Note

: this recipe runs the official, experimental discourse/discourse image. Upstream does not yet recommend it for production — see https://meta.discourse.org/t/380646. Use with care.

Basic usage

1. Set up Docker Swarm and abra
2. Deploy coop-cloud/traefik
3. abra app new discourse --secrets
4. abra app config YOURAPPDOMAIN — set DOMAIN and DISCOURSE_DEVELOPER_EMAILS
5. abra app deploy YOURAPPDOMAIN
6. Open the configured domain in your browser to finish set-up. The first account that registers with an address listed in DISCOURSE_DEVELOPER_EMAILS becomes an admin.

The app serves plain HTTP on port 80; Traefik terminates TLS in front of it. The image's built-in nginx/Let's Encrypt is disabled by the recipe (install-ssl override) so it works behind the reverse proxy.

Add an admin user

abra app run YOURAPPDOMAIN app discourse admin create

Migrating from the previous (bitnami) recipe

The official image stores uploads under /shared rather than bitnami's /bitnami/discourse. On first boot the recipe copies uploads + backups from the old bitnami volume (mounted read-only at /legacy) into /shared, once, idempotently. The Postgres database is reused as-is. After a successful migration a later recipe version will drop the transitional /legacy mount.

If you are upgrading from the bitnami recipe, also remove the now-unused sidekiq service that swarm leaves behind (sidekiq runs inside the app container now):

docker service rm YOURSTACK_sidekiq
