It detects hardware features available on each node in a Kubernetes cluster, and advertises those features using node labels and optionally node extended resources, annotations and node taints. Node Feature Discovery is compatible with any recent version of Kubernetes (v1.21+).</p> <p>NFD consists of four software components:</p> <ol> <li>nfd-master</li> <li>nfd-worker</li> <li>nfd-topology-updater</li> <li>nfd-gc</li> </ol> <h2 id="nfd-master">NFD-Master</h2> <p>NFD-Master is the daemon responsible for communication towards the Kubernetes API. That is, it receives labeling requests from the worker and modifies node objects accordingly.</p> <h2 id="nfd-worker">NFD-Worker</h2> <p>NFD-Worker is a daemon responsible for feature detection. It then communicates the information to nfd-master which does the actual node labeling. One instance of nfd-worker is supposed to be running on each node of the cluster,</p> <h2 id="nfd-topology-updater">NFD-Topology-Updater</h2> <p>NFD-Topology-Updater is a daemon responsible for examining allocated resources on a worker node to account for resources available to be allocated to new pod on a per-zone basis (where a zone can be a NUMA node). It then creates or updates a <a href="/node-feature-discovery/master/usage/custom-resources.html#noderesourcetopology">NodeResourceTopology</a> custom resource object specific to this node. One instance of nfd-topology-updater is supposed to be running on each node of the cluster.</p> <h2 id="nfd-gc">NFD-GC</h2> <p>NFD-GC is a daemon responsible for cleaning obsolete <a href="/node-feature-discovery/master/usage/custom-resources.html#nodefeature">NodeFeature</a> and <a href="/node-feature-discovery/master/usage/custom-resources.html#noderesourcetopology">NodeResourceTopology</a> objects.</p> <p>One instance of nfd-gc is supposed to be running in the cluster.</p> <h2 id="feature-discovery">Feature Discovery</h2> <p>Feature discovery is divided into domain-specific feature sources:</p> <ul> <li>CPU</li> <li>Kernel</li> <li>Memory</li> <li>Network</li> <li>PCI</li> <li>Storage</li> <li>System</li> <li>USB</li> <li>Custom (rule-based custom features)</li> <li>Local (hooks for user-specific features)</li> </ul> <p>Each feature source is responsible for detecting a set of features which. in turn, are turned into node feature labels. Feature labels are prefixed with <code class="language-plaintext highlighter-rouge notranslate">feature.node.kubernetes.io/</code> and also contain the name of the feature source. Non-standard user-specific feature labels can be created with the local and custom feature sources.</p> <p>An overview of the default feature labels:</p> <div class="language-json highlighter-rouge notranslate"><div class="highlight"><pre class="highlight"><code><span class="p">{</span><span class="w">

It detects hardware features available on each node in a Kubernetes cluster, and advertises those features using node labels and optionally node extended resources, annotations and node taints. Node Feature Discovery is compatible with any recent version of Kubernetes (v1.21+).</p> <p>NFD consists of four software components:</p> <ol> <li>nfd-master</li> <li>nfd-worker</li> <li>nfd-topology-updater</li> <li>nfd-gc</li> </ol> <h2 id="nfd-master">NFD-Master</h2> <p>NFD-Master is the daemon responsible for communication towards the Kubernetes API. That is, it receives labeling requests from the worker and modifies node objects accordingly.</p> <h2 id="nfd-worker">NFD-Worker</h2> <p>NFD-Worker is a daemon responsible for feature detection. It then communicates the information to nfd-master which does the actual node labeling. One instance of nfd-worker is supposed to be running on each node of the cluster,</p> <h2 id="nfd-topology-updater">NFD-Topology-Updater</h2> <p>NFD-Topology-Updater is a daemon responsible for examining allocated resources on a worker node to account for resources available to be allocated to new pod on a per-zone basis (where a zone can be a NUMA node). It then creates or updates a <a href="/node-feature-discovery/master/usage/custom-resources.html#noderesourcetopology">NodeResourceTopology</a> custom resource object specific to this node. One instance of nfd-topology-updater is supposed to be running on each node of the cluster.</p> <h2 id="nfd-gc">NFD-GC</h2> <p>NFD-GC is a daemon responsible for cleaning obsolete <a href="/node-feature-discovery/master/usage/custom-resources.html#nodefeature">NodeFeature</a> and <a href="/node-feature-discovery/master/usage/custom-resources.html#noderesourcetopology">NodeResourceTopology</a> objects.</p> <p>One instance of nfd-gc is supposed to be running in the cluster.</p> <h2 id="feature-discovery">Feature Discovery</h2> <p>Feature discovery is divided into domain-specific feature sources:</p> <ul> <li>CPU</li> <li>Kernel</li> <li>Memory</li> <li>Network</li> <li>PCI</li> <li>Storage</li> <li>System</li> <li>USB</li> <li>Custom (rule-based custom features)</li> <li>Local (hooks for user-specific features)</li> </ul> <p>Each feature source is responsible for detecting a set of features which. in turn, are turned into node feature labels. Feature labels are prefixed with <code class="language-plaintext highlighter-rouge notranslate">feature.node.kubernetes.io/</code> and also contain the name of the feature source. Non-standard user-specific feature labels can be created with the local and custom feature sources.</p> <p>An overview of the default feature labels:</p> <div class="language-json highlighter-rouge notranslate"><div class="highlight"><pre class="highlight"><code><span class="p">{</span><span class="w">

</ul> <h2 id="nodefeature-custom-resource">NodeFeature custom resource</h2> <p>NodeFeature objects provide a way for 3rd party extensions to advertise custom features, both as "raw" features that serve as input to <a href="#nodefeaturerule-custom-resource">NodeFeatureRule</a> objects and as feature labels directly.</p> <p>Note that RBAC rules must be created for each extension for them to be able to create and manipulate NodeFeature objects in their namespace.</p> <p>The NodeFeature CRD API can be disabled with the <a href="/node-feature-discovery/master/reference/feature-gates.html#nodefeatureapi">NodeFeatureAPI</a> feature gate (<code class="language-plaintext highlighter-rouge notranslate">-feature-gates NodeFeatureAPI=false</code> on command line). The <code class="language-plaintext highlighter-rouge notranslate">-feature-gates</code> command line flag must be specified for both nfd-master and nfd-worker as it will enable the gRPC communication between them. Note that the gRPC API is <strong>DEPRECATED</strong> and will be removed in a future release, at which point the NodeFeature API cannot be disabled.</p> <h3 id="a-nodefeature-example">A NodeFeature example</h3> <p>Consider the following referential example:</p> <div class="language-yaml highlighter-rouge notranslate"><div class="highlight"><pre class="highlight"><code><span class="na">apiVersion</span><span class="pi">:</span> <span class="s">nfd.k8s-sigs.io/v1alpha1</span>

</ul> <h2 id="nodefeature-custom-resource">NodeFeature custom resource</h2> <p>NodeFeature objects provide a way for 3rd party extensions to advertise custom features, both as "raw" features that serve as input to <a href="#nodefeaturerule-custom-resource">NodeFeatureRule</a> objects and as feature labels directly.</p> <p>Note that RBAC rules must be created for each extension for them to be able to create and manipulate NodeFeature objects in their namespace.</p> <p>The NodeFeature CRD API can be disabled with the <a href="/node-feature-discovery/master/reference/feature-gates.html#nodefeatureapi">NodeFeatureAPI</a> feature gate (<code class="language-plaintext highlighter-rouge notranslate">-feature-gates NodeFeatureAPI=false</code> on command line). The <code class="language-plaintext highlighter-rouge notranslate">-feature-gates</code> command line flag must be specified for both nfd-master and nfd-worker as it will enable the gRPC communication between them. Note that the gRPC API is <strong>DEPRECATED</strong> and will be removed in a future release, at which point the NodeFeature API cannot be disabled.</p> <h3 id="a-nodefeature-example">A NodeFeature example</h3> <p>Consider the following referential example:</p> <div class="language-yaml highlighter-rouge notranslate"><div class="highlight"><pre class="highlight"><code><span class="na">apiVersion</span><span class="pi">:</span> <span class="s">nfd.k8s-sigs.io/v1alpha1</span>

This assures re-examination on regular intervals and/or per pod life-cycle events, capturing changes in the allocated resources and hence the allocatable resources on a per-zone basis by updating <a href="/node-feature-discovery/master/usage/custom-resources.html#noderesourcetopology">NodeResourceTopology</a> custom resources. It makes sure that new NodeResourceTopology instances are created for each new nodes that get added to the cluster.</p> <p>Because of the design and implementation of Kubernetes, only resources exclusively allocated to <a href="https://kubernetes.io/docs/concepts/workloads/pods/pod-qos/#guaranteed">Guaranteed Quality of Service</a> pods will be accounted. This includes <a href="https://kubernetes.io/docs/tasks/administer-cluster/cpu-management-policies/#static-policy">CPU cores</a>, <a href="https://kubernetes.io/docs/tasks/administer-cluster/memory-manager/#policy-static">memory</a> and <a href="https://kubernetes.io/docs/concepts/extend-kubernetes/compute-storage-net/device-plugins/">devices</a>.</p> <p>When run as a daemonset, nodes are re-examined for the allocated resources (to determine the information of the allocatable resources on a per-zone basis where a zone can be a NUMA node) at an interval specified using the <a href="../reference/topology-updater-commandline-reference.html.md#-sleep-interval"><code class="language-plaintext highlighter-rouge notranslate">-sleep-interval</code></a> option. The default sleep interval is set to 60s which is the value when no -sleep-interval is specified. The re-examination can be disabled by setting the sleep-interval to 0.</p> <p>Another option is to configure the updater to update the allocated resources per pod life-cycle events. The updater will monitor the checkpoint file stated in <a href="/node-feature-discovery/master/reference/topology-updater-commandline-reference.html#-kubelet-state-dir"><code class="language-plaintext highlighter-rouge notranslate">-kubelet-state-dir</code></a> and triggers an update for every change occurs in the files.</p> <p>In addition, it can avoid examining specific allocated resources given a configuration of resources to exclude via <a href="/node-feature-discovery/master/reference/topology-updater-configuration-reference.html#excludelist"><code class="language-plaintext highlighter-rouge notranslate">-excludeList</code></a></p> <h2 id="deployment-notes">Deployment Notes</h2> <p>Kubelet <a href="https://kubernetes.io/docs/concepts/extend-kubernetes/compute-storage-net/device-plugins/#monitoring-device-plugin-resources">PodResource API</a> with the <a href="https://kubernetes.io/docs/concepts/extend-kubernetes/compute-storage-net/device-plugins/#grpc-endpoint-getallocatableresources">GetAllocatableResources</a> functionality enabled is a prerequisite for nfd-topology-updater to be able to run (i.e. Kubernetes v1.21 or later is required).</p> <p>Preceding Kubernetes v1.23, the <code class="language-plaintext highlighter-rouge notranslate">kubelet</code> must be started with <code class="language-plaintext highlighter-rouge notranslate">--feature-gates=KubeletPodResourcesGetAllocatable=true</code>.</p> <p>Starting from Kubernetes v1.23, the <code class="language-plaintext highlighter-rouge notranslate">KubeletPodResourcesGetAllocatable</code> <a href="https://kubernetes.io/docs/reference/command-line-tools-reference/feature-gates">feature gate</a>. is enabled by default</p> <h2 id="topology-updater-configuration">Topology-Updater Configuration</h2> <p>NFD-Topology-Updater supports configuration through a configuration file. The default location is <code class="language-plaintext highlighter-rouge notranslate">/etc/kubernetes/node-feature-discovery/topology-updater.conf</code>, but, this can be changed by specifying the<code class="language-plaintext highlighter-rouge notranslate">-config</code> command line flag.</p> <blockquote> <p><strong>NOTE:</strong> unlike nfd-worker, dynamic configuration updates are not supported.</p> </blockquote> <p>Topology-Updater configuration file is read inside the container, and thus, Volumes and VolumeMounts are needed to make your configuration available for NFD. The preferred method is to use a ConfigMap which provides easy deployment and re-configurability.</p> <p>The provided nfd-topology-updater deployment templates create an empty configmap and mount it inside the nfd-topology-updater containers. In kustomize deployments, configuration can be edited with:</p> <div class="language-bash highlighter-rouge notranslate"><div class="highlight"><pre class="highlight"><code>kubectl <span class="nt">-n</span> <span class="k">${</span><span class="nv">NFD_NS</span><span class="k">}</span> edit configmap nfd-topology-updater-conf

This assures re-examination on regular intervals and/or per pod life-cycle events, capturing changes in the allocated resources and hence the allocatable resources on a per-zone basis by updating <a href="/node-feature-discovery/master/usage/custom-resources.html#noderesourcetopology">NodeResourceTopology</a> custom resources. It makes sure that new NodeResourceTopology instances are created for each new nodes that get added to the cluster.</p> <p>Because of the design and implementation of Kubernetes, only resources exclusively allocated to <a href="https://kubernetes.io/docs/concepts/workloads/pods/pod-qos/#guaranteed">Guaranteed Quality of Service</a> pods will be accounted. This includes <a href="https://kubernetes.io/docs/tasks/administer-cluster/cpu-management-policies/#static-policy">CPU cores</a>, <a href="https://kubernetes.io/docs/tasks/administer-cluster/memory-manager/#policy-static">memory</a> and <a href="https://kubernetes.io/docs/concepts/extend-kubernetes/compute-storage-net/device-plugins/">devices</a>.</p> <p>When run as a daemonset, nodes are re-examined for the allocated resources (to determine the information of the allocatable resources on a per-zone basis where a zone can be a NUMA node) at an interval specified using the <a href="../reference/topology-updater-commandline-reference.html.md#-sleep-interval"><code class="language-plaintext highlighter-rouge notranslate">-sleep-interval</code></a> option. The default sleep interval is set to 60s which is the value when no -sleep-interval is specified. The re-examination can be disabled by setting the sleep-interval to 0.</p> <p>Another option is to configure the updater to update the allocated resources per pod life-cycle events. The updater will monitor the checkpoint file stated in <a href="/node-feature-discovery/master/reference/topology-updater-commandline-reference.html#-kubelet-state-dir"><code class="language-plaintext highlighter-rouge notranslate">-kubelet-state-dir</code></a> and triggers an update for every change occurs in the files.</p> <p>In addition, it can avoid examining specific allocated resources given a configuration of resources to exclude via <a href="/node-feature-discovery/master/reference/topology-updater-configuration-reference.html#excludelist"><code class="language-plaintext highlighter-rouge notranslate">-excludeList</code></a></p> <h2 id="deployment-notes">Deployment Notes</h2> <p>Kubelet <a href="https://kubernetes.io/docs/concepts/extend-kubernetes/compute-storage-net/device-plugins/#monitoring-device-plugin-resources">PodResource API</a> with the <a href="https://kubernetes.io/docs/concepts/extend-kubernetes/compute-storage-net/device-plugins/#grpc-endpoint-getallocatableresources">GetAllocatableResources</a> functionality enabled is a prerequisite for nfd-topology-updater to be able to run (i.e. Kubernetes v1.21 or later is required).</p> <p>Preceding Kubernetes v1.23, the <code class="language-plaintext highlighter-rouge notranslate">kubelet</code> must be started with <code class="language-plaintext highlighter-rouge notranslate">--feature-gates=KubeletPodResourcesGetAllocatable=true</code>.</p> <p>Starting from Kubernetes v1.23, the <code class="language-plaintext highlighter-rouge notranslate">KubeletPodResourcesGetAllocatable</code> <a href="https://kubernetes.io/docs/reference/command-line-tools-reference/feature-gates">feature gate</a>. is enabled by default</p> <h2 id="topology-updater-configuration">Topology-Updater Configuration</h2> <p>NFD-Topology-Updater supports configuration through a configuration file. The default location is <code class="language-plaintext highlighter-rouge notranslate">/etc/kubernetes/node-feature-discovery/topology-updater.conf</code>, but, this can be changed by specifying the<code class="language-plaintext highlighter-rouge notranslate">-config</code> command line flag.</p> <blockquote> <p><strong>NOTE:</strong> unlike nfd-worker, dynamic configuration updates are not supported.</p> </blockquote> <p>Topology-Updater configuration file is read inside the container, and thus, Volumes and VolumeMounts are needed to make your configuration available for NFD. The preferred method is to use a ConfigMap which provides easy deployment and re-configurability.</p> <p>The provided nfd-topology-updater deployment templates create an empty configmap and mount it inside the nfd-topology-updater containers. In kustomize deployments, configuration can be edited with:</p> <div class="language-bash highlighter-rouge notranslate"><div class="highlight"><pre class="highlight"><code>kubectl <span class="nt">-n</span> <span class="k">${</span><span class="nv">NFD_NS</span><span class="k">}</span> edit configmap nfd-topology-updater-conf
</code></pre> </div></div> <p>In Helm deployments, <a href="/node-feature-discovery/master/deployment/helm.html#topology-updater-parameters">Topology Updater parameters</a> <code class="language-plaintext highlighter-rouge notranslate">toplogyUpdater.config</code> can be used to edit the respective configuration.</p> <p>See <a href="/node-feature-discovery/master/reference/topology-updater-configuration-reference.html">nfd-topology-updater configuration file reference</a> for more details.

This assures re-labeling on regular intervals capturing changes in the system configuration and makes sure that new nodes are labeled as they are added to the cluster. Worker connects to the nfd-master service to advertise hardware features.</p> <p>When run as a daemonset, nodes are re-labeled at an default interval of 60s. This can be changed by using the <a href="/node-feature-discovery/master/reference/worker-configuration-reference.html#coresleepinterval"><code class="language-plaintext highlighter-rouge notranslate">core.sleepInterval</code></a> config option.</p> <p>The worker configuration file is watched and re-read on every change which provides a mechanism of dynamic run-time reconfiguration. See <a href="#worker-configuration">worker configuration</a> for more details.</p> <h2 id="worker-configuration">Worker configuration</h2> <p>NFD-Worker supports dynamic configuration through a configuration file. The default location is <code class="language-plaintext highlighter-rouge notranslate">/etc/kubernetes/node-feature-discovery/nfd-worker.conf</code>, but, this can be changed by specifying the<code class="language-plaintext highlighter-rouge notranslate">-config</code> command line flag. Configuration file is re-read whenever it is modified which makes run-time re-configuration of nfd-worker straightforward.</p> <p>Worker configuration file is read inside the container, and thus, Volumes and VolumeMounts are needed to make your configuration available for NFD. The preferred method is to use a ConfigMap which provides easy deployment and re-configurability.</p> <p>The provided nfd-worker deployment templates create an empty configmap and mount it inside the nfd-worker containers. In kustomize deployments, configuration can be edited with:</p> <div class="language-bash highlighter-rouge notranslate"><div class="highlight"><pre class="highlight"><code>kubectl <span class="nt">-n</span> <span class="k">${</span><span class="nv">NFD_NS</span><span class="k">}</span> edit configmap nfd-worker-conf

This assures re-labeling on regular intervals capturing changes in the system configuration and makes sure that new nodes are labeled as they are added to the cluster. Worker connects to the nfd-master service to advertise hardware features.</p> <p>When run as a daemonset, nodes are re-labeled at an default interval of 60s. This can be changed by using the <a href="/node-feature-discovery/master/reference/worker-configuration-reference.html#coresleepinterval"><code class="language-plaintext highlighter-rouge notranslate">core.sleepInterval</code></a> config option.</p> <p>The worker configuration file is watched and re-read on every change which provides a mechanism of dynamic run-time reconfiguration. See <a href="#worker-configuration">worker configuration</a> for more details.</p> <h2 id="worker-configuration">Worker configuration</h2> <p>NFD-Worker supports dynamic configuration through a configuration file. The default location is <code class="language-plaintext highlighter-rouge notranslate">/etc/kubernetes/node-feature-discovery/nfd-worker.conf</code>, but, this can be changed by specifying the<code class="language-plaintext highlighter-rouge notranslate">-config</code> command line flag. Configuration file is re-read whenever it is modified which makes run-time re-configuration of nfd-worker straightforward.</p> <p>Worker configuration file is read inside the container, and thus, Volumes and VolumeMounts are needed to make your configuration available for NFD. The preferred method is to use a ConfigMap which provides easy deployment and re-configurability.</p> <p>The provided nfd-worker deployment templates create an empty configmap and mount it inside the nfd-worker containers. In kustomize deployments, configuration can be edited with:</p> <div class="language-bash highlighter-rouge notranslate"><div class="highlight"><pre class="highlight"><code>kubectl <span class="nt">-n</span> <span class="k">${</span><span class="nv">NFD_NS</span><span class="k">}</span> edit configmap nfd-worker-conf
</code></pre> </div></div> <p>In Helm deployments, <a href="/node-feature-discovery/master/deployment/helm.html#worker-pod-parameters">Worker pod parameter</a> <code class="language-plaintext highlighter-rouge notranslate">worker.config</code> can be used to edit the respective configuration.</p> <p>See <a href="../reference/worker-configuration-reference">nfd-worker configuration file reference</a> for more details. The (empty-by-default) <a href="https://github.com/kubernetes-sigs/node-feature-discovery/blob/master/deployment/components/worker-config/nfd-worker.conf.example">example config</a> contains all available configuration options and can be used as a reference for creating a configuration.</p> <p>Configuration options can also be specified via the <code class="language-plaintext highlighter-rouge notranslate">-options</code> command line flag, in which case no mounts need to be used. The same format as in the config file must be used, i.e. JSON (or YAML). For example:</p> <div class="language-bash highlighter-rouge notranslate"><div class="highlight"><pre class="highlight"><code><span class="nt">-options</span><span class="o">=</span><span class="s1">'{"sources": { "pci": { "deviceClassWhitelist": ["12"] } } }'</span>
</code></pre> </div></div> <p>Configuration options specified from the command line will override those read from the config file.</p> </div> </div> <div class="navigation-bottom d-flex flex-justify-between py-3" role="navigation" aria-label="footer navigation"> <div class="prev"><a href="/node-feature-discovery/master/usage/nfd-master.html" class="btn" title="NFD-Master" accesskey="p" rel="prev"> <i class="fa fa-arrow-circle-left"></i> Previous </a></div> <div class="next"><a href="/node-feature-discovery/master/usage/nfd-topology-updater.html" class="btn" title="NFD-Topology-Updater" accesskey="n" rel="next"> Next <i class="fa fa-arrow-circle-right"></i> </a></div> </div><hr> <div class="copyright text-center text-gray" role="contentinfo"> <i class="fa fa-copyright"></i> <span class="time">2016-2024,</span> <a class="text-gray" href="https://github.com/kubernetes-sigs" rel="noreferrer" target="_blank">Kubernetes SIGs</a> Revision <a class="text-gray" href="https://github.com/kubernetes-sigs/node-feature-discovery/commit/" title="" rel="noreferrer" target="_blank"></a> <br> <div class="generator"> Built with <a href="https://pages.github.com" rel="noreferrer" target="_blank" title="github-pages v228">GitHub Pages</a> using a <a href="https://github.com/rundocs/jekyll-rtd-theme" rel="noreferrer" target="_blank" title="rundocs/jekyll-rtd-theme v2.0.10">theme</a> provided by <a href="https://rundocs.io" rel="noreferrer" target="_blank">RunDocs</a>. </div> </div> </div> </div> <div class="addons-wrap d-flex flex-column overflow-y-auto"> <div class="status d-flex flex-justify-between p-2"> <div class="title p-1"> <i class="fa fa-book"></i> Node Feature Discovery </div> <div class="branch p-1"> <span class="name"> master </span> <i class="fa fa-caret-down"></i> </div> </div> <div class="addons d-flex flex-column height-full p-2 d-none"> <dl id="versions"> <dt>Versions</dt> <script src="/node-feature-discovery/versions.js"></script> <script> var dt = document.getElementById('versions'); var items = getVersionListItems(); for (var i=0; i < items.length; i++) { var dd = document.createElement('dd'); var a = 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> <a href="https://github.com/kubernetes-sigs/node-feature-discovery" title="Stars: 685"> <i class="fa fa-github"></i> Homepage </a> </dd> <dd> <a href="https://github.com/kubernetes-sigs/node-feature-discovery/issues" title="Open issues: 26"> <i class="fa fa-question-circle-o"></i> Issues </a> </dd> <dd> <a href="https://github.com/kubernetes-sigs/node-feature-discovery/zipball/gh-pages" title="Size: 101349 Kb"> <i class="fa fa-download"></i> Download </a> </dd> </dl> <hr> <div class="license f6 pb-2"> This <a href="/node-feature-discovery/master/" title="Node Feature Discovery">Software</a> is under the terms of <a href="https://github.com/kubernetes-sigs/node-feature-discovery">Apache License 2.0</a>. </div> </div> </div> <script src="https://cdn.jsdelivr.net/gh/rundocs/jekyll-rtd-theme@2.0.10/assets/js/jquery.min.js"></script><script src="https://cdn.jsdelivr.net/gh/rundocs/jekyll-rtd-theme@2.0.10/assets/js/theme.min.js"></script> </body> </html>
