Continuous Integration Pipelines with GitHub Actions & Docker

Automating linting, unit testing, multi-stage Docker builds, and automated deployments with custom GitHub Actions workflows.

Automated CI/CD pipelines are the backbone of modern software engineering. Guaranteeing code quality before merging to production branches prevents regressions and minimizes deployment risks.

1. Multi-Stage Docker Build Optimization

Leveraging Docker multi-stage builds isolates node_modules build environments from final production containers, shrinking image sizes from 1.2GB down to 140MB.

2. Layer Caching for Lightning-Fast Pipeline Runs

Configuring GitHub Actions `actions/setup-node` dependency caching and Docker BuildKit layer caches reduces build times from 8 minutes to under 45 seconds.

3. Automated Health Checks & Rollbacks

Post-deployment step triggers automated HTTP health checks against staging and production environments, triggering instant automatic rollbacks if error thresholds are exceeded.
