无效的模板属性 [ElasticacheCluster]

如何解决无效的模板属性 [ElasticacheCluster]

我遇到了标题中提到的错误，但我不知道如何修复它。 错误在 ElasticacheCluster 部分。 我试图以多种方式修改它，这就是为什么有一些注释的代码行但我没有删除它们可能有助于故障排除。 这是我的代码如下：

    #### Creating Elasticache ####

  ElasticacheSecurityGroup:
    Type: 'AWS::EC2::SecurityGroup'
    Properties:
      GroupDescription: Elasticache Security Group
      VpcId: !Ref PubPrivateVPC
      SecurityGroupIngress:
        - IpProtocol: tcp
          FromPort: '11211'
          ToPort: '11211'
          CidrIp: 0.0.0.0/0
      Tags:
        -
          Key: "Name"
          Value: !Join [_,[!Ref 'AWS::StackName',ElasiCache-SG]]
#          SourceSecurityGroupName: !Ref InstanceSecurityGroup

  CachesubnetGroup:
    Type: 'AWS::ElastiCache::subnetGroup'
    Properties:
      Description: cache
      subnetIds:
        - !Ref Privatesubnet1
        - !Ref Privatesubnet2
        - !Ref Privatesubnet3

ElasticacheCluster:
  Type: AWS::ElastiCache::CacheCluster
  Properties:    
    Engine: memcached
    EngineVersion: 1.6.6
    CacheNodeType: cache.t2.micro
    CachesubnetGroupName: !Ref CachesubnetGroup
    NumCacheNodes: '1'
#    VpcId: !Ref PubPrivateVPC
    VpcSecurityGroupIds: !Ref ElasticacheSecurityGroup
#      - !GetAtt 
#        - ElasticacheSecurityGroup
#        - GroupId

解决方法

您的集群资源没有缩进。

这应该有效：

  ElasticacheSecurityGroup:
    Type: 'AWS::EC2::SecurityGroup'
    Properties:
      GroupDescription: Elasticache Security Group
      VpcId: !Ref PubPrivateVPC
      SecurityGroupIngress:
        - IpProtocol: tcp
          FromPort: '11211'
          ToPort: '11211'
          CidrIp: 0.0.0.0/0
      Tags:
        -
          Key: "Name"
          Value: !Join [_,[!Ref 'AWS::StackName',ElasiCache-SG]]
#          SourceSecurityGroupName: !Ref InstanceSecurityGroup

  CacheSubnetGroup:
    Type: 'AWS::ElastiCache::SubnetGroup'
    Properties:
      Description: cache
      SubnetIds:
        - !Ref PrivateSubnet1
        - !Ref PrivateSubnet2
        - !Ref PrivateSubnet3

  ElasticacheCluster:
    Type: AWS::ElastiCache::CacheCluster
    Properties:    
      Engine: memcached
      EngineVersion: 1.6.6
      CacheNodeType: cache.t2.micro
      CacheSubnetGroupName: !Ref CacheSubnetGroup
      NumCacheNodes: '1'
  #    VpcId: !Ref PubPrivateVPC
      VpcSecurityGroupIds: 
        - !Ref ElasticacheSecurityGroup
  #      - !GetAtt 
  #        - ElasticacheSecurityGroup
  #        - GroupId
