title: OKD 4.5 single node installation
body: <p>I'm trying to build an OKD 4.5 single node cluster following Craig Robinson blog post (at <a href="https://medium.com/swlh/guide-okd-4-5-single-node-cluster-832693cb752b" rel="nofollow noreferrer">https://medium.com/swlh/guide-okd-4-5-single-node-cluster-832693cb752b</a>). I faced with this issue first on bootstrap node, but after deleting and recreating the whole process again, it booted up successfully. But the same issue happened again while preparing control plane master node. After initial coreos download (which proves webserver is working fine), I get this recurring GET error message over and over again:</p>
  <pre><code>ignition[xxx]: GET error: Get &quot;https://api-int.lab.okd.local:22623/config/master&quot;: EOF
  </code></pre>
  <p>And this is my control plane node config:</p>
  <pre><code>ip=10.106.31.233::10.106.31.1:255.255.255.0:::none nameserver=10.106.31.231 coreos.inst.install_dev=/dev/sda coreos.inst.image_url=http://10.106.31.231:8080/okd4/ fcos.raw.xz coreos.inst.ignition_url=http://10.106.31.231:8080/okd4/master.ign
  </code></pre>
  <p>IPs are:
  okd-services: 10.106.31.231 ;
  bootstrap: 10.106.31.232 ;
  control-plane: 10.106.31.233</p>
  <p>I can reach the <a href="http://10.106.31.231:8080/okd4" rel="nofollow noreferrer">http://10.106.31.231:8080/okd4</a> address from remote pc and list the contents including master.ign file. Also pinging &quot;api-int.lab.okd.local&quot; is successful too. firewalld open ports on okd-services node are:</p>

  <p>I deleted and recreated the control plane to see if it solved the issue, but was not successful. Any idea what this issue means?</p>
