This is a Ruby application to configure your K8s cluster to work as a load-balancer, by utilizing the ingress and service/endpoint resources.
The common flow is to set up an ingress to talk to a ClusterIP service without a selector, and letting this application populate the endpoints list.
Install it yourself as:
$ gem install k8s_internal_lb
Run the application by specifying a configuration rb file, it can run in both one-shot mode as well as continuously.
$ k8s_internal_lb
Check the provided examples for ideas on how to configure the system.
