Node-ci-demo

A simple Node.js project to demonstrate ### Build the Docker Image

To build the Docker image locally, run the following command in the project's root directory:

docker build -t node-ci-demo .

Run the Docker Container

To run the Docker container locally, use the following command:

docker run -d -p 3000:3000 --name node-ci-demo node-ci-demo
```ub Actions, Docker, and AWS.

## Prerequisites

- Node.js version 20.0.0 or higher
- Docker (for containerization)

## Installation

First, ensure you have the correct Node.js version installed. You can check your version with:

```bash
node --version

Then install the dependencies by running:

npm install

Running the Application

To start the application, run:

npm start

The application will be available at http://localhost:3000.

Running Tests

To run the tests, use:

npm test

CI/CD Pipeline

This project uses GitHub Actions for continuous integration and deployment. The pipeline:

1. Runs on Node.js 20.x and 21.x
2. Installs dependencies
3. Runs linting checks
4. Executes tests
5. Builds and pushes Docker image
6. Deploys to AWS EC2

Docker

This project can be containerized using Docker.

Build the Docker Image

To build the Docker image locally, run the following command in the project's root directory:

docker build -t node-ci-demo:latest .

Run the Docker Container

To run the Docker container locally, use the following command:

docker run -d -p 3000:3000 --name node-ci-demo node-ci-demo:latest

To stop and remove the container (if you need to rebuild and run again):

docker stop node-ci-demo
docker rm node-ci-demo

The application will be available at http://localhost:3000.

CI/CD

This project is configured with a CI/CD pipeline using GitHub Actions. The workflow is defined in .github/workflows/node.yml.

The pipeline includes the following jobs:

• build: Installs dependencies and runs tests for different Node.js versions.
• deploy: Deploys the application to an AWS EC2 instance using Docker.

The deployment process involves:

1. Connecting to the EC2 instance via SSH.
2. Stopping and removing any existing Docker containers.
3. Pulling the latest code from the GitHub repository.
4. Building a new Docker image.
5. Running a new Docker container with the updated image.
