How do I understand core concepts and set up?

# Step 1: Grasp Fundamentals GitHub Actions automates workflows triggered by events like pushes or pull requests. Key concepts: - **Workflows**: YAML files in `.github/workflows/` defining automation. - **Events**: Triggers (e.g., `push`, `pull_request`). - **Jobs**: Sets of steps running on runners (e.g., `ubuntu-latest`). - **Steps**: Tasks using `run` (shell commands) or `uses` (actions). - **Actions**: Reusable units from Marketplace or custom. - **Runners**: GitHub-hosted VMs (Linux, Windows, macOS). ## Prerequisites - GitHub account (free). - Create a new public repository (Actions free for public repos). Go to [docs.github.com/en/actions](https://docs.github.com/en/actions) and read 'Understanding GitHub Actions'. Create a repo: `https://github.com/new` > Name it `actions-learning` > Public > Create.

How do I create your first workflow?

# Step 2: Build Hello World Workflow Follow official quickstart: 1. In your repo, create `.github/workflows/demo.yml`. 2. Add this YAML: ```yaml name: GitHub Actions Demo on: [push] jobs: Explore-GitHub-Actions: runs-on: ubuntu-latest steps: - run: echo "Hello, ${{ github.actor }}!" - name: Check out repository code uses: actions/checkout@v5 - run: echo "Repo: ${{ github.repository }}" - run: ls ${{ github.workspace }} ``` 3. Commit to `main`. 4. View run: Actions tab > Select workflow > See logs. Contexts like `${{ github.actor }}` provide runtime data.

How do I customize with jobs, steps, and actions?

# Step 3: Add Multiple Jobs and Marketplace Actions Extend demo: ```yaml name: Multi-Job Demo on: [push] jobs: checkout: runs-on: ubuntu-latest steps: - uses: actions/checkout@v5 setup-node: needs: checkout runs-on: ubuntu-latest steps: - uses: actions/setup-node@v5 with: node-version: '20' test: needs: setup-node runs-on: ubuntu-latest steps: - uses: actions/checkout@v5 - run: npm test ``` - `needs`: Job dependency. - `uses`: Marketplace actions (e.g., `actions/setup-node@v5`). - Explore [Marketplace](https://github.com/marketplace?type=actions). Commit and observe parallel/sequential runs.

How do I build continuous integration pipeline?

# Step 4: Implement CI for Code Testing Add Node.js example (adapt for your lang): 1. Add `package.json` with scripts: `{ "test": "echo 'Tests pass'" }`. 2. Workflow `.github/workflows/ci.yml`: ```yaml name: CI on: [push, pull_request] jobs: test: runs-on: ubuntu-latest steps: - uses: actions/checkout@v5 - uses: actions/setup-node@v5 with: { node-version: 20 } - run: npm ci - run: npm test ``` Triggers on push/PR. See [Node.js tutorial](https://docs.github.com/en/actions/automating-builds-and-tests/building-and-testing-nodejs). Test: Push changes, create PR, verify green checks.

How do I deploy with continuous delivery?

# Step 5: Add CD for Deployment Simple deploy to GitHub Pages (static site): 1. Add `index.html`. 2. Workflow `.github/workflows/cd.yml`: ```yaml name: Deploy to Pages on: push: branches: [main] permissions: contents: read pages: write id-token: write jobs: deploy: runs-on: ubuntu-latest steps: - uses: actions/checkout@v5 - uses: actions/configure-pages@v5 - uses: actions/upload-pages-artifact@v3 with: { path: . } deploy: needs: upload-artifact uses: actions/deploy-pages@v4 ``` See Pages tab after push. Explore [deployment docs](https://docs.github.com/en/actions/deployment/deploying-to-your-cloud-provider). Advanced: Secrets for AWS/Docker via Settings > Secrets.

Step 1: Grasp Fundamentals

GitHub Actions automates workflows triggered by events like pushes or pull requests. Key concepts:

Workflows: YAML files in .github/workflows/ defining automation.
Events: Triggers (e.g., push, pull_request).
Jobs: Sets of steps running on runners (e.g., ubuntu-latest).
Steps: Tasks using run (shell commands) or uses (actions).
Actions: Reusable units from Marketplace or custom.
Runners: GitHub-hosted VMs (Linux, Windows, macOS).

Prerequisites

GitHub account (free).
Create a new public repository (Actions free for public repos).

Go to docs.github.com/en/actions and read 'Understanding GitHub Actions'.

Create a repo: https://github.com/new > Name it actions-learning > Public > Create.

Why this step matters:

-Builds foundation to write effective workflows
-Enables automation in real projects without confusion

30-60 minutes

GitHub account, Web browser, GitHub repository

Definition of Done

•Explain workflow, job, step, action, runner in own words
•Created a public repo with Actions enabled

Common Mistakes to Avoid

❌ Forgetting to enable Actions in repo settings

→Go to Settings > Actions > General > Allow all actions

❌ Using private repo without billing setup

→Start with public repo for free minutes
