Describe the bug
The setup of AKS-Edge for Azure IoT Operations is setting up a machine with to little CPU Cores (and probably also RAM/Disk space).
The documentation on Prepare your Azure Arc-enabled Kubernetes cluster says it needs 8 CPU Cores, 16 GB of RAM and 52-GB free disk space.
The provided setup script of this repository however creates a machine with less than the required resources:
I can confirm that the CPU requirements are too low. When I tried to update a deployment, the pod didn't start because of insufficient cpu.
A describe on the pod showed this warning in the event-list:
Events:
Type Reason Age From Message
---- ------ ---- ---- -------

The AIO documentation has been updated, and you can find minimum and recommended specs here. Please let us know if you find any other discrepancies. Thank you for the feedback!
