when upgrading AKS node pool fails

 

If you upgrade fails, you get something like this. 


then just run the following command

az aks nodepool upgrade --cluster-name myclustername --resource-group resourcegroup --name mynodepoolname

Wait for it to complete, and you will have your clsuter

And sometimes i had to run it 5-6 times to get a upgrade completed - at times it last up to 12 hours
