Docker quick ref :whale:

• Most used commands: docker ps, docker images, docker build, docker run

• Most used docker-run flags: -it interactive terminal, -d detached (in the background)

• Detach from running container: Ctrl P Q

• Remove all non-running images: docker rmi $(docker ps -aq) or docker image prune -a

• Check disk usage: docker system df

• Exec as specific user: docker exec -u root -it <containername>

• Run container with the same network namespace as another: docker run -it --network container:<containername> alpine
