Hi, Let me explain how it works now.
Each member object has kubernetes host IP (in which that member is created) and service proxy port. LB is working as previously where it distributes requests between members. Since member's IP and port is now kubernetes host IP and service proxy port, LB actually distributes requests to the kubernetes service proxies. I will attach LB log. You will see that LB is sending request to the kubernetes service proxies. I am accessing via cluster host name and proxy port ( http://myphp.apachestratos.org:8281/).
