Commencez avec une CloudFront distribution de base à l'aide de la CLI

L’exemple de code suivant illustre comment :

Création d'un compartiment Amazon S3 pour le stockage de contenu
Chargez un exemple de contenu dans le compartiment S3
Créez un contrôle d'accès à l'origine (OAC) pour un accès S3 sécurisé
Création d'une CloudFront distribution avec S3 comme origine
Mettre à jour la politique du compartiment S3 pour autoriser CloudFront l'accès
Attendre le déploiement de la distribution et tester l'accès au contenu
Nettoyez les ressources, y compris la distribution, l'OAC et le compartiment S3

Bash
