如何将Micronaut API连接到docker容器中运行的MongoDB？

我正在尝试将Micronaut API服务连接到docker容器上运行的MongoDB。我按照本指南中的步骤为MongoDB创建身份验证，但在Micronaut应用程序中创建客户端时，它说：

17:51:15.346 [pool-1-thread-1] ERROR c.ds.events.service.EventsService - com.mongodb.MongoSecurityException: Exception authenticating MongoCredential{mechanism=SCRAM-SHA-1, userName='admin', source='admin', password=<hidden>, mechanismProperties=<hidden>}

然后，我关闭了mongo实例，并使用身份验证凭据重新登录：

mongo -u admin -p admin --authenticationDatabase admin

我能够成功登录，并且可以将数据插入数据库。但是当试图通过Micronaut连接到它时，我会得到身份验证错误

以下是我的Micronaut API应用程序的一个片段：

    @Value("\${MONGO_PASS}")
    var pass: String = "admin"

    @Value("\${MONGO_USER}")
    var user: String = "admin"

    @Value("\${MONGO_HOST}")
    var host: String = "localhost"

    @Value("\${MONGO_PORT}")
    var port: String = "27017"

    @Value("\${MONGO_DB_NAME}")
    var database: String = "admin"

    @Value("\${MONGO_COLLECTION}")
    var collectionName: String = "events"

    init {
        val client = KMongo.createClient(
                ServerAddress(host, port.toInt()),
                listOf(MongoCredential.createCredential(
                        user,
                        database,
                        pass.toCharArray()
                )),
                MongoClientOptions.builder().build())
        val database = client.getDatabase(database)
        collection = database.getCollection(collectionName)
    }

我没有设置任何环境变量，所以它应该使用默认值。以下是运行服务后的完整日志

所以我解决了这个问题。

27017

端口上运行的其他进程导致冲突。关闭端口上的所有进程并重新运行docker和Micronaut服务器解决了此问题。

您是如何启动容器的？（您是否将MongoDB服务器端口发布到主机？）以及，客户端是在另一个容器中运行还是直接在主机上运行？

docker run-d-p 27017-27019:27017-27019——命名MongoDB mongo

和

docker exec-it MongoDB bash

运行Mongoth此客户端直接在主机上运行
