AWS Cloudformation：YAML：密钥：预期名称 <block end>，但发现“？”值：“PublicSubnet2”

问题描述 投票：0回答：1

问题

YAML 格式错误，无法确定此 YAML 格式在线工具中缺少哪些内容需要纠正：https://www.anyjson.in/yaml-formatter 检查我的 YAML 脚本。

YAML 修复格式的努力

我尝试过值：公共子网2；值：公共子网2；值：“公共子网2”。在线 YAML 格式化程序中都出现相同的格式错误

YAML 错误

下面的 YAML 脚本中给出了以下 YAML 语法错误。我已经改了好几次了，还是无法解决格式yaml错误。

我尝试过值：公共子网2；值：公共子网2；值：“公共子网2”。现在不知道下一步要纠正第 82/83 行的 YAML 格式，根据下面的错误（下一个）

Line 83: while parsing a block collection in "<unicode string>", line 82, column 9: - Key: Name ^ (line: 82) expected <block end>, but found '?' in "<unicode string>", line 83, column 9: Value: 'PublicSubnet2' ^ (line: 83)

YAML 脚本

线路82/83

       - Key: Name

        Value: 'PublicSubnet2'

在此块中可以找到键/值 YAML 脚本的完整范围：

  Subnet2:
    Type: AWS::EC2::Subnet
    Properties:
      VpcId: Ref VPC
      CidrBlock: 10.0.30.0/24
      MapPublicIpOnLaunch: true
      Tags:
        - Key: Name
        Value: 'PublicSubnet2'

您的 

Value
缩进错误，并且 
Ref
拼写错误。应该是：

  Subnet2:
    Type: AWS::EC2::Subnet
    Properties:
      VpcId: !Ref VPC
      CidrBlock: 10.0.30.0/24
      MapPublicIpOnLaunch: true
      Tags:
        - Key: Name
          Value: 'PublicSubnet2'

您不必检查模板的其余部分是否存在类似问题。
