javascript - How to communicate with an external exe program from an google cloud app engine?

Question

I want to make a Lichess BOT that plays chess using Stockfish engine. Stockfish has an .exe file I can run and communicate through UCI protocol. I want to write my application in node.js and deploy on google cloud app engine. I can deploy a node.js program, but how do I get stockfish.exe program to run on app engine and use it in my javascript code?

Answer 1

This is not possible in App Engine Standard.

The reason for that is that the environments in App Engine are controlled by Google so that performance/scability and security issues are minimized. And enabling executables to be executed in such environment could pose a high security risk.

For the Flexible environment you have a bit more flexibility with the use of Docker Files, and this community answer might be helpful on that regard, however, I would say that this is still not recommended.
