Task-01: README Documentation for CI/CD Pipeline

Project Title: Node.js CI/CD Pipeline with Docker, Java, and Jenkins

Overview:

This project sets up a continuous integration and continuous deployment (CI/CD) pipeline for a Node.js application using Docker, Java, and Jenkins on an AWS EC2 instance. Follow the steps below to replicate the setup.

Steps:

1. Launch an EC2 Instance:Launch an EC2 instance on AWS with an Amazon Linux 2 AMI / Ubuntu.

2. Connect to EC2 Instance:Connect to your EC2 instance using SSH.

3. Install Docker:bash

• sudo yum update -y sudo apt-get install docker sudo service docker start sudo usermod -a -G docker ec2-user

• Install Java:bash

• sudo yum install java-1.8.0-openjdk -y

• Install Jenkins:Download and install Jenkins from the official Jenkins website.Access Jenkins dashboard in your web browser.

• Create Jenkins Job:Create a new job, name it, and select "Pipeline" as the job type.In the job configuration, select "Pipeline script" and paste the provided script.

• Configure GitHub Webhook:Save the job and go to its configuration page.Under "Build triggers," select "GitHub hook trigger for GITScm polling."

• Create GitHub Webhook:In your GitHub repository settings, navigate to "Webhooks" and create a new webhook.Set the payload URL to http://<jenkins-host>:<jenkins-port>/GitHub-webhook/.

• Create Docker Compose File:Create a docker-compose.yml file in the project root with the provided content.yaml

1. version: '3.9' services: web: build: . ports: - "8000:8000"

2. Commit and Trigger Pipeline:Commit changes to your GitHub repository and wait for Jenkins to trigger the pipeline automatically.

3. Access Deployed Application:Once the pipeline completes successfully, your application should be accessible at http://<publicip>:8000/.

Conclusion:

Congratulations! You have successfully set up a CI/CD pipeline for your Node.js application.
