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

I learned and got terraform to work with the KVM/Libvirt provider.

I saw Terraform with the dmacvicar/terraform-provider-libvirt provider, but sadly didn't get really warm with it. When some can explain to me how I can set up new images for every VM I would be very happy also there are more question in the pipeline. Sadly, the “Documentation” is not really that good. Maybe Terraform is also the wrong Application for me. I'm a little lost because I thought Terraform would be the big Solution I want and need, until now, not yet.

It looks like there was an issue dealing with "attaching an existing disk" to a terraform created VM. That's here: https://github.com/dmacvicar/terraform-provider-libvirt/issues/688

Nice. I’m straight KVM as it’s a mirror of work (my Lab) and I’m using the terraform-provider-libvirt provider. 20 minutes to fully build a site. Pretty cool.
