How To Install and Use Docker on Ubuntu 16.04 (very well explained + provides interesting details + it works)

Installing Wharfer on one of the AD machines

TODO(Niklas): bitte korrigieren / ergänzen

sudo vim /etc/docker/daemon.json -> user namespace eintrage (TODO: was konkret?)
https://github.com/ad-freiburg/docker-no-trivial-root#building (TODO: genau welche Abschnitte?)
git clone <wharfer-binary> (TODO: wo hin kopieren?)

Docker Troubleshooting

"docker: Got permission denied while trying to connect" or "ERROR: Couldn't connect to Docker daemon" (2018-01-19)

WARNING: This is defacto equivalent to root access

We're currently working on two solutions that combined should in the future be relatively safe. These are wharfer and docker-no-trivial-root

Add user to group docker and switch to that group:

sudo usermod -aG docker <username>
# Logout
# Login
newgrp docker
