Container Service for Kubernetes:Expand an edge cluster

Last Updated:Dec 05, 2023

You can expand an ACK Edge cluster in the Container Service for Kubernetes (ACK) console. You do not need to purchase edge nodes and add these nodes to the cluster. You can directly purchase edge nodes on the cluster expansion page. The purchased nodes are automatically added to the cluster. This topic describes how to expand an ACK Edge cluster by adding edge nodes of Edge Node Service (ENS) or by adding Elastic Compute Service (ECS) nodes.
