This base variant needs resources you must create with your own values first:
  - minimum schedulable nodes 1
    use a target with at least 1 schedulable nodes before applying this base
Complete these prerequisites before applying the rendered objects.
Replace any <...> placeholders with values or files for your environment.
When the resources exist, re-run with:
