I am developing a website that runs a simulation given a user-submitted script. I tried to follow some Online Judge architectures, but in my case, I need to send user input and receive the output in realtime, like a simulation.

I tried Kubernetes Jobs, but isn't seems so easy to communicate with the container, especially if I need a Kubernetes client on the language that I am working.

So, my question is: Given this scenario, what is the best approach to orchestrate multiple containers with interactive I/O programmatically?

*Obs.: I am not worrying about security yet.
