Is it possible to manage the main program with several other programs?

Question

Virtualization

Hello, I want to immediately apologize for the probably incorrect or inaccurate wording of the question.
I am supposed to write a program that works with containers on Windows to implement my task. Only the same third-party program with which I will have to work will be placed in each of the containers. For example, let's take 3 containers in each of which this program has all identical functions, libraries, etc.
From a performance point of view, running this program in each container is not profitable. Is there such an option that one program will be launched for three containers, which they will control in turn, transferring their memory to it, so to speak? (The programs are identical, but the personal data for using it will all be different, because of which the program should not know that copies of it are currently working).
Perhaps you know, or have an idea how to implement this better, I would love to read your answers.

Answer 1

Certainly. Write a dockerfile, make three phased builds, passing memory and files along the chain.
