Embedded service load balancer in Klipper

Klipper Service Load Balancer

NOTE: this repository has been recently (2020-11-18) moved out of the github.com/rancher org to github.com/k3s-io supporting the acceptance of K3s as a CNCF sandbox project.

---

This is the runtime image for the integrated service load balancer in klipper. This works by using a host port for each service load balancer and setting up iptables to forward the request to the cluster IP. The regular k8s scheduler will find a free host port. If there are no free host ports, the service load balancer will stay in pending.
