OVERVIEW

In my previous blog posts, we got to know what Jenkins is and its importance as a continuous integration tool. In this article, we will be going through how to work with Jenkins on an Ubuntu operating system. Let's get right into it.

Quickstart

Step 1:- Install Jenkins and its dependencies

Update the server and install JDK since Jenkins is a Java-based application

sudo apt update sudo apt install default-jdk-headless

Install Jenkins and ensure that it is running

wget -q -O - https://pkg.jenkins.io/debian-stable/jenkins.io.key | sudo apt-key add - sudo sh -c 'echo deb https://pkg.jenkins.io/debian-stable binary/ > \ /etc/apt/sources.list.d/jenkins.list'

sudo apt update sudo apt-get install jenkins sudo systemctl status jenkins

Step 2:- Perform Initial Jenkins setup

Access the public IP address of your Jenkins server from your web browser

 http://<Jenkins-Server-Public-IP-Address-or-Public-DNS-Name>:8080

To ensure Jenkins is securely set up by the administrator, a password has been written in a file on the server but you have to check the file, copy the password and paste it on the Jenkins console before you can continue the Jenkins setup.

Just run `sudo cat /var/lib/jenkins/secrets/initialAdminPassword` on the terminal you're using and get 
the password.

Customize Jenkins by installing suggested plugins.

Create an admin user then you will get your jenkins address.

Then you can start performing your desired project on the jenkins console
