libvirt-ocp4-provisioner - Provision an OCP 4.x.y cluster in minutes with Ansible, now with Single Node OCP support! .
Hi guys!I wanted to allotment with you a tool to provision a fully working OCP 4.x.y cluster in minutes using Ansible for automation, libvirt as virtualization provider and terraform as VMs templating and creation tool. https://github.com/kubealex/libvirt-ocp4-provisioner It will take care of all the infrastructure provisioning and OCP machines provisioning, starting and completing the UPI installation of a cluster. (IPI work in progress ;) ) To give a quick overview, this project will allow you to provision a fully working OCP stable environment, consisting of: * Bastion machine provisioned with: * dnsmasq (with SELinux module, compiled and activated) * dhcp based on dnsmasq * nginx (for ignition files and rhcos pxe-boot) * pxeboot * Loadbalancer machine provisioned with: * haproxy * OCP Bootstrap machine * OCP Master(s) VM(s) * OCP Worker(s) VM(s) From latest release, it also supports installing SNO on a single host! It also takes care of preparing the host machine with needed packages, configuring: * dedicated libvirt network (fully customizable) * dedicated libvirt storage pool (fully customizable) * terraform * libvirt-terraform-provider ( compiled and initialized basedon https://github.com/dmacvicar/terraform-provider-libvirt) PXE is automatic, based on MAC binding to different OCP nodes role, so no need of choosing it from the menus, this means you can just run the playbook, take a beer and have your fully running OCP 4.9.latest stable up and running. It has been tested on Fedora 3x and CentOS 7/8. Playing around with it and contributions to make it work even on different OSes is more than welcome, hope you enjoy it! Alex

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.

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/

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.
