You should also look into adding <ahref="https://kubernetes.io/docs/concepts/configuration/assign-pod-node/#affinity-and-anti-affinity">inter-pod</a> affinity to prevent masters from running on the same node. However note that inter-pod affinity is costly and is not recommended in bigger clusters.</p><blockquote><p>NOTE: If the <ahref="#nodefeature-controller">NodeFeature controller</a> is enabled the replica count should be 1.</p></blockquote><p>If you have RBAC authorization enabled (as is the default e.g. with clusters initialized with kubeadm) you need to configure the appropriate ClusterRoles, ClusterRoleBindings and a ServiceAccount in order for NFD to create node labels. The provided template will configure these for you.</p></div></div><divclass="navigation-bottom d-flex flex-justify-between py-3"role="navigation"aria-label="footer navigation"><divclass="prev"><ahref="/node-feature-discovery/v0.13/usage/using-labels.html"class="btn"title="Using node labels"accesskey="p"rel="prev"><iclass="fa fa-arrow-circle-left"></i> Previous </a></div><divclass="next"><ahref="/node-feature-discovery/v0.13/usage/nfd-worker.html"class="btn"title="NFD-Worker"accesskey="n"rel="next"> Next <iclass="fa fa-arrow-circle-right"></i></a></div></div><hr><divclass="copyright text-center text-gray"role="contentinfo"><iclass="fa fa-copyright"></i><spanclass="time">2016-2023,</span><aclass="text-gray"href="https://github.com/kubernetes-sigs"rel="noreferrer"target="_blank">Kubernetes SIGs</a> Revision <aclass="text-gray"href="https://github.com/kubernetes-sigs/node-feature-discovery/commit/"title=""rel="noreferrer"target="_blank"></a><br><divclass="generator"> Built with <ahref="https://pages.github.com"rel="noreferrer"target="_blank"title="github-pages v227">GitHub Pages</a> using a <ahref="https://github.com/rundocs/jekyll-rtd-theme"rel="noreferrer"target="_blank"title="rundocs/jekyll-rtd-theme v2.0.10">theme</a> provided by <ahref="https://rundocs.io"rel="noreferrer"target="_blank">RunDocs</a>. </div></div></div></div><divclass="addons-wrap d-flex flex-column overflow-y-auto"><divclass="status d-flex flex-justify-between p-2"><divclass="title p-1"><iclass="fa fa-book"></i> Node Feature Discovery </div><divclass="branch p-1"><spanclass="name"> v0.13 </span><iclass="fa fa-caret-down"></i></div></div><divclass="addons d-flex flex-column height-full p-2 d-none"><dlid="versions"><dt>Versions</dt><scriptsrc="/node-feature-discovery/versions.js"></script><script>vardt=document.getElementById('versions');varitems=getVersionListItems();for(vari=0;i<items.length;i++){vardd=document.createElement('dd');vara=dd.appendChild(document.createElement('a'));a.appendChild(document.createTextNode(items[i].name));a.href=items[i].url;dt.appendChild(dd);}</script></dl><dl><dt>GitHub</dt><dd><ahref="https://github.com/kubernetes-sigs/node-feature-discovery"title="Stars: 621"><iclass="fa fa-github"></i> Home
