To get Discourse up and running on Coolify, I followed this guide by Cristian Buleandra:

Running Discourse on Coolify

Discourse does not officially provide a Docker image to run their forum software, which makes it harder to install on Coolify. Solution: Use the Bitnami Discourse Docker Image with a custom docker-compose file. ⚠️Make sure to replace the following placeholders👇 PASSWORD_YOUR_DISCOURSE_PASS (al…

The article provdes a Docker Compose .yml file that works for Coolify (with a few tweaks – check the comments).

It essentially installs the Bitnami Docker Image.

Access the Docker Container (Web UI)

Once Discourse is up and running, you can install plugins via Coolify by accessing the terminal for your Discourse container.

Go to Terminal>discourse container.

Plugin Installation Steps

Once your container is logged into, the steps below will install a plugin (which I found on the Bitnami website):

1. Open the discourse install directory:

cd /opt/bitnami/discourse

2. install the plugin from the GItHub Url:

RAILS_ENV=production bundle exec rake plugin:install repo=PLUGIN_REPO_URL

3. Precompile new plugin assets:

RAILS_ENV=production bundle exec rake assets:precompile

4. Finally, run the database migrations - this is needed for plugins that require database changes, such as Discourse Reactions plugin.

RAILS_ENV=production bundle exec rake db:migrate

That's it, to uninstall a plugin, follow the guide here.
