1. Introduction to Continuous Integration (CI)
- Define Continuous Integration (CI) and its importance in modern software development.
- Benefits of CI: early bug detection, reduced integration issues, improved code quality.
- Briefly introduce GitHub Actions as a CI/CD tool integrated with GitHub.
2. Setting Up Your GitHub Repository
- Prerequisites: GitHub account, a sample project repository.
-
Steps to create or clone a repository:
git clone https://github.com/your-username/your-repository.git cd your-repository
3. Introduction to GitHub Actions
- Overview of GitHub Actions, workflows, and actions.
- Explain the concept of workflows, jobs, and steps in GitHub Actions.
4. Creating Your First GitHub Actions Workflow
- Creating a
.github/workflows
directory in your project. -
Adding a basic workflow file:
# .github/workflows/ci.yml name: CI on: push: branches: [ main ] pull_request: branches: [ main ] jobs: build: runs-on: ubuntu-latest steps: - name: Checkout code uses: actions/checkout@v2 - name: Set up Node.js uses: actions/setup-node@v2 with: node-version: '14' - name: Install dependencies run: npm install - name: Run tests run: npm test
-
Explanation of each section:
-
name
: The name of the workflow. -
on
: Events that trigger the workflow (e.g., push tomain
branch, pull requests). -
jobs
: The job configuration. -
runs-on
: The environment for the job (e.g.,ubuntu-latest
). -
steps
: Steps to execute in the job (e.g., checkout code, set up Node.js, install dependencies, run tests).
-
5. Running Your Workflow
-
Pushing changes to trigger the workflow:
git add . git commit -m "Add CI workflow" git push origin main
Viewing the workflow run in the GitHub Actions tab of your repository.
6. Customizing Your Workflow
- Adding more steps to the workflow, such as linting or building the project.
-
Example of adding a lint step:
- name: Run linter run: npm run lint
Configuring notifications for build failures and successes.
7. Best Practices for CI/CD Pipelines
- Keep workflows fast and efficient.
- Run tests in parallel if possible.
- Use caching to speed up workflows (e.g., caching
node_modules
). - Secure sensitive data using GitHub Secrets.
8. Advanced GitHub Actions Features
- Using matrix builds to test against multiple environments.
-
Example of a matrix build:
jobs: build: runs-on: ubuntu-latest strategy: matrix: node-version: [10, 12, 14] steps: - name: Checkout code uses: actions/checkout@v2 - name: Set up Node.js uses: actions/setup-node@v2 with: node-version: ${{ matrix.node-version }} - name: Install dependencies run: npm install - name: Run tests run: npm test
Using reusable workflows and composite actions to DRY (Don't Repeat Yourself).
