Vraquier

A poor-man "load-balancer" controller for kubernetes clusters without a cloud-controller. For when even kube-vip or metalLB are to much. It replicate the k3s behaviour by starting klipper-lb DaemonSet.

Requierements

kubelet should be started with --allowed-unsafe-sysctls 'net.ipv6.conf.all.forwarding,net.ipv4.ip_forward' --provider-id 'vraquier://<node name>' --cloud-provider=external

kind: Pod

  creationTimestamp: null
  name: vraquier
