using mongodb - get the ip of the container?

[goldylucks]

in my config file I've set the mongodb url to
mongodb://localhost/nodeparking_dev

but I'm getting this error:
Error: connect ECONNREFUSED 127.0.0.1:27017

is there a way for the node code to know what's the ip of the container?

do u have any examples using dockunit with a db?

[tlovett1]

Can you post the config file?

[goldylucks]

I've tried different types of node images
all make the same error

// server.js
var mongoose = require('mongoose');
var express = require('express');
var app = express();

var config = require('./config/config');

require('mongoose').connect(config.db.url);

// dev/tests
if (config.seed)
  require('./util/seed');

module.exports = app;

// config.js
  db: {
    url: "mongodb://localhost/nodeparking_test"
  }

// Dockunit.json
{
    "containers": [

        {
            "prettyName": "Node Latest",
            "image": "google/nodejs:latest",
            "beforeScripts": [
                "npm install",
                "npm install -g mocha"
            ],
            "testCommand": "mocha server/**/*.spec.js -w"
        }

    ]
}

Hey Adam, the google/nodejs image does not have Mongo in it. Here are your options:

1. Use a different image that has Node.js and Mongo.
2. Install Mongo as a part of beforeScripts (not recommended).
3. Create your own image using google/nodejs as a parent that installs Mongo.

Did you try the Dockunit.json wizard on Dockunit.io? It uses the dockunit/prebuilt-images:nodejs-mongodb-mocha-jasmine-4.2.1 image.

[goldylucks]

Which wizard?

I changed the image to dockunit/prebuilt-images:nodejs-mongodb-mocha-jasmine-4.2.1
but I still get the same error

which makes sense, since my app doesn't know the ip of the docker container, so I can't set it in my config file.

I have no way to hook the db to docker

Does this makes since?

does dockunit exposes any ENV_VARIABLES like it's ip?

so maybe I could go
url: "mongodb://${process.env.DOCKUNIT_IP}/nodeparking_test"

[tlovett1]

Hmm I see. Can't you just check if Dockunit is running and check Mongodb on localhost?

[goldylucks]

what do u mean check mongoDB on localost?

it is already pointing to localhost
mongodb://localhost/nodeparking_dev

[tlovett1]

So can't you just reference the Mongo instance like that? Why do you need the container IP?

[goldylucks]

because I get the reference error I posted
Error: connect ECONNREFUSED 127.0.0.1:27017

[tlovett1]

Hmm, I would debug by starting the Docker container manually and seeing what is going on with Mongo inside of it.
