build: optimize API container image

[mw-slc]

Summary

• add a dedicated multi-stage API Dockerfile
• prune the monorepo to the API dependency graph before installing
• keep native build tools out of the runtime image
• preserve Prisma migrations and generated client required at startup
• exclude local build artifacts and secrets from Docker context

Motivation

The generated OpenShip image copied the complete workspace into a 2.61 GB runtime layer. A single API deployment took roughly 21 minutes, mostly copying and exporting dependency layers.

Validation

• Dockerfile policy test passes
• clean staging Docker build in progress
• runtime health and migration verification will be added after the image completes

---

Summary by cubic

Optimizes the API container by replacing the generated OpenShip image with a dedicated multi-stage Dockerfile.api that prunes the monorepo to the API dependency graph. The old image copied the entire workspace (≈2.61 GB) and took ~21 minutes to deploy; the new image is smaller, builds faster, and keeps build tools out of runtime.

• Adds .dockerignore to exclude local artifacts and secrets from the Docker context.
• Introduces Dockerfile.api:
  • Prunes with turbo prune api --docker, installs only API graph deps with bun, and builds the API; native tools (python3, make, g++) exist only in the builder.
  • Preserves Prisma artifacts: runs client generate at build and runs packages/db db:deploy on container start.
  • Runtime uses oven/bun:slim, copies only pruned deps, apps/api/dist, and packages (including packages/db), and serves on port 3001.
• Adds scripts/test-api-dockerfile.sh to enforce pruning, native build tooling in builder only, presence of migrations, and no full-workspace copy.

Required actions:

• Update CI/CD to build with -f Dockerfile.api from the repo root.
• Set DATABASE_URL at runtime; the container now applies migrations on start. If you run migrations elsewhere, override the container CMD/entrypoint to omit db:deploy.

Someone is attempting to deploy a commit to the Comp AI - PoC Team on Vercel.

A member of the Team first needs to authorize it.

[github-actions]

Retargeted this onto main.

release is the default branch so that a plain clone runs the last tagged release, but nothing merges into it — it is fast-forwarded onto the tag by the Release workflow and that is all. Changes go to main, and reach release when a release is cut.

Nothing is wrong with your branch. If the diff now shows commits that are already on main, rebase and force-push:

git fetch origin main
git rebase origin/main
git push --force-with-lease

Copy lifecycle inputs before installing dependencies

During every clean image build, Bun runs workspace postinstall scripts against only out/json. The API script and Prisma schema arrive after this step. Installation stops before the build stage completes.
