Recently I started using Docker in my internship and sometimes you just mess up your docker images and containers, so you wanted to start from clean but first you need to remove all images and containers of Docker locally.
# Delete all Docker containers docker rm -f $(docker ps -a -q) # Delete all Docker images docker rmi -f $(docker images -q)
Also there is a new docker command, that will delete all unused images and volumes.
docker system prune --all --force
