    • serviceName

      public final String serviceName()

      The name of your service. Up to 255 letters (uppercase and lowercase), numbers, underscores, and hyphens are allowed. Service names must be unique within a cluster, but you can have similarly named services in multiple clusters within a Region or across multiple Regions.

      Returns:
      The name of your service. Up to 255 letters (uppercase and lowercase), numbers, underscores, and hyphens are allowed. Service names must be unique within a cluster, but you can have similarly named services in multiple clusters within a Region or across multiple Regions.

    • taskDefinition

      public final String taskDefinition()

      The family and revision (family:revision) or full ARN of the task definition to run in your service. If a revision isn't specified, the latest ACTIVE revision is used.

      A task definition must be specified if the service uses either the ECS or CODE_DEPLOY deployment controllers.

      For more information about deployment types, see Amazon ECS deployment types.

      Returns:
      The family and revision (family:revision) or full ARN of the task definition to run in your service. If a revision isn't specified, the latest ACTIVE revision is used.

      A task definition must be specified if the service uses either the ECS or CODE_DEPLOY deployment controllers.

      For more information about deployment types, see Amazon ECS deployment types.

    • availabilityZoneRebalancing

      public final AvailabilityZoneRebalancing availabilityZoneRebalancing()

      Indicates whether to use Availability Zone rebalancing for the service.

      For more information, see Balancing an Amazon ECS service across Availability Zones in the Amazon Elastic Container Service Developer Guide .

      The default behavior of AvailabilityZoneRebalancing differs between create and update requests:

      • For create service requests, when no value is specified for AvailabilityZoneRebalancing, Amazon ECS defaults the value to ENABLED.

      • For update service requests, when no value is specified for AvailabilityZoneRebalancing, Amazon ECS defaults to the existing service’s AvailabilityZoneRebalancing value. If the service never had an AvailabilityZoneRebalancing value set, Amazon ECS treats this as DISABLED.

      If the service returns an enum value that is not available in the current SDK version, availabilityZoneRebalancing will return AvailabilityZoneRebalancing.UNKNOWN_TO_SDK_VERSION. The raw value returned by the service is available from availabilityZoneRebalancingAsString().

      Returns:
      Indicates whether to use Availability Zone rebalancing for the service.

    • hasLoadBalancers

      public final boolean hasLoadBalancers()
      For responses, this returns true if the service returned a value for the LoadBalancers property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.

    • loadBalancers

      public final List<LoadBalancer> loadBalancers()

      A load balancer object representing the load balancers to use with your service. For more information, see Service load balancing in the Amazon Elastic Container Service Developer Guide.

      If the service uses the ECS deployment controller and using either an Application Load Balancer or Network Load Balancer, you must specify one or more target group ARNs to attach to the service. The service-linked role is required for services that use multiple target groups. For more information, see Using service-linked roles for Amazon ECS in the Amazon Elastic Container Service Developer Guide.

      If the service uses the CODE_DEPLOY deployment controller, the service is required to use either an Application Load Balancer or Network Load Balancer. When creating an CodeDeploy deployment group, you specify two target groups (referred to as a targetGroupPair). During a deployment, CodeDeploy determines which task set in your service has the status PRIMARY, and it associates one target group with it. Then, it also associates the other target group with the replacement task set. The load balancer can also have up to two listeners: a required listener for production traffic and an optional listener that you can use to perform validation tests with Lambda functions before routing production traffic to it.

      If you use the CODE_DEPLOY deployment controller, these values can be changed when updating the service.

      For Application Load Balancers and Network Load Balancers, this object must contain the load balancer target group ARN, the container name, and the container port to access from the load balancer. The container name must be as it appears in a container definition. The load balancer name parameter must be omitted. When a task from this service is placed on a container instance, the container instance and port combination is registered as a target in the target group that's specified here.

      For Classic Load Balancers, this object must contain the load balancer name, the container name , and the container port to access from the load balancer. The container name must be as it appears in a container definition. The target group ARN parameter must be omitted. When a task from this service is placed on a container instance, the container instance is registered with the load balancer that's specified here.

      Services with tasks that use the awsvpc network mode (for example, those with the Fargate launch type) only support Application Load Balancers and Network Load Balancers. Classic Load Balancers aren't supported. Also, when you create any target groups for these services, you must choose ip as the target type, not instance. This is because tasks that use the awsvpc network mode are associated with an elastic network interface, not an Amazon EC2 instance.

      Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.

      This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasLoadBalancers() method.

      Returns:
      A load balancer object representing the load balancers to use with your service. For more information, see Service load balancing in the Amazon Elastic Container Service Developer Guide.

      If the service uses the ECS deployment controller and using either an Application Load Balancer or Network Load Balancer, you must specify one or more target group ARNs to attach to the service.

    • hasServiceRegistries

      public final boolean hasServiceRegistries()
      For responses, this returns true if the service returned a value for the ServiceRegistries property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.

    • serviceRegistries

      public final List<ServiceRegistry> serviceRegistries()

      The details of the service discovery registry to associate with this service. For more information, see Service discovery.

      Each service may be associated with one service registry. Multiple service registries for each service isn't supported.

      Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.

      This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasServiceRegistries() method.

      Returns:
      The details of the service discovery registry to associate with this service. For more information, see Service discovery.

    • launchType

      public final LaunchType launchType()

      The infrastructure that you run your service on. For more information, see Amazon ECS launch types in the Amazon Elastic Container Service Developer Guide.

      If you want to use Amazon ECS Managed Instances, you must use the capacityProviderStrategy request parameter and omit the launchType request parameter.

      The FARGATE launch type runs your tasks on Fargate On-Demand infrastructure.

      Fargate Spot infrastructure is available for use but a capacity provider strategy must be used. For more information, see Fargate capacity providers in the Amazon ECS Developer Guide.

    • schedulingStrategy

      public final SchedulingStrategy schedulingStrategy()

      The scheduling strategy to use for the service. For more information, see Services.

      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. This scheduler strategy is required if the service uses the CODE_DEPLOY or EXTERNAL deployment controller types.

      • 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 don't meet the placement constraints. When you're using this strategy, you don't need to specify a desired number of tasks, a task placement strategy, or use Service Auto Scaling policies.

        Tasks using the Fargate launch type or the CODE_DEPLOY or EXTERNAL deployment controller types don't support the DAEMON scheduling strategy.

      If the service returns an enum value that is not available in the current SDK version, schedulingStrategy will return SchedulingStrategy.UNKNOWN_TO_SDK_VERSION. The raw value returned by the service is available from schedulingStrategyAsString().

      The scheduling strategy to use for the service. For more information, see Services.

      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. This scheduler strategy is required if the service uses the CODE_DEPLOY or EXTERNAL deployment controller types.

      • 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 don't meet the placement constraints. When you're using this strategy, you don't need to specify a desired number of tasks, a task placement strategy, or use Service Auto Scaling policies.

        Tasks using the Fargate launch type or the CODE_DEPLOY or EXTERNAL deployment controller types don't support the DAEMON scheduling strategy.

    • deploymentController

      public final DeploymentController deploymentController()

      The deployment controller to use for the service. If no deployment controller is specified, the default value of ECS is used.

      Returns:
      The deployment controller to use for the service. If no deployment controller is specified, the default value of ECS is used.

    • hasTags

      public final boolean hasTags()
      For responses, this returns true if the service returned a value for the Tags property. This DOES NOT check that the value is non-empty (for which, you should check the isEmpty() method on the property). This is useful because the SDK will never return a null collection or map, but you may need to differentiate between the service returning nothing (or null) and the service returning an empty collection or map. For requests, this returns true if a value for the property was specified in the request builder, and false if a value was not specified.

    • tags

      public final List<Tag> tags()

      The metadata that you apply to the service to help you categorize and organize them. Each tag consists of a key and an optional value, both of which you define. When a service is deleted, the tags are deleted as well.

      The following basic restrictions apply to tags:

      • Maximum number of tags per resource - 50

      • For each resource, each tag key must be unique, and each tag key can have only one value.

      • Maximum key length - 128 Unicode characters in UTF-8

      • Maximum value length - 256 Unicode characters in UTF-8

      • If your tagging schema is used across multiple services and resources, remember that other services may have restrictions on allowed characters. Generally allowed characters are: letters, numbers, and spaces representable in UTF-8, and the following characters: + - = . _ : / @.

      • Tag keys and values are case-sensitive.

      • Do not use aws:, AWS:, or any upper or lowercase combination of such as a prefix for either keys or values as it is reserved for Amazon Web Services use. You cannot edit or delete tag keys or values with this prefix. Tags with this prefix do not count against your tags per resource limit.

      Attempts to modify the collection returned by this method will result in an UnsupportedOperationException.

      This method will never return null. If you would like to know whether the service returned this field (so that you can differentiate between null and empty), you can use the hasTags() method.

      Returns:
      Specifies whether to turn on Amazon ECS managed tags for the tasks within the service. For more information, see Tagging your Amazon ECS resources in the Amazon Elastic Container Service Developer Guide.

      When you use Amazon ECS managed tags, you must set the propagateTags request parameter.

    • propagateTags

      public final PropagateTags propagateTags()

      Specifies whether to propagate the tags from the task definition to the task. If no value is specified, the tags aren't propagated. Tags can only be propagated to the task during task creation. To add tags to a task after task creation, use the TagResource API action.
