FEATURE STATE: Kubernetes v1.34 [beta] This page provides an overview of MutatingAdmissionPolicies. MutatingAdmissionPolicies allow you change what happens when someone writes a change to the Kubernetes API. If you want to use declarative policies just to prevent a particular kind of change to resources (for example: protecting platform namespaces from deletion), ValidatingAdmissionPolicy is a simpler and more effective alternative. To use the feature, enable the MutatingAdmissionPolicy feature gate (which is off by default) and set --runtime-config=admissionregistration.

Production-Grade Container Orchestration

FEATURE STATE: Kubernetes v1.26 [stable] Starting from Kubernetes v1.20, the kubelet can dynamically retrieve credentials for a container image registry using exec plugins. The kubelet and the exec plugin communicate through stdio (stdin, stdout, and stderr) using Kubernetes versioned APIs. These plugins allow the kubelet to request credentials for a container registry dynamically as opposed to storing static credentials on disk. For example, the plugin may talk to a local metadata server to retrieve short-lived credentials for an image that is being pulled by the kubelet.

FastAPI framework, high performance, easy to learn, fast to code, ready for production

This tutorial shows you how to build and deploy a simple (not production ready), multi-tier web application using Kubernetes and Docker. This example consists of the following components: A single-instance Redis to store guestbook entries Multiple web frontend instances Objectives Start up a Redis leader. Start up two Redis followers. Start up the guestbook frontend. Expose and view the Frontend Service. Clean up. Before you begin You need to have a Kubernetes cluster, and the kubectl command-line tool must be configured to communicate with your cluster.

A ServiceAccount provides an identity for processes that run in a Pod. A process inside a Pod can use the identity of its associated service account to authenticate to the cluster's API server. For an introduction to service accounts, read configure service accounts. This task guide explains some of the concepts behind ServiceAccounts. The guide also explains how to obtain or revoke tokens that represent ServiceAccounts, and how to (optionally) bind a ServiceAccount's validity to the lifetime of an API object.

Synopsis The Kubernetes API server validates and configures data for the api objects which include pods, services, replicationcontrollers, and others. The API Server services REST operations and provides the frontend to the cluster's shared state through which all other components interact. kube-apiserver [flags] Options --admission-control-config-file string File with admission control configuration. --advertise-address string The IP address on which to advertise the apiserver to members of the cluster. This address must be reachable by the rest of the cluster.
