Limit exceeded for cluster creation on Azure Kubernetes, where to cleanup?

I have deleted the old clusters by deleting the resource group completely. But when I try to create a new cluster, I am getting error as limit exceeded.

As you can see in the below error.

{"code":"InvalidTemplateDeployment","message":"The template deployment 'microsoft.aks-20210803135741' is not valid according to the validation procedure. The tracking id is '979df053-50fa-4201-9643-5f3029e0b43d'. See inner errors for details.","details":[{"code":"QuotaExceeded","message":"Provisioning of resource(s) for container service testingdelete in resource group testingdelete failed.

How to cleanup the old details which are left?

Solution 1:

If you have deleted the resource group, and it has completed OK then this should not be using your core quota. If there is nothing else in your sub using the core quota then you would need to raise a support ticket to get that resolved.

However, the easiest solution is just to raise the quota. You can do this by raising a "Service and Subscriptions Limits" support requests (it is free) and indicating what quota you need increasing. Generally this is completed within a few minutes.
