Cherrypy - Run function to clean up environmen on shutdown

Question

I am using Cherrypy framework for some simple REST based apps. IF the server is being closed down, either by the operator or by the OS, I want to be able to run a function to clean up the environmental setup for that session. In many cases you can do this on startup, by in this case there is hardware that I want to close down.

In the documentation I could not find anyway to catch a signal that the server is closing down and run some code

as mentioned by someone below, this can be easily done through a custom plugin. Write one and post if any help is needed. — Himanshu Jain, Dec 13 '18 at 22:11

I have just stumbled into a similar problem and this SO answer, together with the CherryPy docs on Plugins took me in the right direction: you should write a Plugin, very similar to the example in the docs, and then subscribe the Plugin registering it to the bus before starting the server engine.

Disclaimer: I'm pretty new to CherryPy, so my terminology might be inappropriate or even wrong.
