A production-style CI/CD pipeline built with Azure DevOps, automating the full lifecycle of a containerised FastAPI application — from automated testing to deployment on Azure Container Apps.
Every git push to main triggers a 3-stage pipeline: Test → Build → Deploy
| Stage | What happens |
|---|---|
| Test | pytest runs automatically — build blocked if tests fail |
| Build | Docker image built for linux/amd64 and pushed to ACR |
| Deploy | Azure Container Apps updated with new image revision |
Developer → git push → Azure DevOps Pipeline
Stage 1: pytest
Stage 2: docker buildx → ACR
Stage 3: az containerapp update

Azure Container Apps
| Layer | Tool |
|---|---|
| App | Python / FastAPI |
| Containerisation | Docker (buildx — linux/amd64) |
| Container Registry | Azure Container Registry (ACR) |
| CI/CD | Azure DevOps YAML Pipelines |
| Hosting | Azure Container Apps |
| Testing | pytest |
- 3-stage YAML pipeline: Test → Build → Deploy
- Automated pytest on every push — pipeline fails fast if tests break
- Multi-platform Docker build via docker buildx
- Zero-downtime deployment via Azure Container Apps revisions
- ACR image tagged with Azure DevOps Build ID for full traceability
Pipeline successfully deployed to Azure Container Apps (Southeast Asia region). Infrastructure has been torn down to avoid ongoing costs.
