Phase 4 of moving the API from Render to Cloud Run: a pipeline that tests, builds and pushes the API image on every backend merge to main. Deploys stay off until cutover.

backend/cloudbuild.yaml

  1. test: npm ci && npm test on node:24-bookworm-slim. The backend suite now runs somewhere other than a laptop, and a merge can't produce an image unless it passes.
  2. build / push: tags the image us-east4-docker.pkg.dev/<project>/devasign-api/api with :$SHORT_SHA and :latest.
  3. deploy: an image-only gcloud run deploy devasign-api, so env, secrets, scaling and the runtime service account stay as configured on the service. It is gated by _DEPLOY (default "false") and will be switched on at cutover. Deploying on every merge before then would start a second prod instance next to Render, and two bounty keepers on the same escrow.

It runs as a dedicated devasign-deployer service account, not the default compute account (which has project-wide run.admin). Its grants: Artifact Registry writer on the devasign-api repo only, run.developer, logging.logWriter, serviceAccountUser on devasign-api only, and object viewer on the _cloudbuild source bucket (for manual gcloud builds submit).

Node 22 → 24 (Dockerfile and CI)

On Node 22, 10 db-flush recovery tests are cancelled: they await a deliberately hung query with only unref'd timers pending, so the test process exits early ("Promise resolution is still pending but the event loop has already resolved"). The running server isn't affected, because its HTTP listener keeps the process alive, but every CI build would fail. Node 24 is the current LTS and passes everything.

Verification

  • Local, Node 24.11.1: 1820/1820 pass. The server boots with production-only deps, the prod guard refuses to boot without secrets, /api/health returns 200, and SIGTERM drains and exits 0.
  • Local, Node 22.13.1: 1810 pass, 10 cancelled (all in db-flush.test.ts). This is the failure above.
  • Cloud Build (build fb9d1d9f, as devasign-deployer): test 1820/1820 (418s), build, push (api:26996a8, latest), deploy skipped with "Deploy disabled (_DEPLOY=false)". SUCCESS.

After merge

The devasign-api-main trigger (push to ^main$, backend/**, ignoring backend/deploy/** and *.md) gets created once devasignhq/agent is connected in Cloud Build → Repositories (1st gen), which is a one-time console step.

Runs on pushes to main that touch backend/: the backend test suite,
then build and push the image to us-east4 Artifact Registry tagged with
the short SHA and latest. The deploy step is an image-only
`gcloud run deploy`, so env, secrets and scaling stay as configured on
the service; it is off (_DEPLOY=false) until the Render cutover, so
merges can't start a second prod instance beside Render.

On Node 22 the db-flush recovery tests are cancelled: they await a
deliberately hung query while only unref'd timers are pending, so the
test process exits early ("Promise resolution is still pending but the
event loop has already resolved"). The server itself is unaffected
(the HTTP listener keeps it alive), but CI would fail every build.
Node 24 (current LTS) passes all 1820 tests, and the server boots and
drains on SIGTERM with production-only deps.

Without dynamicSubstitutions, Cloud Build passed the literal
"${PROJECT_ID}" to docker build and the tag was rejected.

Tests by DevAsign

✅ Passed (5) · ⚠️ Unverifiable (1)

5 of 6 criteria verified by tests, 1 unverifiable. Each verdict below links to its evidence.

1 — The Cloud Build config runs a test step executing the backend test suite via `npm ci && npm test` on a Node 24 base image (`node:24-bookworm-slim`). (pass)

Verdict: pass

The cloudbuild test step runs npm ci && npm test on node:24-bookworm-slim in the backend directory, per all four subtest assertions.

Test: .devasign/tests/cloudbuild-test-step.test.mjs · integration

details

2 — The Cloud Build config builds and pushes the API image tagged `us-east4-docker.pkg.dev//devasign-api/api` with both the `:$SHORT_SHA` tag and the `:latest` tag. (pass)

Verdict: pass

The _IMAGE resolves to the expected Artifact Registry path, and build/push tag both :$SHORT_SHA and :latest.

Test: .devasign/tests/cloudbuild-build-push.test.mjs · integration

details

3 — The deploy step is an image-only `gcloud run deploy devasign-api` that is gated by a `_DEPLOY` substitution defaulting to `"false"`, so with the default the deploy is skipped. (pass)

Verdict: pass

_DEPLOY defaults to false, the deploy is an image-only gcloud run deploy devasign-api gated on _DEPLOY==true, and the simulated guard skips deploy by default.

Test: .devasign/tests/cloudbuild-deploy-gate.test.mjs · integration

details

4 — The image substitution expands `PROJECT_ID` (e.g. via dynamicSubstitutions) so the literal `${PROJECT_ID}` is not passed to docker build and the resulting tag is valid. (pass)

Verdict: pass

dynamicSubstitutions is enabled and both build and push steps reference ${_IMAGE} rather than a literal ${PROJECT_ID}.

Test: .devasign/tests/cloudbuild-image-substitution.test.mjs · integration

details

5 — The Dockerfile and CI configuration target Node 24 rather than Node 22. (pass)

Verdict: pass

Both backend/Dockerfile and cloudbuild.yaml target node:24-bookworm-slim with no reference to node:22.

Test: .devasign/tests/dockerfile-node24.test.mjs · integration

details

6 — The full backend test suite passes on Node 24 (all tests, including the db-flush recovery tests that were cancelled on Node 22). (unverifiable)

Verdict: unverifiable

The db-flush suite errored with pending Promise resolution and cancelled subtests, so it did not complete and cannot confirm the full suite passes on Node 24.

Test: backend/src/db-flush.test.ts (existing) · integration
