Existe-t-il un exemple de modèle Cloudformation avec plusieurs CacheBehaviors définis ?

Question

Comment puis-je l'utiliser dans un modèle ? Je n'ai trouvé aucun exemple : * https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-properties-cloudfront-distribution-distributionconfig.html#cfn-cloudfront-distribution-distributionconfig-cachebehaviors * https://docs.amazonaws.cn/en_us/AWSCloudFormation/latest/UserGuide/aws-properties-cloudfront-distribution-cachebehavior.html

J'ai défini un DefaultCacheBehavior et je veux maintenant ajouter des comportements supplémentaires.

J'ai essayé mais j'obtiens une erreur :

Answer 2

Il y a un exemple de plusieurs CacheBehaviors aquí .

Je pense que votre problème est la formulation d'un tableau d'objets dans YAML. Voir la question suivante :
