Installing RHCOS and starting the OpenShift Container Platform bootstrap process

To install OpenShift Container Platform on IBM zCX, you provision zCX for OpenShift appliance instances using zCX z/OSMF workflows and provide Red Hat Enterprise Linux CoreOS (RHCOS) initramfs, kernel, rootfs image, and the Ignition config file that was generated by the OpenShift Container Platform installation program for the IBM Z machine. If you have configured suitable networking, DNS, and load balancing infrastructure, the OpenShift Container Platform bootstrap process begins automatically after you have started the zCX for OpenShift appliance instances on z/OS.

For more information, see z/OS Management Facility workflows for zCX for OpenShift.
