Schritt 1: Herunterladen der AWS CloudFormation Vorlage

Sie können -AWS CloudFormationVorlagen verwenden, um Portfolios und Produkte zu konfigurieren und bereitzustellen. Bei diesen Vorlagen handelt es sich um Textdateien, die in JSON oder YAML formatiert werden können und die Ressourcen beschreiben, die Sie bereitstellen möchten. Weitere Informationen finden Sie unter Vorlagenformate im AWS CloudFormation-Benutzerhandbuch. Sie können den AWS CloudFormation Editor oder einen Texteditor Ihrer Wahl verwenden, um Vorlagen zu erstellen und zu speichern. In diesem Tutorial stellen wir eine einfache Vorlage bereit, damit Sie loslegen können. Die Vorlage startet eine einzelne Linux-Instance, die für den SSH-Zugriff konfiguriert ist.

Herunterladen der Vorlage

Die für dieses Tutorial bereitgestellte Beispielvorlage, development-environment.template, ist unter https://awsdocs.s3.amazonaws.com/servicecatalog/development-environment.template verfügbar.

Der Text der Beispielvorlage lautet wie folgt:

  "Description" : "AWS Service Catalog sample template. Creates an Amazon EC2 instance 
                    running the Amazon Linux AMI. The AMI is chosen based on the region 
                    in which the stack is run. This example creates an EC2 security 
                    group for the instance to give you SSH access. **WARNING** This 
                    template creates an Amazon EC2 instance. You will be billed for the
