<p>
The contents of the <code>host</code> parameter determine whether your data 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.

<p>
This parameter isn't applicable to jobs that are running on Fargate resources and shouldn't be provided.
