Jenkins Git Integration on Ubuntu

In this article, we will install Jenkins on Ubuntu and examine the following items:

• Developer commits to source code management system.
• Jenkins job will be notified.
• Jenkins send a pull request to GitHub.

Configuration of Jenkins on Ubuntu

First, we have to add the key and source list to apt. Apply, below two commands in order.

wget -q -O - http://pkg.jenkins-ci.org/debian/jenkins-ci.org.key | apt-key add -

echo deb http://pkg.jenkins-ci.org/debian binary/ > /etc/apt/sources.list.d/jenkins.list

Now we need to update Ubuntu.

apt-get update

We need to install Jenkins now. Be aware it takes some time to install Jenkins.

apt-get install jenkins

The default port number for Jenkins is 8080. The below screenshot is the entry page or Dashboard of Jenkins.

Restart Jenkins with this command: http://localhost:8080/restart

We need git in our system so we will install it with the below command.

sudo apt-get install git

Congratulations, Jenkins’s environment setup has been completed. :)

Integrate Jenkins and GitHub

In this tutorial, we will use GitHub as a source code repository. We need to install the Jenkins GitHub plugin, for more information visit https://wiki.jenkins-ci.org/display/JENKINS/GitHub+Plugin .

Manage Jenkins page, select Manage Plugins on the available tab search box  = GitHub

The above figure shows that GitHub API Plugin has successfully installed to the system.

We will configure Jenkins to trigger a build when a file is modified in the GitHub repository.

• Connect to the Jenkins server again. Click the New Item link in the left navigation.
• Name your build job, and choose the Freestyle project. Click OK.

• Copy the URL from your GitHub project.

• In order to manage Jenkins, we need to set executable.

• Create a new job and name it.

• Specify your GitHub project at source code management.

• Add credentials  Username / Password

• You can change the build trigger using the below options.

• If your job is triggered you should below result. It will finish with SUCCESS! :)

Thanks.
