I am trying to run 2 containers on Google Kubernetes Engine, both running ZeroMQ using the PUB/SUB model to relay messages from one container to the other. I am developing on Visual Studio Code and using the Cloud Code plugin to deploy the containers to my remote cluster using scaffold.

The GKE cluster consists of 3 nodes running e2-small instances

When I deploy the containers they get seem to get deployed correctly, however in the output section I never see any of the logs showing that the messages are getting sent correctly as the code suggests they should.

Please find the code here : https://github.com/alhennessey92/zeromq-kubernetes-test I think it is relevant to this issue as well as the final output logs from the terminal.

Final logs from terminal

I am not sure why this does not seem to be working as it should, I should be seeing the printed logs displaying from both the pub and sub containers, but am not.
