AsyncHandler can be used to receive
notification when an asynchronous operation completes.
Note: Do not directly implement this interface, new methods are added to it regularly. Extend from
AbstractAmazonECSAsync instead.
Amazon Elastic 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. You can host your cluster on a serverless infrastructure that is managed by Amazon ECS by launching your services or tasks on AWS 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, allows you 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. Amazon ECS eliminates the need for you to operate your own cluster management and configuration management systems or worry about scaling your management infrastructure.

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 using an Auto Scaling group can be created. Amazon ECS tasks on AWS Fargate use the
FARGATE and FARGATE_SPOT capacity providers which are already created and available to
all accounts in Regions supported by AWS Fargate.

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 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.

Runs and maintains a 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 do not use a load balancer are considered healthy if they're in the
RUNNING state. Tasks for services that do use a load balancer are considered healthy if
they're in the RUNNING state and the container instance that they're hosted on is reported as
healthy by the load balancer.
There are two service scheduler strategies available:
REPLICA - The replica scheduling strategy places and maintains the 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 and will stop tasks that do not 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 triggered by changing
properties, such as the task definition or the desired count of a service, 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 is using 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,
as a percentage of the desired number of tasks (rounded up to the nearest integer), and while any container
instances are in the DRAINING state if the service contains tasks using the EC2 launch type. This
parameter enables you to deploy without using additional cluster capacity. For example, if your service has a
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. Tasks for services that do not use a load balancer
are considered healthy if they're in the RUNNING state. Tasks for services that do use a load
balancer are considered healthy if they're in the RUNNING state and they're reported as healthy by
the load balancer. The default value for minimum healthy percent is 100%.
If a service is using 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, as a percentage of the desired number of tasks (rounded down to
the nearest integer), and while any container instances are in the DRAINING state if the service
contains tasks using the EC2 launch type. This parameter enables you to 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 is using 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 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,
although 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 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, 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.

The FARGATE and FARGATE_SPOT capacity providers are reserved and cannot 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 are not
associated with a cluster can be deleted. To remove a capacity provider from a cluster, you can either use
PutClusterCapacityProviders or delete the cluster.

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 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.

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).

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. 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, so you should not rely on INACTIVE task
definitions persisting beyond the lifecycle of any associated tasks and services.

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, due to 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.

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.

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 cannot 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 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 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 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 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.

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) deployment controller, the desired count, deployment
configuration, network configuration, task placement constraints and strategies, or task definition used can be
updated.
For services using the blue/green (CODE_DEPLOY) deployment controller, only the desired count,
deployment configuration, task placement constraints and strategies, and health check grace period can be updated
using this API. If the network configuration, platform version, or task definition need to be updated, a new AWS
CodeDeploy deployment should be created. For more information, see CreateDeployment
in the AWS CodeDeploy API Reference.
For services using an external deployment controller, you can update only the desired count, task placement constraints and strategies, and health check grace period using this API. If the launch type, load balancer, network configuration, platform version, or task definition need to be updated, you should 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 do not 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 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.
