Synopsis Approve a certificate signing request. kubectl certificate approve allows a cluster admin to approve a certificate signing request (CSR). This action tells a certificate signing controller to issue a certificate to the requester with the attributes requested in the CSR. SECURITY NOTICE: Depending on the requested attributes, the issued certificate can potentially grant a requester access to cluster resources or to authenticate as a requested identity. Before approving a CSR, ensure you understand what the signed certificate can do.

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 page serves as a reference for the audit annotations of the kubernetes.io namespace. These annotations apply to Event object from API group audit.k8s.io. Note:The following annotations are not used within the Kubernetes API. When you enable auditing in your cluster, audit event data is written using Event from API group audit.k8s.io. The annotations apply to audit events. Audit events are different from objects in the Event API (API group events.

This tutorial shows you how to run a sample app on Kubernetes using minikube. The tutorial provides a container image that uses NGINX to echo back all the requests. Objectives Deploy a sample application to minikube. Run the app. View application logs. Before you begin This tutorial assumes that you have already set up minikube. See Step 1 in minikube start for installation instructions. Note:Only execute the instructions in Step 1, Installation.

Kubernetes auditing provides a security-relevant, chronological set of records documenting the sequence of actions in a cluster. The cluster audits the activities generated by users, by applications that use the Kubernetes API, and by the control plane itself. Auditing allows cluster administrators to answer the following questions: what happened? when did it happen? who initiated it? on what did it happen? where was it observed? from where was it initiated?

This page shows how to configure a Key Management Service (KMS) provider and plugin to enable secret data encryption. In Kubernetes 1.31 there are two versions of KMS at-rest encryption. You should use KMS v2 if feasible because KMS v1 is deprecated (since Kubernetes v1.28) and disabled by default (since Kubernetes v1.29). KMS v2 offers significantly better performance characteristics than KMS v1. Caution:This documentation is for the generally available implementation of KMS v2 (and for the deprecated version 1 implementation).

FEATURE STATE: Kubernetes v1.31 [alpha] (enabled by default: false) This page shows how to configure a pod using image volumes. This allows you to mount content from OCI registries inside containers. 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.
