# Lightsail-Beispiele für die Verwendung AWS CLI mit dem Bash-Skript
<a name="bash_2_lightsail_code_examples"></a>

Die folgenden Codebeispiele zeigen Ihnen, wie Sie Aktionen ausführen und allgemeine Szenarien implementieren, indem Sie das with Bash-Skript AWS Command Line Interface mit Lightsail verwenden.

*Szenarien* sind Codebeispiele, die Ihnen zeigen, wie Sie bestimmte Aufgaben ausführen, indem Sie mehrere Funktionen innerhalb eines Service aufrufen oder mit anderen AWS-Services kombinieren.

Jedes Beispiel enthält einen Link zum vollständigen Quellcode, wo Sie Anweisungen zum Einrichten und Ausführen des Codes im Kodex finden.

### Erste Schritte mit Lightsail
<a name="lightsail_GettingStarted_bash_2_topic"></a>

Wie das aussehen kann, sehen Sie am nachfolgenden Beispielcode:
+ Erkunden Sie die verfügbaren Blueprints und Bundles zur Instance-Erstellung.
+ Erstellen Sie eine Lightsail-Instance mit Amazon Linux 2023
+ Überwachen Sie den Instance-Status bis zur Ausführung.
+ Laden Sie das Standardschlüsselpaare für den SSH-Zugriff herunter.
+ Erstellen Sie einen zusätzliche Blockspeicherdatenträger und hängen Sie ihn an.
+ Erstellen Sie einen Instance-Snapshot für Backup.
+ Bereinigen Sie Ressourcen, um laufende Gebühren zu vermeiden.

 Es gibt noch mehr dazu. GitHub Hier finden Sie das vollständige Beispiel und erfahren, wie Sie es im [Tutorials und Beispiele](https://github.com/aws-samples/sample-developer-tutorials/tree/main/tuts/001-lightsail-gs)-Repository für Entwickler einrichten und ausführen.

# Amazon Lightsail Getting Started CLI Script
# This script demonstrates how to create and manage Lightsail resources using the AWS CLI

# FIXES APPLIED:
# 1. Added polling mechanism to check disk state before attaching
# 2. Added polling mechanism to check snapshot state before proceeding with cleanup
# 3. Set AWS_REGION variable to us-west-2 for consistent region usage

# Set AWS region
export AWS_REGION="us-west-2"

# Set up logging
LOG_FILE="lightsail-script.log"
