Helm introduction
Das Dokument beschreibt die Konfiguration eines Kubernetes-Deployments für eine Anwendung namens 'helloworld-dev', das zwei Replikate und spezifische Umgebungsvariablen umfasst. Außerdem werden Ingress-Regeln und TLS-Konfigurationen für den Zugriff auf die Anwendung behandelt. Des Weiteren werden Hinweise zur Verwendung von Helm zur Bereitstellung und Verwaltung von Kubernetes-Ressourcen gegeben.
