This Bash script provides a quick overview of the sizes of Docker volumes using the du (disk usage) command. It iterates through all Docker volumes, retrieves their mountpoints, and calculates and prints their sizes in a human-readable format. Useful for monitoring and managing disk usage in Docker environments.

#!/bin/bash

# Get a list of all Docker volume names
volume_names=$(docker volume ls --quiet)

# Iterate through each volume and print its name and size
for volume_name in $volume_names; do
    volume_path=$(docker volume inspect --format '{{ .Mountpoint }}' $volume_name)
    volume_size=$(du -sh $volume_path | cut -f1)
    echo "Volume: $volume_name, Size: $volume_size"
