Project Setup using below tools

  1. Maven
  2. Git Hub
  3. Jenkins
  4. Docker

Step-1 : Jenkins Server Setup in Linux VM

  1. Create Ubuntu VM using AWS EC2 (t2.medium) with atleast 50 GB storage
  2. Enable 8080 Port Number in Security Group Inbound Rules
  3. Connect to VM using MobaXterm
  4. Install Java
sudo apt update
sudo apt install fontconfig openjdk-17-jre
java -version
  1. Install Jenkins
sudo wget -O /usr/share/keyrings/jenkins-keyring.asc \
  https://pkg.jenkins.io/debian-stable/jenkins.io-2023.key
echo deb [signed-by=/usr/share/keyrings/jenkins-keyring.asc] \
  https://pkg.jenkins.io/debian-stable binary/ | sudo tee \
  /etc/apt/sources.list.d/jenkins.list > /dev/null
sudo apt-get update
sudo apt-get install jenkins
  1. Start Jenkins
sudo systemctl enable jenkins
sudo systemctl start jenkins
  1. Verify Jenkins
sudo systemctl status jenkins

NOTE: below are few additional commands for understanding purpose

To stop, restart, disable/enable jenkins on system start-up

sudo systemctl stop jenkins
sudo systemctl restart jenkins
sudo systemctl disable jenkins
sudo systemctl enable jenkins
  1. Access jenkins server in browser using VM public ip
http://public-ip:8080/
  1. Copy jenkins admin pwd
sudo cat /var/lib/jenkins/secrets/initialAdminPassword
  1. Create Admin Account & Install Required Plugins in Jenkins

Step-2 : Configure Maven as Global Tool in Jenkins

  1. Manage Jenkins -> Tools -> Maven Installation -> Add maven

Step-3 : Setup Docker in Jenkins

curl -fsSL get.docker.com | /bin/bash
sudo usermod -aG docker jenkins
sudo usermod -aG docker ubuntu
sudo systemctl restart jenkins
sudo docker version

Step - 4 : Create Jenkins Job

  • Stage-1 : Clone Git Repo
  • Stage-2 : Maven Build
  • Stage-3 : Create Docker Image
  • Stage-4 : Create Docker Container

Step - 5 : Trigger Jenkins Job

Step - 6 : Enable host port in security group inbound rules

Step - 7 : Access Application in Browser

  • We should be able to access our application

URL : http://public-ip:port/

We are done with our Setup

Step - 8 : After your practise, delete resources we have used in AWS Cloud to avoid billing
