Question

AKS add windows node pool

Dondapati, Navin 291

Hi Guys,

We are trying windows pool on AKS using below power shell but it fails:

aks nodepool add --resource-group rg1--cluster-name aks01--os-type Windows --name npwcd --node-vm-size Standard_D4s_v3 --kubernetes-version 1.25.6 --aks-custom-headers WindowsContainerRuntime=containerd --node-count 1 --network-plugin azure --windows-admin-username azure --windows-admin-password 'Password'

unrecognized arguments: --windows-admin-username azure --windows-admin-password Password

tried below

az aks nodepool add --resource-group rg1 --cluster-name aksdev001 --os-type Windows --os-sku Windows2019 --name npwin --node-count 1

(WindowsProfileMissing) Windows profile definition is missing for the cluster.

Code: WindowsProfileMissing

Message: Windows profile definition is missing for the cluster.

We tried below it works, but why cant we use az aks nodepool add?

az aks create --resource-group rg1 --name aks-byo-cni-win --node-count 1 --nodepool-name systemnp --node-vm-size Standard_DS2_v2 --node-resource-group rg-aks-byo-cni-nodes --generate-ssh-keys --network-plugin none --enable-cluster-autoscaler --min-count 1 --max-count 10 --zones 1 2 3 --windows-admin-username azureuser --windows-admin-password "Script@12345678"

Regards,

Navin

There is no option for adding windows admin username & password while creating the new nodepool . Those credentials needs to be added at the time of AKS cluster creation.

From the below document , the command az aks nodepool add - you don't see any flag for --windows-admin-username & --windows-admin-password.

https://learn.microsoft.com/en-us/cli/azure/aks/nodepool?view=azure-cli-latest#az-aks-nodepool-add

Those are available only at the time of AKS cluster creation (see the command az aks create in below official document)

https://learn.microsoft.com/en-us/cli/azure/aks?view=azure-cli-latest#az-aks-create

////////////////

While creating the AKS cluster , if you have not added the windows-admin-username - there will be a default user name called : azureuser (You can get those details from az aks show -g resourcegroupname -n aksclustername)

You can use the new password by going to Azure Portal windows VMSS nodes -> Reset Password.

Hope that explanation helps ! Kindly Let us know if you have any additional questions !!

Shiva.
