Common Commands

Stop All Docker Containers

docker kill $(docker ps -q)

The docker ps command will list all running containers. The -q flag will only list the IDs for those containers. Once we have the list of all container IDs, we can simply run the docker kill command, passing all those IDs, and they’ll all be stopped!

Remove All Docker Containers

docker rm $(docker ps -a -q)

We already know that docker ps -q will list all running container IDs. What is the -a flag? Well that will return all containers, not just the running ones. Therefore, this comman will remove all containers (including both running and stopped containers).

Remove All Docker Images

docker rmi $(docker images -q)

docker images -q will list all image IDs. We pass these IDs to docker rmi (which stands for remove images) and we therefore remove all the images.
