# Deployment Pipeline Design Architecture patterns for multi-stage CI/CD pipelines with approval gates and deployment strategies. ## Purpose Design robust, secure deployment pipelines that balance speed with safety through proper stage organization and approval workflows. ## When to Use - Design CI/CD architecture - Implement deployment gates - Configure multi-environment pipelines - Establish deployment best practices - Implement progressive delivery ## Pipeline Stages ### Standard Pipeline Flow ``` ┌─────────┐ ┌──────┐ ┌─────────┐ ┌────────┐ ┌──────────┐ │ Build │ → │ Test │ → │ Staging │ → │ Approve│ → │Production│ └─────────┘ └──────┘ └─────────┘ └────────┘ └──────────┘ ``` ### Detailed Stage Breakdown 1. **Source** - Code checkout 2. **Build** - Compile, package, containerize 3. **Test** - Unit, integration, security scans 4. **Staging Deploy** - Deploy to staging environment 5. **Integration Tests** - E2E, smoke tests 6. **Approval Gate** - Manual approval required 7. **Production Deploy** - Canary, blue-green, rolling 8. **Verification** - Health checks, monitoring 9. **Rollback** - Automated rollback on failure ## Approval Gate Patterns ### Pattern 1: Manual Approval ```yaml # GitHub Actions production-deploy: needs: staging-deploy environment: name: production url: https://app.example.com runs-on: ubuntu-latest steps: - name: Deploy to production run: | # Deployment commands ``` ### Pattern 2: Time-Bas
