. If the attribute exists, its value is replaced with the specified value. To delete an attribute, use DeleteAttributes. For more information, see Attributes in the Amazon Elastic Container Service Developer Guide.
putClusterCapacityProviders(_:logger:on:)
public func putClusterCapacityProviders(_ input: PutClusterCapacityProvidersRequest, logger: Logger = AWSClient.loggingDisabled, on eventLoop: EventLoop? = nil) -> EventLoopFuture<PutClusterCapacityProvidersResponse>
Modifies the available capacity providers and the default capacity provider strategy for a cluster.
You must specify both the available capacity providers and a default capacity provider strategy for the cluster. If the specified cluster has existing capacity providers associated with it, you must specify all existing capacity providers in addition to any new ones you want to add. Any existing capacity providers that are associated with a cluster that are omitted from a PutClusterCapacityProviders API call will be disassociated with the cluster. You can only disassociate an existing capacity provider from a cluster if it's not being used by any existing tasks.
When creating a service or running a task on a cluster, if no capacity provider or
launch type is specified, then the cluster's default capacity provider strategy is used.
We recommend that you define a default capacity provider strategy for your cluster.
However, you must specify an empty array ([]
) to bypass defining a default
strategy.
registerContainerInstance(_:logger:on:)
public func registerContainerInstance(_ input: RegisterContainerInstanceRequest, logger: Logger = AWSClient.loggingDisabled, on eventLoop: EventLoop? = nil) -> EventLoopFuture<RegisterContainerInstanceResponse>
This action is only used by the Amazon ECS agent, and it is not intended for use outside of the agent.
Registers an EC2 instance into the specified cluster. This instance becomes available to place containers on.
registerTaskDefinition(_:logger:on:)
public func registerTaskDefinition(_ input: RegisterTaskDefinitionRequest, logger: Logger = AWSClient.loggingDisabled, on eventLoop: EventLoop? = nil) -> EventLoopFuture<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 CLI or SDKs to make API requests to the Amazon Web Services services that are specified in
the IAM policy that's 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.
runTask(_:logger:on:)
public func runTask(_ input: RunTaskRequest, logger: Logger = AWSClient.loggingDisabled, on eventLoop: EventLoop? = nil) -> EventLoopFuture<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.
The Amazon ECS API follows an eventual consistency model. This is because of the distributed nature of the system supporting the API. This means that the result of an API command you run that affects your Amazon ECS resources might not be immediately visible to all subsequent commands you run. Keep this in mind when you carry out an API command that immediately follows a previous API command.
To manage eventual consistency, you can do the following:
-
Confirm the state of the resource before you run a command to modify it. Run the DescribeTasks command using an exponential backoff algorithm to ensure that you allow enough time for the previous command to propagate through the system. To do this, run the DescribeTasks command repeatedly, starting with a couple of seconds of wait time and increasing gradually up to five minutes of wait time.
-
Add wait time between subsequent commands, even if the DescribeTasks command returns an accurate response. Apply an exponential backoff algorithm starting with a couple of seconds of wait time, and increase gradually up to about five minutes of wait time.
startTask(_:logger:on:)
public func startTask(_ input: StartTaskRequest, logger: Logger = AWSClient.loggingDisabled, on eventLoop: EventLoop? = nil) -> EventLoopFuture<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.
stopTask(_:logger:on:)
public func stopTask(_ input: StopTaskRequest, logger: Logger = AWSClient.loggingDisabled, on eventLoop: EventLoop? = nil) -> EventLoopFuture<StopTaskResponse>
Stops a running task. Any tags associated with the task will be deleted.
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
value and a default 30-second timeout, after which the
SIGKILL
value is sent and the containers are forcibly stopped. If the
container handles the SIGTERM
value gracefully and exits within 30 seconds
from receiving it, no SIGKILL
value 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.
submitAttachmentStateChanges(_:logger:on:)
public func submitAttachmentStateChanges(_ input: SubmitAttachmentStateChangesRequest, logger: Logger = AWSClient.loggingDisabled, on eventLoop: EventLoop? = nil) -> EventLoopFuture<SubmitAttachmentStateChangesResponse>
This action is only used by the Amazon ECS agent, and it is not intended for use outside of the agent.
Sent to acknowledge that an attachment changed states.
submitContainerStateChange(_:logger:on:)
public func submitContainerStateChange(_ input: SubmitContainerStateChangeRequest, logger: Logger = AWSClient.loggingDisabled, on eventLoop: EventLoop? = nil) -> EventLoopFuture<SubmitContainerStateChangeResponse>
This action is only used by the Amazon ECS agent, and it is not intended for use outside of the agent.
Sent to acknowledge that a container changed states.
submitTaskStateChange(_:logger:on:)
public func submitTaskStateChange(_ input: SubmitTaskStateChangeRequest, logger: Logger = AWSClient.loggingDisabled, on eventLoop: EventLoop? = nil) -> EventLoopFuture<SubmitTaskStateChangeResponse>
This action is only used by the Amazon ECS agent, and it is not intended for use outside of the agent.
Sent to acknowledge that a task changed states.
tagResource(_:logger:on:)
public func tagResource(_ input: TagResourceRequest, logger: Logger = AWSClient.loggingDisabled, on eventLoop: EventLoop? = nil) -> EventLoopFuture<TagResourceResponse>
Associates the specified tags to a resource with the specified
resourceArn
. If existing tags on a resource aren't specified in the
request parameters, they aren't changed. When a resource is deleted, the tags that are
associated with that resource are deleted as well.
untagResource(_:logger:on:)
public func untagResource(_ input: UntagResourceRequest, logger: Logger = AWSClient.loggingDisabled, on eventLoop: EventLoop? = nil) -> EventLoopFuture<UntagResourceResponse>

updateContainerAgent(_:logger:on:)
public func updateContainerAgent(_ input: UpdateContainerAgentRequest, logger: Logger = AWSClient.loggingDisabled, on eventLoop: EventLoop? = nil) -> EventLoopFuture<UpdateContainerAgentResponse>
Updates the Amazon ECS container agent on a specified container instance. Updating the Amazon ECS container agent doesn't 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.
The UpdateContainerAgent
API isn't supported for container instances
using the Amazon ECS-optimized Amazon Linux 2 (arm64) AMI. To update the container agent,
you can update the ecs-init
package. This updates the agent. For more
information, see Updating the
Amazon ECS container agent in the
Amazon Elastic Container Service Developer Guide.
The UpdateContainerAgent
API requires an Amazon ECS-optimized AMI or Amazon
Linux AMI 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.
updateContainerInstancesState(_:logger:on:)
public func updateContainerInstancesState(_ input: UpdateContainerInstancesStateRequest, logger: Logger = AWSClient.loggingDisabled, on eventLoop: EventLoop? = nil) -> EventLoopFuture<UpdateContainerInstancesStateResponse>
Modifies the status of an Amazon ECS container instance.
Once a container instance has reached an ACTIVE
state, 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.
A container instance can't be changed to DRAINING
until it has
reached an ACTIVE
status. If the instance is in any other status, an
error will be received.
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 ignoredesiredCount
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're in theRUNNING
state. Tasks for services that use a load balancer are considered healthy if they're in theRUNNING
state and are reported as healthy by the load balancer. -
The
maximumPercent
parameter represents an upper limit on the number of running tasks during task replacement. You can use this to define the replacement batch size. For example, ifdesiredCount
is 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
aren't 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 a container instance has been drained, you can set a container instance to
ACTIVE
status and once it has reached that status the Amazon ECS scheduler
can begin scheduling tasks on the instance again.
updateService(_:logger:on:)
public func updateService(_ input: UpdateServiceRequest, logger: Logger = AWSClient.loggingDisabled, on eventLoop: EventLoop? = nil) -> EventLoopFuture<UpdateServiceResponse>
Updating the task placement strategies and constraints on an Amazon ECS service remains in preview and is a Beta Service as defined by and subject to the Beta Service Participation Service Terms located at https://aws.amazon.com/service-terms ("Beta Terms"). These Beta Terms apply to your participation in this preview.
Modifies the parameters of a service.
For services using the rolling update (ECS
) you can update the desired count,
deployment configuration, network configuration, load balancers, service registries,
enable ECS managed tags option, propagate tags option, task placement constraints and
strategies, and task definition. When you update any of these parameters, Amazon ECS starts
new tasks with the new configuration.
For services using the blue/green (CODE_DEPLOY
) deployment controller, only the
desired count, deployment configuration, health check grace period, task placement
constraints and strategies, enable ECS managed tags option, and propagate tags can be
updated using this API. If the network configuration, platform version, task definition,
or load balancer need to be updated, create a new CodeDeploy deployment. For more
information, see CreateDeployment in the CodeDeploy API Reference.
For services using an external deployment controller, you can update only the desired count, task placement constraints and strategies, health check grace period, enable ECS managed tags option, and propagate tags option, using this API. If the launch type, load balancer, network configuration, platform version, or task definition need to be updated, create a new task set For more information, see CreateTaskSet.
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.
If you have updated the Docker image of your application, you can create a new task definition with that image and deploy it to your service. The service scheduler uses the minimum healthy percent and maximum percent parameters (in the service's deployment configuration) to determine the deployment strategy.
If your updated Docker image uses the same tag as what is in the existing task
definition for your service (for example, my_image:latest
), you don't
need to create a new revision of your task definition. You can update the service
using the forceNewDeployment
option. The new tasks launched by the
deployment pull the current image/tag combination from your repository when they
start.
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 ignoredesiredCount
temporarily during a deployment. For example, ifdesiredCount
is four tasks, a minimum of 50% allows the scheduler to stop two existing tasks before starting two new tasks. Tasks for services that don't use a load balancer are considered healthy if they're in theRUNNING
state. Tasks for services that use a load balancer are considered healthy if they're in theRUNNING
state and are reported as healthy by the load balancer. -
The
maximumPercent
parameter represents an upper limit on the number of running tasks during a deployment. You can use it to define the deployment batch size. For example, ifdesiredCount
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 this,
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 even though 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.
-
<p>When the service scheduler stops running tasks, it attempts to maintain balance across
the Availability Zones in your cluster using the following logic: </p>
<ul>
<li>
<p>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.</p>
</li>
<li>
<p>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.</p>
</li>
</ul>
<note>
<p>You must have a service-linked role when you update any of the following service properties.
If you specified a custom IAM role when you created the service, Amazon ECS automatically
replaces the <a href="https://docs.aws.amazon.com/AmazonECS/latest/APIReference/API_Service.html#ECS-Type-Service-roleArn">roleARN</a> associated with the service with the ARN of your service-linked
role. For more information, see <a href="https://docs.aws.amazon.com/AmazonECS/latest/developerguide/using-service-linked-roles.html">Service-linked
