kubeadm reset phase enables you to invoke atomic steps of the node reset process. Hence, you can let kubeadm do some of the work and you can fill in the gaps if you wish to apply customization. kubeadm reset phase is consistent with the kubeadm reset workflow, and behind the scene both use the same code. kubeadm reset phase phase Use this command to invoke single phase of the reset workflow

Synopsis Create a role with single rule. kubectl create role NAME --verb=verb --resource=resource.group/subresource [--resource-name=resourcename] [--dry-run=server|client|none] Examples # Create a role named "pod-reader" that allows user to perform "get", "watch" and "list" on pods kubectl create role pod-reader --verb=get --verb=list --verb=watch --resource=pods # Create a role named "pod-reader" with ResourceName specified kubectl create role pod-reader --verb=get --resource=pods --resource-name=readablepod --resource-name=anotherpod # Create a role named "foo" with API Group specified kubectl create role foo --verb=get,list,watch --resource=rs.

This tutorial shows you how to deploy a WordPress site and a MySQL database using Minikube. Both applications use PersistentVolumes and PersistentVolumeClaims to store data. A PersistentVolume (PV) is a piece of storage in the cluster that has been manually provisioned by an administrator, or dynamically provisioned by Kubernetes using a StorageClass. A PersistentVolumeClaim (PVC) is a request for storage by a user that can be fulfilled by a PV.

This tutorial shows you how to run Apache Cassandra on Kubernetes. Cassandra, a database, needs persistent storage to provide data durability (application state). In this example, a custom Cassandra seed provider lets the database discover new Cassandra instances as they join the Cassandra cluster. StatefulSets make it easier to deploy stateful applications into your Kubernetes cluster. For more information on the features used in this tutorial, see StatefulSet. Note:Cassandra and Kubernetes both use the term node to mean a member of a cluster.

This section provides reference information for the Kubernetes API. The REST API is the fundamental fabric of Kubernetes. All operations and communications between components, and external user commands are REST API calls that the API Server handles. Consequently, everything in the Kubernetes platform is treated as an API object and has a corresponding entry in the API. The Kubernetes API reference lists the API for Kubernetes version v1.30. For general background information, read The Kubernetes API.

Kubernetes certificate and trust bundle APIs enable automation of X.509 credential provisioning by providing a programmatic interface for clients of the Kubernetes API to request and obtain X.509 certificates from a Certificate Authority (CA). There is also experimental (alpha) support for distributing trust bundles. Certificate signing requests FEATURE STATE: Kubernetes v1.19 [stable] A CertificateSigningRequest (CSR) resource is used to request that a certificate be signed by a denoted signer, after which the request may be approved or denied before finally being signed.

Synopsis Deny a certificate signing request. kubectl certificate deny allows a cluster admin to deny a certificate signing request (CSR). This action tells a certificate signing controller to not to issue a certificate to the requester. kubectl certificate deny (-f FILENAME | NAME) Examples # Deny CSR 'csr-sqgzp' kubectl certificate deny csr-sqgzp Options --allow-missing-template-keys     Default: true If true, ignore any errors in templates when a field or map key is missing in the template.

kubeadm upgrade is a user-friendly command that wraps complex upgrading logic behind one command, with support for both planning an upgrade and actually performing it. kubeadm upgrade guidance The steps for performing an upgrade using kubeadm are outlined in this document. For older versions of kubeadm, please refer to older documentation sets of the Kubernetes website. You can use kubeadm upgrade diff to see the changes that would be applied to static pod manifests.
