This document details the deprecation policy for various facets of the system. Kubernetes is a large system with many components and many contributors. As with any such software, the feature set naturally evolves over time, and sometimes a feature may need to be removed. This could include an API, a flag, or even an entire feature. To avoid breaking existing users, Kubernetes follows a deprecation policy for aspects of the system that are slated to be removed.

Overview A kubelet's HTTPS endpoint exposes APIs which give access to data of varying sensitivity, and allow you to perform operations with varying levels of power on the node and within containers. This document describes how to authenticate and authorize access to the kubelet's HTTPS endpoint. Kubelet authentication By default, requests to the kubelet's HTTPS endpoint that are not rejected by other configured authentication methods are treated as anonymous requests, and given a username of system:anonymous and a group of system:unauthenticated.

Synopsis Create a LoadBalancer service with the specified name. kubectl create service loadbalancer NAME [--tcp=port:targetPort] [--dry-run=server|client|none] Examples # Create a new LoadBalancer service named my-lbs kubectl create service loadbalancer my-lbs --tcp=5678:8080 Options --allow-missing-template-keys     Default: true If true, ignore any errors in templates when a field or map key is missing in the template. Only applies to golang and jsonpath output formats. --dry-run string[="unchanged"]     Default: "none" Must be "none", "server", or "client". If client strategy, only print the object that would be sent, without sending it.

Synopsis Expose a resource as a new Kubernetes service. Looks up a deployment, service, replica set, replication controller or pod by name and uses the selector for that resource as the selector for a new service on the specified port. A deployment or replica set will be exposed as a service only if its selector is convertible to a selector that service supports, i.e. when the selector contains only the matchLabels component.

Synopsis Set the selector on a resource. Note that the new selector will overwrite the old selector if the resource had one prior to the invocation of 'set selector'. A selector must begin with a letter or number, and may contain letters, numbers, hyphens, dots, and underscores, up to 63 characters. If --resource-version is specified, then updates will use this resource version, otherwise the existing resource-version will be used. Note: currently selectors can only be set on Service objects.

Note:This page is being directed to https://v1-24.docs.kubernetes.io/docs/reference/tools/map-crictl-dockercli/ because of the removal of dockershim from crictl in v1.24. As per our community policy, deprecated documents are not maintained beyond next three versions. The reason for deprecation is explained in Dockershim-FAQ.

Anyone can write a blog post and submit it for review. Case studies require extensive review before they're approved. The Kubernetes Blog The Kubernetes blog is used by the project to communicate new features, community reports, and any news that might be relevant to the Kubernetes community. This includes end users and developers. Most of the blog's content is about things happening in the core project, but we encourage you to submit about things happening elsewhere in the ecosystem too!

Resource Types ExecCredential ExecCredential ExecCredential is used by exec-based plugins to communicate credentials to HTTP transports. FieldDescription apiVersionstringclient.authentication.k8s.io/v1 kindstringExecCredential spec [Required] ExecCredentialSpec Spec holds information passed to the plugin by the transport. status ExecCredentialStatus Status is filled in by the plugin and holds the credentials that the transport should use to contact the API. Cluster Appears in: ExecCredentialSpec Cluster contains information to allow an exec plugin to communicate with the kubernetes cluster being authenticated to.

This guide is for application owners who want to build highly available applications, and thus need to understand what types of disruptions can happen to Pods. It is also for cluster administrators who want to perform automated cluster actions, like upgrading and autoscaling clusters. Voluntary and involuntary disruptions Pods do not disappear until someone (a person or a controller) destroys them, or there is an unavoidable hardware or system software error.
