mongodb - 尝试在副本集独立 mongodb 中连接时错误的连接字符串

Question

我正在尝试创建一个仅用于测试事务的 mongo 服务器，为此我必须创建一个副本集。

我通过 docker-compose 将独立的 mongodb 转换为副本集：

  mongo:
    image: mongo:latest
    container_name: test-mongodb
    command: '--storageEngine wiredTiger --replSet rs0 --bind_ip_all --noauth'
    environment:
      MONGO_INITDB_DATABASE: testdb
      MONGO_REPLICA_SET_NAME: rs0
    ports:
      - '27017:27017'
    healthcheck:
      test: test $$(echo "rs.initiate().ok || rs.status().ok" | mongo --quiet) -eq 1
      interval: 10s
      start_period: 30s

rs.status()

{

        "signature" : {
            "hash" : BinData(0,"AAAAAAAAAAAAAAAAAAAAAAAAAAA="),

        }
    },
    "operationTime" : Timestamp(1614179254, 1)
}

当我尝试通过连接字符串进行连接时： mongo --host mongodb://localhost:27017/?replicaSet=rs0

收到错误：

Error: connect failed to replica set rs0/localhost:27017 

我可以只使用 1 个默认节点吗？

我连接到主服务器的有效连接字符串是什么？
