AWS::ECS::DaemonTaskDefinition 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.

Syntax

To declare this entity in your CloudFormation template, use the following syntax:

JSON

{
  "Host" : HostVolumeProperties,
  "Name" : String
}

Properties

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.

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.
