Meteor Up X (Development Version)

This is the latest development version of Meteor Up and known as mupx. Once mupx becomes stable we'll merge into master and release as mup.

Production Quality Meteor Deployments

Meteor Up is a command line tool that allows you to deploy any Meteor app to your own server. It currently supports Ubuntu. There are plans to support other linux distros soon.

You can use install and use Meteor Up from Linux, Mac and Windows.

This version of Meteor Up is powered by Docker and it makes Meteor Up easy to manage. It also reduce a lot of server specific errors.

Table of Contents


  • Single command server setup
  • Single command deployment
  • Multi server deployment
  • Environmental Variables management
  • Support for settings.json
  • Password or Private Key(pem) based server authentication
  • Access, logs from the terminal (supports log tailing)
  • Support for multiple meteor deployments (experimental)

Server Configuration

  • Auto-Restart if the app crashed
  • Auto-Start after the server reboot
  • Runs with docker so gives us better security and isolation.
  • Revert to the previous version, if the deployment failed
  • Secured MongoDB Installation (Optional)
  • Pre-Installed PhantomJS


npm install -g mupx

Creating a Meteor Up Project

mkdir ~/my-meteor-deployment
cd ~/my-meteor-deployment
mupx init

This will create two files in your Meteor Up project directory:

  • mup.json - Meteor Up configuration file
  • settings.json - Settings for Meteor's settings API

mup.json is commented and easy to follow (it supports JavaScript comments).

Setting Up a Server

mupx setup

This will setup the server for the mupx deployments. It will take around 2-5 minutes depending on the server's performance and network availability.

Deploying an App

mupx deploy

This will bundle the Meteor project and deploy it to the server. Bundling process is very similar to how meteor deploy do it.

Other Utility Commands

  • mupx reconfig - reconfigure app with new environment variables and Meteor settings
  • mupx stop - stop the app
  • mupx start - start the app
  • mupx restart - restart the app
  • mupx logs [-f --tail=50] - get logs

Build Options

When building the meteor app, we can invoke few options. So, you can mention them in mup.json like this:

"buildOptions": {
  // build with the debug mode on 
  "debug": true,
  // mobile setting for cordova apps 
  "mobileSettings": {
    "public": {
      "meteor-up": "rocks"
  // executable used to build the meteor project 
  // you can set a local repo path if needed 
  "executable": "meteor"

Additional Setup/Deploy Information

Deploy Wait Time

Meteor Up checks if the deployment is successful or not just after the deployment. By default, it will wait 15 seconds before the check. You can configure the wait time with the deployCheckWaitTime option in the mup.json

SSH keys with paraphrase (or ssh-agent support)

This only tested with Mac/Linux

It's common to use paraphrase enabled SSH keys to add an extra layer of protection to your SSH keys. You can use those keys with mup too. In order to do that, you need to use a ssh-agent.

Here's the process:

  • First remove your pem field from the mup.json. So, your mup.json only has the username and host only.
  • Then start a ssh agent with eval $(ssh-agent)
  • Then add your ssh key with ssh-add <path-to-key>
  • Then you'll asked to enter the paraphrase to the key
  • After that simply invoke mup commands and they'll just work
  • Once you've deployed your app kill the ssh agent with ssh-agent -k

Ssh based authentication with sudo

If your username is root or using AWS EC2, you don't need to follow these steps

Please ensure your key file (pem) is not protected by a passphrase. Also the setup process will require NOPASSWD access to sudo. (Since Meteor needs port 80, sudo access is required.)

Make sure you also add your ssh key to the /YOUR_USERNAME/.ssh/authorized_keys list

You can add your user to the sudo group:

sudo adduser *username*  sudo

And you also need to add NOPASSWD to the sudoers file:

sudo visudo

# replace this line
%sudo  ALL=(ALL) ALL

# by this line

When this process is not working you might encounter the following error:

'sudo: no tty present and no askpass program specified'

Server Setup Details

Meteor Up uses Docker to run and manage your app. It uses MeteorD behind the scenes. Here's how we manage and utilize the server.

  • your currently running meteor bundle lives at /opt/<appName>/current.
  • we've a demonized docker container running the above bundle.
  • docker container is started with --restart=always flag and it'll re-spawn the container if dies.
  • logs are maintained via Docker.
  • If you decided to use MongoDB, it'll be also running as a Docker conatiner. It's bound to the local interface and port 27017 (you cannot access from the outside)
  • the database is named <appName>

For more information see lib/taskLists.js.

Multiple Deployment Targets

You can use an array to deploy to multiple servers at once.

To deploy to different environments (e.g. staging, production, etc.), use separate Meteor Up configurations in separate directories, with each directory containing separate mup.json and settings.json files, and the mup.json files' app field pointing back to your app's local directory.

Accessing the Database

You can't access the MongoDB from the outside the server. To access the MongoDB shell you need to log into your server via SSH first and then run the following command:

docker exec -it mongodb mongo <appName>

Later on we'll be using a separate MongoDB instance for every app.

Server Specific Environment Variables

It is possible to provide server specific environment variables. Add the env object along with the server details in the mup.json. Here's an example:

  "servers": [
      "host": "hostname",
      "username": "root",
      "password": "password"
      "env": {
        "SOME_ENV": "the-value"

By default, Meteor Up adds CLUSTER_ENDPOINT_URL to make cluster deployment simple. But you can override it by defining it yourself.

Multiple Deployments

Meteor Up supports multiple deployments to a single server. Meteor Up only does the deployment; if you need to configure subdomains, you need to manually setup a reverse proxy yourself.

Let's assume, we need to deploy production and staging versions of the app to the same server. The production app runs on port 80 and the staging app runs on port 8000.

We need to have two separate Meteor Up projects. For that, create two directories and initialize Meteor Up and add the necessary configurations.

In the staging mup.json, add a field called appName with the value staging. You can add any name you prefer instead of staging. Since we are running our staging app on port 8000, add an environment variable called PORT with the value 8000.

Now setup both projects and deploy as you need.

Changing appName

It's pretty okay to change the appName. But before you do so, you need to stop the project with older appName

Custom configuration and settings files

You can keep multiple configuration and settings files in the same directory and pass them to mup using the command parameters --settings and --config. For example, to use a file mup-staging.json and staging-settings.json add the parameters like this:

mup deploy --config=mup-staging.json --settings=staging-settings.json

SSL Support

Meteor Up can enable SSL support for your app. It's uses the latest version of Nginx for that.

To do that just add following configuration to your mup.json file.

  "ssl": {
    "certificate": "./bundle.crt", // this is a bundle of certificates 
    "key": "./private.key", // this is the private key of the certificate 
    "port": 443 // 443 is the default value and it's the standard HTTPS port 

Now, simply do mup setup and then mup deploy. Now your app is running with a modern SSL setup.

To learn more about the SSL setup refer to the mup-frontend-server project.

Updating Mup

To update mupx to the latest version, just type:

npm update mupx -g

You should try and keep mupx up to date in order to keep up with the latest Meteor changes.


Check Logs

If you suddenly can't deploy your app anymore, first use the mupx logs -f command to check the logs for error messages.

One of the most common problems is your Node version getting out of date. In that case, see “Updating” section above.

Verbose Output

If you need to see the output of mupx (to see more precisely where it's failing or hanging, for example), run it like so:

DEBUG=* mupx <command>

where <command> is one of the mupx commands such as setup, deploy, etc.

Migrating from Meteor Up 0.x

mupx is not fully backward compatible with Meteor Up 0.x. But most of the mup.json remain the same. Here are some of the changes:

  • Docker is the now runtime for Meteor Up
  • We don't have use Upstart any more
  • You don't need to setup NodeJS version or PhantomJS manually (MeteorD will take care of it)
  • We use a mongodb docker container to run the local mongodb data (it uses the old mongodb location)
  • It uses a Nginx and a different SSL configurations
  • Now we don't re-build binaries. Instead we build for the os.linux.x86_64 architecture. (This is the same thing what meteor-deploy does)

Migration Guide

Use a new server if possible as you can. Then migrate DNS accordingly. That's the easiest and safest way.

Let's assume our appName is meteor

  • stop the app with stop meteor
  • Then remove upstrat config file: rm /etc/init/meteor.conf
  • stop stud if you are using SSL: stop stud
  • Then remove upstrat config file: rm /etc/init/stud.conf
  • Stop mongodb if you are using: stop mongod
  • Remove MongoDB with: apt-get remove mongodb

Then do mupx setup and then mupx deploy.
