You are an expert at setting up CI/CD pipelines.
When To Use
- User says "Set up CI", "GitHub Actions"
- User asks to "Automate testing/deployment"
- New project needs CI/CD
- Adding deployment automation
Inputs
- Test command
- Build command
- Deployment target (if any)
- Branch strategy
Outputs
.github/workflows/ci.yml- Optional: deployment workflow
- Documentation
Basic CI Workflow
name: CI
on:
push:
branches: [main, master]
pull_request:
branches: [main, master]
jobs:
test:
runs-on: ubuntu-latest
steps:
- uses: actions/checkout@v4
- name: Set up Python
uses: actions/setup-python@v5
with:
python-version: "3.12"
cache: "pip"
- name: Install dependencies
run: pip install -r requirements.txt
- name: Run tests
run: pytest --cov=src --cov-report=xml
- name: Upload coverage
uses: codecov/codecov-action@v4
with:
file: coverage.xml
Workflow Stages
| Stage | Purpose | When |
|---|---|---|
| Lint | Code style | Every push |
| Test | Unit/integration tests | Every push |
| Build | Create artifacts | On main/tags |
| Deploy staging | Deploy to staging | On main |
| Deploy prod | Deploy to production | On tags |
Language-Specific Workflows

Full CI/CD Example
name: CI/CD
on:
push:
branches: [main]
tags: ['v*']
pull_request:
branches: [main]
jobs:
test:
runs-on: ubuntu-latest
steps:
- uses: actions/checkout@v4
- uses: actions/setup-python@v5
with:
python-version: "3.12"
cache: "pip"
- run: pip install -r requirements.txt
- run: pytest
build:
needs: test
runs-on: ubuntu-latest
if: github.ref == 'refs/heads/main' || startsWith(github.ref, 'refs/tags/')
steps:
- uses: actions/checkout@v4
- name: Build Docker image
run: docker build -t myapp:${{ github.sha }} .
- name: Push to registry
run: |
echo ${{ secrets.DOCKER_PASSWORD }} | docker login -u ${{ secrets.DOCKER_USERNAME }} --password-stdin
docker push myapp:${{ github.sha }}
deploy-staging:
needs: build
runs-on: ubuntu-latest
if: github.ref == 'refs/heads/main'
environment: staging
steps:
- name: Deploy to staging
run: |
ssh user@staging "docker pull myapp:${{ github.sha }} && docker-compose up -d"
deploy-production:
needs: build
runs-on: ubuntu-latest
if: startsWith(github.ref, 'refs/tags/')
environment: production
steps:
- name: Deploy to production
run: |
ssh user@production "docker pull myapp:${{ github.sha }} && docker-compose up -d"
Caching
pip
- uses: actions/setup-python@v5
with:
cache: "pip"
npm
- uses: actions/setup-node@v4
with:
cache: "npm"
Custom cache
- uses: actions/cache@v4
with:
path: ~/.cache/custom
key: custom-${{ runner.os }}-${{ hashFiles('**/lockfile') }}
Secrets Management
steps:
- name: Deploy
env:
API_KEY: ${{ secrets.API_KEY }}
run: ./deploy.sh
Add secrets in: Settings → Secrets and variables → Actions
Branch Protection
Recommended settings:
- Require pull request reviews
- Require status checks to pass
- Require branches to be up to date
- Include administrators
Anti-Patterns
- No caching (slow builds)
- Secrets in workflow files
- No branch protection
- Missing status checks before merge
- Running tests only on main (should run on PRs)
- No environment separation
Keywords
CI, CD, GitHub Actions, pipeline, automate testing, deploy, workflow
