public interface AmazonECS
Interface for accessing Amazon ECS.

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.

  • Method Details

    • setEndpoint

      void setEndpoint(String endpoint)
      Overrides the default endpoint for this client ("https://ecs.us-east-1.amazonaws.com"). Callers can use this method to control which AWS region they want to work with.

      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.

      Parameters:
      endpoint - The endpoint (ex: "ecs.us-east-1.amazonaws.com") or a full URL, including the protocol (ex: "https://ecs.us-east-1.amazonaws.com") of the region specific AWS endpoint this client will communicate with.
    • setRegion

      void setRegion(Region region)
      An alternative to setEndpoint(String), sets the regional endpoint for this client's service calls. Callers can use this method to control which AWS region they want to work with.

      By default, all service endpoints in all regions use the https protocol. To use http instead, specify it in the ClientConfiguration supplied at construction.

      This method is not threadsafe. A region 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.

      Parameters:
      region - The region this client will communicate with. See Region.getRegion(com.amazonaws.regions.Regions) for accessing a given region. Must not be null and must be a region where the service is available.

    • createCluster

      CreateClusterResult createCluster(CreateClusterRequest createClusterRequest)

      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.

      Parameters:
      createClusterRequest -
      Returns:
      Result of the CreateCluster operation returned by the service.
      Throws:
      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 valid.
      InvalidParameterException - The specified parameter is invalid. Review the available parameters for the API request.
    • createCluster

      CreateClusterResult createCluster()
      Simplified method form for invoking the CreateCluster operation.
      See Also:
    • createService

      CreateServiceResult createService(CreateServiceRequest createServiceRequest)

      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.

      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.

      Parameters:
      createServiceRequest -
      Returns:
      Result of the CreateService operation returned by the service.
      Throws:
      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 valid.
      InvalidParameterException - The specified parameter is invalid. Review the available parameters for the API request.
      ClusterNotFoundException - The specified cluster could not be found. You can view your available clusters with ListClusters. Amazon ECS clusters are region-specific.
    • deleteCluster

      DeleteClusterResult deleteCluster(DeleteClusterRequest deleteClusterRequest)

      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.

      Parameters:
      deleteClusterRequest -
      Returns:
      Result of the DeleteCluster operation returned by the service.
      Throws:
      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 valid.
      InvalidParameterException - The specified parameter is invalid. Review the available parameters for the API request.
      ClusterNotFoundException - The specified cluster could not be found. You can view your available clusters with ListClusters. 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 DeleteService.
    • deleteService

      DeleteServiceResult deleteService(DeleteServiceRequest deleteServiceRequest)

      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.

      Parameters:
      deleteServiceRequest -
      Returns:
      Result of the DeleteService operation returned by the service.
      Throws:
      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 valid.
      InvalidParameterException - The specified parameter is invalid. Review the available parameters for the API request.
      ClusterNotFoundException - The specified cluster could not be found. You can view your available clusters with ListClusters. Amazon ECS clusters are region-specific.
      ServiceNotFoundException - The specified service could not be found. You can view your available services with ListServices. Amazon ECS services are cluster-specific and region-specific.
    • deregisterContainerInstance

      DeregisterContainerInstanceResult deregisterContainerInstance(DeregisterContainerInstanceRequest deregisterContainerInstanceRequest)

      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).

      Parameters:
      deregisterContainerInstanceRequest -
      Returns:
      Result of the DeregisterContainerInstance operation returned by the service.
      Throws:
      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 valid.
      InvalidParameterException - The specified parameter is invalid. Review the available parameters for the API request.
      ClusterNotFoundException - The specified cluster could not be found. You can view your available clusters with ListClusters. Amazon ECS clusters are region-specific.
    • deregisterTaskDefinition

      DeregisterTaskDefinitionResult deregisterTaskDefinition(DeregisterTaskDefinitionRequest deregisterTaskDefinitionRequest)

      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).

      Parameters:
      deregisterTaskDefinitionRequest -
      Returns:
      Result of the DeregisterTaskDefinition operation returned by the service.
      Throws:
      ServerException - These errors are usually caused by a server issue.

    • updateContainerAgent

      UpdateContainerAgentResult updateContainerAgent(UpdateContainerAgentRequest updateContainerAgentRequest)

      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.

      Parameters:
      updateContainerAgentRequest -
      Returns:
      Result of the UpdateContainerAgent operation returned by the service.
      Throws:
      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 valid.
      InvalidParameterException - The specified parameter is invalid. Review the available parameters for the API request.
      ClusterNotFoundException - The specified cluster could not be found. You can view your available clusters with ListClusters. Amazon ECS clusters are region-specific.
      UpdateInProgressException - There is already a current Amazon ECS container agent update in progress on the specified container instance. If the container agent becomes disconnected while it is in a transitional stage, such as 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 instance and does not have enough information to proceed with an update. This could be because the agent running on the container instance is an older or custom version that does not use our version information.
    • updateService

      UpdateServiceResult updateService(UpdateServiceRequest updateServiceRequest)

      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.

      Parameters:
      updateServiceRequest -
      Returns:
      Result of the UpdateService operation returned by the service.
      Throws:
      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 valid.
      InvalidParameterException - The specified parameter is invalid. Review the available parameters for the API request.
      ClusterNotFoundException - The specified cluster could not be found. You can view your available clusters with ListClusters. Amazon ECS clusters are region-specific.
      ServiceNotFoundException - The specified service could not be found. You can view your available services with ListServices. Amazon ECS services are cluster-specific and region-specific.
      ServiceNotActiveException - The specified service is not active. You cannot update a service that is not active. If you have previously deleted a service, you can re-create it with CreateService.
    • shutdown

      void shutdown()
      Shuts down this client object, releasing any resources that might be held open. This is an optional method, and callers are not expected to call it, but can if they want to explicitly release any open resources. Once a client has been shutdown, it should not be used to make any more requests.
    • getCachedResponseMetadata

      ResponseMetadata getCachedResponseMetadata(AmazonWebServiceRequest request)
      Returns additional metadata for a previously executed successful request, typically used for debugging issues where a service isn't acting as expected. This data isn't considered part of the result data returned by an operation, so it's available through this separate, diagnostic interface.

      Response metadata is only cached for a limited period of time, so if you need to access this extra diagnostic information for an executed request, you should use this method to retrieve it as soon as possible after executing a request.

      Parameters:
      request - The originally executed request.
      Returns:
      The response metadata for the specified request, or null if none is available.
