 # Discourse
 
-[![Build Status](https://build.coopcloud.tech/api/badges/coop-cloud/discourse/status.svg?ref=refs/heads/main)](https://build.coopcloud.tech/coop-cloud/discourse)
+Wiki Cafe's configuration for a Discourse deployment. Originally slimmed down from an `abra` [recipe](https://git.coopcloud.tech/coop-cloud/discourse) by [Co-op Cloud](https://coopcloud.tech/).
 
-A platform for community discussion

+## Deploying the app with Docker Swarm
 
-## Basic usage
+Set the environment variables from the .env file during the shell session.
 
-1. Set up Docker Swarm and [`abra`]
-2. Deploy [`coop-cloud/traefik`]
-3. `abra app new discourse --secrets` (optionally with `--pass` if you'd like
-   to save secrets in `pass`)
-4. `abra app YOURAPPDOMAIN config` - be sure to change `$DOMAIN` to something that resolves to
-   your Docker swarm box
-5. `abra app YOURAPPDOMAIN deploy`
-6. Open the configured domain in your browser to finish set-up
+```
+set -a && source .env && set +a
+```
 
-[`abra`]: https://git.autonomic.zone/autonomic-cooperative/abra
-[`coop-cloud/traefik`]: https://git.autonomic.zone/coop-cloud/traefik
+Set the secrets.
 
-## To add a new Admin user
+```
+printf "SECRET_HERE" | docker secret create SECRET_NAME -
+```
 
-1. Login to the instance `abra app run APPNAME app sh`
-2. `cd /opt/bitnami/discourse`
-3. `RAILS_ENV=production bundle exec rake admin:create` and follow prompts.
+Deploy using the `-c` flag to specify one or multiple compose files.
 
-## Install plugins
-
-1. Login to instance `abra app run APPNAME app sh`
-2. `cd /bitnami/discourse/plugins/`
-3. `git clone plugingit` for example `https://github.com/discourse/discourse-openid-connect.git`
-4. `abra app restart APPNAME app`
-
-## Setup Notes
-
-Until issue #1 is fixed, the default user is `user` and the default password is `bitnami123`
+```
+docker stack deploy discourse --detach=true -c compose.yaml -c compose.smtpauth.yaml
+```
