Details
Dynamic Name System (DNS) provides a way to translate hostnames to IP addresses for systems located anywhere on your network or the Internet. CoreDNS provides the same DNS service within your Kubernetes cluster to ensure that all deployments on your Kubernetes cluster have a reliable communication mechanism between the pods and services it uses. CoreDNS resolves requests for hostnames to IP addresses within the Oracle Cloud Native Environment cluster.
