AWS::ECS::TaskDefinition Volume - AWS CloudFormation

AWS::ECS::TaskDefinition Volume

The Volume property specifies a data volume used in a task definition. For tasks that use a Docker volume, specify a DockerVolumeConfiguration. For tasks that use a bind mount host volume, specify a host and optional sourcePath. For more information, see Using Data Volumes in Tasks.


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



This parameter is specified when you are using Docker volumes.

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

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

This parameter is specified when you are using 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 is stored. If the host parameter is empty, then the Docker daemon assigns a host path for your data volume. However, the data is not guaranteed to persist after the containers associated with it stop running.

Windows containers can mount whole directories on the same drive as $env:ProgramData. Windows containers cannot mount directories on a different drive, and mount point cannot 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.
