Redis becomes mandatory infrastructure (PostgreSQL-parity): the
REDIS_ENABLED flag, NullCache backend, and every conditional caching
code path are removed. /health/ready reports not_ready (503) when
Redis is unreachable and cached endpoints return 503 instead of
silently degrading; invalidation helpers never raise after a
committed write.
The bundled redis container joins the core profile only via
docker-compose.dev.yml (production points REDIS_* at an external
instance, same no-shadowing pattern as postgres), the backend suite
runs against real Redis (test-redis on 127.0.0.1:55433, CI redis:8
service container, per-xdist-worker key prefixes), and operator docs
describe the required-dependency setup (upgrading.md gains the
v0.20.0 section).
Starting core with docker-compose.prod.yml also started the bundled
postgres container, whose 'postgres' network alias shadowed a shared
instance of the same name on the same Docker network — the live site
silently talked to an empty local database instead of DATABASE_HOST.
- Base file: postgres profiles are now [all, postgres] (core dropped);
the dev override unions 'core' back in, so the documented dev
workflow (make up, --profile core) is unchanged
- migrate's postgres dependency is required: false — still health-gated
when the bundled container is active, skipped when profile-inactive
- prod override documents the behavior; opt in explicitly with
--profile postgres (or --profile all) for a bundled production DB
- Docs: database.md/deployment.md/configuration.md/README/.env.example
updated; upgrading.md gains a one-time cleanup runbook (full down to
remove the previously started hub-postgres container)
- Remove monitoring services from all docker compose files — monitoring is now
user-managed infrastructure (users point their own Prometheus at /metrics)
- Remove metrics profile, prometheus/alertmanager volumes from Makefile
- Update README Getting Started: packet capture is included via --profile receiver,
not a separate prerequisite; add remote observers guide
- Add --profile all to all docker compose command examples in README and UPGRADING.md
- Simplify UPGRADING.md backup/migration to only meshcore_hub_data
