The Applications > Volumes pane lists all the volumes created and mounted by Docker containers. A volume is form of a persistent storage that is attached to by a Docker container’s application, as to store the application’s data. A Docker container’s application that exists in multiple marketplace catalogs can share the same volume. When a Docker container is stopped and removed, its volume is not removed automatically and must be removed manually.

To remove a volume, navigate to Applications > Volumes, select the check box for the volume, and click the Remove Selected icon.
