# Continuos Integration with GitHub and Jenkins

Everytime your developer makes changes to the code in Github Repository will you login to Jenkins and click "Build Now" all the time??

In previous section we have successfully created **Ansible playbook** and automatically deployed our application on **Tomcat** server but we have to click <img src="https://2593464885-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F3DMI85ymmo2BqduKTK9p%2Fuploads%2F7CQFhLNYIHsHaix5H0Wo%2Fimage.png?alt=media&amp;token=b5e67bb9-fb30-476d-8aa9-e2bd89008897" alt="" data-size="line"> everytime we wanted a build file.

What if I say we can automate that too! :relaxed: Let us do something so that if there is any change in the code **Jenkins** should detect it and Build new file, pass it to ANSIBLE, which will create our container and move the file in it & BOOM!!! our application is live.

1. Sign into your **GitHub** account and select your repository&#x20;
2. Go to settings option >> Choose ![](https://2593464885-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F3DMI85ymmo2BqduKTK9p%2Fuploads%2FQyAw823VfEoMDdAR3V7O%2Fimage.png?alt=media\&token=6c121d1e-06da-42a3-8762-0b52f3272561)>> click on Add Webhook (provide password, if asked)
3. You will be asked to enter **Payload** URL, you will get this from Jenkins.
   1. Login to Jenkins

      1. Manage Jenkins >> Configure system
      2. Search for "GitHub" <img src="https://2593464885-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2F3DMI85ymmo2BqduKTK9p%2Fuploads%2FKNpp7ZynQzLeBmFetl2W%2Fimage.png?alt=media&amp;token=259e1714-50ea-4279-aa97-6ca27dce7152" alt="" data-size="original"> >> Click on Advanced and tick the "specify another hook URL for GitHub Configuration" >> Copy the link and paste it in Github Payload URL section.

THAT'S ALL!! We have successfully implemented **Continuos Integration** Let's Try it out my making some changes in the code.&#x20;

I wil change the background color from green to blue and let's see if JENKINS can detect and build it or not!!
