Install Jenkins in Azure VM using Docker | How to Install Jenkins in Azure VM using Docker Compose on Ubuntu 22.0.4 | Install Jenkins using Docker-Compose

Jenkins is an open source continuous integration/continuous delivery and deployment (CI/CD) automation software DevOps tool written in the Java programming language. It is used to implement CI/CD workflows, called pipelines.

How to setup Jenkins using Docker Compose?

Jenkins is continuous integration server. It is open source and Java based tool. Jenkins can be setup using Docker Compose with less manual steps.

What is Docker Compose?

Compose is a tool for defining and running multi-container Docker applications. With Compose, you use a YAML file to configure your application’s services. Then, with a single command, you create and start all the services from your configuration. Since Docker Compose lets you configure related containers in a single YAML file, you get the same Infrastructure-as-Code abilities as Kubernetes. But they come in a simpler system that’s more suited to smaller applications that don’t need Kubernetes’ resiliency and scaling.

 

The purpose of docker-compose is to function as docker cli but to issue multiple commands much more quickly. To make use of docker-compose, you need to encode the commands you were running before into a docker-compose.yml file

 

Run docker-compose up and Compose starts and runs your entire app.

Pre-requisites:

• New Ubuntu 22.0.4 VM setup and running with at least 2 GB RAM in Azure Cloud
  
• Port 8080 is opened in Inbound port rule in Networking

Change Host Name to Jenkins

sudo hostnamectl set-hostname Jenkins

Perform system update

sudo apt update

Install Docker-Compose

sudo apt install docker-compose -y

Create docker-compose.yml

this yml has all configuration for installing Jenkins.

sudo vi docker-compose.yml 

(Copy the below code high-lighted in yellow color)

version: '3'

services:

  jenkins:

    image: jenkins/jenkins:lts

    restart: always

    privileged: true

    user: root

    ports:

      - 8080:8080

      - 50000:50000

    container_name: jenkins

    volumes:

      - /home/ubuntu/jenkins_compose/jenkins_configuration:/var/jenkins_home

      - /var/run/docker.sock:/var/run/docker.sock

Save the file by entering :wq!

Execute Docker compose command:

sudo docker-compose up -d 

Make sure Jenkins is up and running by checking the logs

sudo docker-compose logs --follow

Once you see the message, that's it. Jenkins is been installed successfully. press control C and enter.

Now access Jenkins UI by going to browser and enter public dns name with port 8080

Now to go to browser --> http://your_jenkins_publicdns_name:8080/

You can get the Admin password from above command as well.

Enter Admin Password

Enter the password and Click on continue.

Then click on install suggested plug-ins. 

Also create user name and password.

enter everything as admin. at least user name as admin password as admin

Click on Save and Finish. Click on start using Jenkins. Now you should see a screen like below:

That's it. You have setup Jenkins successfully using Docker Compose.

To Clean Up Resources

sudo docker compose down

This should stop the Jenkins container that is running.
