    Deploying Rocket.Chat on Galaxy

    Galaxy is a platform-as-a-service built specifically for Meteor apps. Built using the latest Docker and AWS cloud infrastructure.

    You will need to sign up for Galaxy.

    Get Rocket.Chat code

    Download the source code first to be able to deploy to Galaxy

    git clone
    cd Rocket.Chat

    Set your MongoDB URL

    You will need a Mongo database configured for your Rocket.Chat application, for better performance, as meteor hosting uses AWS. It is advised that you setup your database in the same AWS region.

    Create a settings.json file to set the environmental variable as follows:

      "": {
        "env": {
          "MONGO_URL": "mongodb://<user>:<password>@<host>:<port>/<database>?replicaSet=rs01",
          "MONGO_OPLOG_URL": "mongodb://<oplog_username>:<oplog_password>@<db_server_host>:<db_server_port>/<oplog_db_name>?authSource=admin&replicaSet=rs01",
          "ROOT_URL": "...",
          "MAIL_URL": "...",

    Deploy to Galaxy servers

    Execute this from the root of the source code:

    DEPLOY_HOSTNAME=[region] meteor deploy [hostname] --settings [filepath.json]
    • region is ‘’ for US East, ‘’ for EU West, and ‘’ for Asia-Pacific.

    • hostname is the fully qualified domain name where you’re planning to host your application (using the hostname format, in this example).

    • filepath.json is the path to your settings file (for example, ‘./settings.json’).
