Using kubeadm, you can create a minimum viable Kubernetes cluster that conforms to best practices. In fact, you can use kubeadm to set up a cluster that will pass the Kubernetes Conformance tests. kubeadm also supports other cluster lifecycle functions, such as bootstrap tokens and cluster upgrades. The kubeadm tool is good if you need: A simple way for you to try out Kubernetes, possibly for the first time. A way for existing users to automate setting up a cluster and test their application.

Principles and practices for good RBAC design for cluster operators.

FEATURE STATE: Kubernetes v1.31 [alpha] (enabled by default: false) Kubernetes 1.32 includes an alpha feature that allows control plane components to deterministically select a leader via coordinated leader election. This is useful to satisfy Kubernetes version skew constraints during cluster upgrades. Currently, the only builtin selection strategy is OldestEmulationVersion, preferring the leader with the lowest emulation version, followed by binary version, followed by creation timestamp. Enabling coordinated leader election Ensure that CoordinatedLeaderElection feature gate is enabled when you start the API Server: and that the coordination.

Different ways to change the behavior of your Kubernetes cluster.

This page shows how to enable and configure autoscaling of the DNS service in your Kubernetes cluster. Before you begin You need to have a Kubernetes cluster, and the kubectl command-line tool must be configured to communicate with your cluster. It is recommended to run this tutorial on a cluster with at least two nodes that are not acting as control plane hosts. If you do not already have a cluster, you can create one by using minikube or you can use one of these Kubernetes playgrounds:
