Beispiel-Dokumentation: Multi Container Pod

Ziel

Pod-Grenzen anhand zweier Container mit gemeinsamem Netzwerk verstehen.

01 / 05

Was gemacht wird

Ein Webcontainer stellt NGINX bereit. Ein Helper-Container im selben Pod prüft den Webcontainer über 127.0.0.1.

02 / 05

Typische Kommandos

bash
kubectl apply -f manifests/
kubectl logs -n multi-lab pod/multi-container-demo -c helper --tail=20
kubectl port-forward -n multi-lab pod/multi-container-demo 8080:8080
03 / 05

Erfolg prüfen

  • Beide Container laufen im Pod.
  • Der Helper erreicht den Webcontainer über localhost.
  • Port-Forwarding auf den Pod zeigt den Webinhalt.
04 / 05

Typische Fehler

  • Container werden fälschlich als getrennte Hosts betrachtet.
  • Gemeinsames Netzwerk wird mit gemeinsamem Dateisystem verwechselt.
  • Ein Container-Crash beeinflusst den gesamten Pod-Lifecycle.
