<h1>Question</h1>

<p>What are the commands to start/stop the K8S cluster? After installation is done following <a href="https://kubernetes.io/docs/setup/independent/create-cluster-kubeadm/#24-initializing-your-master" rel="nofollow noreferrer">Using kubeadm to Create a Cluster</a>, restarted the CentOS server and the K8S cluster is not running after restart. </p>

<p>There are services mentioned in <a href="https://kubernetes.io/docs/getting-started-guides/fedora/fedora_manual_config/" rel="nofollow noreferrer">Fedora (Single Node)</a> listing services but there are no such services installed via kubeadm.</p>

<pre><code>Failed to restart etcd.service: Unit not found.
Failed to restart kube-apiserver.service: Unit not found.
Failed to restart kube-controller-manager.service: Unit not found.
</code></pre>

<h2>Environment</h2>

<p>CentOS 7 on Virtual Box. K8S 1.8.5</p>

<pre><code>$ kubectl get nodes
NAME      STATUS    ROLES     AGE       VERSION
master    Ready     master    36m       v1.8.5
node01    Ready     &lt;none&gt;    35m       v1.8.5
node02    Ready     &lt;none&gt;    35m       v1.8.5
</code></pre>

<p>As you are using <strong>kubeadm</strong> to initiate and administrate the k8s cluster.As I understand kubeadm use following approach</p>

<p>Systemd manage only kubelet service on the node.</p>

<p>Kubelet create and manage k8s control plane componenets (kube-api server, kube-controller-manager , etcd and scheduler, kube-proxy) as a <strong>static pod</strong>.    </p>

<p>Kubelet access their json manifest files from <code>/etc/kubernetes/manifests</code>. </p>

<p>So if you want to remove control plane components you just need to move these manifest files in another directory.    </p>
