How to get AKS cluster – Provisioning State: Scaling – back to live

Sometime during scaling operation on Azure Kubernetes Services, it hangs on  Provisioning State: Scaling.

Manually deleting VMs from the MC* group may have had some impact as well on this operation.

Solution: Upgrade the AKS cluster to the same Kubernetes version it is currently in (in this case, 1.13.5) from Azure CLI or CloudShell.

Step by step:

az aks upgrade –resource-group myResourceGroup –name myAKSCluster –kubernetes-version 1.13.10

Check status:

az aks show –resource-group myResourceGroup –name myAKSCluster –output table
