Hi, I’m building a container cluster using CoreOs and Kubernetes, and I’ve seend that in order to expose a Pod to the world you have to create a Service with Type: LoadBalancer. I was wondering how to achieve this with Floating IP. I can’t seem to find any documentation about it.

So… the service is there when k8s wants to support it.

I have 3 master with etcd configured. Is there any basic template to use for confd to update haproxy dynamically with server and pod ports?

You have two options here :

  1. Make your IP static and hardcode that in Service configuration file
  2. Make an Ingress controller and define your internal service in ingress, this way your ingress will redirect your traffic to your internal service

It seems like there’s no way to directly do it in the kubernetes side. Anyway, I guess you could accomplish it in the cloud provider side.
For example, for Openstack, you can associate a floating IP to the VIP of the created Load balancer of the service.
