While creating the AKS getting following error

Hi Varma,

Welcome to MS Q&A

By ensuring that your AKS cluster configuration includes a system node pool, you should be able to resolve the error and successfully create the clusterThe error message "Creating an Azure Kubernetes Service cluster without a system node pool is not permitted" indicates that the AKS cluster creation process requires at least one system node pool to be defined. Here are the steps to resolve this issue:

1. Define a System Node Pool: Ensure that your AKS cluster configuration includes at least one system node pool. A system node pool is required to run critical system pods and services.
2. Use Azure CLI to Create AKS Cluster with System Node Pool:

   az aks create \
     --resource-group myResourceGroup \
     --name myAKSCluster \
     --node-count 1 \
     --node-vm-size Standard_DS2_v2 \
     --enable-addons monitoring \
     --generate-ssh-keys
   

1. Check Your Configuration: Verify that your configuration file or parameters include a system node pool. Here is an example of how to define a system node pool in your configuration:

1. Review Documentation: Refer to the official Azure documentation for more details on creating AKS clusters and configuring node pools:

• Create an AKS cluster using the Azure CLI
  • Node pool concepts in Azure Kubernetes Service (AKS)

By ensuring that your AKS cluster configuration includes a system node pool, you should be able to resolve the error and successfully create the cluste, so size you can keep

Standard_DS2_v2

Please let me know if any further question

kindly accept if it helps

Thanks
