MongoDB, Docker, Meteor: Connection Refused
Meteor works perfectly if I run “meteor“. If I setup MongoDB and run Meteor with MONGO_URL set to “mongodb://127.0.0.1:27017/meteor” then it too works perfectly. However, if I run a Docker Container that calls exactly the same Meteor files on the same machine with the MONGO_URL set as above then I get the error: “Exception in callback of async function: Error: failed to connect to [127.0.0.1:27017]”. Logic would state that the introduction of Docker is causing the problem. Therefore, is there something I must do to specifically allow Meteor to call MongoDB from inside a container – such as something additional with the MongoDB ports etc.

Meteor is called with the following:
docker run --name meteor-dev -it -p 3000:3000 -v /machine/meteor:/opt/meteor -w /opt/meteor meteor-dev

When you are running a container it creates its own network which is isolated from host network.
So when you are tying to connect to Mongo using “mongodb://127.0.0.1:27017/meteor it searches for MongoDB inside your container.
Instead of using 127.0.0.1 use the host ip addresss or hostname.
Or if your MongoDB is running from a container create a link and use the link to start meteor container. Hope this helps
