Dangling Volumes

A dangling volume is a volume that's no longer associated with any container. While the container is gone, the volume remains on the host's disk, consuming space.

To list all dangling volumes, use the following filter:

docker volume ls -f dangling=true

To calculate the total size of these volumes, we can use a script.

total_size=0

# Loop through each dangling volume ID
for volume in $(docker volume ls -qf dangling=true); do
    # Get the host mountpoint of the volume
    mountpoint=$(docker volume inspect "$volume" --format '{{ .Mountpoint }}')

    # Calculate the size in Kilobytes (k)
    # 2>/dev/null handles cases where the path might be inaccessible
    size=$(sudo du -sk "$mountpoint" 2>/dev/null | cut -f1)
