The error message indicates that you need to request a quota increase for your subscription. Quotas are enforced at various levels, such as resource groups, subscriptions, and accounts. For instance, your subscription might have a limit on the number of cores available in a specific region. If you try to deploy a resource with more cores than allowed, you'll receive an error stating that the quota has been exceeded. For full details on quotas, refer to: see Azure subscription and service limits, quotas, and constraints.
How to Request a Quota Increase:
1.Go to the Azure Portal and navigate to Subscriptions, then go to Usage + quotas. 2.Check for resource limits like vCPUs under Kubernetes Service in your selected region. Further, you can follow step-by-step instructions on how to request a quota increase here: Request a Quota Increase.
