Principles and practices for good RBAC design for cluster operators.

API-initiated eviction is the process by which you use the Eviction API to create an Eviction object that triggers graceful pod termination. You can request eviction by calling the Eviction API directly, or programmatically using a client of the API server, like the kubectl drain command. This creates an Eviction object, which causes the API server to terminate the Pod. API-initiated evictions respect your configured PodDisruptionBudgets and terminationGracePeriodSeconds. Using the API to create an Eviction object for a Pod is like performing a policy-controlled DELETE operation on the Pod.

FEATURE STATE: Kubernetes v1.18 [beta] This page explains how to add Windows worker nodes to a kubeadm cluster. Before you begin A running Windows Server 2022 (or higher) instance with administrative access. A running kubeadm cluster created by kubeadm init and following the steps in the document Creating a cluster with kubeadm. Adding Windows worker nodes Note:To facilitate the addition of Windows worker nodes to a cluster, PowerShell scripts from the repository https://sigs.

This page provides a walkthrough for some steps you can follow to run Windows containers using Kubernetes. The page also highlights some Windows specific functionality within Kubernetes. It is important to note that creating and deploying services and workloads on Kubernetes behaves in much the same way for Linux and Windows containers. The kubectl commands to interface with the cluster are identical. The examples in this page are provided to jumpstart your experience with Windows containers.

Declarative and imperative paradigms for interacting with the Kubernetes API.

Run and manage both stateless and stateful applications.

This task shows you how to debug a StatefulSet. Before you begin You need to have a Kubernetes cluster, and the kubectl command-line tool must be configured to communicate with your cluster. You should have a StatefulSet running that you want to investigate. Debugging a StatefulSet In order to list all the pods which belong to a StatefulSet, which have a label app.kubernetes.io/name=MyApp set on them, you can use the following:

Managing confidential settings data using Secrets.

kubeadm does not support automated ways of reconfiguring components that were deployed on managed nodes. One way of automating this would be by using a custom operator. To modify the components configuration you must manually edit associated cluster objects and files on disk. This guide shows the correct sequence of steps that need to be performed to achieve kubeadm cluster reconfiguration. Before you begin You need a cluster that was deployed using kubeadm Have administrator credentials (/etc/kubernetes/admin.
