Deploy to VPS / deploy (push) Has been cancelled
The previous container restart loop ("Error: Cannot find module 'effect'")
happened because the runner stage cherry-picked only specific Prisma
subdirs (.prisma, @prisma, prisma) but missed transitive runtime deps
of the Prisma CLI — like @prisma/config's dep on `effect`.
Cherry-picking is fragile: any minor Prisma upgrade changes the
required dep set and the container stops booting.
Real fix: introduce a dedicated prod-deps stage that runs
`npm ci --omit=dev --include=optional` and ship the resulting
node_modules wholesale to the runner. Trade-off: the runner image
grows by ~200-300MB, gaining bullet-proof prod CLI execution in
exchange. Subsequent rebuilds are fully cached after the first run.
What changed in Dockerfile:
- New stage `prod-deps` produces a prod-only node_modules tree
- Runner stage drops the explicit @prisma/prisma/sharp/@img copies
(they're already in prod-deps' node_modules)
- Still copies prisma/, prisma.config.ts, .prisma generated client,
and Next.js standalone artefacts
- CMD unchanged: migrate deploy + server.js
