Hi,

I'm trying to set up a Single Node OpenShift (SNO) cluster after making changes to the install-config.yaml file. Here's my current configuration:

yaml

apiVersion: v1
baseDomain: sno-master.com
metadata:
  name: sno-cluster       # Cluster name
networking:
  networkType: OVNKubernetes
compute:
  - name: worker
    replicas: 0
controlPlane:
  name: master
  replicas: 1
platform:
  none: {}
pullSecret:
sshKey:

When I run the openshift create cmd, I get the following error:

FATAL: Failed to fetch Cluster Infrastructure Variables
Error: Failed to generate asset "Cluster Infrastructure Variables" because "none" is a UPI platform.

I'm installing this on a preinstalled Red Hat Enterprise Linux Server VM. What should I specify in the platform section to proceed with the installation? Any guidance would be greatly appreciated!

Thanks

SNO on preinstalled RHEL does not sound correct. Are you sure you are looking for SNO? Perhaps you may be looking for OCP Local? Two different things. In the case of SNO, your base VM needs to be blank. However, it is best (easy) to use Assisted Installer for SNO, instead of using the openshift-install utility. At the very least, you would be better off starting with Assisted Installer first before moving on to the automated install via openshift-install utility. In the case of OpenShift Local. You will be using a different installer utility.

Thanks for the inputs, I have a bare metal server and downloaded the RHCOS ISO from the Red Hat console. Could you provide a detailed steps or any documentation/technote for installing SNO?

Hi Brett, thanks for the detailed explanation.

I booted the ISO file and started the installation, but at 59%, the system rebooted automatically, and I encountered this error.

Do you have any idea on this? It seems to be a mounting issue.

Thanks
