When attempting to create an AKS resource using default node pool settings settings for AKS free tier, I get the following error:
{"code":"InvalidTemplateDeployment","details":[{"code":"ErrCode_InsufficientVCPUQuota","message":"Preflight validation check for resource(s) for container service $myServiceNameHere in resource group $myResourceGroupHere failed. Message: Insufficient regional vcpu quota left for location westus2. left regional vcpu quota 0, requested quota 824905271464. Details: "}],"message":"The template deployment 'microsoft.aks-1725638389281' is not valid according to the validation procedure. The tracking id is 'fb3c2e9e-cd7a-4543-92f1-4710dda4261e'. See inner errors for details."}
The subscription and account I'm using is newly created and has >$195 in azure credits, and I have not configured any limits. I cannot find this ErrCode_InsufficientVCPUQuota listed anywhere online or any guides towards remediating the issue, and I have no clue where this "824905271464" number is coming from.
What is the issue preventing me from creating a resource at this time?
Thanks for posting your question in the Microsoft Q&A forum.
Azure enforces default quota limits on resources like vCPUs for each subscription and region. This is to prevent accidental over-provisioning and to manage capacity. In your case, the error indicates that you've reached the vCPU quota limit for the West US 2 region.
To resolve this issue, you have a few options:

Hi - I have now attempted creating the resource in EastUS2, westcentralus, and centralUS, all of which have failed with the same error message. Another two error messages from doing so:
EastUS2:

CentralUs:

I am unable to use lower vCPU counts - the interface tells me when selecting B nodes that "basic nodes cannot be scheduled", so I am using the absolute lowest cost D family machines with the absolute lowest vCPU count that azure appears to support, 2. I have no other resources in any other environments consuming vCPUs. Is the underlying issue here that I am attempting to create these resources on a newer non-pay-as-you-go account, or is it something else?

Hi Taylor H,
It appears that the issue you're facing is related to the vCPU quota limits on your current subscription type, as you’ve tried multiple regions without success. Even though you're using low vCPU counts, the default quotas for certain subscription types, like Free Trial or non-pay-as-you-go accounts, are typically very limited across all regions.
Steps to resolve:
If you are on a Free Trial or CSP subscription, these plans often come with lower default vCPU quotas, which may explain why you're hitting the quota limit even with minimal node sizes.
Upgrading to a Pay-As-You-Go subscription would give you higher default vCPU quotas in each region.
Go to Azure Portal > Subscriptions > Usage + quotas, and request an increase in the vCPU quota for the regions you're targeting (e.g., eastus2, centralus).
Here’s how to request a vCPU quota increase.
Thank you.
