Kubernetes versions supported by ACK - Container Service for Kubernetes

Container Service for Kubernetes (ACK) provides a variety of cluster types such as ACK managed clusters, ACK dedicated clusters, ACK Serverless clusters, and ACK Edge clusters. As new Kubernetes versions are released, the list of Kubernetes versions supported by ACK changes. New Kubernetes versions are added to the list and outdated Kubernetes versions are discontinued. The Kubernetes versions supported by an ACK cluster vary based on the cluster type. This topic describes the Kubernetes versions supported by multiple types of ACK clusters.
