A WebHook is an HTTP callback: an HTTP POST that occurs when something happens; a simple event-notification via HTTP POST. A web application implementing WebHooks will POST a message to a URL when certain things happen. When specified, mode Webhook causes Kubernetes to query an outside REST service when determining user privileges. Configuration File Format Mode Webhook requires a file for HTTP configuration, specify by the --authorization-webhook-config-file=SOME_FILENAME flag. The configuration file uses the kubeconfig file format.

The tables below enumerate the configuration parameters on PodSecurityPolicy objects, whether the field mutates and/or validates pods, and how the configuration values map to the Pod Security Standards. For each applicable parameter, the allowed values for the Baseline and Restricted profiles are listed. Anything outside the allowed values for those profiles would fall under the Privileged profile. "No opinion" means all values are allowed under all Pod Security Standards.

Overview Package v1beta3 defines the v1beta3 version of the kubeadm configuration file format. This version improves on the v1beta2 format by fixing some minor issues and adding a few new fields. A list of changes since v1beta2: The deprecated "ClusterConfiguration.useHyperKubeImage" field has been removed. Kubeadm no longer supports the hyperkube image. The "ClusterConfiguration.dns.type" field has been removed since CoreDNS is the only supported DNS server type by kubeadm. Include "datapolicy" tags on the fields that hold secrets.

Synopsis Update existing container image(s) of resources. Possible resources include (case insensitive): pod (po), replicationcontroller (rc), deployment (deploy), daemonset (ds), statefulset (sts), cronjob (cj), replicaset (rs) kubectl set image (-f FILENAME | TYPE NAME) CONTAINER_NAME_1=CONTAINER_IMAGE_1 ...

Mechanisms for accessing metrics at node, volume, pod and container level, as seen by the kubelet.

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.
