GitHub Actions CI/CD 기본 설정법

GitHub Actions 기본 워크플로우:

# .github/workflows/ci.yml
name: CI

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

jobs:
  test:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v3
      - uses: actions/setup-node@v3
        with:
          node-version: 18
          cache: npm
      - run: npm ci
      - run: npm test
      - run: npm run build

  deploy:
    needs: test
    if: github.ref == 'refs/heads/main'
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v3
      - run: npm ci && npm run build
      - name: Deploy
        run: |
          rsync -avz ./dist/ user@server:/var/www/

핵심:

• on — 트리거 조건 (push, PR, schedule 등)
• jobs — 병렬 실행 가능한 작업 단위
• needs — 의존성 (test 통과 후 deploy)
• secrets — Settings → Secrets에 민감 정보 저장
