public void setEndpoint(String endpoint)
AmazonECS
Callers can pass in just the endpoint (ex: "ecs.us-east-1.amazonaws.com")
or a full URL, including the protocol (ex:
"https://ecs.us-east-1.amazonaws.com"). If the protocol is not specified
here, the default protocol from this client's ClientConfiguration
will be used, which by default is HTTPS.
For more information on using AWS regions with the AWS SDK for Java, and a complete list of all available endpoints for all AWS services, see: http://developer.amazonwebservices.com/connect/entry.jspa?externalID= 3912
This method is not threadsafe. An endpoint should be configured when the client is created and before any service requests are made. Changing it afterwards creates inevitable race conditions for any service requests in transit or retrying.

public CreateClusterResult createCluster(CreateClusterRequest request)
AmazonECS
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.
createCluster
in interface AmazonECS
public CreateClusterResult createCluster()
AmazonECS
createCluster
in interface AmazonECS
AmazonECS.createCluster(CreateClusterRequest)
public CreateServiceResult createService(CreateServiceRequest request)
AmazonECS
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 instantiation 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
of a service with an UpdateService operation), the service
scheduler uses the minimumHealthyPercent
and
maximumPercent
parameters to determine the deployment
strategy.
If the minimumHealthyPercent
is below 100%, the scheduler
can ignore the desiredCount
temporarily during a deployment.
For example, if your service has a desiredCount
of four
tasks, a minimumHealthyPercent
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
do use a load balancer are considered healthy if they are in the
RUNNING
state and the container instance it is 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 running tasks during a deployment, which enables you to
define the deployment batch size. For example, if your service has a
desiredCount
of four tasks, a maximumPercent
value of 200% starts 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 attempts to balance them across the Availability Zones 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).
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.
createService
in interface AmazonECS
public DeleteClusterResult deleteCluster(DeleteClusterRequest request)
AmazonECS
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.
deleteCluster
in interface AmazonECS
public DeleteServiceResult deleteService(DeleteServiceRequest request)
AmazonECS
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.
deleteService
in interface AmazonECS
public DeregisterContainerInstanceResult deregisterContainerInstance(DeregisterContainerInstanceRequest request)
AmazonECS
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 with a connected Amazon ECS container agent, the agent automatically deregisters the instance from your cluster (stopped container instances or instances with disconnected agents are not automatically deregistered when terminated).
deregisterContainerInstance
in interface AmazonECS
public DeregisterTaskDefinitionResult deregisterTaskDefinition(DeregisterTaskDefinitionRequest request)
AmazonECS
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).

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

public RunTaskResult runTask(RunTaskRequest request)
AmazonECS
Start a task using random placement and the default Amazon ECS scheduler.
To use your own scheduler or place a task on a specific container
instance, use StartTask
instead.
The count
parameter is limited to 10 tasks per call.
public StartTaskResult startTask(StartTaskRequest request)
AmazonECS
Starts a new task from the specified task definition on the specified
container instance or instances. To use the default Amazon ECS scheduler
to place your task, use RunTask
instead.
The list of container instances to start tasks on is limited to 10.
public StopTaskResult stopTask(StopTaskRequest request)
AmazonECS
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 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.

public UpdateContainerAgentResult updateContainerAgent(UpdateContainerAgentRequest request)
AmazonECS
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.
updateContainerAgent
in interface AmazonECS
public UpdateServiceResult updateService(UpdateServiceRequest request)
AmazonECS
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 the minimumHealthyPercent
is below 100%, the scheduler
can ignore the desiredCount
temporarily during a deployment.
For example, if your service has a desiredCount
of four
tasks, a minimumHealthyPercent
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
do use a load balancer are considered healthy if they are in the
RUNNING
state and the container instance it is 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 your service has a
desiredCount
of four tasks, a maximumPercent
value 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 attempts to balance them across the Availability Zones 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).
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.
