  • Self hosted kubernetes
    Hey guys, I want to share a guide I’m pretty proud of which is talking about setting up kubernetes which leverages https://kubespray.io/#/ and https://metallb.universe.tf/ so you can host this yourself most people when spinning up kubernetes opt for k3s or get stuck with all the options or unable to setup the external ips for their services so these tools will eliminate the problem.

  • Trouble with RKE2 HA Setup: Part 2
    To avoid that, you can use a combination of haproxy and keepalived, an enterprise grade load balancer like the one from F5 or Citrix. Besides that you can also work with https://kube-vip.io or https://metallb.universe.tf. Source: 12 months ago
  • Kubernetes and feeling defeated
    Not sure if klipper is usable in a cluster with multiple nodes, as it binds to one port only. You may want to use MetalLB instead: https://metallb.universe.tf/. Source: about 1 year ago
  • Own kubernetes cluster
    What issue do you see with the load balancer? For self hosted clusters, one can use MetalLB for example to have such single outfacing IP which will failover to another node keeping the same IP if a node dies. Source: about 1 year ago
  • PaperLB: A Kubernetes Network Load Balancer Implementation
    Not to take anything away from OP but MetalLB also provides local load balancing. Source: about 1 year ago
