From 7157877f0ba5bb778411b5aa1efd298185a40282 Mon Sep 17 00:00:00 2001 From: xcaliber Date: Wed, 4 Feb 2026 18:17:07 +0000 Subject: [PATCH] feat: Setup CI/CD infrastructure with Go, Frontend, and Docker workflows (#22) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit ## Summary This PR sets up the complete CI/CD infrastructure for the Chat Switchboard project, implementing automated testing, linting, building, and Docker containerization. ## Changes ### CI/CD Workflows 1. **`.gitea/workflows/backend.yml`** - Backend CI pipeline - Automated Go module initialization - Test execution with coverage reporting - Code linting with golangci-lint - Binary compilation with version tags - Artifact upload for debugging 2. **`.gitea/workflows/frontend.yml`** - Frontend CI pipeline - JavaScript linting with ESLint - CSS validation with Prettier - Standalone HTML build via build.sh - HTML structure validation - Build artifact management 3. **`.gitea/workflows/docker.yml`** - Docker CI pipeline - Backend container building and testing - Frontend container building - Automatic image tagging on tags/branches - Registry push on main branch - Multi-arch manifest creation ### Docker Configuration - `server/Dockerfile` - Multi-stage Go backend container with health checks - `Dockerfile.frontend` - Nginx frontend container with gzip compression - `nginx.conf` - Optimized nginx config with security headers ### Dependencies - `server/go.mod` - Initialized Go module with Gin and godotenv ### Documentation - `docs/CICD_SETUP.md` - Comprehensive CI/CD documentation ## Features - ✅ Auto-trigger on push/PR to main/develop - ✅ Test coverage reporting - ✅ Code quality checks (golangci-lint, ESLint) - ✅ Build artifact management (7-day retention) - ✅ Semantic versioning support (v* tags) - ✅ Multi-stage Docker builds - ✅ Container health checks - ✅ Security headers in nginx - ✅ Gzip compression - ✅ Non-root container execution ## Testing The workflows will automatically run on this PR. Once merged, all future PRs and pushes to main/develop will trigger the appropriate CI checks. ## Acceptance Criteria - ✅ All PRs run CI checks - ✅ Docker images auto-build on tags - ✅ Standalone build generates on each commit ## Next Steps (Manual) 1. Merge this PR to `main` 2. Create `develop` branch: `git checkout main && git checkout -b develop && git push origin develop` 3. Configure branch protection in Gitea (Settings → Branches → Add protection rule for main/develop) 4. Test with a sample PR to verify CI runs ## Breaking Changes None. This is purely infrastructure setup with no impact on existing functionality.
