Mongodb. Docker. SocketException: Error connecting to 127.0.0.1:27017-CodePudding

I'm using Docker Desktop and trying to start 2 containers: mongodb and configuration/export for mongo db. I can successfully start mongodb container. From command line:

 TCP    127.0.0.1:27017        0.0.0.0:0              LISTENING

But with "configure mongo" container have the following issue:

exception: connect failed

MongoDB shell version v4.0.5

connecting to: mongodb://127.0.0.1:27017/testDb?gssapiServiceName=mongodb

CodePudding user response：

You need to use the service name (or container name/id) as hostname. The error says:

Error: couldn't connect to server 127.0.0.1:27017

So you are trying to connect to an instance running inside the configure-mongodb container, while you actually want to connect to the mongodb container.

Use the below instead:

mongodb://mongodb:27017/testDb?gssapiServiceName=mongodb
