-====== Docker - Remove a volume ======
-===== Remove one or more specific volumes - Docker 1.9 and later =====
-Use the **docker volume ls** command to locate the volume name or names you wish to delete.
-Then you can remove one or more volumes with the **docker volume rm** command:
-To list the volumes:
-<code bash>
-docker volume ls
-</code>
-To remove the volumes:
-<code bash>
-docker volume rm volume_name volume_name
-</code>

-===== Remove dangling volumes - Docker 1.9 and later =====
-Since the point of volumes is to exist independent from containers, when a container is removed, a volume is not automatically removed at the same time.
-When a volume exists and is no longer connected to any containers, however, it's called a dangling volume.
-To locate them to confirm you want to remove them, you can use the **docker volume ls** command with a filter to limit the results to dangling volumes.
-When you're satisfied with the list, you can add a **-q** flag to provide the volume name to **docker volume rm**:
-To list the volumes:
-<code bash>
-docker volume ls -f dangling=true
-</code>
-To remove the volumes:
-<code bash>
-docker volume rm $(docker volume ls -f dangling=true -q)
-</code>
-----
-===== Remove a container and its volume =====
-If you created an unnamed volume, it can be deleted at the same time as the container with the **-v** flag.
-Note that this only works with unnamed volumes.
-When the container is successfully removed, its ID is displayed.
-Note that no reference is made to the removal of the volume.
-If it is unnamed, it is silently removed from the system.
-If it is named, it silently stays present.
-To remove:
-<code bash>
-docker rm -v container_name
