Question

我无法从主机（macOS 10.14.5）连接到在Docker容器（Docker版本18.09.2，内部版本6247962）中运行的mongod。我使用--network host选项启动容器，并将mongod设置为监听0.0.0.0。

docker run --network host --name testmongo -it mongo:latest /bin/bash
root@linuxkit-025000000001:/# mongod --bind_ip 0.0.0.0

我现在希望我可以在主机上访问localhost:27017并连接到mongod服务器，但是我一直收到Connection Refused的响应。从jupyter console并使用pymongo：

In [1]: import pymongo                                                                                                                                     

In [2]: client = pymongo.MongoClient(host='localhost', port=27017)                                                                                         

In [3]: client.list_database_names()  

---------------------------------------------------------------------------

----> 1 client.list_database_names()

[LONG ERROR MESSAGE]

ServerSelectionTimeoutError: localhost:27017: [Errno 61] Connection refused

任何对我在这里做错事的见解都将受到赞赏。

根据此link，network host仅在Linux主机上有效，而在MacO的Docker Desktop上无效。

要解决此问题，请使用-p之类的-p 27017:27017选项运行docker

例如： docker run -d -p 27017:27017 -v ~/data:/data/db mongo

从主机连接到运行MongoDB的Docker容器
