Angelehnt an [https://www.laub-home.de/wiki/Docker_Volume_Rename_-_HowTo|Andread Laub] (in German).
The current docker volume-command has no rename option. This article shows how you can circumvent this restriction to rename a volume anyway. More correctly it copies the contents from one volume to new, correctly named volume and then deletes the old.
Copy the clone-docker-volumes script from alaub's Github.
wget https://raw.githubusercontent.com/alaub81/scripts/master/clone-docker-volumes.sh chmod +x clone-docker-volumes.sh
this command shows current volumes
docker volume ls # creates Volume_NEW and copies Volume_OLD to Volume_NEW clone-docker-volumes.sh volume_OLD volume_NEW
Cleaning up afterwards:
First command shows all volumes that are not assigned to a container.
docker volume ls -f dangling=true docker volume rm volume_ALT
Done!
