<p>I've installed Kubernetes with docker-for-desktop.
Now I want to create a user (following RBAC principle). I'm using private certificates and want to sigh them against the <code>ca.crt</code> of the cluster.</p>

<p>For minikube this <code>ca.crt</code> was in <code>.minikube/ca.crt</code>but I can't find it in the installation with docker?</p>

<p>By default, your HyperKit VM doesn't mount volumes locally in docker-for-desktop.</p>

<p>Your best bet is to copy the ca.crt manually to your machine using <code>kubectl cp</code>.</p>

<p>Example:</p>

<pre><code>kubectl cp kube-apiserver-docker-desktop:run/config/pki/ca.crt -n kube-system /tmp/ca.crt
</code></pre>
