Container Service for Kubernetes:Release notes for Terway Edge network plug-in

Introduction

Terway Edge applies distinct network solutions for different node pool types.

• In the cloud node pool, Terway adopts a cloud-native network solution and configures the container network by using elastic network interfaces (ENIs). An ENI is a virtual network interface controller (NIC) provided by Alibaba Cloud. An ENI assigns IP addresses within a virtual private cloud (VPC) to pods. You do not need to specify a CIDR block for the pods.

• In the edge node pool, a vSwitch CIDR block must be specified for pods. The container will acquire IP addresses from this pod CIDR block. Additionally, advertising routes to the vSwitche through Border Gateway Protocol (BGP) is supported in the container.

Limits

• The container network plug-in must be installed during cluster creation and cannot be modified thereafter.

• Only ACK Edge clusters that run Kubernetes 1.28 or later are supported. For more information about how to use the Terway Edge network plug-in, see Use Terway Edge.
