部署了 Strimzi Kafka、Strimzi Zookeeper 和 Debezium mongodb 连接器，并配置了 Debezium mongodb，

curl 'http://my-connect-cluster-connect-api:8083/connectors' -X POST -i -H "Content-Type:application/json" -d '{
  "name": "mongodb-connector", 
  "config": {
    "connector.class": "io.debezium.connector.mongodb.MongoDbConnector",
    "mongodb.hosts": "MainRepSet/mongod-0.mongodb-service.kafka.svc.cluster.local:27017,mongod-1.mongodb-service.kafka.svc.cluster.local:27017,mongod-2.mongodb-service.kafka.svc.cluster.local:27017", 
    "mongodb.name": "MainRepSet", 
    "collection.whitelist": "springdatabase[.]*",
    "mongodb.user": "springuser",
    "mongodb.password": "password"
  }
}'

但是得到了身份验证异常，

2019-01-29 13:13:40,170 ERROR Error while reading the 'shards' collection in the 'config' database: Timed out after 30000 ms while waiting to connect. Client view of cluster state is {type=UNKNOWN, servers=[{address=mongod-2.mongodb-service.kafka.svc.cluster.local:27017, type=UNKNOWN, state=CONNECTING, exception={com.mongodb.MongoSecurityException: Exception authenticating MongoCredential{mechanism=null, userName='springuser', source='admin', password=<hidden>, mechanismProperties={}}}, caused by {com.mongodb.MongoCommandException: Command failed with error 18: 'Authentication failed.' on server mongod-2.mongodb-service.kafka.svc.cluster.local:27017.

以及我通过以下语句创建的 mongodb 帐户，

db.createUser({user:"springuser",pwd:"password",roles:[{role:"readWrite",db:"springdatabase"}]})

经过分析异常，默认使用的是Debezium mongodb authSource "source='admin'"，但是我的mongodb账号的authSource是'springdatabase'，我认为是认证失败的原因。

解决方法之一是使用默认的“admin”创建 mongodb 帐户。但是我们的生产 mongodb 帐户已经创建，所以我们无法更改它。

那么是否有任何配置属性来设置“authSource”？

事实上，Debezium 对管理员连接进行了硬编码，这可能是因为方便，因为它需要从 oplog 中读取。

我看到您在项目本身中创建了一个错误，但如果您想拥有 - 目前 - 所需的安全数量的权限，您可以：

// Create a role which allows to list the databases
db.runCommand({createRole:"listDatabases",privileges:[{resource:{cluster:true},
           actions:["listDatabases"]}],roles:[]})

// Create a user which can, list the databases, read the oplog (local db), and read the source database (for initial syncs)
db.createUser({
"user" : "debezium_read_only",
    "roles" : [
        {
            "role" : "justListDatabases",
            "db" : "admin"
        },
        {
            "role" : "read",
            "db" : "database_where_collections_are"
        },
        {
            "role" : "read",
            "db" : "local"
        }
    ]
})

我希望这有助于保护您的设置，直到在 Debezium 中提供更好的登录选项。

恐怕这是 hrad 编码的。您能否提出一个 Jira 功能请求，以便我们看看？
