CloudFormation创建了一个空的DocumentDB。

0

【以下的问题经过翻译处理】 亲爱的各位,

首先我想说我是DocuemntDB的新手。

https://docs.aws.amazon.com/documentdb/latest/developerguide/quick_start_cfn.html的帮助下,我使用CloudFormation创建了一个由3个实例组成的DocumentDB。部署没有出现错误。我尝试使用模板中配置的根用户名和密码进行连接,但没有成功:

E QUERY    [js] Error: Authentication failed. :

然后我尝试不使用任何用户名/密码,我成功连接:

$ mongo --ssl --host XYZ.docdb.amazonaws.com:27017 --sslCAFile rds-combined-ca-bundle.pem 
MongoDB shell version v4.0.28
connecting to: mongodb://XYZ.docdb.amazonaws.com:27017/admin?gssapiServiceName=mongodb
Implicit session: session { "id" : UUID("11254a7a-6610-4db0-a545-3a8bc4e5cf99") }
MongoDB server version: 4.0.0
rs0:PRIMARY> show dbs;
rs0:PRIMARY>

正如您所看到的,DB中没有内容。

CF是否会创建这样一个空的DB是期望的?根据来自群集描述的连接字符串,我应该使用

--username MyUserName --password <insertYourPassword>

我的代码没有什么特别之处:

  DBCluster:
    Type: AWS::DocDB::DBCluster
    Properties:
      DeletionProtection: True
      BackupRetentionPeriod : 7
      DBClusterIdentifier : !Ref DBClusterName
      DBClusterParameterGroupName : !Ref DBParameterGroup
      DBSubnetGroupName : !Ref DBSubnetGroup
      MasterUsername : MyUserName 
      MasterUserPassword : !Ref DocDBSecret
      Port : "27017"
      PreferredBackupWindow : "23:00-23:59"
      PreferredMaintenanceWindow : "sun:00:00-sun:05:00"
      VpcSecurityGroupIds:
        - !Ref DBSecurityGroup
      StorageEncrypted : true
      EngineVersion: 4.0.0

(如果需要,我可以粘贴我的模板的其他部分)

这种行为是否是预期的?

TIA

【以下的回答经过翻译处理】 好的,对不起,现在我理解了情况。 允许无用户名和密码的登录,但没有权限查看任何内容。 使用用户名和密码登录可以获得管理员访问权限:

[ec2-user@ip-10-8-54-91 ~]$ mongo --ssl --host docdb-2023-02-02-07-35-01.cluster-XYZ.us-east-1.docdb.amazonaws.com:27017 --sslCAFile rds-combined-ca-bundle.pem --username root --password passwd
MongoDB shell version v4.0.28
connecting to: mongodb://docdb-2023-02-02-07-35-01.cluster-XYZ.us-east-1.docdb.amazonaws.com:27017/?gssapiServiceName=mongodb
Implicit session: session { "id" : UUID("8e65f1c3-8512-4e68-9b2d-37a2a8eaf581") }
MongoDB server version: 4.0.0
