<p>during the AKS cluster creation/configuration I do not see option to specify if we will be using the Linux or Windows containers and according to that to choose OS system which will be installed on the Nodes for containers? How is this being configured/selected?</p>
<p>Thanks</p>

<p>From the <a href="https://learn.microsoft.com/en-us/azure/aks/windows-faq#can-i-run-windows-only-clusters-in-aks" rel="nofollow noreferrer">docs</a>:</p>
<blockquote>
<p>All AKS clusters are created with a default first node pool, which is
Linux-based. This node pool contains system services, which are needed
for the cluster to function. It's recommended to run at least two
nodes in the first node pool to ensure reliability of your cluster and
the ability to do cluster operations. The first Linux-based node pool
can't be deleted unless the AKS cluster itself is deleted.</p>
</blockquote>
<p>With that been said.. you must have at least 1 node group which is Linux based.</p>
