Let’s create a Virtual Kubernetes cluster with System-upgrade-controller installed in it in just 100 Seconds with Klusternetes(KNTS)
system-upgrade-controller aims to provide a general-purpose, Kubernetes-native upgrade controller (for nodes). It introduces a new CRD, the Plan, for defining any and all of your upgrade policies/requirements.
Klusternetes is a platform that allows you to create a Kubernetes cluster in a few seconds. It also provides some of the leading DevOps tools as add-ons while creating your Cluster and provides a Service URL for add-ons that have UI.
