Story:

• As a Engineer, I would like to ensure the matrix of supported platform type is valid, so partners can quickly detect prior VCSP ticket that their result are valid or not
• As a Partner applying to VCSP, I want to know if my installation is valid by VCSP, so that I can resolve it prior applying a ticket to validation OCP on VCSP.

Goal:

• Create a Check/SLO checking if the platform type vs install method matrix is valid
• Supported platform type and install method:
  • openshift-install with platform type External
  • Assisted Installer with platform type None (User-managed networking mode)
  • Agent-Based Installer with platform type External
    • Is there a special config map for ABI which does not exists in AI?
• How to validate the install-method?: Check the following configuration

# cluster installed with openshift-install
$ omc get cm openshift-install-manifests -n openshift-config -o json | jq .data.invoker
"user" 

# cluster installed with assisted-installer
$ omc get cm openshift-install-manifests -n openshift-config -o json | jq .data.invoker
"assisted-installer"

# cluster installed with agent-based installer
$ oc  get cm openshift-install-manifests -n openshift-config -o json | jq .data.invoker
"agent-installer"
