builder() method.
Amazon EC2 Container Service (Amazon ECS) is a highly scalable, fast, container management service that makes it easy to run, stop, and manage Docker containers on a cluster of EC2 instances. Amazon ECS lets you launch and stop container-enabled applications with simple API calls, allows you to get the state of your cluster from a centralized service, and gives you access to many familiar Amazon EC2 features like security groups, Amazon EBS volumes, and IAM roles.
You can use Amazon ECS to schedule the placement of containers across your cluster based on your resource needs, isolation policies, and availability requirements. Amazon EC2 Container Service eliminates the need for you to operate your own cluster management and configuration management systems or worry about scaling your management infrastructure.

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.
createClusterRequest - ServerException - These errors are usually caused by a server issue.ClientException - These errors are usually caused by a client action, such as using an action or resource on behalf of a

Runs and maintains a desired number of tasks from a specified task definition. If the number of tasks running in
a service drops below desiredCount, Amazon ECS spawns another copy of the task in the specified
cluster. To update an existing service, see UpdateService.
In addition to maintaining the desired count of tasks in your service, you can optionally run your service behind a load balancer. The load balancer distributes traffic across the tasks that are associated with the service. For more information, see Service Load Balancing in the Amazon EC2 Container Service Developer Guide.
You can optionally specify a deployment configuration for your service. During a deployment (which is triggered
by changing the task definition or the desired count of a service with an UpdateService operation), the
service scheduler uses the minimumHealthyPercent and maximumPercent parameters to
determine the deployment strategy.
The minimumHealthyPercent represents a lower limit on the number of your service's tasks that must
remain in the RUNNING state during a deployment, as a percentage of the desiredCount
(rounded up to the nearest integer). This parameter enables you to deploy without using additional cluster
capacity. For example, if your service has a desiredCount of four tasks and a
minimumHealthyPercent of 50%, the scheduler can stop two existing tasks to free up cluster capacity
before starting two new tasks. Tasks for services that do not use a load balancer are considered healthy
if they are in the RUNNING state. Tasks for services that do use a load balancer are
considered healthy if they are in the RUNNING state and the container instance they are hosted on is
reported as healthy by the load balancer. The default value for minimumHealthyPercent is 50% in the
console and 100% for the AWS CLI, the AWS SDKs, and the APIs.
The maximumPercent parameter represents an upper limit on the number of your service's tasks that
are allowed in the RUNNING or PENDING state during a deployment, as a percentage of the
desiredCount (rounded down to the nearest integer). This parameter enables you to define the
deployment batch size. For example, if your service has a desiredCount of four tasks and a
maximumPercent value of 200%, the scheduler can start four new tasks before stopping the four older
tasks (provided that the cluster resources required to do this are available). The default value for
maximumPercent is 200%.
When the service scheduler launches new tasks, it determines task placement in your cluster using the following logic:
Determine which of the container instances in your cluster can support your service's task definition (for example, they have the required CPU, memory, ports, and container instance attributes).
By default, the service scheduler attempts to balance tasks across Availability Zones in this manner (although
you can choose a different placement strategy) with the placementStrategy parameter):
Sort the valid container instances by the fewest number of running tasks for this service in the same Availability Zone as the instance. For example, if zone A has one running service task and zones B and C each have zero, valid container instances in either zone B or C are considered optimal for placement.
Place the new service task on a valid container instance in an optimal Availability Zone (based on the previous steps), favoring container instances with the fewest number of running tasks for this service.

Deletes the specified cluster. You must deregister all container instances from this cluster before you may delete it. You can list the container instances in a cluster with ListContainerInstances and deregister them with DeregisterContainerInstance.
deleteClusterRequest - ServerException - These errors are usually caused by a server issue.ClientException - These errors are usually caused by a client action, such as using an action or resource on behalf of a

Amazon ECS clusters are region-specific.ClusterContainsContainerInstancesException - You cannot delete a cluster that has registered container instances. You must first deregister the
container instances before you can delete the cluster. For more information, see
DeregisterContainerInstance.ClusterContainsServicesException - You cannot delete a cluster that contains services. You must first update the service to reduce its
desired task count to 0 and then delete the service. For more information, see UpdateService and

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 will return a ServiceNotFoundException
error.

Unknown exceptions will be thrown as an instance of this typedefault DeregisterContainerInstanceResponse deregisterContainerInstance(DeregisterContainerInstanceRequest deregisterContainerInstanceRequest) throws ServerException, ClientException, InvalidParameterException, ClusterNotFoundException, SdkBaseException, SdkClientException, ECSException
Deregisters an Amazon ECS container instance from the specified cluster. This instance is no longer available to run tasks.
If you intend to use the container instance for some other purpose after deregistration, you should stop all of the tasks running on the container instance before deregistration to avoid any orphaned tasks from consuming resources.
Deregistering a container instance removes the instance from a cluster, but it does not terminate the EC2 instance; if you are finished using the instance, be sure to terminate it in the Amazon EC2 console to stop billing.
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).
deregisterContainerInstanceRequest - ServerException - These errors are usually caused by a server issue.ClientException - These errors are usually caused by a client action, such as using an action or resource on behalf of a
user that doesn't have permission to use the action or resource, or specifying an identifier that is not

Unknown exceptions will be thrown as an instance of this typedefault DeregisterTaskDefinitionResponse deregisterTaskDefinition(DeregisterTaskDefinitionRequest deregisterTaskDefinitionRequest) throws ServerException, ClientException, InvalidParameterException, SdkBaseException, SdkClientException, ECSException
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 life cycle of any associated tasks and services.

information about task definition parameters and defaults, see Amazon ECS Task
Definitions in the Amazon EC2 Container Service Developer Guide.
You can specify an IAM role for your task with the taskRoleArn parameter. When you specify an IAM
role for a task, its containers can then use the latest versions of the AWS CLI or SDKs to make API requests to
the AWS services that are specified in the IAM policy associated with the role. For more information, see IAM Roles for Tasks in
the Amazon EC2 Container Service Developer Guide.
You can specify a Docker networking mode for the containers in your task definition with the
networkMode parameter. The available network modes correspond to those described in Network settings in the Docker run
reference.

Unknown exceptions will be thrown as an instance of this typedefault StopTaskResponse stopTask(StopTaskRequest stopTaskRequest) throws ServerException, ClientException, InvalidParameterException, ClusterNotFoundException, SdkBaseException, SdkClientException, ECSException
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 EC2 Container Service Developer Guide.

Updates the Amazon ECS container agent on a specified container instance. Updating the Amazon ECS container agent does not interrupt running tasks or services on the container instance. The process for updating the agent differs depending on whether your container instance was launched with the Amazon ECS-optimized AMI or another operating system.
UpdateContainerAgent requires the Amazon ECS-optimized AMI or Amazon Linux with the
ecs-init service installed and running. For help updating the Amazon ECS container agent on other
operating systems, see Manually Updating the Amazon ECS Container Agent in the Amazon EC2 Container Service Developer Guide.

PENDING or STAGING, the update process can get stuck in that state. However,
when the agent reconnects, it resumes where it stopped previously.NoUpdateAvailableException - There is no update available for this Amazon ECS container agent. This could be because the agent is
already running the latest version, or it is so old that there is no update path to the current version.MissingVersionException - Amazon ECS is unable to determine the current version of the Amazon ECS container agent on the container

Modifies the status of an Amazon ECS container instance.
You can change the status of a container instance to DRAINING to manually remove an instance from a
cluster, for example to perform system updates, update the Docker daemon, or scale down the cluster size.
When you set a container instance to DRAINING, Amazon ECS prevents new tasks from being scheduled
for placement on the container instance and replacement service tasks are started on other container instances in
the cluster if the resources are available. Service tasks on the container instance that are in the
PENDING state are stopped immediately.
Service tasks on the container instance that are in the RUNNING state are stopped and replaced
according the service's deployment configuration parameters, minimumHealthyPercent and
maximumPercent. Note that you can change the deployment configuration of your service using
UpdateService.
If minimumHealthyPercent is below 100%, the scheduler can ignore desiredCount
temporarily during task replacement. For example, desiredCount is four tasks, a minimum of 50%
allows the scheduler to stop two existing tasks before starting two new tasks. If the minimum is 100%, the
service scheduler can't remove existing tasks until the replacement tasks are considered healthy. Tasks for
services that do not use a load balancer are considered healthy if they are in the RUNNING state.
Tasks for services that use a load balancer are considered healthy if they are in the RUNNING state
and the container instance they are hosted on is reported as healthy by the load balancer.
The maximumPercent parameter represents an upper limit on the number of running tasks during task
replacement, which enables you to define the replacement batch size. For example, if desiredCount of
four tasks, a maximum of 200% starts four new tasks before stopping the four tasks to be drained (provided that
the cluster resources required to do this are available). If the maximum is 100%, then replacement tasks can't
start until the draining tasks have stopped.
Any PENDING or RUNNING tasks that do not belong to a service are not affected; you must
wait for them to finish or stop them manually.
A container instance has completed draining when it has no more RUNNING tasks. You can verify this
using ListTasks.
When you set a container instance to ACTIVE, the Amazon ECS scheduler can begin scheduling tasks on
the instance again.

Modifies the desired count, deployment configuration, or task definition used in a service.
You can add to or subtract from the number of instantiations of a task definition in a service by specifying the
cluster that the service is running in and a new desiredCount parameter.
You can use UpdateService to modify your task definition and deploy a new version of your service.
You can also update the deployment configuration of a service. When a deployment is triggered by updating the
task definition of a service, the service scheduler uses the deployment configuration parameters,
minimumHealthyPercent and maximumPercent, to determine the deployment strategy.
If minimumHealthyPercent is below 100%, the scheduler can ignore desiredCount
temporarily during a deployment. For example, if desiredCount is four tasks, a minimum of 50% allows
the scheduler to stop two existing tasks before starting two new tasks. Tasks for services that do not use a load
balancer are considered healthy if they are in the RUNNING state. Tasks for services that use a load
balancer are considered healthy if they are in the RUNNING state and the container instance they are
hosted on is reported as healthy by the load balancer.
The maximumPercent parameter represents an upper limit on the number of running tasks during a
deployment, which enables you to define the deployment batch size. For example, if desiredCount is
four tasks, a maximum of 200% starts four new tasks before stopping the four older tasks (provided that the
cluster resources required to do this are available).
When UpdateService stops a task during a deployment, the equivalent of docker stop is issued
to the containers running in the task. This results in a SIGTERM and a 30-second timeout, after
which SIGKILL is sent and the containers are forcibly stopped. If the container handles the
SIGTERM gracefully and exits within 30 seconds from receiving it, no SIGKILL is sent.
When the service scheduler launches new tasks, it determines task placement in your cluster with the following logic:
Determine which of the container instances in your cluster can support your service's task definition (for example, they have the required CPU, memory, ports, and container instance attributes).
By default, the service scheduler attempts to balance tasks across Availability Zones in this manner (although you can choose a different placement strategy):
Sort the valid container instances by the fewest number of running tasks for this service in the same Availability Zone as the instance. For example, if zone A has one running service task and zones B and C each have zero, valid container instances in either zone B or C are considered optimal for placement.
Place the new service task on a valid container instance in an optimal Availability Zone (based on the previous steps), favoring container instances with the fewest number of running tasks for this service.
When the service scheduler stops running tasks, it attempts to maintain balance across the Availability Zones in your cluster using the following logic:
Sort the container instances by the largest number of running tasks for this service in the same Availability Zone as the instance. For example, if zone A has one running service task and zones B and C each have two, container instances in either zone B or C are considered optimal for termination.
Stop the task on a container instance in an optimal Availability Zone (based on the previous steps), favoring container instances with the largest number of running tasks for this service.
