Setup GitHub Webhooks:

Add webhook to repo by browse repo on Github, go to Settings > Webhooks > Add webhook.

In the form Payload URL, insert the url below

http://115.79.141.254:23997/webhooks

I built a reverse proxy to redirect public ip to Jenkins container. So Jenkins can know when ever code are push.

Thank Long Nguyen for support me to forward port 23997.
