title: Config not found: /etc/kubernetes/admin.conf -- After setting up kubeadm worker node
body: <p>Following <a href="https://upcloud.com/community/tutorials/install-kubernetes-cluster-centos-8" rel="noreferrer">this tutorial</a>, I set up a worker node for my cluster. However, after running the <code>join</code> command and attempting <code>kubectl get node</code> to verify the node was connected, I am met with the following error</p>
  <pre><code>W0215 17:58:44.648813 3084402 loader.go:223] Config not found: /etc/kubernetes/admin.conf
  The connection to the server localhost:8080 was refused - did you specify the right host or port?
  </code></pre>
  <p>Checking for the existence of <code>admin.conf</code> in <code>/etc/kubernetes/</code> shows it does not exist. I have ensured that <code>$HOME/.kube/config</code> is also clear. Why is the join command not creating an admin.conf file?</p>
