I have added the tip, as mentioned in https://techan.fr/docker-chasse-a-lespace-perdu-gare-aux-volumes.html and used by @yjacolin for customers that recently had disk space issues. I have no clue if both commands do the same thing.
@yjacolin what do you think? Have customers used the prune command as well?

For last release of Docker you can use::
docker system prune --volumes
or::
docker system prune --all

Jenkins has finally passed. I will merge the PR soon if no one objects in the meantime. |
This PR adds instructions to remove "ghost" volumes, as described at https://techan.fr/docker-chasse-a-lespace-perdu-gare-aux-volumes.html > "Les volumes “fantômes”", pointed by @yjacolin
By the way I have dropped a reference to ExtJS in the documentation opening page :P
