Microsoft Azure Container Networking

Overview
This repository contains container networking services and plugins for Linux and Windows containers running on Azure:
- Azure CNI network and IPAM plugins for Kubernetes.
- Azure NPM - Kubernetes Network Policy Manager (Linux and (preview) Windows Server 2022)
The azure-vnet network plugins connect containers to your Azure VNET, to take advantage of Azure SDN capabilities. The azure-vnet-ipam IPAM plugins provide address management functionality for container IP addresses allocated from Azure VNET address space.
The following environments are supported:
- Microsoft Azure: Available in all Azure regions.
Plugins are offered as part of Azure Kubernetes Service (AKS), as well as for individual Azure IaaS VMs. For Kubernetes clusters created by aks-engine, the deployment and configuration of both plugins on both Linux and Windows nodes is automatic and default.
The next generation of Azure CNI Plugin is powered by Cilium. Learn more at Azure CNI Powered By Cilium
