如何使用新的服务器发现和监控传递选项｛useUnifiedTopology:true｝到Docker中的MongoCli

Question

我是docker的新手。我正在尝试在同一个docker网络中配置mongodb和mongoexpress。我创建了一个名为some network的网络。然后我用这个命令运行mongodb，在同一个网络中设置mongo，我运行命令：

docker run -d --network some-network --name some-mongo                     
-e MONGO_INITDB_ROOT_USERNAME=mongoadmin 
-e MONGO_INITDB_ROOT_PASSWORD=secret 
mongo

然而，当我运行配置mongo express的命令时，我得到了一个错误：

docker run --network some-network -e ME_CONFIG_MONGODB_SERVER=some-mongo -p 8081:8081 mongo-express
Welcome to mongo-express

我错过了什么吗？，如何使用新的服务器发现和监控引擎，将选项｛useUnifiedTopology:true｝传递到docker中的MongoClient构造函数？

我不知道问题出在哪里，但运行这些命令解决了问题

设置mongodb

docker run --network some-network -e ME_CONFIG_MONGODB_SERVER=some-mongo -e ME_CONFIG_MONGODB_ADMINUSERNAME=mongoadmin -e ME_CONFIG_MONGODB_ADMINPASSWORD=secret -p 8081:8081 mongo-express

然后mongo express：

Docker run --name mongo-express --network some-network -e ME_CONFIG_MONGODB_SERVER=some-mongo -e ME_CONFIG_MONGODB_ADMINUSERNAME=mongoadmin -e ME_CONFIG_MONGODB_ADMINPASSWORD=secret -p 8081:8081 mongo-express
