Cleanup Docker

If you are running docker you will accumulate a lot of unused images and volumes as you update running containers. This makes maintenance a necessity.

Running Docker? Be sure and cleanup unused images and volumes with:
docker volume rm $(docker volume ls -f dangling=true -q)
docker rmi $(docker images --quiet --filter "dangling=true")

Do you need this?

Check your portainer status page and look for “unused” images and containers. If you are seeing a lot of these, then you are wasting space and I’d recommend running this script to clean them up!

The Cleanup Script

Run this bash script every week to ensure the cleanup gets performed.

#!/bin/bash

docker volume rm $(docker volume ls -f dangling=true -q)
docker rmi $(docker images --quiet --filter "dangling=true")
