## Standing notes
|
|
- bitnami/discourse was removed from Docker Hub; bitnamilegacy/discourse is the byte-identical archived
|
|
drop-in. The recipe (PR #1) re-pins to bitnamilegacy/discourse. The cc-ci overlay (compose.ccci.yml)
|
|
also re-pins the base deploy.
|
|
- bitnamilegacy/discourse is FROZEN at `3.5.0` (last runnable tag, pushed 2025-08-22; no 3.5.x patch tags
|
|
exist). The `9.0.4`/`9.0.3` tags abra reports as upgrades are **Helm chart OCI artifacts**
|
|
(`media_type: application/vnd.cncf.helm.config.v1+json`, ~186 KB, `tag_status: inactive`, 0 images) —
|
|
NOT runnable container images. Do NOT bump app/sidekiq to 9.x. The real Discourse app image upgrade is
|
|
the official `discourse/discourse` image, tracked in PR #5 (discourse-official-image) / PR #7
|
|
(discourse-official, +db → discourse/postgres:pg18). Confirmed directly via Docker Hub API 2026-06-22.
|
|
- postgres major version upgrades require operator action: pg_dumpall backup → undeploy → delete data
|
|
volume → redeploy → restore. See recipe README "Welcome to hell" section. Do NOT auto-bump postgres
|
|
more than one major at a time.
|
|
- PR #2 (upgrade-0.8.0+3.5.0) upgrades discourse 3.3.1→3.5.0 and postgres:13→pgvector/pgvector:pg17.
|
|
That is a 4-major postgres jump; operators MUST follow the manual dump/restore procedure in the README.
|
|
- Redis 8.0 GA supports upgrade from 7.x data files. Discourse uses Redis only as a cache/queue (no
|
|
persistence modules). Redis 8.0 integrates RediSearch/RedisJSON/etc. as built-ins; discourse does not
|
|
use those modules so this is transparent.
|
|
- bitnami/discourse:3.3.1 bundles pg_dump v13 internally; if using external postgres >13, backup hooks
|
|
that call pg_dump from within the app container may emit version-mismatch warnings (non-fatal for
|
|
simple schemas, but worth noting). The cc-ci ops.py backup test uses psql from the db container,
|
|
bypassing this.
