title: First try on a etcd HA & k3s cluster
body: <p>I tried to run my first cluster as I'm currently trying to learn so I can work in Cloud Engineering hopefully.</p>
  <p>What I did :</p>
  <p>I have 3 Cloud Servers ( Ubuntu 20.04), all in one Network,</p>
  <p>I've successfully set up my ETCD Cluster ( cluster-health shows me all 3 Network IPs of the Servers, 1 leader 2 not leader)</p>
  <p>now I've installed k3s on my first Server</p>
  <pre><code>curl -sfL https://get.k3s.io | sh -s - server \ --datastore-endpoint=&quot;https://15.0.0.2:2380,https://15.0.0.4:2380,https://15.0.0.3:2380&quot; 
  </code></pre>
  <p>I've done the same on the 2 other Servers the only difference is I added the token value to it and checked it beforehand in:</p>
  <pre><code> cat /var/lib/rancher/k3s/server/token 
  </code></pre>
  <p>now everything seems to have worked but when I tried to <code>kubectl get nodes</code> , it just shows me one node...</p>
  <p>does anyone have any tips or answers for me?</p>
