Production-Grade Container Orchestration

Production-Grade Container Orchestration

This guide shows you how to create, edit and share diagrams using the Mermaid JavaScript library. Mermaid.js allows you to generate diagrams using a simple markdown-like syntax inside Markdown files. You can also use Mermaid to generate .svg or .png image files that you can add to your documentation. The target audience for this guide is anybody wishing to learn about Mermaid and/or how to create and add diagrams to Kubernetes documentation.

FEATURE STATE: Kubernetes v1.30 [stable] This page provides an overview of Validating Admission Policy. What is Validating Admission Policy? Validating admission policies offer a declarative, in-process alternative to validating admission webhooks. Validating admission policies use the Common Expression Language (CEL) to declare the validation rules of a policy. Validation admission policies are highly configurable, enabling policy authors to define policies that can be parameterized and scoped to resources as needed by cluster administrators.

This page contains a list of commonly used kubectl commands and flags. Note:These instructions are for Kubernetes v1.35. To check the version, use the kubectl version command. Kubectl autocomplete BASH source <(kubectl completion bash) # set up autocomplete in bash into the current shell, bash-completion package should be installed first. echo "source <(kubectl completion bash)" >> ~/.bashrc # add autocomplete permanently to your bash shell. You can also use a shorthand alias for kubectl that also works with completion:

kubeadm kubeconfig provides utilities for managing kubeconfig files. For examples on how to use kubeadm kubeconfig user see Generating kubeconfig files for additional users. kubeadm kubeconfig overview Synopsis Kubeconfig file utilities. Options -h, --help help for kubeconfig Options inherited from parent commands --rootfs string The path to the 'real' host root filesystem. This will cause kubeadm to chroot into the provided path. kubeadm kubeconfig user This command can be used to output a kubeconfig file for an additional user.

Synopsis kubectl controls the Kubernetes cluster manager. Find more information in Command line tool (kubectl). kubectl [flags] Options --add-dir-header If true, adds the file directory to the header of the log messages --alsologtostderr log to standard error as well as files --as string Username to impersonate for the operation --as-group stringArray Group to impersonate for the operation, this flag can be repeated to specify multiple groups. --azure-container-registry-config string Path to the file containing Azure container registry configuration information.

Recommended usage conventions for kubectl. Using kubectl in Reusable Scripts For a stable output in a script: Request one of the machine-oriented output forms, such as -o name, -o json, -o yaml, -o go-template, or -o jsonpath. Fully-qualify the version. For example, jobs.v1.batch/myjob. This will ensure that kubectl does not use its default version that can change over time. Don't rely on context, preferences, or other implicit states. Subresources You can use the --subresource argument for kubectl subcommands such as get, patch, edit, apply and replace to fetch and update subresources for all resources that support them.

Package v1beta1 is the v1beta1 version of the metrics API.

FieldDescription apiVersionstringmetrics.k8s.io/v1beta1 kindstringNodeMetrics metadata meta/v1.ObjectMeta Standard object's metadata. More info: https://git.k8s.io/community/contributors/devel/sig-architecture/api-conventions.md#metadata Refer to the Kubernetes API documentation for the fields of the metadata field. timestamp [Required] meta/v1.Time The following fields define time interval from which metrics were collected from the interval [Timestamp-Window, Timestamp].

Kubernetes provides a certificates.k8s.io API, which lets you provision TLS certificates signed by a Certificate Authority (CA) that you control. These CA and certificates can be used by your workloads to establish trust. certificates.k8s.io API uses a protocol that is similar to the ACME draft. Note:Certificates created using the certificates.k8s.io API are signed by a dedicated CA. It is possible to configure your cluster to use the cluster root CA for this purpose, but you should never rely on this.
