docker for mac：从另一个容器访问 mongo

Question

I have two container, one is a container for node.js code and another for a mongodb database. I set the network_mode to host for both containers, there are certain network restrictions making me have to do this. Additionally, both container are on the same physical mac machine. If I want to connect to the mongodb database from the node.js container, what should my connection string look like. I know that if I used a bridged network, I would use the name of the mongo container for the host name. However, in this case I have tried localhost, 0.0.0.0, 127.0.0.1, etc. none of which are working. How would I access the mongdb database in this case?

Answer 1

easiest way to use docker inspect and find the IP of the docker container and login/connect to it. Alternatively you can use VS Code ( https://code.visualstudio.com/download ) and install docker plugin

find running docker containers and container ids

docker ps

get details of the docker specific docker container

docker inspect <CONTAINER ID> | grep "IPAddress"

example

    "SecondaryIPAddresses": null,
    "IPAddress": "172.17.0.2",
            "IPAddress": "172.17.0.2",

VS Code docker plugin

According to this github issue , network_mode doesn't work on Docker for Mac.

The comment on the issue I linked did say that if you need to access a service on the host from a container, you can use host.docker.internal , but this might not be relevant to your use case.
