<p>I am trying to add a new Node pool in my existing Kubernetes cluster. One of the required field is <code>kubernetes version</code>. No versions show up in the dropdown and thus I can not Add a new node pool. Any idea on why this is the issue ?<a href="https://i.stack.imgur.com/aCkuj.png" rel="nofollow noreferrer"><img src="https://i.stack.imgur.com/aCkuj.png" alt="enter image description here" /></a></p>

<p>This could be a bug in the UI. As an alternative use the command <a href="https://learn.microsoft.com/en-us/cli/azure/ext/aks-preview/aks/nodepool?view=azure-cli-latest" rel="nofollow noreferrer"><code>az aks</code></a></p>
<pre><code>az aks nodepool add --cluster-name --name --resource-group --kubernetes-version --node-count
</code></pre>
<p>To know Kubernetes version use <code>az aks get-versions</code> command</p>
