Docker Volume - Remove, Prune
To remove the volumes, we can use the rm option.
Listing all the volume that are available right now-
gaurav@learning-ocean:~$ docker volume ls
DRIVER VOLUME NAME
local abc
local mytest
local mytest1
local mytest2
local mytest3
local mytest4
gaurav@learning-ocean:~$
Now, lets delete mytest, mytest1, mytest2 volumes-
gaurav@learning-ocean:~$ docker volume rm mytest
mytest
gaurav@learning-ocean:~$ docker volume rm mytest1 mytest2
mytest1
mytest2
gaurav@learning-ocean:~$
We have only 3 volumes left now-
gaurav@learning-ocean:~$ docker volume ls
DRIVER VOLUME NAME
local abc
local mytest3
local mytest4
gaurav@learning-ocean:~$
Now, to remove all the unused volumes, we can use prune command -
gaurav@learning-ocean:~$ docker volume prune
WARNING! This will remove all local volumes not used by at least one container.
Are you sure you want to continue? [y/N] y
Deleted Volumes:
mytest3
mytest4
Total reclaimed space: 0B
gaurav@learning-ocean:~$
The above command only deleted mytest3 and mytest4 and not the abc volume because it is still associated with a container.
gaurav@learning-ocean:~$ docker container ls
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES

gaurav@learning-ocean:~$ docker volume ls
DRIVER VOLUME NAME
local abc
To remove the volume above we first have to remove it then only we will be able to delete the volume-
gaurav@learning-ocean:~$ docker container rm -f 9f
9f
Now we can delete the abc volume as it is in unused state now using prune command -
gaurav@learning-ocean:~$ docker volume prune
