Network Policy

Last updated: 2024-02-01 10:16:11

    Overview

    Add-on description

    Network Policy is a resource provided by Kubernetes for defining pod-based network isolation policies. It describes whether a group of pods can communicate with other groups of pods and other network entities. This add-on provides a controller for implementing resources of this type. You can use this add-on if you want to control the network traffic of specific applications at the IP address or port layer (layer 3 or layer 4 of OSI).
