This document catalogs the communication paths between the API server and the Kubernetes cluster. The intent is to allow users to customize their installation to harden the network configuration such that the cluster can be run on an untrusted network (or on fully public IPs on a cloud provider). Node to Control Plane Kubernetes has a "hub-and-spoke" API pattern. All API usage from nodes (or the pods they run) terminates at the API server.

You can visualize and manage Kubernetes objects with more tools than kubectl and the dashboard. A common set of labels allows tools to work interoperably, describing objects in a common manner that all tools can understand. In addition to supporting tooling, the recommended labels describe applications in a way that can be queried. The metadata is organized around the concept of an application. Kubernetes is not a platform as a service (PaaS) and doesn't have or enforce a formal notion of an application.

FEATURE STATE: Kubernetes v1.33 [stable] (enabled by default: true) Sidecar containers are the secondary containers that run along with the main application container within the same Pod. These containers are used to enhance or to extend the functionality of the primary app container by providing additional services, or functionality such as logging, monitoring, security, or data synchronization, without directly altering the primary application code. Typically, you only have one app container in a Pod.

FEATURE STATE: Kubernetes v1.23 [stable] Your Kubernetes cluster includes dual-stack networking, which means that cluster networking lets you use either address family. In a cluster, the control plane can assign both an IPv4 address and an IPv6 address to a single Pod or a Service. Before you begin You need to have installed the kubeadm tool, following the steps from Installing kubeadm. For each server that you want to use as a node, make sure it allows IPv6 forwarding.

This website contains documentation for the current version of Kubernetes and the four previous versions of Kubernetes. The availability of documentation for a Kubernetes version is separate from whether that release is currently supported. Read Support period to learn about which versions of Kubernetes are officially supported, and for how long.
