Setup GitHub and Jenkins integration for code push

In this example, we're going to push changes to our GitHub repository and run build in Jenkins server.

How it works

1. User pushed local changes to GitHub.


2. GitHub tells Jenkins to run build.


3. Jenkins copies repository from GitHub under '/var/lib/jenkins/workspace/country' directory and runs build scripts if there are any.

Prerequisite

You must have git installed on your Jenkins server so run $ sudo apt-get install git before steps below.

Setup

1. Find GitHub web hook URL in Jenkins

• Select "Manage Jenkins" menu option on the left.


• Select "Configure System" option in the list.


• Click "Advanced" button under "GitHub" section.


• Tick "Specify another hook url for GitHub configuration" tickbox, note URL http://192.168.10.11:8080/github-webhook/ somewhere and untick it again.

2. Enable web hook URL in GitHub

• Select "Settings" tab.


• Select "Webhooks" menu option on the left.


• Click "Add Webhook" button.


• In the following screen, paste http://192.168.10.11:8080/github-webhook/ into "Payload URL" textbox.

3. Create a new project in Jenkins

• Select "New Item" menu option on the left.


• Name it as "country".


• Click "Free Style" project and save.


• Select "Git" in "Source Code Management" section.


• Paste HTTPS address of your repository into "Repository URL" textbox.


• Click "Add" button to add GitHub login credentials and click "Add" after adding your username(email address) & password information. Make sure it is selected in drop-down option in main screen.


• Leave "Branches to build" textbox blank to build on all branches.


• Under "Build Triggers" section tick "Build when a change is pushed to GitHub" tickbox.


• Click "Save" and exit.

Test

Commit a dummy file and push it to GitHub repository. If you check "country" project in your Jenkins GUI, you'll see a blue #1 icon in "Build History" which means the tests passed.
