How to determine what containers use the docker volume?

The script below will show each volume with the container(s) using it:

#!/bin/sh

volumes=$(docker volume ls  --format '{{.Name}}')

for volume in $volumes
do
  echo $volume
  docker ps -a --filter volume="$volume"  --format '{{.Names}}' | sed 's/^/  /'
done

Listing volumes by container is slightly trickier so it's an exercise for the reader but the above should suffice unless you have many containers/volumes.

docker ps can filter by volume to show all of the containers that mount a given volume:

docker ps -a --filter volume=VOLUME_NAME_OR_MOUNT_POINT
