## Basic usage
|
|
|
|
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
|
|
|
|
[`abra`]: https://git.autonomic.zone/autonomic-cooperative/abra
|
|
[`coop-cloud/traefik`]: https://git.autonomic.zone/coop-cloud/traefik
|
|
|
|
## To add a new admin user
|
|
|
|
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.
|
|
|
|
## 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`
