<p>I am trying to create cluster by using <a href="https://gridscale.io/en/community/tutorials/kubernetes-cluster-with-kubeadm/" rel="nofollow noreferrer">this article</a> in my WSl Ubuntu. But It returns some errors.</p>
<p>Errors:</p>
<pre><code>yusuf@DESKTOP-QK5VI8R:~/aws/kubs2$ sudo systemctl daemon-reload

yusuf@DESKTOP-QK5VI8R:~/aws/kubs2$ sudo systemctl restart kubelet

</code></pre>
<p>I don't understand the reason when I use <code>sudo systemctl restart kubelet</code>. Error like this occurs:</p>
<pre><code>docker service is not enabled, please run 'systemctl enable docker.service'
</code></pre>
<p>When I use:</p>
<pre><code>yusuf@DESKTOP-QK5VI8R:~/aws/kubs2$ systemctl enable docker.service
Failed to enable unit, unit docker.service does not exist.
</code></pre>
<p>But I have docker images still runnig:</p>

<p>What is wrong while creating Cluster Kubernetes in WSL? Is there any good tutorial for creating cluster in WSL?</p>

<p>Tutorial you're following is designed for cloud Virtual machines with Linux OS on them (this is important since WSL works a bit differently).
E.g. SystemD is not presented in WSL, behaviour you're facing is currently <a href="https://github.com/MicrosoftDocs/WSL/issues/457" rel="nofollow noreferrer">in development phase</a>.</p>
<p>What you need is to follow designated tutorial for WSL (WSL2 in this case). Also see that docker is set up on Windows machine and shares its features with WSL integration. Please find <a href="https://kubernetes.io/blog/2020/05/21/wsl-docker-kubernetes-on-the-windows-desktop/" rel="nofollow noreferrer">Kubernetes on Windows desktop tutorial</a> (this uses KinD or minikube which is enough for development and testing)</p>
<p>Also there's a <a href="https://kubernetes.io/blog/2020/05/21/wsl-docker-kubernetes-on-the-windows-desktop/#minikube-enabling-systemd" rel="nofollow noreferrer">part for enabling SystemD</a> which can potentially resolve your issue on a state where you are (I didn't test this as I don't have a windows machine).</p>
