This page contains a list of commonly used kubectl commands and flags. Note:These instructions are for Kubernetes v1.34. 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:

symbol.contrib Contrib Symbol API of MXNet. Functions rand_zipfian (true_classes, num_sampled, …) Draw random samples...

Role-based access control (RBAC) is a method of regulating access to computer or network resources based on the roles of individual users within your organization. RBAC authorization uses the rbac.authorization.k8s.io API group to drive authorization decisions, allowing you to dynamically configure policies through the Kubernetes API. To enable RBAC, start the API server with the --authorization-config flag set to a file that includes the RBAC authorizer; for example: apiVersion: apiserver.

This page provides an overview of admission controllers. An admission controller is a piece of code that intercepts requests to the Kubernetes API server prior to persistence of the resource, but after the request is authenticated and authorized. Several important features of Kubernetes require an admission controller to be enabled in order to properly support the feature. As a result, a Kubernetes API server that is not properly configured with the right set of admission controllers is an incomplete server that will not support all the features you expect.

This page explains how to debug Pods running (or crashing) on a Node. Before you begin Your Pod should already be scheduled and running. If your Pod is not yet running, start with Debugging Pods. For some of the advanced debugging steps you need to know on which Node the Pod is running and have shell access to run commands on that Node. You don't need that access to run the standard debug steps that use kubectl.

In a Kubernetes cluster, the components on the worker nodes - kubelet and kube-proxy - need to communicate with Kubernetes control plane components, specifically kube-apiserver. In order to ensure that communication is kept private, not interfered with, and ensure that each component of the cluster is talking to another trusted component, we strongly recommend using client TLS certificates on nodes. The normal process of bootstrapping these components, especially worker nodes that need certificates so they can communicate safely with kube-apiserver, can be a challenging process as it is often outside of the scope of Kubernetes and requires significant additional work.

Overview Package v1beta3 defines the v1beta3 version of the kubeadm configuration file format. This version improves on the v1beta2 format by fixing some minor issues and adding a few new fields. A list of changes since v1beta2: The deprecated "ClusterConfiguration.useHyperKubeImage" field has been removed. Kubeadm no longer supports the hyperkube image. The "ClusterConfiguration.dns.type" field has been removed since CoreDNS is the only supported DNS server type by kubeadm. Include "datapolicy" tags on the fields that hold secrets.

FEATURE STATE: Kubernetes v1.33 [beta] Kubernetes 1.34 includes optional declarative validation for APIs. When enabled, the Kubernetes API server can use this mechanism rather than the legacy approach that relies on hand-written Go code (validation.go files) to ensure that requests against the API are valid. Kubernetes developers, and people extending the Kubernetes API, can define validation rules directly alongside the API type definitions (types.go files). Code authors define special comment tags (e.
