From 7dad9d97afbf1a4dd5d14ef73bb7bd3856468431 Mon Sep 17 00:00:00 2001 From: John Lightner Date: Tue, 7 Apr 2026 02:09:56 -0500 Subject: [PATCH] MAESTRO: Add entrypoint migrations, worker config, and stack integration tests Create docker/entrypoint.sh to run alembic migrations on API startup. Create backend/worker.py with Celery app config for the compose worker service. Fix README single-container port (8000) and add production compose documentation. Add 27 tests (stack integration + worker) verifying all Docker/compose artifacts are present, consistent, and the /health endpoint responds correctly. --- Auto Run Docs/01-scaffold.md | 3 +- README.md | 20 +++- backend/tests/test_stack_integration.py | 138 ++++++++++++++++++++++++ backend/tests/test_worker.py | 47 ++++++++ backend/worker.py | 30 ++++++ docker/Dockerfile | 8 +- docker/entrypoint.sh | 10 ++ 7 files changed, 250 insertions(+), 6 deletions(-) create mode 100644 backend/tests/test_stack_integration.py create mode 100644 backend/tests/test_worker.py create mode 100644 backend/worker.py create mode 100644 docker/entrypoint.sh diff --git a/Auto Run Docs/01-scaffold.md b/Auto Run Docs/01-scaffold.md index dabb6fd..7ebf253 100644 --- a/Auto Run Docs/01-scaffold.md +++ b/Auto Run Docs/01-scaffold.md @@ -44,4 +44,5 @@ Set up the PromptLooper repository, Docker infrastructure, and basic project ske - [x] Create frontend/src/api/client.ts with a typed API client using fetch.

The frontend should load and show the setup screen (since no admin exists). The database migration should have run. Document any manual steps needed in the README. + > Created missing backend/worker.py (Celery app config for docker-compose worker service). Created docker/entrypoint.sh that runs `alembic upgrade head` before starting uvicorn, and updated Dockerfile to use it as ENTRYPOINT. Fixed README single-container quick-start (port 8000, not 8400) and added production compose docs (service list, first-boot instructions). Added 24 stack integration tests verifying all Docker/compose/nginx/frontend/alembic files are present and consistent, plus /health endpoint test. 3 worker tests confirm Celery config.
