<p>When I execute the following commands (taken from the official installation guide for kubernetes), the output is unexpected (shown below: )
Command (On CentOS 7):</p>

<pre><code>cat &lt; /etc/yum.repos.d/kubernetes.repo
[kubernetes]
name=Kubernetes

exclude=kube*
EOF
setenforce 0
yum install -y kubelet kubeadm kubectl
systemctl enable kubelet &amp;&amp; systemctl start kubelet
</code></pre>

<p>Output:</p>

</code></pre>

<p>What you expected to happen:</p>

<p>kubeadm, kubeclt and kubelet get installed and are enabled</p>

<p>How to reproduce it:</p>

<p>Run the above mentioned commands on centos 7 (by following the guide at <a href="https://kubernetes.io/docs/setup/independent/install-kubeadm/" rel="nofollow noreferrer">https://kubernetes.io/docs/setup/independent/install-kubeadm/</a>)</p>

</code></pre>

<p>You seem to be missing <code>&lt;&lt;EOF</code> at the end of the first line.</p>

<p>Also, I can see there is a <strong>mistake</strong> in the <a href="https://kubernetes.io/docs/setup/independent/install-kubeadm/" rel="noreferrer">docs</a>.</p>

<p>Line containing <code>exclude=kube*</code> should be removed.</p>

<p>It should be as follows:</p>

<pre><code>cat &lt;&lt;EOF &gt; /etc/yum.repos.d/kubernetes.repo
