Before a while I got in touch with the wonderful world of the Docker (see https://www.docker.com) cosmos. I think it is one of the most important virtualisation technology at the moment.

On this page I will just collect useful commands that helped me a lot in my daily work with Docker, Docker-Compose (https://docs.docker.com/compose/) and other stack related tools such AWS Docker registries. Additionally I will continuously collect useful links, that helped me to get along in the wide field of docker.

Useful Docker commands:

• run an  arbitrary Docker image (available on Dockerhub) and open a shell into the launched machine:
  $> docker run -i -t python:3.5.1 /bin/bash
  or an alpine based one:
  $> docker run -i -t python:3.6.5-alpine3.7 /bin/ash
• list all running containers
  $> docker ps
• mount folder into a container to have access to the files in the current folder:
  $> docker run -v $PWD:/path/inside/docker/container -i -t python:3.6.5-alpine3.7 /bin/as
• or a file (overrides existing targets f.e. if you want to replace a configuration file at runtime that was created during buildtime of the container image)
  $> docker run -v $(pwd)/test/deploy_conf.yml:/app/config/deploy_conf.yml -i -t mina:test /bin/ash
• list all orphaned volumes (not used by any container anymore):

  $> docker volume ls -f dangling=true

• remove a single image:

  $> docker volume rm VOLUMENAME

• remove all orphaned volumes at once:

  $> docker volume ls -qf dangling=true | xargs --no-run-if-empty docker volume rm

• t.b.c

Useful Docker shortcuts:

I placed these shortcuts inside my .bash_alias file under Linux, so that I have autocomplete / suggests:
