<p>I deployed K8S cluster on AWS EKS (nodegroup) with 3 nodes. I'd like to see the pod CIDR for each node but this command returns empty: <code>$ kubectl get nodes -o jsonpath='{.items[*].spec.podCIDR}'</code>. Why doesn't it have CIDR in the configuration?</p>
<pre><code>$ kubectl get nodes

<p>From kubelet let documentation I can see that it is only being used for standalone configuration
