CI/CD 워크플로 구축

CI/CD 시작하기

CI/CD가 중요한 이유

GitHub Actions: 핵심 개념

첫 CI 워크플로 만들기

name: Node.js CI

on: [push]

jobs:
  build:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - name: Set up Node.js
        uses: actions/setup-node@v4
        with:
          node-version: '18'
      - name: Install dependencies
        run: npm install
      - name: Build project
        run: node build.js

빌드 스크립트 시뮬레이션

console.log("Starting project build...");
console.log("  - Compiling source files...");
console.log("  - Bundling assets for deployment...");
console.log("Build process finished successfully!");

자동화된 테스트 추가

name: Node.js CI

on: [push]

jobs:
  build:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - name: Set up Node.js
        uses: actions/setup-node@v4
        with:
          node-version: '18'
      - name: Install dependencies
        run: npm install
      - name: Run tests
        run: node test.js
      - name: Build project
        run: node build.js

테스트 스크립트 시뮬레이션

console.log("Running automated tests...");
const allTestsPass = Math.random() > 0.1; // Simulate 90% chance of passing

if (allTestsPass) {
  console.log("All 12 tests passed successfully!");
} else {
  console.error("Tests failed! Please fix the errors.");
  process.exit(1); // Exit with a non-zero code to indicate failure
}

지속적 배포(CD) 소개

간단한 CD 워크플로

name: Deploy to Production

on:
  push:
    tags:
      - 'v*.*.*' # Triggers on tags like v1.0.0, v1.2.3

jobs:
  deploy:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - name: Simulate deployment
        run: |
          echo "Deploying application to production server..."
          echo "Version: ${{ github.ref_name }}"
          echo "Deployment complete!"
          # In a real scenario, you'd use a deployment action here
          # e.g., aws-actions/configure-aws-credentials, appleboy/ssh-action
