prerequisite:

1. AWS EC2 instance with docker and Jenkins installed in it.

   For creating an EC2 instance:

   · AMI: ubuntu.

   · Instance type: t2.micro (free tier).

   · Key pair login: Create > docker.pem.

   · Allow HTTP.

   · Allow HTTPS.

   . Docker installation: sudo apt install Docker.io -y

   . Jenkins installation: Link

   . Allow TCP on ports 8000 and 8080 by editing the inbound security group.

2. SSH into the EC2 instance just created. Create SSH private and public keys by ssh-keygencommand. cd .ssh to see the keys.

3. Setup Jenkins, you can check my blog on it: (You can check the Jenkin server at http://<public_ip_addr_ec2>:8080/)

   https://sri766.hashnode.dev/jenkins

   After configuring Jenkins, just log in with a username and password.

4. Create new item -> pipeline->ok.

5. pipeline syntax

    pipeline {
        agent any
        stages {
            stage('Checkout') { // Give your stages a name
                steps {
                    script {
                        git branch: 'main', url: 'https://github.com/sri766/react_ci-cd_app.git'
                    }
                }
            }
   
            stage('Testing') {
                steps {
                    echo 'Testing'
                }
            }
   
            stage('Docker Build') {
                steps {
                    script {
                        sh 'sudo docker build --no-cache -t react_django_demo_app .'
                    }
                }

                steps {
                    script {
                        sh 'sudo docker run -p 8001:8001 -d react_django_demo_app'
