Introduction

If you’re still manually deploying your applications, you’re not just slow—you’re increasing your risk of errors, burning out your team, and falling behind competitors who ship features 10x faster.

The good news? Implementing CI/CD (Continuous Integration/Continuous Deployment) doesn’t require months of planning or a dedicated DevOps team. I’ve helped dozens of companies go from manual deployments to fully automated pipelines in less than a week.

In this guide, you’ll learn exactly how to implement CI/CD in 5 days, with real code examples, tool recommendations, and best practices that actually work in production.


Prerequisites: What You Need Before Starting

Before diving into CI/CD, make sure you have these basics in place:

  • Version control: Your code is in Git (GitHub, GitLab, or Bitbucket)
  • Some tests: Even basic unit tests are better than none (we’ll add more)
  • Cloud/server access: Somewhere to deploy (AWS, Azure, GCP, or even a VPS)
  • Basic Docker knowledge: Optional but highly recommended

Don’t have tests yet? Start with smoke tests—just verify your app starts and responds. You can add comprehensive tests later.


Day 1-2: Setting Up Continuous Integration (CI)

Choose Your CI Tool

For most teams, I recommend:

  • GitHub Actions: If you’re on GitHub (easiest to start)
  • GitLab CI: If you’re on GitLab (excellent built-in features)
  • Jenkins: If you need ultimate flexibility or on-premises deployment

For this guide, I’ll use GitHub Actions because it’s free for public repos and has 2,000 free minutes/month for private repos.

Create Your First CI Pipeline

Create .github/workflows/ci.yml in your repository:

name: CI Pipeline

on:
  push:
    branches: [ main, develop ]
  pull_request:
    branches: [ main ]

jobs:
  test:
    runs-on: ubuntu-latest

    steps:
    - uses: actions/checkout@v3

    - name: Set up Node.js
      uses: actions/setup-node@v3
      with:
        node-version: '18'
        cache: 'npm'

    - name: Install dependencies
      run: npm ci

    - name: Run linter
      run: npm run lint

    - name: Run tests
      run: npm test

    - name: Build application
      run: npm run build

What this does:

  • Triggers on every push to main/develop and all pull requests
  • Runs your linter to catch code quality issues
  • Runs all tests to verify nothing broke
  • Builds your application to catch build errors early

Pro Tip: Add a badge to your README so everyone can see CI status at a glance.


Day 3-4: Implementing Continuous Deployment (CD)

Deployment Strategies

Choose the right strategy for your application:

  • Blue-Green: Two identical environments, switch traffic instantly (zero downtime)
  • Rolling: Gradually replace old instances with new ones (good for stateful apps)
  • Canary: Deploy to small % of users first, then rollout (safest for critical apps)

Deploy to Staging First

Never deploy directly to production. Always use a staging environment that mirrors production.

Add deployment to your workflow:

  deploy-staging:
    needs: test
    runs-on: ubuntu-latest
    if: github.ref == 'refs/heads/develop'

    steps:
    - uses: actions/checkout@v3

    - name: Configure AWS credentials
      uses: aws-actions/configure-aws-credentials@v2
      with:
        aws-access-key-id: ${{ secrets.AWS_ACCESS_KEY_ID }}
        aws-secret-access-key: ${{ secrets.AWS_SECRET_ACCESS_KEY }}
        aws-region: us-east-1

    - name: Login to Amazon ECR
      id: login-ecr
      uses: aws-actions/amazon-ecr-login@v1

    - name: Build and push Docker image
      env:
        ECR_REGISTRY: ${{ steps.login-ecr.outputs.registry }}
        IMAGE_TAG: ${{ github.sha }}
      run: |
        docker build -t $ECR_REGISTRY/myapp:$IMAGE_TAG .
        docker push $ECR_REGISTRY/myapp:$IMAGE_TAG

    - name: Deploy to ECS Staging
      run: |
        aws ecs update-service \
          --cluster staging-cluster \
          --service myapp-service \
          --force-new-deployment

Production Deployment with Approval

Production deployments should require manual approval:

  deploy-production:
    needs: test
    runs-on: ubuntu-latest
    if: github.ref == 'refs/heads/main'
    environment:
      name: production
      url: https://myapp.com

    steps:
    # Same steps as staging, but deploy to production
    - name: Deploy to ECS Production
      run: |
        aws ecs update-service \
          --cluster production-cluster \
          --service myapp-service \
          --force-new-deployment

Important: Configure branch protection rules on main branch to require:

  • Pull request reviews (at least 1 approval)
  • All CI checks passing
  • No force pushes

Day 5: Safety Checks and Rollback Strategy

Health Checks

Always verify deployment succeeded before considering it done:

    - name: Wait for deployment
      run: |
        aws ecs wait services-stable \
          --cluster production-cluster \
          --services myapp-service

    - name: Health check
      run: |
        for i in {1..10}; do
          if curl -f https://myapp.com/health; then
            echo "Health check passed"
            exit 0
          fi
          echo "Waiting for health check... ($i/10)"
          sleep 10
        done
        echo "Health check failed"
        exit 1

Automated Rollback

If deployment fails, automatically rollback:

    - name: Rollback on failure
      if: failure()
      run: |
        echo "Deployment failed, rolling back..."
        aws ecs update-service \
          --cluster production-cluster \
          --service myapp-service \
          --task-definition myapp:${{ env.PREVIOUS_VERSION }}

Best Practices for Production CI/CD

1. Keep Secrets Secure

  • Never commit credentials to Git
  • Use GitHub Secrets or similar encrypted storage
  • Rotate secrets regularly
  • Use least-privilege IAM roles

2. Fast Feedback Loop

  • Keep CI pipeline under 10 minutes
  • Run fast tests first (unit), slow tests later (E2E)
  • Cache dependencies aggressively
  • Parallelize test execution

3. Monitoring and Alerts

Set up alerts for:

  • Failed deployments
  • Failed health checks
  • Error rate spikes after deployment
  • Performance degradation

4. Database Migrations

Handle schema changes carefully:

  • Always make migrations backward-compatible
  • Run migrations before code deployment
  • Use a migration tool (Flyway, Liquibase, or framework-specific)
  • Test migrations in staging first

Real-World Results

Before CI/CD:

  • Deployments: 1-2 per week, taking 2-4 hours each
  • Deployment errors: 30-40% of deployments had issues
  • Rollback time: 30-60 minutes
  • Developer anxiety: High during deployment days

After CI/CD:

  • Deployments: 10+ per day, taking 5-10 minutes each
  • Deployment errors: <5% (caught by automated tests)
  • Rollback time: 2-3 minutes (automated)
  • Developer confidence: High (deployments are boring, which is good!)

Common Pitfalls to Avoid

  1. Skipping tests to “move faster” – This always backfires with production bugs
  2. No staging environment – Testing in production is expensive
  3. Manual approval for every deploy – Defeats the purpose of automation
  4. Not monitoring deployments – Silent failures are the worst failures
  5. Over-engineering from day 1 – Start simple, add complexity as needed

Conclusion

Implementing CI/CD in less than a week is absolutely achievable if you follow a structured approach:

  1. Days 1-2: Set up CI with automated testing and builds
  2. Days 3-4: Implement CD to staging and production
  3. Day 5: Add safety checks and rollback mechanisms

The key is to start simple and iterate. Your first pipeline doesn’t need to be perfect—it just needs to work. You can add sophistication (blue-green deployments, canary releases, advanced monitoring) incrementally.

Next steps:

  1. Pick your CI/CD tool today
  2. Create a basic pipeline for one application
  3. Test it thoroughly in staging
  4. Monitor your first production deployment closely
  5. Document the process for your team
