Similar to docker containers that have <code>overlayfs<\/code> root.<\/p>\n\n\n\n<p>You don&#8217;t have to think about redundancy and performing updates for your OS anymore! A simple reboot is enough to apply the new image!<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Declarative<\/h3>\n\n\n\n<p>You can spawn new Kubernetes clusters and PXE-servers just using Helm, very quickly! Just provide all the parameters in the wonderfully simple Yaml format.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Customizable<\/h3>\n\n\n\n<p>You can build your own image for the physical servers simply by just using a <a href=\"https:\/\/github.com\/kubefarm\/kubefarm\/blob\/master\/build\/ltsp\/Dockerfile\">Dockerfile<\/a>. The default image is based on Ubuntu. You can put anything you need! Simply add any additional packages and custom kernel modules, and initiate the build!<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Secure<\/h3>\n\n\n\n<p>You can deploy as many clusters as you want! All of them will have a separate control-plane, non visible to its consumers. Cert-manager will take care of the certificates.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Known components<\/h3>\n\n\n\n<p>The whole setup consists of a few components:<\/p>\n\n\n\n<ul>\n<li><strong><a href=\"https:\/\/github.com\/kubefarm\/kubernetes-in-kubernetes\">Kubernetes-in-Kubernetes<\/a><\/strong> &#8211; Kubernetes control-plane packed to a Helm-chart. It is based on the official Kubernetes static pod manifests and using the official Kubernetes docker images.<\/li>\n\n\n\n<li><strong><a href=\"https:\/\/github.com\/kubefarm\/dnsmasq-controller\">Dnsmasq-controller<\/a><\/strong> &#8211; A simple wrapper for <code>Dnsmasq<\/code>, which automates the configuration using Kubernetes CRDs and will perform leader-election for DHCP high availability.<\/li>\n\n\n\n<li><strong><a href=\"https:\/\/github.com\/ltsp\/ltsp\">LTSP<\/a><\/strong> &#8211; Network boot server and boot time configuration framework for clients. It allows you to boot the OS over the network, directly to RAM and perform initial configurations for each server.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Screenshots<\/h3>\n\n\n\n<div
