Unable to connect to mongoDB using fig

[jonaswindey]

When I try to launch the application locally with 'fig up', the application can't connect to mongoDB.

Howerver, 'docker ps' lists the containers and the ports (+ forwarding) are looking fine:

Anyone an idea? I'm new to fig/docker but I'm very interested to start using it. Thanks

Ok, I have found a possible explanation, I'm using boot2docker on OSx (https://github.com/boot2docker/boot2docker) which apparently uses NAT forwarding.

This means that I can't use 0.0.0.0 or localhost, but I have to use the ip that boot2docker provides

bash-3.2$ boot2docker ip

The VM's Host only interface IP address is: 192.168.59.103

So now I'll have to investigate how to forward this ip (which is probably dynamicly created) to fig or the mean project docker's mongodb ip

I've got this problem too.

A slight change to the db configuration in config/env/development.js should make it work.

module.exports = {
    db: 'mongodb://' + (process.env.DB_1_PORT_27017_TCP_ADDR || 'localhost') + '/mean-dev',
