How Does Azure CNI Provide Advanced Networking for AKS, AKS Engine, and Docker?
Learn which container solutions, including Azure Kubernetes Service (AKS), AKS Engine, and Docker, use the Azure Virtual Network CNI plugin for advanced networking capabilities. Get a clear explanation relevant for the AZ-500 exam on how this integration provides direct VNet connectivity.
Question
The Azure Virtual Network Container Network Interface (CNI) enables advanced networking for the following container solutions. (choose the best answer)
A. Azure Kubernetes Service (AKS)
B. AKS Engine
C. Docker containers
D. All the above
Answer
D. All the above
Explanation
Azure Virtual Network CNI supports AKS, AKS Engine, as well as Docker.
The statement is correct because the Azure Virtual Network Container Network Interface (CNI) plugin is a versatile networking solution designed to provide native virtual network connectivity to containers across different Azure environments. Its primary function is to assign an IP address from the virtual network’s subnet directly to a container or pod, allowing it to communicate with other network resources as a first-class citizen on the VNet.
This direct integration enables “advanced networking” features like applying Network Security Groups (NSGs), User-Defined Routes (UDRs), and using VNet service endpoints directly with container workloads. The plugin supports all the listed solutions:
- Azure Kubernetes Service (AKS): This is the most common use case. When you create an AKS cluster and choose “Azure CNI” as the network plugin, every pod receives an IP address directly from the node’s subnet. This facilitates seamless communication between pods and other Azure services.
- AKS Engine: This is the open-source project behind AKS that allows you to provision self-managed Kubernetes clusters on Azure. AKS Engine also supports configuring the cluster to use the Azure CNI plugin, providing the same level of VNet integration as the managed AKS offering.
- Docker containers: The Azure CNI plugin can be installed and used directly on an Azure virtual machine running Docker. This allows individual Docker containers, running outside of a Kubernetes orchestrator, to acquire their own IP addresses from the VM’s virtual network, bypassing the default Docker bridge networking.
