If this value is true, the Docker volume is created if it doesn't already exist.

The Docker volume driver to use. The driver value must match the driver name provided by Docker because it is used for task placement. If the driver was installed using the Docker plugin CLI, use docker plugin ls to retrieve the driver name from your container instance. If the driver was installed using another method, use Docker plugin discovery to retrieve the driver name. This parameter maps to Driver in the docker container create command and the xxdriver option to docker volume create.

A map of Docker driver-specific options passed through. This parameter maps to DriverOpts in the docker create-volume command and the xxopt option to docker volume create.

Custom metadata to add to your Docker volume. This parameter maps to Labels in the docker container create command and the xxlabel option to docker volume create.

The scope for the Docker volume that determines its lifecycle. Docker volumes that are scoped to a task are automatically provisioned when the task starts and destroyed when the task stops. Docker volumes that are scoped as shared persist after the task stops.
