Replaces the previous hand-rolled MigrateWithLock + GORM AutoMigrate path,
which had two compounding problems:
- AutoMigrate ran on every pod startup (~5 min over the transatlantic
link) even when no schema changes had landed
- pg_advisory_lock is session-scoped, which silently fails through
Neon's pgbouncer transaction-mode pooler — turns out this is a
known and documented limitation that bites golang-migrate too
Goose was chosen over golang-migrate (the other heavyweight) because:
- Goose wraps each migration file in a transaction by default, so a
failure rolls back cleanly instead of leaving a "dirty" version
state requiring manual force-reset (golang-migrate's known
weakness, per its own issue tracker — see #1001 + Atlas's writeup)
- Goose's locking is opt-in. We don't opt in: migrations run as a
single Kubernetes Job, which IS the singleton process. No advisory
lock needed at all.
Layout:
- migrations/000001_init.sql — schema-only pg_dump of the live Neon
DB at adoption, stripped of psql-only directives that block goose's
bookkeeping insert. Pre-goose hand-numbered migrations 002-022 had
their effects folded into this baseline; deleted from the live tree
but preserved in git history at 58e6997.
- Dockerfile installs `goose v3.22.1` at build time and copies the
binary into the api image. The migrate Job reuses the api image with
command=goose, so no separate image to build/push/version.
- deploy-k3s/manifests/migrate/job.yaml: a one-shot Job that strips
the -pooler segment from DB_HOST (advisory lock won't survive
pgbouncer transaction-mode), runs `goose up`, exits.
- deploy-k3s/scripts/03-deploy.sh: deletes any prior Job, applies the
fresh one, `kubectl wait --for=condition=complete --timeout=10m`,
then proceeds with api/worker rollout. Job failure aborts the deploy
before any new app pod sees a stale schema.
- internal/database/database.go::RequireSchemaApplied checks
goose_db_version on startup. api/worker refuse to boot if the
table is missing or its latest row has is_applied=false — the
fail-fast for "operator forgot to run migrate."
- Makefile: migrate-up / migrate-down / migrate-status / migrate-new
for local workflow.
Production DB was bootstrapped manually:
$ goose -dir migrations postgres "$DSN" version # creates table
$ psql ... -c "INSERT INTO goose_db_version (version_id, is_applied, tstamp) VALUES (1, true, NOW());"
Smoke test against fresh Postgres locally: 50 user tables created in
284ms via `goose up`, version_id=1 + is_applied=t recorded.
Verified the local goose CLI talks to prod successfully:
$ goose ... status
Applied At Migration
