      public final String capacityProviderName()

      The capacity provider that's associated with the container instance.

      Returns:
      The capacity provider that's associated with the container instance.

    • version

      public final Long version()

      The version counter for the container instance. Every time a container instance experiences a change that triggers a CloudWatch event, the version counter is incremented. If you're replicating your Amazon ECS container instance state with CloudWatch Events, you can compare the version of a container instance reported by the Amazon ECS APIs with the version reported in CloudWatch Events for the container instance (inside the detail object) to verify that the version in your event stream is current.

      Returns:
      The version counter for the container instance. Every time a container instance experiences a change that triggers a CloudWatch event, the version counter is incremented.

    • versionInfo

      public final VersionInfo versionInfo()

      The version information for the Amazon ECS container agent and Docker daemon running on the container instance.

      Returns:
      The version information for the Amazon ECS container agent and Docker daemon running on the container instance.

    • hasRemainingResources

      public final boolean hasRemainingResources()
      For responses, this returns true if the service returned a value for the RemainingResources 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.

    • remainingResources

      public final List<Resource> remainingResources()

      For CPU and memory resource types, this parameter describes the remaining CPU and memory that wasn't already allocated to tasks and is therefore available for new tasks. For port resource types, this parameter describes the ports that were reserved by the Amazon ECS container agent (at instance registration time) and any task containers that have reserved port mappings on the host (with the host or bridge network mode). Any port that's not specified here is available for new tasks.

      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 hasRemainingResources() method.

      Returns:

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.

    • registeredResources

      public final List<Resource> registeredResources()

      For CPU and memory resource types, this parameter describes the amount of each resource that was available on the container instance when the container agent registered it with Amazon ECS. This value represents the total amount of CPU and memory that can be allocated on this container instance to tasks. For port resource types, this parameter describes the ports that were reserved by the Amazon ECS container agent when it registered the container instance with Amazon ECS.

      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 hasRegisteredResources() method.

    • status

      public final String status()

      The status of the container instance. The valid values are REGISTERING, REGISTRATION_FAILED, ACTIVE, INACTIVE, DEREGISTERING, or DRAINING.

      If your account has opted in to the awsvpcTrunking account setting, then any newly registered container instance will transition to a REGISTERING status while the trunk elastic network interface is provisioned for the instance. If the registration fails, the instance will transition to a REGISTRATION_FAILED status. You can describe the container instance and see the reason for failure in the statusReason parameter. Once the container instance is terminated, the instance transitions to a DEREGISTERING status while the trunk elastic network interface is deprovisioned. The instance then transitions to an INACTIVE status.

      The ACTIVE status indicates that the container instance can accept tasks. The DRAINING indicates that new tasks aren't placed on the container instance and any service tasks running on the container instance are removed if possible. For more information, see Container instance draining in the Amazon Elastic Container Service Developer Guide.

      Returns:
      The status of the container instance. The valid values are REGISTERING, REGISTRATION_FAILED, ACTIVE, INACTIVE, DEREGISTERING, or DRAINING.

      • 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.
