This page explains the two options for configuring the topology of your highly available (HA) Kubernetes clusters. You can set up an HA cluster: With stacked control plane nodes, where etcd nodes are colocated with control plane nodes With external etcd nodes, where etcd runs on separate nodes from the control plane You should carefully consider the advantages and disadvantages of each topology before setting up an HA cluster.

Baseline checklist for ensuring security in Kubernetes clusters.

FEATURE STATE: Kubernetes v1.33 [beta] (enabled by default: true) This page shows how to configure a user namespace for pods. This allows you to isolate the user running inside the container from the one in the host. A process running as root in a container can run as a different (non-root) user in the host; in other words, the process has full privileges for operations inside the user namespace, but is unprivileged for operations outside the namespace.

This guide demonstrates how to access the Kubernetes API from within a pod. 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:

Note: This section links to third party projects that provide functionality required by Kubernetes. The Kubernetes project authors aren't responsible for these projects, which are listed alphabetically. To add a project to this list, read the content guide before submitting a change. More information. Kubernetes applications usually consist of multiple, separate services, each running in its own container. Developing and debugging these services on a remote Kubernetes cluster can be cumbersome, requiring you to get a shell on a running container in order to run debugging tools.

This page shows how to investigate problems related to the execution of Init Containers. The example command lines below refer to the Pod as <pod-name> and the Init Containers as <init-container-1> and <init-container-2>.
