Installing and Setting up Jenkins through Docker

Jenkins is written in Java and is a scalable, highly efficient open source automation server which runs using various plugins designed for continuous integration, deployment and automation purposes. Any new language, framework or tool can be easily setup on Jenkins using these plugins. Jenkins is platform independent, easily configurable, customizable for any project we come up with and has a rich plugin ecosystem.

This post covers installation and setting up of Jenkins Server through Docker and talks about various features of dashboard.

Setting up Jenkins

The following steps will show how to setup a Jenkins host on your computer running Ubuntu OS.

  1. Open a terminal, run the docker command to make sure it’s running. If not, start it using the below command (1) and verify status (2) :
    1. sudo systemctl start docker
    2. sudo systemctl status docker
  2. Run the following command as shown in the screenshot below :Screenshot from 2018-10-06 23-55-41The above command pulls Jenkins image and runs Jenkins in the Docker container built from this image.

Visit http://localhost:8080 to enter the initial admin password which can be fetched from container logs, by identifying the ID.

Jenkins initial setup is required. An admin user has been created and a password generated.
Please use the following password to proceed to installation:


This may also be found at: /var/jenkins_home/secrets/initialAdminPassword


Enter this password in the browser prompt and we’re ready to customize Jenkins. Select Install Suggested Plugins and it will install the required ones. Once the plugin setup is complete you will be asked to create an Admin user. Fill in the details and click Save and Finish. Jenkins is now ready !

Jenkins Dashboard

When you first login to Jenkins you don’t have jobs or builds, on the top right corner there is an option to add short description. The bottom right corner has a REST API section, with some details on how to interact with Jenkins API.


On the left hand side of dashboard, Open Manage Jenkins and select Configure Global Security settings. By default, we should have security enabled and realm is Jenkins’ Own User Database. When more than one user is present in that case we should have Authorization set to different options, other than default.

Matrix-Based security –  It allows administrators to grant permissions to various groups depending upon the context. Here, I have selected this option and added new user account by granting various permissions, which can be seen below :Screenshot from 2018-10-07 00-39-20

So, we have identified important points on how to setup Jenkins server through Docker and have gained some insight on user management and access control.
