Auto Trigger Jenkins Build /Jobs with github webhook

We're going to do github integration with jenkins using github webhook.

Steps:

1. You should have jenkins server hosted on public IP accessible remotely.

http://103.60.176.158:8080103.60.176.158

1. If you have localhost, you can also port your ip with any public IP. Ngrok is also a another option you can try.

2. To set webhook on the repo. Follow the path as given :

https://github.com/your_username/github_repo/settings/hooks/github.com

In my case, https://github.com/whoami-anoint/Hitop/settings/hooks/

While adding webhook:

• Payload URL : http://103.60.176.158:8080/github-webhook/

• Content type: application/json

• Secret : blank

• Which events would you like to trigger this webhook?

• Then make webhook active.

You may found some error. To avoid error from jenkins:

• Make sure the payload url should end with /. (To fix: 302 error)

• Content type be application/json . ( To fix : 502 error)

• Make sure you are getting 200 response.

Webhook is finally added on github repo.

1. Now, time to make pipeline on jenkins with the github repo:

• Add new item -> Pipeline

• Give any pipeline name. (Repo name is preferred to reference.)

• Source Code Management -> Repository URL and credentials (if private repo)

• Branches to build -> */main (your branch)

• Build Triggers -> ✅ GitHub hook trigger for GITScm polling

1. Make any changes on github repo.

1. Let's check on jenkins:

Also check on jenkins console:

• Started by GitHub push by whoami-anoint

🎉 We have successfully auto triggered the jenkins build using github webhook. Whenever, we made any changes on our github repo, that will be auto merge and auto build in jenkins.
