What is the best way to split docker containers?

Question

Docker

The software on the node, in its work, launches a console utility in python. If you follow the recommendations, then you need to make 2 containers, but then the question is how to run from one and get its stdout. You can just make a bold image with a python and a node and everything will work. Another option is to fork the python and make http api to it, but I have never written on it and therefore I am not considering it yet.
What is the best way to do this?

Answer 1

While there are no load requirements - saw the image "all in one".
In general, such tasks are implemented through RPC, API, or message broker between applications.
