Question

我编写了以下模板，以根据用户输入选择环境。但是我收到错误消息，因为“调用CreateStack操作时发生错误（ValidationError）：模板格式错误：[/ Resources / Type]资源定义格式错误”。请指导我需要更改的内容以及语法是否采用正确的格式

      Parameters:
          EnvironmentValue:

             Description: 'Please select an Environment'
             Type: String
      Mappings:
          Environment:

                Securitygroups: 'sg-xxxx,sg-xxxx'

                   VolumeSize: 100
                   VolumeType: gp2
               VPCOptions: !FindInMap [Environment, !Ref 'EnvironmentValue', VPC]
               SubnetIds: !FindInMap [Environment, !Ref 'EnvironmentValue', Subnets]
               Securitygroups: !FindInMap [Environment, !Ref 'EnvironmentValue', Securitygroups]

                      AutomatedSnapshotStartHour: '0'
          Type: 'AWS::IAM::Policy'
              Properties: 
                  PolicyDocument: YAML
                  PolicyName: prodtest

当用户提供输入作为Prod时，应在Cloudformation中创建Prod的堆栈

我在这里看到一些问题：

1-您尚未命名资源。 2-缩进看起来不正确，这对于yaml很重要 3-我认为您的Elasticsearch域类型不正确。你有

Type: 'AWS::Es:Domain'

但我认为应该是

Type: AWS::Elasticsearch::Domain

以您的域为例，我认为应该更像是：

ElasticsearchDomain:
    Type: AWS::Elasticsearch::Domain
    Properties:
        DomainName: EPD34
        ElasticsearchVersion: 6.5
        ElasticsearchClusterConfig:
            DedicatedMasterEnabled: 'true'
            InstanceCount: '2'
            ZoneAwarenessEnabled: 'true'
            InstanceType: r4.xlarge.elasticsearch
            DedicatedMasterType: r4.xlarge.elasticsearch
            DedicatedMasterCount: '2'
        EBSOptions:
            EBSEnabled: true
            Iops: 0
            VolumeSize: 100
            VolumeType: gp2
        VPCOptions: !FindInMap [Environment, !Ref 'EnvironmentValue', VPC]
        SubnetIds: !FindInMap [Environment, !Ref 'EnvironmentValue', Subnets]
        Securitygroups: !FindInMap [Environment, !Ref 'EnvironmentValue', Securitygroups]
        SnapshotOptions:
            AutomatedSnapshotStartHour: '0'

这里可能还缺少其他问题，但是这里肯定有语法错误

Answer 2

类型标记应为'AWS :: Elasticsearch :: Domain'，并且根据yaml声明存在多种格式错误。属性应与类型处于同一级别。然后，VPCOptions应该具有以下两个属性。对于给定的示例，模板应如下所示

var data = await GetCovidData("https://covid19.mathdro.id/api");

Console.WriteLine(data.Confirmed.Value);
Console.WriteLine(data.Confirmed.Detail);
Console.WriteLine(data.Recovered.Value);

AWS cloudformation elasticsearch堆栈
