Notes

• Internally, hosts resolve through their docker names, i.e. salt-master, controller01, compute01.
• Environment configured both over IPv4 and IPv6
• Images fsoppelsa/saltmaster and fsoppelsa/saltminion are pushed to the Hub, available to docker pull
• fsoppelsa/saltmaster has autobuild activated on the Hub

Enjoy 🍻
