This guide will go over installing the git plugin for Jenkins. Jenkins already installed and running (Very basic setup).
Install git via apt-git
First git needs to be installed on the Ubuntu machine
> sudo apt-get install git
Install plug in
Open your Jenkins install in a web browser. Mine happens to be located at http://192.168.0.7:8080/
After you login click on Manage Jenkins
Click on Manage Plugins
Click on the Available Tab
In the filter enter "git plugin"
Then select "Git Plugin" and finally click on "Install without restart"
Plug-in installation starts
After the plug-in is successfully installed click on "Go back to the top page"
Create the ssh keys in the Jenkins home directory. In my set up the Jenkins home directory is at /var/lib/jenkins
Switch over to the Jenkins user and create its ssh keys
> sudo su jenkins
> ssh-keygen -t rsa -b 2048
Copy the .ssh/id_rsa.pub key to your git remote repository
Setting up a remote git repository in a job
Click on New Job
Name it Test
Select "Build a free-style software project"
Select "Git" then enter your remote repository connection url.
For example sshLfirstname.lastname@example.org/my_git_project.git
Click Build now
The Build was successful
This is a very simple deploy, all it does is download from the git remote repository.
