🚀 JobApp CI/CD Pipeline

📋 Quick Overview

This repository implements a comprehensive CI/CD pipeline with:

• 4 Testing Layers (Unit, Integration, E2E, Security)
• 7 CI Phases (Lint → Unit → Integration → E2E → Docker → Security → Summary)
• 3 CD Phases (Build → Deploy → Summary)
• Branch-based Workflow (feature/fix → staging → main)

🌳 Branch Strategy

gitGraph
    commit id: "Initial"
    branch staging
    checkout staging
    commit id: "Staging Ready"
    branch feature/auth
    checkout feature/auth
    commit id: "Add Auth"
    checkout staging
    merge feature/auth
    branch fix/login-bug
    checkout fix/login-bug
    commit id: "Fix Login"
    checkout staging
    merge fix/login-bug
    checkout main
    merge staging id: "Production Deploy"

Loading

Workflow Rules:

• feature/* → staging: Manual merge (no CI)
• fix/* → staging: Manual merge (no CI)
• staging → main: PR triggers CI pipeline
• main: Push triggers CD pipeline

🔄 Pipeline Architecture

CI Pipeline (Pull Request: staging → main)

Phase 1: Lint & Validate
    ↓
Phase 2: Unit Tests ←→ Phase 3: Integration Tests (parallel)
    ↓
Phase 4: E2E Tests
    ↓
Phase 5: Docker Build & Test
    ↓
Phase 6: Security Scan (SBOM + Trivy + Cosign)
    ↓
Phase 7: CI Summary

CD Pipeline (Push to main)

Phase 1: Build & Push Production Images
    ↓
Phase 2: Deploy to Render
    ↓
Phase 3: Deployment Summary

🧪 Testing Layers

Layer	Type	Tools	Purpose	Duration
1️⃣	Unit Tests	PHPUnit, Jest	Individual components	~5 min
2️⃣	Integration Tests	PHPUnit, API Tests	Component interactions	~10 min
3️⃣	E2E Tests	Playwright	Complete user flows	~20 min
4️⃣	Security Tests	Trivy, Syft, Cosign	Vulnerabilities & compliance	~5 min

🚀 Quick Start

1. Initial Setup

# Run the setup script
./.github/setup-repository.sh

# Or manually install dependencies
cd backend && composer install
cd frontend/web && npm install

2. Configure Secrets

In GitHub repository settings, add:

RENDER_API_KEY=your_render_api_key
RENDER_SERVICE_ID=your_render_service_id

3. Set Branch Protection

Apply rules from .github/branch-protection.yml:

• Require PR reviews (2 approvers for main)
• Require status checks to pass
• Restrict force pushes

4. Test the Pipeline

# Create a feature branch
git checkout -b feature/test-ci

# Make changes and push
git add .
git commit -m "Test CI pipeline"
git push origin feature/test-ci

# Merge to staging (no CI triggered)
git checkout staging
git merge feature/test-ci

# Create PR: staging → main (triggers CI)
gh pr create --base main --head staging --title "Test CI Pipeline"

📊 Pipeline Status

CI Pipeline Phases:

• ✅ Phase 1: Lint & Validate
• ✅ Phase 2: Unit Tests (Layer 1)
• ✅ Phase 3: Integration Tests (Layer 2)
• ✅ Phase 4: E2E Tests (Layer 3)
• ✅ Phase 5: Docker Build & Test
• ✅ Phase 6: Security Scan (Layer 4)
• ✅ Phase 7: CI Summary

CD Pipeline Phases:

🔐 Security Features

Container Security:

• Cosign Signing: All production images cryptographically signed
• SBOM Generation: Software Bill of Materials for compliance
• Vulnerability Scanning: Trivy scans for known vulnerabilities
• Registry Security: GitHub Container Registry with access controls

Pipeline Security:

• Secret Management: GitHub Secrets for sensitive data
• Branch Protection: Required reviews and status checks
• Audit Trail: Complete deployment history and logs
• Access Control: CODEOWNERS file for code review requirements

📈 Monitoring & Observability

Pipeline Metrics:

• Success Rate: Target >95%
• Average Duration: CI ~30min, CD ~10min
• Parallel Execution: Unit & Integration tests
• Failure Recovery: Automatic retries on transient failures

Production Monitoring:

• Health Checks: Automated endpoint monitoring
• Deployment Verification: Post-deploy validation
• Rollback Capability: Quick rollback on failures
• Performance Tracking: Response time and error rate monitoring

🛠️ Development Workflow

For Developers:

1. Create Feature Branch: git checkout -b feature/your-feature
2. Develop & Test Locally: Run tests before pushing
3. Push to Feature Branch: git push origin feature/your-feature
4. Merge to Staging: Manual merge (no CI triggered)
5. Create PR to Main: This triggers the full CI pipeline

For DevOps:

1. Monitor Pipeline: Watch CI/CD execution
2. Review Security Scans: Address vulnerabilities
3. Manage Deployments: Monitor production deployments
4. Update Pipeline: Maintain and improve workflows

🔧 Local Development

Run Tests Locally:

# Backend tests
cd backend
php artisan test --testsuite=Unit
php artisan test --testsuite=Feature

# Frontend tests  
cd frontend/web
npm run test:unit
npm run test:integration
npx playwright test

# Docker build test
docker build -t jobapp-test .
docker run --rm -p 8080:8080 jobapp-test

Security Scanning:

# Install security tools
brew install syft trivy cosign

# Generate SBOM
syft jobapp-test:latest -o spdx-json

# Vulnerability scan
trivy image jobapp-test:latest

# Sign image
cosign sign jobapp-test:latest
