How to Install Jenkins using Docker Compose

Jenkins and Docker sync well together. Cloud containers are one powerful tool for building software in various environments; moreover, Jenkins is the most suitable tool to run inside a container. 

Although the frequently occurring questions are: 

  • How do you manage a Jenkins controller and agents together in Docker? 
  • What if the container crashes? And 
  • How do you back up the data after Jenkins is containerized? 

This article answers all your questions with the clarity of how to install Jenkins the right way. Using Docker compose will undoubtedly make things faster and reusable. So let’s get started with the basic answers. 

What is Jenkins?

Jenkins is a self-contained, open-source automation tool that can be used to automate all tasks related to building, testing, and delivering or deploying software. Jenkins is synonymous with continuous integration and continuous delivery (CI/CD).

The below image shows Jenkins integration with various DevOps tools.

Run these commands in terminal

Change Host Name to Jenkins

> sudo hostname Jenkins

Install docker-compose

> sudo apt update

> sudo apt-get install docker-compose -y

Check version of docker by command 

> docker-compose --version

Add current user to the docker group

> sudo usermod -aG docker $USER

 Create Directory

> mkdir ~/jenkins

Jenkins setup

Create docker-compose.yml fileExecute yaml file

> sudo vi docker-compose.yml

version: '3.3'



image: jenkins/jenkins:lts

restart: unless-stopped

privileged: true

user: root


- 8080:8080

container_name: jenkins


- ~/jenkins:/var/jenkins_home

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

- /usr/local/bin/docker:/usr/local/bin/docker

Note: Paste this code in the yaml file.

Execute yaml file

> sudo docker-compose up -d

Now you can access the browser with the ip of the instance with port 8080. It will show up like the page below.

What are some of the top business benefits of running Jenkins in a docker container? 

Businesses prefer Jenkins in a docker container when they want most of the configuration from the server under control. Most organizations keep Jenkins in the pipeline when they want the ability to run the server locally on any machine while experimenting with new features and configurations. 

Installing Jenkins with Docker composer will help businesses with:

  • Easy deployment and scalability 
  • Higher density with more workload running capacity 
  • Faster delivery of applications
  • Flexible management of environment

Wrapping up

In this article, we discovered how to configure a Jenkins controller with Docker compose. We asked you to set it up in volume so you can save the instance data between restarts. 

This is just the beginning of Docker Composer’s capabilities. You can finally encounter how the tool helps you administer CI/CD infrastructure. It’s time to get started with Docker compose today to extend the above mentioned benefits in your pipeline.
