<p>what is wrong with my config,the kubernetes dashboard config is in 8443 port? and in the same namespace,why it give port not found exception?</p>

Dolphin
<p>The port 8443 is container port,could not access outside the container.You should using this command to find the cluster service port:</p>

<pre><code>kubectl get svc --namespace=kube-system

NAME                   TYPE        CLUSTER-IP      EXTERNAL-IP   PORT(S)                   AGE
kube-dns               ClusterIP   10.254.0.2      &lt;none&gt;        53/UDP,53/TCP,9153/TCP    131d
kubernetes-dashboard   NodePort    10.254.75.193   &lt;none&gt;        443:31085/TCP             131d
traefik                ClusterIP   10.254.169.66   &lt;none&gt;        80/TCP,443/TCP,8080/TCP   2d4h
</code></pre>

<p>the port 443 is the cluster port treafik could access. change container port 8443 to port 443.</p>
