Cluster</h1></header><p>By using Rancher with vSphere, you can bring cloud operations on-premises.</p><p>Rancher can provision nodes in vSphere and install Kubernetes on them. When creating a Kubernetes cluster in vSphere, Rancher first provisions the specified number of virtual machines by communicating with the vCenter API. Then it installs Kubernetes on top of them.</p><p>A vSphere cluster may consist of multiple groups of VMs with distinct properties, such as the amount of memory or the number of vCPUs. This grouping allows for fine-grained control over the sizing of nodes for each Kubernetes role.</p><h2 class="anchor anchorWithStickyNavbar_LWe7" id="vsphere-enhancements-in-rancher-v23">vSphere Enhancements in Rancher v2.3<a href="#vsphere-enhancements-in-rancher-v23" class="hash-link" aria-label="Direct link to vSphere Enhancements in Rancher v2.3" title="Direct link to vSphere Enhancements in Rancher v2.3"></a></h2><p>The vSphere node templates have been updated, allowing you to bring cloud operations on-premises with the following enhancements:</p><h3 class="anchor anchorWithStickyNavbar_LWe7" id="self-healing-node-pools">Self-healing Node Pools<a href="#self-healing-node-pools" class="hash-link" aria-label="Direct link to Self-healing Node Pools" title="Direct link to Self-healing Node Pools"></a></h3><p>One of the biggest advantages of provisioning vSphere nodes with Rancher is that it allows you to take advantage of Rancher's self-healing node pools, also called the <a href="/pages-for-subheaders/use-new-nodes-in-an-infra-provider#about-node-auto-replace">node auto-replace feature,</a> in your on-premises clusters. Self-healing node pools are designed to help you replace worker nodes for stateless applications. When Rancher provisions nodes from a node template, Rancher can automatically replace unreachable nodes.</p><div class="theme-admonition theme-admonition-caution alert alert--warning admonition_LlT9"><div class="admonitionHeading_tbUL"><span class="admonitionIcon_kALy"><svg viewBox="0 0 16 16"><path fill-rule="evenodd" d="M8.893 1.5c-.183-.31-.52-.5-.887-.5s-.703.19-.886.5L.138 13.499a.98.98 0 0 0 0 1.001c.193.31.53.501.886.501h13.964c.367 0 .704-.19.877-.5a1.03 1.03 0 0 0 .01-1.002L8.893 1.5zm.133 11.497H6.987v-2.003h2.039v2.003zm0-3.004H6.987V5.987h2.039v4.006z"></path></svg></span>caution</div><div class="admonitionContent_S0QG"><p>It is not recommended to enable node auto-replace on a node pool of master nodes or nodes with persistent volumes attached, because VMs are treated ephemerally.
