Docker How To Clear Cache

You can clear the cache with the following:

docker kill $(docker ps -q)
docker rm $(docker ps -aq)
docker rmi $(docker images -a -q)

You might only want to clear out unused stuff:

docker image prune -a -f

Alternative Method to Clear Cache

Stop the docker service:

systemctl stop docker 

Wipe out all of these files:

rm -rf /var/lib/docker/*

Start Docker back up:

systemctl start docker
