<p>Kubernetes (v1.10.8) installed on my cloud by kismatic (v1.12.0). How I can update kubernetes to the latest version with <code>kubeadm</code>?</p>

<p>With such version difference - we currently have <a href="https://github.com/kubernetes/kubernetes/blob/master/CHANGELOG/CHANGELOG-1.23.md#v1231" rel="nofollow noreferrer">v1.23</a> (<a href="https://kubernetes.io/releases/" rel="nofollow noreferrer">see official supported releases</a>) - I would consider creating the cluster from the beginning.</p>
<p>If this is not possible, you should upgrade them step by step (from version to version). <a href="https://kubernetes.io/docs/tasks/administer-cluster/kubeadm/kubeadm-upgrade/" rel="nofollow noreferrer">Here</a> you can find guide that will help to upgrade kubeadm clusters.
A link to older versions you can find <a href="https://v1-19.docs.kubernetes.io/docs/tasks/administer-cluster/kubeadm/kubeadm-upgrade/" rel="nofollow noreferrer">here</a>, but</p>
<blockquote>
<p><em><strong>NOTE</strong></em>:
Kubernetes v1.19 documentation is no longer actively maintained. The version you are currently viewing is a static snapshot.</p>
</blockquote>
<p>However, you have to have in mind that upgrading through so many versions can cause other issues, so I recommend using the first option.</p>
