I am trying to build a service that needs to be connected to a socket over the internet without downtime. The service will be reading and publishing info to a message queue, messages should be published only once and in the order received.

For this reason I thought of deploying it into Kubernetes where I can automatically have multiple replicas in case one process fails, i.e. just one process (pod) should be running all time, not multiple pods publishing the same messages to the queue.

These requests need to be routed through a proxy with a static IP, otherwise I cannot connect to the socket. I understand this may not be a standard use case as a reverse proxy as it is normally use with load balancers such as Nginx.

How is it possible to build this kind of forward proxy in Kubernetes?

I will be deploying this on Google Container Engine.
