Deploy OpenShift 4.3 and later using static IP addresses for master and worker nodes. It will upload the OpenShift Bare Metal BIOS file and ignition files to a websever, and will create a bootable ISO for each node with static IP configuration and ignition parameters already set.
- DNS needs to be configured ahead of time
- Loadbalancers need to be configured ahead of time
- An existing webserver that can serve files to the OpenShift nodes for ignition.
