The Applications > Volumes pane lists all volumes where the marketplace applications are deployed. A volume is a persistent storage that can be attached with an application installed in a container-based environment. An application that exists in multiple marketplaces can use the same volume. When a container is deleted, its volume is not deleted automatically. In this case, you may want to delete the volume as well.

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