<p>I have a Intel Atom Dual Core with 4 GB RAM left over and want to use it to run docker images. 
What possible solutions are there for such a local installation? I already found MicroK8s which looks promising, yet wondering which other alternatives there are. Is there maybe a complete distribution focused on only running docker containers? </p>

<p>If I would install MicroK8s, I still have to also manage the Ubuntu installation hosting it. Would be nice to have a distribution that only focuses on running docker containers and updates operating system and docker stuff together, so I know it always works fine together.</p>

<ul>
<li>If you can run Docker, run <a href="https://www.docker.com/products/kubernetes" rel="nofollow noreferrer">Docker's Desktop Kubernetes Cluster</a>.</li>
<li>You also can run <a href="https://minikube.sigs.k8s.io/" rel="nofollow noreferrer"><code>minikube</code></a> (on a top of docker, or hypervisor, or virtualbox)</li>
<li><code>kind</code> - <a href="https://kind.sigs.k8s.io/" rel="nofollow noreferrer">which is docker in docker k8s cluster.</a></li>
</ul>
