There are more elegant ways to do this for Docker images and containers with the Docker Daemon 1.25+, but the Docker Daemon on Minikube (at time of writing, 0.25.0) is 1.23, so does not support these commands.

So for now, we can use these two gems from Jim Hoskin’s website to remove untagged images (failed builds mostly) and stopped containers.

Removing untagged images

docker image rm $(docker images | grep "^<none>" | awk "{print $3}")

Remove all stopped containers.

docker container rm $(docker ps -a -q)
