Fun with Discourse on Docker

Discourse is a popular forum tool available as a self-hosted open-source tool. It can be installed bare-metal on Linux, but the Docker installation is one that I found most interesting. Unlike most Docker-implemented tools, Discourse has a script that runs outside of the docker containers (on your base machine) to set up the tool. This monolithic script (./discourse-setup) seems to do many of the things that docker-compose does, but obviously worse. I’m no fan of doing things this way; especially when the base alternative is nowhere on their site. My challenge this time was to build a basic docker-compose.yml that would get Discourse running in a test environment. Here’s what I did.
