One of the functions to link GitHub and Jenkins is called “Webhook”. By using this Webhook, you can run Jenkins’ jobs when pushing a branch to the repository managed on GitHub, when creating a new Pull Request, and so on.

There are three main ways to link Jenkins with GitHub and Webhook by the following three methods.

Jenkins Standard Webhook
– Set up “build for remote” provided as standard function of Jenkins
Git Plugin
– A plugin that can provide functions that can clone and execute git repositories when building Jenkins GitHub Plugin.
Plug-in to receive push event from GitHub
– Jenkins can automatically register Webhook to GitHub

Jenkins Standard Webhook
Build and trigger

Continue to configure Webhook with GitHub. From the repository page you can add it from Setting > Webhooks > Add Webhook.

Go to Github repository

Job
Job describes a series of operations that Jenkins wants to run. If you think that is something like batch files or Linux shell script now.

1. put name for Enter an item and press free style project build

2. Next page, chose build and set shell execution

3. write shell script

echo 'hello jenkins'

4. save task and run build

console output
