<p>I am following <a href="https://kubernetes.io/docs/tasks/administer-cluster/certificates/" rel="nofollow noreferrer">this guide and trying to create the TLS cert</a>, I am using <code>cfssl</code> and I am able to create the required file, but what should I provide for <code>MASTER_IP</code> and <code>MASTER_CLUSTER_IP</code>?</p>
<p>When I execute <code>kubectl cluster-info</code>, I can only see the following information:</p>
<pre><code>Kubernetes control plane is running at https://xxx.yy.zzz.40:6443
CoreDNS is running at https://xxx.yy.zzz.40:6443/api/v1/namespaces/kube-system/services/kube-dns:dns/proxy
</code></pre>
<p>Where can I find these two values?</p>

<p>Use below command</p>
<pre><code>kubectl get no -owide
</code></pre>
<p>The above command displays internal and external ips of all the nodes in the cluster</p>
