Key Decisions + +- **Versioning strategy:** **CalVer** – releases are date‑based, no need for semantic breaking‑change signaling. +- **Docker tags:** `latest` (rolling) and `YYYY.MM.DD` (immutable). + - `latest` always points to the most recent build from `master`. + - Date tag allows pinning to a specific day's release. +- **Workflow triggers:** + - Run tests on every push/PR to catch issues early. + - Push Docker images **only from the `master` branch** – avoids polluting registry with feature‑branch images. +- **Test coverage:** Not measured in the main task (bonus adds coverage tracking). Current tests cover all endpoints and error cases. + +--- + +## 5. Challenges & Solutions + +| Challenge | Solution | +| ----------------------------------------- | ---------------------------------------------------------------------------------------------------------- | +| **Port 5000 already in use on macOS** | Used `PORT=8000` locally; tests use Flask test client, no port conflict in CI. | +| **Docker push skipped on feature branch** | Condition `if: github.ref == 'refs/heads/master'` – correct, merged `lab03` into `master` to trigger push. | +| **Snyk could not find dependencies** | Added `pip install` before `snyk test`. | +| **Snyk authentication error (401)** | Generated new Snyk API token, stored as `SNYK_TOKEN` secret, added explicit `snyk auth` step in workflow. | + +--- + +## 6. Conclusion + +βœ… **All main tasks completed successfully:** + +- Unit tests written and passing. +- GitHub Actions workflow with lint, test, security scan, and Docker build/push. +- Dependency caching and Snyk integration. +- Full documentation with evidence. + +The pipeline is now production‑ready and will be extended in future labs (monitoring, Kubernetes, GitOps). + +--- diff --git
