Hello, I'd like to run two different containers, each with a different executable, on the same specific external IP address in Google Container Engine (GKE). One executable is a web server and the other is a web client. Requests from the client should originate from the same IP that the server listens on.
So far I've been able to get the client executable to run on an external IP address that I had reserved via Networking > External IP addresses in the cloud console [1]. The address is assigned to my only VM instance, so IIUC all containers running there use this address for their outgoing IP traffic. I can confirm the external IP address eg. by attaching to a running container [2] and fetching checkip.dyndns.org from there [3]. OTOH, I haven't been able to expose the server executable on the same IP address. I tried both .yaml service configuration and kubectl expose but can't get either to work. What should be the value of my service's spec.type? If I set type = LoadBalancer and LoadBalancerIP = <my external IP above>, load balancer creation fails because the IP is reported as already used. If I set type = NodePort, the service gets created, but requests to <my external IP>:8080 aren't forwarded to the server executable (configured to listen on port 8080). I'd appreciate any help.
