In this exercise you will configure the build to execute automatically every time source code changes are committed 
to the repository in GitHub. This can be done using a webhook.  



Step 1:: Create a Webhook 

If you want to configure a webhook, use the following helper script.  The helper script will display all the values that you need to configure the webhook in GitHub. 

Run the helper script:

----
execute
getwebhook vote-app %cluster_subdomain%
----

 Important: Follow the instructions below and use the values displayed by the helper script.

----
 Log into https://github.com
 Navigate to your ``flask-vote-app`` repository
 Click on ``Settings`` and then on ``Webhooks``
 Click on the "``Add Webhook``" button and 
 fill in the form using the following information:
----

 Payload URL: *see the helper script output*
 Content type: application/json
 Secret: *see the helper script output*
 SSL verification: Disabled 

 *WARNING*:  If you see the error The URL you've entered is not valid, be very careful when copying and pasting the
long URL into the GitHub form as a space might be inserted at the line-break depending on which browser you are using!

Leave the other settings as they are.

----
click on the Add Webhook button
----

*WARNING*:  If you see the error The URL you've entered is not valid, check and remove any spaces in the
URL that you pasted.

GitHub will immediately test the webhook and show the result on the next page.  If you see a *tick* next to the webhook, that means it's working (note, you may need to refresh the page). 

You have now created a webhook

In this exercise you created a webhook so that every time you commit code to your repository in GitHub the build will be automatically triggered.
