Jenkins in Cloud: Azure Setup

1. Introduction

Jenkins is a widely used open-source automation server that enables developers to build, test, and deploy applications continuously. Integrating Jenkins with cloud platforms like Azure allows for scalable and flexible CI/CD pipelines.

2. Key Concepts

2.1 Jenkins

Jenkins is a server-side application that facilitates automation through plugins. It supports building, deploying, and automating software development tasks.

2.2 Azure

Azure is a cloud computing service created by Microsoft, offering a range of cloud services, including computing, analytics, storage, and networking.

2.3 Continuous Integration/Continuous Deployment (CI/CD)

CI/CD is a method to deliver apps to customers more frequently by introducing automation into the stages of app development.

3. Setup Process

3.1 Prerequisites

A valid Azure account.
Basic knowledge of Jenkins.
Azure CLI installed on your machine.

3.2 Steps to Set Up Jenkins on Azure

Log in to Azure Portal and create a new Resource Group.
Create a Virtual Machine (VM) with suitable specifications.
SSH into the VM using the terminal.

Install Java on the VM:

sudo apt update
sudo apt install openjdk-11-jdk

Download and install Jenkins:

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

Start Jenkins service:

sudo systemctl start jenkins
sudo systemctl enable jenkins

Open the Jenkins web interface by navigating to http://:8080.
Complete the Jenkins setup wizard and install suggested plugins.
