Static Pods are managed directly by the kubelet daemon on a specific node, without the API server observing them. Unlike Pods that are managed by the control plane (for example, a Deployment); instead, the kubelet watches each static Pod (and restarts it if it fails). Static Pods are always bound to one Kubelet on a specific node. The kubelet automatically tries to create a mirror Pod on the Kubernetes API server for each static Pod.

Caution:kubeadm alpha provides a preview of a set of features made available for gathering feedback from the community. Please try it out and give us feedback! Currently there are no experimental commands under kubeadm alpha. What's next kubeadm init to bootstrap a Kubernetes control-plane node kubeadm join to connect a node to the cluster kubeadm reset to revert any changes made to this host by kubeadm init or kubeadm join

kubeadm init phase enables you to invoke atomic steps of the bootstrap 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 init phase is consistent with the kubeadm init workflow, and behind the scene both use the same code. kubeadm init phase preflight Using this command you can execute preflight checks on a control-plane node.

To report a security issue, please follow the Kubernetes security disclosure process. Work on Kubernetes code and public issues are tracked using GitHub Issues. Official list of known CVEs (security vulnerabilities) that have been announced by the Security Response Committee CVE-related GitHub issues Security-related announcements are sent to the kubernetes-security-announce@googlegroups.com mailing list.

This page shows how to write and read a Container termination message. Termination messages provide a way for containers to write information about fatal events to a location where it can be easily retrieved and surfaced by tools like dashboards and monitoring software. In most cases, information that you put in a termination message should also be written to the general Kubernetes logs. Before you begin You need to have a Kubernetes cluster, and the kubectl command-line tool must be configured to communicate with your cluster.

Extend kubectl by creating and installing kubectl plugins.

This page shows how to create a Kubernetes Service object that exposes an external IP address. Before you begin Install kubectl. Use a cloud provider like Google Kubernetes Engine or Amazon Web Services to create a Kubernetes cluster. This tutorial creates an external load balancer, which requires a cloud provider. Configure kubectl to communicate with your Kubernetes API server. For instructions, see the documentation for your cloud provider. Objectives Run five instances of a Hello World application.

FEATURE STATE: Kubernetes v1.34 [beta] This page provides an overview of MutatingAdmissionPolicies. MutatingAdmissionPolicies allow you change what happens when someone writes a change to the Kubernetes API. If you want to use declarative policies just to prevent a particular kind of change to resources (for example: protecting platform namespaces from deletion), ValidatingAdmissionPolicy is a simpler and more effective alternative. To use the feature, enable the MutatingAdmissionPolicy feature gate (which is off by default) and set --runtime-config=admissionregistration.

Objectives Scale an existing app manually using kubectl. Scaling an application You can create from the start a Deployment with multiple instances using the --replicas parameter for the kubectl create deployment command. Previously we created a Deployment, and then exposed it publicly via a Service. The Deployment created only one Pod for running our application. When traffic increases, we will need to scale the application to keep up with user demand.
