Multiple app containers for a single Discourse site

You can host multiple standalone Discourse installs on a single server (separate containers / separate ports / separate app.yml), without using Discourse “multisite”.

I do something similar, with a single web-only-style container per site and traefik (though I"ve also got a setup using nginx-proxy) as reverse proxy. I tried HAproxy for a while (it’s what CDCK uses, last I knew), but found it cumbersome.

• external Redis (single instance)

I am pretty sure that you need one redis per Discourse server.

Each Discourse needs its own totally separate redis server because message-bus uses Redis Pub/Sub, which is shared between all databases on a Redis server.
