Moving away from manual deployments and building an automated CI/CD pipeline is the core of modern DevOps. Here we implement full automation — testing, building, and deploying — using Docker Compose and GitHub Actions.
Pipeline Architecture
The full flow: PR creation → automated tests → code review → merge → Docker image build → registry push → server deployment.
Multi-Stage Docker Build
Using cargo-chef for dependency caching in the Rust API reduces build times by 70%.
GitHub Actions Workflow
Matrix builds allow parallel processing of frontend, backend, and infrastructure changes — minimizing total pipeline execution time.
Health Checks and Rollback Strategy
Perform automatic health checks after deployment and implement safe rollback to the previous version on failure.
