Assignment 4 Training Document: Deploying a Simple Application with GitHub Actions

Objective: Demonstrate the use of GitHub Actions to automate the deployment of a simple application.
Task:
Use the existing JavaScript program (from Assignment 1).
Write a GitHub Action workflow file (.github/workflows/deploy.yml) that:
Runs tests using Jest (from Assignment 2).
Lints the code (using a tool like ESLint).
Deploys the application to a static hosting platform (e.g., GitHub Pages or Netlify).
Steps:
Add an ESLint configuration to the repository.
Configure the GitHub Action to:
Trigger on a push to the main branch.
Run Jest and ESLint in parallel.
Deploy to a static hosting service if tests and lint checks pass.
Deliverable:
A working GitHub Action workflow file.
A short report (1-2 pages) explaining the steps and how GitHub Actions automate the CI/CD pipeline.
⁠

Course Project: Comprehensive CI/CD Pipeline

Objective: Create a small CI/CD pipeline demonstrating all the learned components: code quality, testing, and deployment.
Task:
Use the JavaScript application enhanced in previous assignments.
Extend the CI/CD pipeline to include:
Building a Docker image for the application.
Pushing the Docker image to Docker Hub.
Deploying the application on a cloud platform (e.g., Heroku or AWS Elastic Beanstalk).
Steps:
Step 1: Write a Dockerfile for the application.
Step 2: Update the GitHub Action workflow to:
Build and test the application.
Build and push a Docker image to Docker Hub.
Trigger a deployment using the Docker image.
Step 3: Provide a README.md with clear instructions for running the project.
Deliverable:
The completed project repository with:
A functional GitHub Actions pipeline.
A Dockerfile.
A brief video (optional) demonstrating the workflow in action.
A summary report discussing the CI/CD pipeline and its components.
⁠

Key Considerations:

Keep all configurations simple and beginner-friendly.
Use public platforms and free-tier services to avoid complexities.
Provide students with example files (e.g., basic Dockerfile, GitHub Actions YAML, and ESLint configurations).
