Cara Setup CI/CD dengan GitHub Actions

GitHub Actions memungkinkan kamu otomasi build, test, dan deploy setiap kali push kode. Gratis untuk public repo!

Basic Workflow

Buat file .github/workflows/ci.yml:

name: CI
on:
  push:
    branches: [main]
  pull_request:
    branches: [main]

jobs:
  build:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - uses: actions/setup-node@v4
        with:
          node-version: 20
          cache: npm
      - run: npm ci
      - run: npm run lint
      - run: npm run build
      - run: npm test

Auto Deploy ke VPS

  deploy:
    needs: build
    if: github.ref == 'refs/heads/main'
    runs-on: ubuntu-latest
    steps:
      - name: Deploy via SSH
        uses: appleboy/ssh-action@v1
        with:
          host: ${{ secrets.VPS_HOST }}
          username: root
          key: ${{ secrets.SSH_KEY }}
          script: |
            cd /root/myapp
            git pull
            docker compose up -d --build

Tips

• Simpan secrets di GitHub Settings > Secrets
• Gunakan caching untuk mempercepat build
• Jalankan linter dan tests sebelum deploy
• Notifikasi ke Slack/Discord saat deploy berhasil/gagal

Dengan CI/CD, kamu bisa deploy dengan confident setiap saat.
