@den-rgb @gdbranco
After internal discussion it was deemed that listing the exact requirements within the TF docs and/or data source is not favored. It will be cumbersome to manage if any of these values get updated.
Instead it would be best if we link / provide URL to the official openshift document showing the requirements.
