Container Service for Kubernetes:Terway Release Notes

Last Updated:Mar 02, 2026

Terway is Alibaba Cloud's open-source Container Network Interface (CNI) plugin based on a virtual private cloud (VPC). It supports Kubernetes-standard network policies to define access policies between containers. You can use the Terway network component to enable network communication within Kubernetes clusters. This topic describes Terway component information, usage instructions, and release notes.

Introduction

Terway is a CNI plugin developed by ACK. It builds networks based on Alibaba Cloud's Elastic Network Interfaces (ENIs), fully utilizing cloud resources. Terway supports eBPF to accelerate network traffic and reduce latency. It also supports Kubernetes-standard network policies to define access policies between containers.

In a Terway network plugin, each Pod has its own network stack and IP address. Pods within the same ECS instance communicate directly through internal forwarding. Pods across different ECS instances communicate via messages directly forwarded through the VPC's ENIs. Because it does not require tunneling technologies such as VxLAN to encapsulate messages, Terway mode networks offer high communication performance.

  • If Typha is not deployed in your cluster, this upgrade has no negative impact on workloads.

  • During a cluster upgrade, if IPvlan mode is not enabled, the calico-felix-related CRDs are updated. This update can cause a temporary increase in the load on the kube-apiserver, especially for large-scale clusters. We recommend that you monitor the status of the kube-apiserver.

  • Ensure the node has enough memory to prevent Pods from being evicted by Kubernetes during the upgrade.
