# Kubernetes Services and DNS

## Short answer
A Service exposes a network application running behind Pods under one stable endpoint. Cluster DNS gives Services consistent names so clients need not track Pod IPs. [S1][S2]

## Points
- Services let you keep unfamiliar discovery logic out of the app. [S1]
- Kubernetes creates DNS records for Services and Pods. [S2]
- kubelet configures Pod DNS so containers can look up Services by name. [S2]
- Services defined in the cluster get DNS names. [S2]

## Claims
- id: C1
  claim: A Service exposes a network application.
  source: S1
  evidence: "a Service is a method for exposing a network application"
- id: C2
  claim: Services hide unfamiliar service discovery from the app.
  source: S1
  evidence: "you don't need to modify your existing application to use an unfamiliar service discovery mechanism"
- id: C3
  claim: Kubernetes creates DNS records for Services and Pods.
  source: S2
  evidence: "Kubernetes creates DNS records for Services and Pods"
- id: C4
  claim: Cluster Services are assigned DNS names.
  source: S2
  evidence: "Services defined in the cluster are assigned DNS names"
