Beispiel-Dokumentation: ExternalName Service Discovery

Ziel

Einen stabilen internen Service-Namen für ein externes DNS-Ziel verwenden.

01 / 05

Was gemacht wird

Ein ExternalName-Service zeigt auf kubernetes.io. Ein Client-Pod kann den internen Namen docs-service auflösen.

02 / 05

Typische Kommandos

bash
kubectl apply -f manifests/
kubectl get svc -n externalname-lab
kubectl exec -n externalname-lab deploy/dns-client -- nslookup docs-service
03 / 05

Erfolg prüfen

  • Der Service hat Typ ExternalName.
  • externalName zeigt auf kubernetes.io.
  • Der Client kann docs-service per DNS auflösen.
04 / 05

Typische Fehler

  • ExternalName wird wie ein ClusterIP-Service erwartet.
  • Anwendungen erwarten IPs statt CNAME-Auflösung.
  • Netzwerk- oder DNS-Policies blockieren die externe Auflösung.
