Cluster Availability from outside the kubernetes

[lev-stas]

I am trying to build distributed cluster which is available from outside of kubernetes. But I don't understand how to do it. If I am creating custom load balancer service with external IP, it connects randomly to any cluster instance. But cluster announcement is realized based on pods internal ip, and I can't be redirected to another instance. If it is possible to announce cluster using service name, it would be much easier to redirect ingress to certain service.
Or maybe there is another way to make cluster available from external resources.
