forgejo_db has been at 0/1 replicas since 2026-07-29 01:24 UTC. Postgres hit
an invalid data-directory lock file ("could not open file postmaster.pid ...
performing immediate shutdown because data directory lock file is invalid")
and exited 0. With restart_policy.condition=on-failure, Swarm read the zero
status as successful completion, marked the task Complete, and never
rescheduled it.
The forgejo service itself stayed Up and kept serving its homepage, so the
outage presented as every repository page, the whole API and all CI returning
500 with "dial tcp: lookup db on 127.0.0.11:53: no such host" — including the
auth path, which is why API calls reported "user does not exist [uid: 0]"
rather than a database error.
on-failure cannot distinguish "finished successfully" from "shut itself down
and should be restarted", and Postgres exits 0 on several such paths, so it is
the wrong policy for an always-on stateful service.
This is the durable fix; it does not restart the currently stopped task.
Phase 1 of moving the secret store to OpenBao. Nothing is cut over:
TG_SECRETS_BACKEND defaults to sops for all three environments, so SOPS
remains authoritative until an environment is flipped in a reviewed PR.
The reason for the migration is one specific failure class. infra/CLAUDE.md
requires that vps1 never hold prod credentials, but that rule is currently
enforced by a caller-side shell flag (THERMOGRAPH_SECRETS_SKIP_COMMON) at
three call sites. A fourth call site, or one by-hand render, writes both S3
keypairs, the VAPID private key, REGISTRY_TOKEN and the IndexNow/metrics
tokens onto the Forgejo CI-runner box and exits 0. policies/tg-host-dev.hcl
makes that a 403 instead: dev's identity cannot read the common path at all.
Shape:
- vps2 only, native systemd (not a container: a Swarm service is circular,
and a plain docker run is one `prune -a` from gone), raft storage (2.6.0
deprecated the file backend), static auto-unseal so a reboot cannot block
deploys, mesh-only self-signed TLS (not ACME — that would put DNS in the
boot chain of the secret store).
- AppRole per environment, CIDR-bound, 5-minute tokens. Each environment's
secret-id is owned by its own deploy user, which is a boundary that does
not exist today since prod and beta both reach the same root-owned age key.
- Render still produces the same raw unquoted dotenv: Centralis compares
/etc/thermograph.env textually and the Swarm entrypoint parses it by line.
The backend dispatch in render-secrets.sh returns early rather than
refactoring the shared write path, so the SOPS path stays byte-identical.
Verified by rendering dev (12 keys) and prod (32 keys) through it, matching
the live hosts. The duplicated write path is noted for consolidation once
prod has been on OpenBao for a release cycle.
The OpenBao renderer rejects values containing a newline or a shell
metacharacter. /etc/thermograph.env is sourced by bash in six places, so
such a value is a command-execution path on the deploy host; the SOPS path
has always had this hazard and avoids it only because every current value
happens to be alphanumeric.
Also records that the age keypair is NOT retired by this migration: it is
the backup encryption key for every off-box dump (ops-cron.yml:142,197,
30-day retention), so deleting it with the vault files would silently
destroy a month of database recoverability.
verify-parity.sh is the cutover gate — it renders both backends and diffs
them, reporting key names and counts only, never values.
