    Container Service for Kubernetes:Terway release notes

    Last Updated:Dec 20, 2024

    Terway is an open source Container Network Interface (CNI) plug-in that is developed by Alibaba Cloud. Terway works with Virtual Private Cloud (VPC) and allows you to use standard Kubernetes network policies to control how containers communicate with each other. You can use Terway to set up network connectivity within a Kubernetes cluster. The topic introduces Terway and describes the usage notes and release notes for Terway.

    Introduction

    Terway is a CNI plug-in developed by Container Service for Kubernetes (ACK). The plug-in builds networks based on elastic network interfaces (ENIs) of Alibaba Cloud to make full use of cloud resources. Terway supports the use of extended Berkeley Packet Filter (eBPF) to accelerate network traffic and reduce latency. Terway supports standard Kubernetes network policies that define how containers communicate with each other.

    In a cluster that has Terway installed, each pod has a separate network stack and is assigned a separate IP address. Pods on the same Elastic Compute Service (ECS) instance communicate with each other by forwarding packets inside the ECS instance. Pods on different ECS instances communicate with each other through ENIs in the VPC in which the ECS instances are deployed. This improves communication efficiency because no tunneling technologies, such as Virtual Extensible Local Area Network (VXLAN), are required to encapsulate packets.

    • IPv4/IPv6 dual stack is supported.

    • Felix is updated to V3.20.2.

    • CNI is updated from V0.3.0 to V0.3.1.

    • The deployment template of Terway is compatible with Kubernetes 1.22. Terway of this version and later versions are compatible with Kubernetes 1.18 and later versions.

    • The issue that ENI configuration errors occasionally occur in IPVLAN mode is fixed. For more information, see #261.

    • 100Mi memory is added for the Policy container.

    • If Typha is deployed in your cluster to improve the performance of network policies, update Terway to this version. For more information, see Improve the performance of the NetworkPolicy feature for a large ACK cluster in Terway mode.

    • If Typha is not deployed in your cluster, your workloads are not affected.

    • After you disable the IPVLAN mode for a cluster, CRDs that are created for calico-felix are automatically updated when you update the cluster. This may rapidly increase the load on kube-apiserver if the cluster size is large. In this case, we recommend that you pay attention to the load on kube-apiserver.

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