27There is a bunch of ways to provision Kubernetes, but you need to take few elements into
28account:
29</p>
30<ul class="org-ul">
31<li>is it a “throwable” cluster, for development or tests purposes</li>
32<li>is it a local cluster (not exposed to the public)</li>
33<li>is it a production grade cluster (exposed to the public)</li>
34</ul>
35
36<p>
37For the <i>throwable</i> case, there is a bunch of possibilities, from running VMs to running
38kubernetes in containers.
39</p>
40
41<ul class="org-ul">
42<li><a href="https://github.com/saschagrunert/kubernix">kubernix</a> for <a href="nixos.html">NixOS</a> specific.</li>
43<li><a href="kubernetes/minikube.html">minikube</a></li>
44<li><a href="kubernetes/kind.html">kind</a></li>
45<li>microk8s</li>
46</ul>
47
48<p>
49For the local cluster part, you can rely on <a href="https://github.com/kelseyhightower/kubernetes-the-hard-way/"><i>the hard way</i></a> or on tools from the community,
50depending on your system.
51</p>
52
53<ul class="org-ul">
54<li>I am trying to use <a href="nixos.html">NixOS</a> for this : <a href="kubernetes/kubernetes_on_nixos.html">Kubernetes on NixOS</a>.</li>
55<li>In parallel, I’m gonna setup k8s using <a href="microk8s.html">microk8s</a> on VMs too, so that I can test with a
56Ubuntu host.</li>
57</ul>
58
59<p>
60For the production grade cluster, <i>well</i>, I am not there yet, but best advice, use GKE or
61<a href="openshift.html">OpenShift</a>.
