CI/CD Flow

Developer → Git Push → CI → Tests → Build → Deploy → Production

Example: GitHub Actions

Step 1 — Create workflow

.github/workflows/deploy.yml

name: Deploy App

on:
  push:
    branches: [ "main" ]

jobs:
  build:
    runs-on: ubuntu-latest

    steps:
    - name: Checkout
      uses: actions/checkout@v3

    - name: Build Docker image
      run: docker build -t myapp .

    - name: Run tests
      run: echo "Tests passed"

    - name: Deploy
      run: echo "Deploying..."

Popular Tools

• GitHub Actions
• GitLab CI/CD
• Jenkins
• CircleCI

Pro Tips

• Always run tests before deploy
• Use environment variables (no secrets in code)
• Keep pipelines simple at first

Real Example Workflow

1. Push code
2. Pipeline starts
3. Tests run
4. Docker image builds
5. Deploy to server

👉 Fully automated.
