title: EKS - How to annotate some nodes in USERDATA?
body: <p>To prevent <code>Cluster Auto Scaler</code> from terminating some of nodes, I would need to <strong>annotate</strong> them with:</p>
  
  <pre><code>cluster-autoscaler.kubernetes.io/scale-down-disabled=true;
  </code></pre>
  
  <p>Is there a way to do so in <code>USERDATA</code> script?
  For labeling the nodes, there is no issue, and it is possible to do so via:</p>
  
  <pre><code>    --kubelet-extra-args \
          "--node-labels=
  </code></pre>
  
  <p>Thanks</p>
