Replace the bitnami-era pgvector:pg17 db + hand-rolled pg_upgrade entrypoint with discourse/postgres:pg18 (pgvector + discourse's auto-upgrade layer, as suggested on coop-cloud/discourse#16). The image runs the in-place major-version pg_upgrade itself on boot, so the recipe just configures it via env: - the db password secret is read into $DB_PASSWORD by a small inline entrypoint (the image expects it in the env, no *_FILE support; the base image's POSTGRES_PASSWORD_FILE can't be used because run-postgres.sh pre-generates POSTGRES_PASSWORD). No separate entrypoint file/config any more. - POSTGRES_USER (the install user pg_upgrade must match) defaults to the image's 'postgres' -- correct for fresh installs and bitnami-origin clusters -- and is overridable from the app .env for a cluster bootstrapped with another superuser. - POSTGRES_INITDB_ARGS=--no-data-checksums so the new pg18 cluster matches the pre-18 clusters (pg18 initdb enables checksums by default; pg_upgrade needs a match). - mount postgresql_data at /var/lib/postgresql (versioned PGDATA .../18/docker) - pg_backup.sh: detect the superuser at runtime; fix paths for the new layout - document POSTGRES_USER override in .env.sample and README - bump PG_BACKUP_VERSION v3; drop DB_ENTRYPOINT_VERSION + entrypoint.postgres.sh.tmpl Verified on cctest: pg17->pg18 upgrade (install user 'postgres', checksums off) preserves data and serves over HTTPS; fresh install also works.

Note
: this recipe runs the official, experimental
discourse/discourseimage. Upstream does not yet recommend it for production — see https://meta.discourse.org/t/380646. Use with care.
Basic usage
- Set up Docker Swarm and
abra - Deploy
coop-cloud/traefik abra app new discourse --secretsabra app config YOURAPPDOMAIN— setDOMAINandDISCOURSE_DEVELOPER_EMAILSabra app deploy YOURAPPDOMAIN- Open the configured domain in your browser to finish set-up. The first account
that registers with an address listed in
DISCOURSE_DEVELOPER_EMAILSbecomes 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
Postgres major version upgrades
Handled automatically by the discourse/postgres image (pgvector + an
auto-upgrade layer). On deploy it finds an older cluster, installs the old
binaries and runs pg_upgrade into the new versioned data directory. No manual
dump/restore needed.
pg_upgrade must run as the old cluster's bootstrap superuser (its "install
user"). The recipe uses POSTGRES_USER, which defaults to postgres — the right
value for fresh installs and for clusters that came from the old bitnami recipe.
If your cluster was bootstrapped with a different superuser (e.g. discourse),
set POSTGRES_USER in the app .env before upgrading, otherwise pg_upgrade
will refuse with an install-user mismatch.
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
