Since release v1.32, we introduced configurable version compatibility and emulation options to Kubernetes control plane components to make upgrades safer by providing more control and increasing the granularity of steps available to cluster administrators. Emulated Version The emulation option is set by the --emulated-version flag of control plane components. It allows the component to emulate the behavior (APIs, features, ...) of an earlier version of Kubernetes. When used, the capabilities available will match the emulated version:

This page explains proxies used with Kubernetes. Proxies There are several different proxies you may encounter when using Kubernetes: The kubectl proxy: runs on a user's desktop or in a pod proxies from a localhost address to the Kubernetes apiserver client to proxy uses HTTP proxy to apiserver uses HTTPS locates apiserver adds authentication headers The apiserver proxy: is a bastion built into the apiserver connects a user outside of the cluster to cluster IPs which otherwise might not be reachable runs in the apiserver processes client to proxy uses HTTPS (or http if apiserver so configured) proxy to target may use HTTP or HTTPS as chosen by proxy using available information can be used to reach a Node, Pod, or Service does load balancing when used to reach a Service The kube proxy:

FEATURE STATE: Kubernetes v1.20 [stable] Kubernetes allow you to limit the number of process IDs (PIDs) that a Pod can use. You can also reserve a number of allocatable PIDs for each node for use by the operating system and daemons (rather than by Pods). Process IDs (PIDs) are a fundamental resource on nodes. It is trivial to hit the task limit without hitting any other resource limits, which can then cause instability to a host machine.
