How to trigger a flow during undeployment of a Mule application in CloudHub?

Question

I am working on a use case to trigger a specific flow that should trigger only when undeployment of the application happens from CloudHub.

I found an article that has script and am using the same to find out the flow start:

https://docs.mulesoft.com/scripting-module/2.0/scripting-module-examples

Can you help me to find out the way to trigger a flow after undeployment is initiated from CloudHub?

What are you doing at application startup with your script exactly? It is not clear if that method could be used at application undeployment without more information. — aled, Mar 08 '22 at 22:14
@aled At the application start am calling another service to make database entries. Now want to delete the entries at the time of undeployment. — ramsunka, Mar 08 '22 at 22:23

There is no way to do that. The script execution happens inside a flow execution, that is probably triggered by a scheduler at startup. There is no way to trigger a flow at shutdown of the Mule application. Note that it should be at shutdown, because undeployment is a CloudHub event that the Mule Runtime is not aware of. At undeployment CloudHub commands Mule to shutdown the application.
