CoreDNS is a DNS-based service discovery component, which can be installed in ACS clusters to conduct service discovery. The topic introduces CoreDNS and describes the usage notes and release notes for CoreDNS.
Introduction
CoreDNS provides DNS resolution capabilities within Kubernetes clusters. ACK maintains a mapping between CoreDNS versions and Kubernetes versions. When you create or update a Kubernetes cluster, the CoreDNS version that is installed or updated depends on the Kubernetes version of the cluster. For more information about the mapping, see CoreDNS version in Kubernetes.
