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 example of how to provision and configure swap memory on a Kubernetes node using kubeadm. Objectives Provision swap memory on a Kubernetes node using kubeadm. Learn to configure both encrypted and unencrypted swap. Learn to enable swap on boot. Before you begin You need to have a Kubernetes cluster, and the kubectl command-line tool must be configured to communicate with your cluster. It is recommended to run this tutorial on a cluster with at least two nodes that are not acting as control plane hosts.

Synopsis Set a context entry in kubeconfig. Specifying a name that already exists will merge new fields on top of existing values for those fields. kubectl config set-context [NAME | --current] [--cluster=cluster_nickname] [--user=user_nickname] [--namespace=namespace] Examples # Set the user field on the gce context entry without touching other values kubectl config set-context gce --user=cluster-admin Options --cluster string cluster for the context entry in kubeconfig --current Modify the current context

This page contains information about the kubernetes.io analytics dashboard. View the dashboard. This dashboard is built using Google Looker Studio and shows information collected on kubernetes.io using Google Analytics 4 since August 2022. Using the dashboard By default, the dashboard shows all collected analytics for the past 30 days. Use the date selector to see data from a different date range. Other filtering options allow you to view data based on user location, the device used to access the site, the translation of the docs used, and more.

This page shows how to generate the kubectl command reference. Note:This topic shows how to generate reference documentation for kubectl commands like kubectl apply and kubectl taint. This topic does not show how to generate the kubectl options reference page. For instructions on how to generate the kubectl options reference page, see Generating Reference Pages for Kubernetes Components and Tools. Before you begin Requirements: You need a machine that is running Linux or macOS.

Resource Types Preference Preference Preference stores elements of KubeRC configuration file FieldDescription apiVersionstringkubectl.config.k8s.io/v1beta1 kindstringPreference defaults [Required] []CommandDefaults defaults allow changing default option values of commands. This is especially useful, when user doesn't want to explicitly set options each time. aliases [Required] []AliasOverride aliases allow defining command aliases for existing kubectl commands, with optional default option values. If the alias name collides with a built-in command, built-in command always takes precedence. Option overrides defined in the defaults section do NOT apply to aliases for the same command.

This page contains an overview of the client libraries for using the Kubernetes API from various programming languages. To write applications using the Kubernetes REST API, you do not need to implement the API calls and request/response types yourself. You can use a client library for the programming language you are using. Client libraries often handle common tasks such as authentication for you. Most client libraries can discover and use the Kubernetes Service Account to authenticate if the API client is running inside the Kubernetes cluster, or can understand the kubeconfig file format to read the credentials and the API Server address.

Bootstrap tokens are used for establishing bidirectional trust between a node joining the cluster and a control-plane node, as described in authenticating with bootstrap tokens. kubeadm init creates an initial token with a 24-hour TTL. The following commands allow you to manage such a token and also to create and manage new ones. kubeadm token create Create bootstrap tokens on the server Synopsis This command will create a bootstrap token for you.
