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.

These guidelines cover the main Kubernetes blog and the Kubernetes contributor blog. All blog content must also adhere to the overall policy in the content guide. Before you begin Make sure you are familiar with the introduction sections of contributing to Kubernetes blogs, not just to learn about the two official blogs and the differences between them, but also to get an overview of the process. Original content The Kubernetes project accepts original content only, in English.

This site uses Hugo. In Hugo, content organization is a core concept. Note:Hugo Tip: Start Hugo with hugo server --navigateToChanged for content edit-sessions. Page Lists Page Order The documentation side menu, the documentation page browser etc. are listed using Hugo's default sort order, which sorts by weight (from 1), date (newest first), and finally by the link title. Given that, if you want to move a page or a section up, set a weight in the page's front matter:

Resource Types Preference Preference Preference stores elements of KubeRC configuration file FieldDescription apiVersionstringkubectl.config.k8s.io/v1alpha1 kindstringPreference overrides [Required] []CommandDefaults overrides allows changing default flag values of commands. This is especially useful, when user doesn't want to explicitly set flags each time. aliases [Required] []AliasOverride aliases allow defining command aliases for existing kubectl commands, with optional default flag values. If the alias name collides with a built-in command, built-in command always takes precedence. Flag overrides defined in the overrides section do NOT apply to aliases for the same command.

This page shows how to perform a rollback on a DaemonSet. 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. If you do not already have a cluster, you can create one by using minikube or you can use one of these Kubernetes playgrounds:
