How to Continue Dilatation When Container Network Segment Space Is Exhausted (VPC-ENI Mode)

When creating a K8S Cluster CCE with VPC-ENI container network mode, you need to select a VPC subnet as the container subnet. The pods created by the cluster will then be assigned IP addresses from this container subnet.

As the cluster scales up, the IP resources in the container subnet may become depleted. This document outlines how to add new container subnets to a cluster to extend the container network segment.

Usage restrictions

Only support clusters with VPC-ENI container networking mode.
