Legacy API for managing workloads that can scale horizontally. Superseded by the Deployment and ReplicaSet APIs.

Understand Pods, the smallest deployable compute object in Kubernetes, and the higher-level abstractions that help you to run them.

Kubernetes objects can be created, updated, and deleted by storing multiple object configuration files in a directory and using kubectl apply to recursively create and update those objects as needed. This method retains writes made to live objects without merging the changes back into the object configuration files. kubectl diff also gives you a preview of what changes apply will make. Before you begin Install kubectl. You need to have a Kubernetes cluster, and the kubectl command-line tool must be configured to communicate with your cluster.

AdmissionRequest Appears in: AdmissionReview AdmissionRequest describes the admission.Attributes for the admission request. FieldDescription uid [Required] k8s.io/apimachinery/pkg/types.UID UID is an identifier for the individual request/response. It allows us to distinguish instances of requests which are otherwise identical (parallel requests, requests when earlier requests did not modify etc) The UID is meant to track the round trip (request/response) between the KAS and the WebHook, not the user request.

There are two official Kubernetes blogs, and the CNCF has its own blog where you can cover Kubernetes too. Read contributing to Kubernetes blogs to learn about these two blogs. When people contribute to either blog as an author, the Kubernetes project pairs up authors as writing buddies. This page explains how to fulfil the buddy role. You should make sure that you have at least read an outline of article submission before you read on within this page.

This page shows you how to localize the docs for a different language. Contribute to an existing localization You can help add or improve the content of an existing localization. In Kubernetes Slack, you can find a channel for each localization. There is also a general SIG Docs Localizations Slack channel where you can say hello. Note:For extra details on how to contribute to a specific localization, look for a localized version of this page.

Alongside the PR Wrangler, formal approvers, reviewers and members of SIG Docs take week-long shifts triaging and categorising issues for the repository. Duties Each day in a week-long shift the Issue Wrangler will be responsible for: Triaging and tagging incoming issues daily. See Triage and categorize issues for guidelines on how SIG Docs uses metadata. Keeping an eye on stale & rotten issues within the kubernetes/website repository. Maintenance of the Issues board.

The Kubernetes documentation follows several types of page content: Concept Task Tutorial Reference Content sections Each page content type contains a number of sections defined by Markdown comments and HTML headings. You can add content headings to your page with the heading shortcode. The comments and headings help maintain the structure of the page content types. Examples of Markdown comments defining page content sections: <!-- overview --> <!-- body --> To create common headings in your content pages, use the heading shortcode with a heading string.

SIG Docs approvers take week-long shifts managing pull requests for the repository. This section covers the duties of a PR wrangler. For more information on giving good reviews, see Reviewing changes. Duties Each day in a week-long shift as PR Wrangler: Review open pull requests for quality and adherence to the Style and Content guides. Start with the smallest PRs (size/XS) first, and end with the largest (size/XXL). Review as many PRs as you can.
