discourse Salt States

Install using salt-ssh '<server-name>' state.sls discourse (replace <server-name> with the instance name from salt roster file).

The salt state does the following:

• install docker
• install postfix for sending mails (relay via cebe.cc mail cluster)
• install discourse
• install nginx as a reverse-proxy in front of discourse

You can access discourse on the server host name, e.g. https://discourse.example.com
