# 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 config YOURAPPDOMAIN` - be sure to change `$DOMAIN` to something that resolves to
your Docker swarm box
5. `abra app deploy YOURAPPDOMAIN`
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 plugin.git` for example `https://github.com/discourse/discourse-openid-connect.git`
4. `abra app restart YOURAPPDOMAIN app`
### Events / calendar plugin
We've had some luck running [discourse-events](https://github.com/paviliondev/discourse-events).
## Setup Notes
Until issue #1 is fixed, the default user is `user` and the default password is `bitnami123`
## Postgres major version upgrades
Welcome to hell.
1. `abra app run YOURAPPDOMAIN db pg_dumpall -U discourse | gzip > YOURAPPDOMAIN_db_DATE.sql.gz`
2. `abra app volume ls YOURAPPDOMAIN`, find the name of the Postgres data volume
3. `scp` the backup to your VPS
4. `abra app undeploy YOURAPPDOMAIN`
5. `abra app volume rm YOURAPPDOMAIN`, choose the Postgres data volume
6. `abra app deploy YOURAPPDOMAIN`, then `abra app undeploy YOURAPPDOMAIN`
7. `ssh` to the VPS, run (replacing `13-alpine` with the new Postgres version)
`docker run -v YOURDATAVOLUME:/var/lib/postgresql/data -e POSTGRES_HOST_AUTH_METHOD=trust -it postgres:13-alpine`
8. In another SSH session on the server, run `docker ps` to find the ID of the
new Postgres container, then `docker exec -it CONTAINERID bash`
9. In the shell you just launched, run `dropdb -U discourse discourse`, then
`createdb -U discourse discourse`, then Ctrl+D or run `exit`
10. In the second SSH session, run `zcat YOURAPPDOMAIN_db_DATE.sql.gz | docker exec -it CONTAINERID psql -U discourse`
11. Exit the second SSH session
12. Back in the first SSH session, Ctrl+C to shut down the database
13. `abra app deploy YOURAPPDOMAIN`
```
docker stack deploy discourse -c compose.yaml -c compose.smtpauth.yaml
```
