title: MongoDB / Meteor / Export MONGO_URL to deployed applications
body: <p>I tried to export a settings.json as documented in the meteor.js documentation in order to connect my Meteor.js app with an external MongoHQ database :</p>
  
  <pre><code>{
      "env": {
          "MONGO_URL" : "mongodb://xxx:xxxx@troup.mongohq.com:10037/xxx"
      }
  }
  </code></pre>
  
  <p>with the command : </p>
  
  <pre><code>mrt deploy myapp.meteor.com --settings settings.json
  </code></pre>
  
  <p>It doesn't even work, My app continue to connect the local database provided with the Meteor.app !
  My MONGO_URL env variable didnt changed.</p>
  
  <p>Is there any solution to export my MONGO_URL env variable to connect an external MongoDB database ? </p>
  
  <p>I saw that is possible to change it while using heroku or modulus, what about the standard deploying meteor.com solution ? </p>
