Docker Small Hints #4: Cleaning up your local zombie docker images
The following commands I found very useful to get rid of zombie docker objects/images, which are accumulated over testing time. If you don’t remove them from time to time, it can happen that your local docker environment runs out of space. Or you get some weird FileSystem errors during your docker build.
docker ps -a -q | xargs -n 1 docker rm
docker images -q --filter "dangling=true" | xargs docker rmi
docker images
