Kube-DNS is a DNS service that runs within a Kubernetes cluster, providing name resolution for services and pods. It allows applications to discover and communicate with each other using DNS names instead of IP addresses.
Key features of Kube-DNS include:
- Service Discovery: Automatically resolves service names to their corresponding IP addresses, enabling seamless communication between services.
- Cluster DNS: Provides a DNS server that responds to queries for services and pods within the cluster.
- Custom DNS Records: Allows users to create custom DNS records for their applications if needed.
Kube-DNS is typically deployed as a set of pods in the cluster and is an essential component for enabling service discovery in Kubernetes environments.
