Namespaces can be labeled to enforce the Pod Security Standards. The three policies privileged, baseline and restricted broadly cover the security spectrum and are implemented by the Pod Security admission controller. Before you begin Pod Security Admission was available by default in Kubernetes v1.23, as a beta. From version 1.25 onwards, Pod Security Admission is generally available. To check the version, enter kubectl version. Requiring the baseline Pod Security Standard with namespace labels This manifest defines a Namespace my-baseline-namespace that:

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.

This page shows how to delete Pods which are part of a stateful set, and explains the considerations to keep in mind when doing so. Before you begin This is a fairly advanced task and has the potential to violate some of the properties inherent to StatefulSet. Before proceeding, make yourself familiar with the considerations enumerated below. StatefulSet considerations In normal operation of a StatefulSet, there is never a need to force delete a StatefulSet Pod.

Kubernetes provides a built-in admission controller to enforce the Pod Security Standards. You can configure this admission controller to set cluster-wide defaults and exemptions. Before you begin Following an alpha release in Kubernetes v1.22, Pod Security Admission became available by default in Kubernetes v1.23, as a beta. From version 1.25 onwards, Pod Security Admission is generally available. To check the version, enter kubectl version. If you are not running Kubernetes 1.

Provides runtime diagnostics for Kubernetes components, offering insights into component runtime status and configuration flags.

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.

During kubeadm init, kubeadm uploads the ClusterConfiguration object to your cluster in a ConfigMap called kubeadm-config in the kube-system namespace. This configuration is then read during kubeadm join, kubeadm reset and kubeadm upgrade. You can use kubeadm config print to print the default static configuration that kubeadm uses for kubeadm init and kubeadm join. Note:The output of the command is meant to serve as an example. You must manually edit the output of this command to adapt to your setup.

Synopsis Reconciles rules for RBAC role, role binding, cluster role, and cluster role binding objects. Missing objects are created, and the containing namespace is created for namespaced objects, if required. Existing roles are updated to include the permissions in the input objects, and remove extra permissions if --remove-extra-permissions is specified. Existing bindings are updated to include the subjects in the input objects, and remove extra subjects if --remove-extra-subjects is specified.
