"ibmcloud pi system-pools" command is deprecated now. Use "ibmcloud pi datacenter" command.
Also RHCOS image versioning has changed. Instead of mapping to OCP versions, now RHCOS images are mapped to RHEL version. So, I made this change too in the script.

This looks good to me but IMO it needs some new doc added to point to where the OCP release version and rhcos versions can be found and how to make sure they're aligned.

  1. I am looking at the OCP, RHCOS and RHEL version mapping article link you provided in the comment. I can add this link to the Readme.md file between the sections "Windows 10 (64bit) and "Firewall Requirements" as follows.

OCP, RHCOS and RHEL Version Mappings
"For version mapping between these releases, please refer to https://access.redhat.com/articles/6907891"

  1. Looking at the article, I feel that the table column headings are not correct. The heading should be "OCP Versions" and "RHCOS/RHEL Versions"

  1. I would put this in the Usage or Advanced Usage section where the variables are being discussed, e.g. https://github.com/openshift/installer/blob/release-4.19/data/data/coreos/rhcos.json.
  2. Yes that is confusing but it's in line with how RH is talking about these two things. You can add some verbiage in your update to make sure it's clear which heading goes with which var

I have updated the script to point to 9-6 version for RHCOS and 4.20 version for OCP.

I have also updated the Readme file with the similar version changes, and also added the link that Christy mentioned in her review comments.
