help

docker container --help

Enter container

• start a new container and enter it:

  docker container run -it <container> bash

  If we exit it, container stops

• enter a running container:

  docker container exec -it <container> bash

  If we exit it, container still runs

One more useful tag: --rm. It causes Docker to automatically remove the container when it exits.
