Direct Server Return Test

Summary

According to the Google Cloud documentation and the technical support team, creating a LoadBalancer kubernetes service will create a load balancer with direct server return, and therefore the incoming connection source IP address will be that of the originating client and not the load balancer. However that does not appear to be the case. This is a test kubernetes service + deployment that logs the incoming connection IP in order to validate whether Direct Server Return is working correctly.

Setup

Step 1: Create the service + deployment
