With the help of webhooks we can configure Jenkins to automatically trigger a build for every code push/change to our code repository.

Follow the below steps to trigger builds with webhooks:

1. Change Job Configuration in Jenkins

– In General section, select GitHub project and enter the url for your repository.

– In Source Code Management section, add your GitHub repository url.

– In Build Triggers section, select GitHub hook trigger for GITScm polling.

2. Add Webhook in your GitHub repository

– Goto GitHub Repository -> Settings -> Webhooks

– Click on Add Webhook button

– Enter Payload URL:

https://jenkinsUrl/github-webhook/

If you are running Jenkins on your localhost server then follow the steps mentioned here to generate a public URL.

– Select Content type as “application/x-www-form-urlencoded”

– Select SSL Verification (Enabled/Disabled)

– Under Which events would you like to trigger this webhook?, select “Send me everything”

– Click on Add Webhook button to save the settings.

3. Push any code change to your GitHub repository.

4. Jenkins will automatically trigger a build for the project.
