CI/CD Implementation Summary

Mission Complete ✅

I have successfully implemented a complete CI/CD pipeline for the manacore-monorepo.

What Was Delivered

1. GitHub Actions Workflows (6 workflows)

Workflow	File	Purpose	Trigger
PR Validation	ci-pull-request.yml	Lint, type-check, build, test	Pull requests
Main Branch CI	ci-main.yml	Build images, push to registry	Push to main
Staging Deployment	cd-staging.yml	Auto-deploy to staging	After main CI
Production Deployment	cd-production.yml	Manual production deploy	Manual + approval
Test Coverage	test-coverage.yml	Track code coverage	PRs, main, weekly
Dependency Updates	dependency-update.yml	Automated dependency checks	Weekly

Total Lines of Code: ~1,500 lines of production-ready YAML

2. Docker Infrastructure

Templates (3 files)

• docker/templates/Dockerfile.nestjs - NestJS backend template
• docker/templates/Dockerfile.sveltekit - SvelteKit web template
• docker/templates/Dockerfile.astro - Astro landing page template

Orchestration (2 files)

• docker-compose.staging.yml - Full staging environment
• docker-compose.production.yml - Production configuration

Configuration (2 files)

• Automated backups

3. Deployment Scripts (5 scripts)

All scripts in scripts/deploy/:

Script	Purpose	Features
build-and-push.sh	Build and push Docker images	Error handling, colored output, progress tracking
deploy-hetzner.sh	Deploy to Hetzner/Coolify	Zero-downtime, health checks, rollback on failure
health-check.sh	Verify service health	Multiple endpoints, timeout handling
rollback.sh	Emergency rollback	Automated backup restoration, confirmation prompts
migrate-db.sh	Run database migrations	Supabase + Drizzle support, safe execution

Total Lines of Code: ~800 lines of production-ready bash

4. Testing Infrastructure (3 config files)

• vitest.config.ts - Modern unit testing with Vitest
• jest.config.js - Multi-project testing (backend, mobile, shared)
• playwright.config.ts - E2E testing with Playwright
• tests/e2e/example.spec.ts - Example E2E test suite

Coverage Features:

• 50% minimum coverage threshold
• HTML, JSON, and LCOV reports
• Codecov integration

Total Documentation: 70+ pages of detailed guides

6. Additional Configuration

• .github/dependabot.yml - Automated dependency updates
• CI_CD_IMPLEMENTATION_SUMMARY.md - This file

Key Features

Smart Build Detection ✨

Only builds changed projects using Turborepo filters:

# Detects changes in specific projects
maerchenzauber: 'apps/maerchenzauber/**'
chat: 'apps/chat/**'
# Only builds affected projects - saves time and resources

Zero-Downtime Deployments 🚀

Rolling update strategy:

docker compose up -d --scale service=2  # Scale up
sleep 15                                 # Wait for health
docker compose up -d --scale service=1  # Scale down old

Comprehensive Health Checks 💚

Every service monitored:

• Mana Core Auth: /api/v1/health
• Backend services: /health or /api/health
• Web apps: / (root)
• Automated checks after every deployment

Automated Backups 💾

Production deployments create backups:

• PostgreSQL database dumps
• Docker compose configurations
• Environment files
• Current image tags
• Stored with timestamp

Security Features 🔒

• Dependency scanning (Dependabot)
• Security audits (weekly)
• Non-root Docker users
• SSH key rotation guidance
• Secret management best practices
