<p>I am a newbie and are learning kubernetes，when i try to build kubernetes cluster, i meet some questions.
here's my questions, i don't know how to resolved it</p>

<p>When I enter the command：</p>

<pre><code>sudo kubeadm init --pod-network-cidr=10.244.0.0/16 
</code></pre>

<p>I have encountered these problems：</p>

<p><a href="https://i.stack.imgur.com/evtYv.png" rel="nofollow noreferrer">enter image description here</a></p>

<p>i tried to specified --apiserver-advertise-address=$(hostname - i), i meet another question:</p>

Unfortunately, an error has occurred:
    timed out waiting for the condition

This error is likely caused by:
    - The kubelet is not running
    - The kubelet is unhealthy due to a misconfiguration of the node in some way (required cgroups disabled)

If you are on a systemd-powered system, you can try to troubleshoot the error with the following commands:
    - 'systemctl status kubelet'
    - 'journalctl -xeu kubelet'

Additionally, a control plane component may have crashed or exited when started by the container runtime.
To troubleshoot, list all containers using your preferred container runtimes CLI, e.g. docker.
Here is one example how you may list all Kubernetes containers running in docker:
    - 'docker ps -a | grep kube | grep -v pause'
    Once you have found the failing container, you can inspect its logs with:
    - 'docker logs CONTAINERID'

<p>I look forward to someone who can help me answer!</p>

<p>Did you have any cluster running prior to this? If so, you have to clean up old configs and re-bootstrap your cluster. </p>

<ol>
<li>Reset current cluster- <code>kubeadm reset -f</code></li>
<li>Delete obsolete config (entire directory) - <code>sudo rm -rf /etc/kubernetes/</code></li>
<li>Pull images once again - <code>kubeadm config images pull</code></li>
<li>Pass bridged IPv4 traffic to iptables chains. This is a requirement for some CNI plugins to work
<code>sysctl net.bridge.bridge-nf-call-iptables=1</code></li>
<li>Init the cluster - <code>kubeadm init --pod-network-cidr=10.244.0.0/16</code> </li>
</ol>
