Handy for some quick testing.
Debian
docker run -it debian /bin/bash
Alpine

Hostname of the host
When you are inside a docker container, you can use host.docker.internal for connections to the host machine.
Stop all running containers
docker stop $(docker ps -q)
Remove containers
Remove all stopped containers
docker rm $(docker ps -aq)
Remove all stopped and running containers
docker rm -f $(docker ps -aq)
Docker System Prune
Clean up your host a bit.
docker system prune
Remove all Images
This is not done by docker system prune and gives your host machine some free space.
docker rmi $(docker images -q)
Remove all volumes
This is also not done by docker system prune.
docker volume rm $(docker volume ls -q)
