## What it is
The Kubernetes DNS (kube-dns) project provides cluster-internal DNS resolution for Kubernetes services and pods. It ships containerized components including kube-dns, dnsmasq, and a sidecar that together serve DNS queries inside a Kubernetes cluster.

## Use cases
- resolve kubernetes service names inside the cluster
- set up cluster dns for a self-managed kubernetes cluster
- replace or configure kube-dns in an existing cluster
- provide dns-based service discovery for pods
- run dns sidecar monitoring for kubernetes dns health

## When to choose
- you operate a Kubernetes cluster and need in-cluster DNS service discovery
- you maintain a legacy cluster still using kube-dns rather than CoreDNS
- you need the bundled dnsmasq and sidecar components for DNS caching and health metrics

## When to avoid
- you are starting a new cluster - CoreDNS is the default Kubernetes DNS provider
- you need general-purpose authoritative or recursive DNS for non-Kubernetes workloads
- you want node-local DNS caching - that moved to kubernetes-sigs/node-local-dns
