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"
