Add `rig db dump <container> [outfile]` and
`rig db restore <artifact> <container> [db] [--yes]` — imperative on-box
PostgreSQL tooling, the interactive counterpart to the scheduled,
declarative `coolify backup install`.
Key decisions:
- Dumps carry `--clean --if-exists --no-owner --no-acl`. `--no-owner
--no-acl` is mandatory for cross-instance restores: the target's
superuser differs (Coolify randomizes it), so a plain dump aborts under
ON_ERROR_STOP=1 on the first GRANT/ALTER OWNER for a missing role.
- $POSTGRES_USER/$POSTGRES_DB are read INSIDE the container (single-quoted
`sh -c`), never hardcoded to `postgres` on the host.
- restore connects as the container's own superuser and runs with
ON_ERROR_STOP=1; the optional [db] arg targets a NAMED database in a
shared container, passed in via a container env var rather than string
splicing.
- restore overwrites the target, so it prompts y/N; --yes/--force is the
automation bypass. Artifact existence/non-emptiness is checked before
the confirm gate and before anything touches the DB.
- dump uses pipefail + a sibling temp promoted only on success, and
refuses to keep an empty artifact — a failed pg_dump must never leave a
plausible-looking .gz behind.
Args are validated before the root check (testable without root); guards
are root, Debian-family warn, docker, and gzip/gunzip. Adds CLI tests and
a `### rig db` README section.

runner install is convergent by skipping: it sees a registered runner and
leaves it alone. So rig could create a runner and never move or destroy one,
and re-pointing a box at a different repo meant hand-rolled config.sh/svc.sh
incantations against an install layout only rig knew about.
- status: repo, name, labels, dir, unit — read-only, no token, no network.
- remove: service down, then deregister. --local wipes the box without
contacting GitHub, leaving a stale entry to delete by hand.
- repoint: remove + re-register in one act, keeping the runner's name and
reusing the binary already on the box.
The service always comes down before deregistration in both paths: GitHub's
removal throws "Uninstall service first" while the service is configured, and
--local bypasses that check entirely, which would strand a running service
pointed at deleted config.
repoint collects both tokens up front — a token you turn out not to have must
fail while the runner is still registered, not halfway through the move.
Labels are the sharp edge: GitHub holds them, the runner does not persist
them, and they are what runs-on matches. install now records what it
registered with so repoint and status can read it back; a runner installed
before that has nothing to read, so repoint falls back to the ci-runner
default and warns before it touches anything.
The Coolify control-plane database holds the GitHub App private key, every
registered server's SSH key, and every environment value for every environment
it manages. Backing it up was a manual runbook step, and the dump script lived
in cast — the off-box tool, whose src never references it. It runs on the box,
as root, under a scheduler: that is rig's job description.
It matters beyond tidiness. The dump is forensics, not a restore path — a lost
control plane is rebuilt fresh and reconciled from the manifest. So there will
be a next control-plane box, and as a runbook step it was born un-backed-up,
depending on someone remembering mid-incident. Now it is backed up from birth.
rig installs the machinery and templates /etc/coolify-dump.env empty at 0600,
never reading it back — no credential passes through rig. The script's own
guards make an unfilled file fail the unit loudly rather than ship plaintext.
systemd timer over cron: EnvironmentFile is the right idiom for 0600 secrets,
failures surface in systemctl status instead of being mailed into the void, and
Persistent=true catches a run missed while the box was down.
Two hazards the cast script missed, carried into the unit:
- aws-cli >= 2.23 enables default upload checksums that S3-compatible backends
reject; Debian 13 ships 2.23.6, so the unit defaults both checksum knobs to
when_required.
- A failed pg_dump piped into age still yields a valid, tiny, encrypted file
that uploads cleanly every night and looks exactly like a working backup. The
script now refuses to upload an empty artifact.
