Class Volume

  • All Implemented Interfaces:
    Serializable, SdkPojo, ToCopyableBuilder<Volume.Builder,​Volume>
    @Generated("software.amazon.awssdk:codegen")
public final class Volume
extends Object
implements SdkPojo, Serializable, ToCopyableBuilder<Volume.Builder,​Volume>

    The data volume configuration for tasks launched using this task definition. Specifying a volume configuration in a task definition is optional. The volume configuration may contain multiple volumes but only one volume configured at launch is supported. Each volume defined in the volume configuration may only specify a name and one of either configuredAtLaunch, dockerVolumeConfiguration, efsVolumeConfiguration, fsxWindowsFileServerVolumeConfiguration, or host. If an empty volume configuration is specified, by default Amazon ECS uses a host volume. For more information, see Using data volumes in tasks.

    • Method Detail

      • name

        public final String name()

        The name of the volume. Up to 255 letters (uppercase and lowercase), numbers, underscores, and hyphens are allowed.

        When using a volume configured at launch, the name is required and must also be specified as the volume name in the ServiceVolumeConfiguration or TaskVolumeConfiguration parameter when creating your service or standalone task.

        For all other types of volumes, this name is referenced in the sourceVolume parameter of the mountPoints object in the container definition.

        When a volume is using the efsVolumeConfiguration, the name is required.

        Returns:
        The name of the volume. Up to 255 letters (uppercase and lowercase), numbers, underscores, and hyphens are allowed.

        When a volume is using the efsVolumeConfiguration, the name is required.

      • host

        public final HostVolumeProperties host()

        This parameter is specified when you use bind mount host volumes. The contents of the host parameter determine whether your bind mount host volume persists on the host container instance and where it's stored. If the host parameter is empty, then the Docker daemon assigns a host path for your data volume. However, the data isn't guaranteed to persist after the containers that are associated with it stop running.

        Windows containers can mount whole directories on the same drive as $env:ProgramData. Windows containers can't mount directories on a different drive, and mount point can't be across drives. For example, you can mount C:\my\path:C:\my\path and D:\:D:\, but not D:\my\path:C:\my\path or D:\:C:\my\path.

      • dockerVolumeConfiguration

        public final DockerVolumeConfiguration dockerVolumeConfiguration()

        This parameter is specified when you use Docker volumes.

        Windows containers only support the use of the local driver. To use bind mounts, specify the host parameter instead.

        Docker volumes aren't supported by tasks run on Fargate.

        Returns:

      • efsVolumeConfiguration

        public final EFSVolumeConfiguration efsVolumeConfiguration()

        This parameter is specified when you use an Amazon Elastic File System file system for task storage.

        Returns:
        This parameter is specified when you use an Amazon Elastic File System file system for task storage.

      • fsxWindowsFileServerVolumeConfiguration

        public final FSxWindowsFileServerVolumeConfiguration fsxWindowsFileServerVolumeConfiguration()

        This parameter is specified when you use Amazon FSx for Windows File Server file system for task storage.

        Returns:
        This parameter is specified when you use Amazon FSx for Windows File Server file system for task storage.

      • configuredAtLaunch

        public final Boolean configuredAtLaunch()

        Indicates whether the volume should be configured at launch time. This is used to create Amazon EBS volumes for standalone tasks or tasks created as part of a service. Each task definition revision may only have one volume configured at launch in the volume configuration.

        To configure a volume at launch time, use this task definition revision and specify a volumeConfigurations object when calling the CreateService, UpdateService, RunTask or StartTask APIs.
