Is there some software/framework/workaround that provide an easy way to exchange messages between the host and a container?
More specifically, I have a host running a Python server on Ubuntu. This host creates several containers running Node servers on an Ubuntu image. The host should send and receive messages to/from each container and they must not use the internet for this.
If there's no such software/framework, one possible workaround would be to write the messages to a file inside the container and the host reads them? Would it be possible to run several threads doing the same at the same time (each thread on a specific container)?
