How do I master ci/cd fundamentals?

# Understand CI/CD Core Concepts CI/CD stands for Continuous Integration (CI) and Continuous Delivery/Deployment (CD). CI merges code changes frequently with automated builds and tests. CD automates delivery to production. ## Key Resources to Read: - [GitHub: What is CI/CD?](https://github.com/resources/articles/ci-cd) 42 0 - [GitHub Actions Concepts](https://docs.github.com/en/actions/learn-github-actions/understanding-github-actions) 83 **Stages in a Pipeline:** Source → Build → Test → Deploy → Monitor. **Events:** Triggers like push, pull_request. **Jobs & Steps:** Parallel jobs with sequential steps using YAML.

How do I set up a github repository?

# Prepare Your Project Repo 1. Sign up/log in at [github.com](https://github.com). 2. Create a new repository (e.g., `my-cicd-demo`), public for free Actions minutes. 3. Add a simple app: Create `index.html`: ```html Hello CI/CD! ``` 4. Commit and push. **Optional:** Add Node.js app for later steps: - Create `package.json`: ```json {"name":"cicd-demo","version":"1.0.0","scripts":{"test":"echo \"Success\" && exit 0"},"devDependencies":{}} ``` - Commit.

How do I create your first workflow?

# Build Basic GitHub Actions Workflow Follow official quickstart: 84 1. In repo, create `.github/workflows/demo.yml`. 2. Paste this YAML: ```yaml name: CI Demo on: [push] jobs: explore: runs-on: ubuntu-latest steps: - uses: actions/checkout@v5 - run: echo "Hello from GitHub Actions!" - run: ls -la ``` 3. Commit to `main`. 4. Go to **Actions** tab → See green checkmark run. **View logs:** Click workflow → Job → Expand steps.

How do I add build and test stages?

# Enhance Pipeline with CI Extend `demo.yml`: ```yaml name: CI Pipeline on: [push, pull_request] jobs: build-test: runs-on: ubuntu-latest steps: - uses: actions/checkout@v5 - name: Setup Node uses: actions/setup-node@v5 with: node-version: '20' - run: npm ci - run: npm test ``` 1. Commit changes. 2. Create PR to test `pull_request` trigger. 3. Verify job succeeds with tests. **For HTML site:** Add lint step with `uses: actions/setup-node` and simple test.

How do I implement continuous deployment?

# Complete CD with Deployment For static site to GitHub Pages: Update `demo.yml`: ```yaml deploy: needs: build-test runs-on: ubuntu-latest if: github.ref == 'refs/heads/main' steps: - uses: actions/checkout@v5 - name: Deploy uses: peaceiris/actions-gh-pages@v4 with: github_token: ${{ secrets.GITHUB_TOKEN }} publish_dir: ./ ``` 1. Enable Pages in Settings > Pages > Source: GitHub Actions. 2. Push to `main` → See deployment. 3. Access at `https:// .github.io/ `. **Scale up:** Add Docker build or cloud deploy later.
