docker-compose MongoDB错误：尝试在主机上运行命令“ isMaster”时出现网络错误 [英] docker-compose MongoDB Error: network error while attempting to run command 'isMaster' on host

问题描述

我正在尝试使用mongo从外部连接到docker容器中的mongodb，但出现以下错误。

I`m trying to connect to mongodb in docker container from outside with mongo, but I get the following error.

MongoDB shell version v3.6.5
connecting to: mongodb://127.0.0.1:27017
2018-05-30T14:54:13.950+0200 E QUERY    [thread1] Error: network error while attempting to run command 'isMaster' on host '127.0.0.1:27017'  :
connect@src/mongo/shell/mongo.js:251:13
@(connect):1:6
exception: connect failed

当我向容器重击时，一切都很好。
它可能在半年前就可以了，但现在不行了。
我认为docker-compose存在问题，但我不明白。

When I bash into the Container everything is fine. It was working maybe half a year ago but now it won't. I think it's a problem with docker-compose, but I don't get it.

shell和服务器的版本相同。
为了测试，这是我的docker-compose.yaml

The versions of the shell and server are the same. For testing this is my docker-compose.yaml

version: '3'

  backend:
    external:

推荐答案

我遇到了同样的问题
我通过在mongos中添加以下关键字来解决它：-bind_ip_all

所以
更改：

mongos --port 27017 --configdb configserver/config01:27017,config02:27017,config03:27017 

到：

 mongos --bind_ip_all --port 27017 --configdb configserver/config01:27017,config02:27017,config03:27017
