VMware

Warning

Since OpenShift 4.3 it is not supported anymore to setup static IP address via Ignition configuration. You have to use the kernel boot args: Creating Red Hat Enterprise Linux CoreOS (RHCOS) machines

OVA do not support static ip's yet! - target 4.6 - BZ 1785122

Guestinfo property: guestinfo.afterburn.initrd.network-kargs

How you deploy OpenShift 4 VM's on VMware

iPXE, static ip addresses and govc

https://github.com/openshift-examples/ipxe

Kudos to my colleague Rodrigo Alvares

govc

Go CLI for vSphere/VMware - https://github.com/vmware/govmomi/releases

Create a VM Template via the OVA and copy via govc

Note

Use static DHCP via mac address

ovftool

Create VM direct from OVA:

Note

The example use static IP via ignition config - since OCP 4.3 not supported anymore!
