amazon-web-services - AWS 上的 CloudFormation 模板错误

Question

在解决我的 AWS 模板上的这些错误时遇到问题。

这是我的错误:

WobblelandSecurityGroup CREATE_FAILED 属性 GroupName 的值必须为字符串类型

PrivateSubnet CREATE_FAILED 资源 PrivateSubnet 的属性验证失败，消息为:#/AvailabilityZone:预期类型:字符串，找到:JSONArray

InternetGateway CREATE_FAILED 资源 InternetGateway 的属性验证失败，并显示消息:#:不允许使用无关 key [KeyName]

这是我的模板:

Answer 1

您遇到了三个不同的错误。

---

对于第一个:

WobblelandSecurityGroup CREATE_FAILED Value of property GroupName must be of type String

这是因为 GroupName 属性的类型不正确；我想你想要:

  GroupName: !Join
    - "-"
    - - Wobbleland-security-group
      - dev

---

对于第二个:

PrivateSubnet CREATE_FAILED Properties validation failed for resource PrivateSubnet with message: #/AvailabilityZone: expected type: String, found: JSONArray

这是因为 AvailabilityZone 属性的类型不正确；我想你想要:

AvailabilityZone: !Select [ 0, !GetAZs ]

---

第三个:

InternetGateway CREATE_FAILED Properties validation failed for resource InternetGateway with message: #: extraneous key [KeyName] is not permitted

这是因为 KeyName 不是该资源的有效属性。您可以从文档中找到更多关于哪些 key 资源支持的信息；在这种情况下，this page .
