cicd-automation（CICD 自动化）

CI/CD Automation Skill

When to Activate

Activate this skill when:

• Creating GitHub Actions workflows
• Setting up automated testing
• Configuring deployment pipelines
• Adding code quality checks to CI
• Automating release processes

Quick Start Workflow

Create .github/workflows/ci.yml:

name: CI

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

jobs:
  test:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4

      - name: Install UV
        run: curl -LsSf https://astral.sh/uv/install.sh | sh

      - name: Add UV to PATH
        run: echo "$HOME/.cargo/bin" >> $GITHUB_PATH

      - name: Install dependencies
        run: uv sync

      - name: Run tests
        run: uv run pytest tests/ -v --cov=src

      - name: Lint with Ruff
        run: uv run ruff check src/ tests/

      - name: Check formatting
        run: uv run black --check src/ tests/

Workflow Structure

.github/
└── workflows/
    ├── ci.yml        # Tests and linting
    ├── release.yml   # Package publishing
    └── deploy.yml    # Deployment

Common Triggers

# Every push and PR
on: [push, pull_request]

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

# Manual trigger
on: workflow_dispatch

# Scheduled (cron)
on:
  schedule:
    - cron: '0 0 * * *'  # Daily at midnight

Testing with Coverage

- name: Run tests with coverage
  run: |
    uv run pytest tests/ \
      --cov=src \
      --cov-report=xml \
      --cov-report=term-missing \
      --junitxml=junit.xml

- name: Upload coverage to Codecov
  uses: codecov/codecov-action@v3
  with:
    files: ./coverage.xml
    fail_ci_if_error: true

Multi-Environment Testing

jobs:
  test:
    runs-on: ${{ matrix.os }}
    strategy:
      matrix:
        os: [ubuntu-latest, macos-latest, windows-latest]
        python-version: ['3.10', '3.11', '3.12']

    steps:
      - uses: actions/checkout@v4

      - uses: actions/setup-python@v5
        with:
          python-version: ${{ matrix.python-version }}

      - name: Install UV
        run: curl -LsSf https://astral.sh/uv/install.sh | sh

      - name: Run tests
        run: uv run pytest tests/

Caching Dependencies

- name: Cache UV dependencies
  uses: actions/cache@v3
  with:
    path: |
      ~/.cache/uv
      .venv
    key: ${{ runner.os }}-uv-${{ hashFiles('**/pyproject.toml') }}
    restore-keys: |
      ${{ runner.os }}-uv-

- name: Install dependencies
  run: uv sync

Secrets in Workflows

- name: Deploy
  env:
    API_KEY: ${{ secrets.ANTHROPIC_API_KEY }}
    DATABASE_URL: ${{ secrets.DATABASE_URL }}
  run: uv run python deploy.py

Setting up secrets:

1. Repository Settings → Secrets and variables → Actions
2. Click "New repository secret"
3. Add name and value

Publishing to PyPI

name: Publish

on:
  release:
    types: [published]

jobs:
  publish:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4

      - name: Install UV
        run: curl -LsSf https://astral.sh/uv/install.sh | sh

      - name: Build package
        run: uv build

      - name: Publish to PyPI
        env:
          UV_PUBLISH_TOKEN: ${{ secrets.PYPI_TOKEN }}
        run: uv publish --token $UV_PUBLISH_TOKEN

Docker Image Build

- name: Build and push Docker image
  uses: docker/build-push-action@v5
  with:
    context: .
    push: true
    tags: user/app:latest,user/app:${{ github.sha }}

Best Practices

DO ✅

• Run tests on every push
• Cache dependencies for speed
• Use matrix for cross-platform testing
• Separate CI from CD workflows
• Use secrets for sensitive data

DON'T ❌

• Skip linting in CI
• Ignore test failures
• Store secrets in code
• Run unnecessary jobs

When to Use CI/CD

Start with:

1. Running tests on every push
2. Code quality checks (lint, format)
3. Security scanning

Add later:

1. Deployment automation
2. Docker builds
3. Documentation generation
