Makes schema changes deploy automatically: edit schema -> db:generate ->
commit -> push -> Dokploy redeploys -> migrations apply on container start.
No more Dokploy database terminal.
Components:
- src/db/migrate.ts: standalone migrator (single short-lived connection,
fails loud on error so a bad migration crashes the container instead of
letting the app serve a half-migrated schema)
- scripts/build-migrator.mjs: esbuild bundles migrate.ts -> dist/migrate.mjs
with drizzle-orm + postgres inlined. Needed because Next.js standalone
output keeps neither as a separate node_modules package.
- Dockerfile: builder runs db:build-migrator; runner copies migrate.mjs +
drizzle/; CMD is 'node migrate.mjs && node server.js'
- package.json: db:generate / db:migrate / db:studio / db:pull /
db:build-migrator scripts; esbuild promoted to an explicit devDependency
- pnpm-lock.yaml resynced
BUG FIX: .dockerignore had 'drizzle/' — migration SQL was excluded from the
build context, so even a correct Dockerfile COPY would have found nothing.
This was the second half (with the .gitignore bug in commit 1) of why the
migration pipeline never worked. Now only _archived/_introspected are
excluded.
Verified: full docker build succeeds; runner image contains migrate.mjs +
drizzle baseline; migrator tested end-to-end against a scratch DB (35
tables created, __drizzle_migrations populated, idempotent on rerun).
