Server Configuration

Installation

npm install -g mup

mup should be installed on the computer you are deploying from.

Creating a Meteor Up Project

cd my-app-folder
mkdir .deploy
cd .deploy
mup init

WARNING: Windows users need to use mup.cmd instead, as mup will result in unexpected behavior.

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

Setting Up a Server

mup setup

Running this locally will set up the remote servers you have specified in your config. It will take around 2-5 minutes depending on the server’s performance and network availability.

It is safe to run mup setup multiple times if needed. After making changes to custom SSL certificates, MongoDB, or servers in your config, you need to run mup setup for the changes to take effect.

Deploying an App

mup deploy

This will bundle the Meteor project locally and deploy it to the remote server(s). The bundling process is the same as what meteor deploy does.

mup deploy --cached-build

The --cached-build option will use the build from the last time you deployed the app. This is useful when the previous deploy failed from a network error or from a problem in the config.

Other Utility Commands

Meteor Support

Mup supports Meteor 1.2 and newer, though you might need to change the docker image in your mup config.

Meteor version Docker image Prepare Bundle Notes
1.2 - 1.3 kadirahq/meteord false This is the default docker image. When using Meteor 1.2, app.buildOptions.serverOnly should be false.
1.4 - 1.5 abernix/meteord:base true  
1.6 abernix/meteord:node-8.4.0-base true  
1.2 - 1.6 zodern/meteor:root true Automatically uses the correct node version.

When using an image that supports Prepare Bundle, deployments are easier to debug and more reliable.

Build Options

You can define Meteor build options in mup.js like this:

...
app: {
  buildOptions: {
    // Set to true to disable minification and bundling,
    // and include debugOnly packages
    debug: false,
    // 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. It will wait 15 seconds after starting the docker container before starting the checks. The check runs every second until it either can successfully load the app’s client, or it runs out of time as defined in meteor.deployCheckWaitTime.

Deploy check port

If you are deploying under a proxy/firewall and need a different port to be checked after deploy, add a variable called deployCheckPort with the value of the port you are publishing your application to.

app: {
 ...
  deployCheckPort: 80
 ...
}

SSH keys with passphrase (or ssh-agent support)

This only tested with Mac/Linux

It’s common to use passphrase 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 ssh-agent.

Here’s the process:

SSH based authentication with sudo

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

Please ensure your key file (pem) is not protected by a passphrase. This 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
%sudo ALL=(ALL) NOPASSWD:ALL

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.

Deploy to multiple servers

Add all of the servers to the servers object and modify app.servers to include them.

Multiple Deployment Environments

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

Multiple Deployments

Meteor Up supports multiple deployments to a single server. To route requests to the correct app, use the reverse proxy.

Let’s assume we need to deploy production and staging versions of the app to the same server. The production is at myapp.com, and staging is at staging.myapp.com.

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

In the staging mup.js, change the field app.name to have the value staging. You can add any name you prefer instead of staging.

Next, add the proxy object to both configs. For your production app, it would be:

module.exports = {
  // ... rest of config

  proxy: {
    domains: 'myapp.com'
  }
};

For the staging app, proxy.domains would be staging.myapp.com.

Now, set up both projects and deploy the apps.

Docker options

Customize docker image

During Prepare Bundle, mup builds a new docker image that includes your app’s code. You can customize this image by adding additional build instructions that are run before adding your app. This can be used to install dependencies your app needs, such as adding imagemagick or node-canvas’s dependencies.

You can add instructions with app.docker.buildInstructions. An example is:

module.exports = {
  app: {
    name: 'app',
    path: '../',
    servers: { one: {} },
    docker: {
      buildInstructions: [
        'RUN apt-get update && apt-get install -y imagemagick'
      ]
    }
  }
};

Each item is added on a new line in the Dockerfile, and should start with RUN, USER, or another dockerfile instruction. If the base docker image runs the app as a non-root user, you might need to switch the user to root for your RUN commands, and back to the non-root user afterwards.

After changing the config, run mup deploy.

Listening to specific IP address (IP Binding)

If you want Docker to listen only on a specific network interface, such as 127.0.0.1, add a variable called bind with the value of the IP address you want to listen to.

app: {
 ...
 docker: {
  ...
  bind: '127.0.0.1'
  ...
 }
}

Docker networks

If you need to connect your docker container to one or more networks add a variable called networks inside the docker configuration. This is an array containing all network names to which it has to connect.

app: {
 ...
  docker: {
    ...
    networks: [
      'myNetwork1'
    ]
    ...
  }
 ...
}

Custom Docker Registry

Simply reference the docker image by url in the meteor.docker.image setting:

app: {
 ...
  docker: {
    ...
    image: 'registry.gitlab.com/someregistry/someimage:sometag'
  }
}

And then add a docker setup hook to login to your private registry on the server. See Hooks for example of logging into a private docker registry.

Image Port

You can set meteor.docker.imagePort to the port to expose from the container. This does not affect the port the app is accessed on, only the port the app runs on inside the docker container.

Reverse Proxy

Meteor Up can create a nginx reverse proxy that will handle SSL, and, if you are running multiple apps on the server, it will route requests to the correct app. The proxy is shared between all apps on the servers.

This replaces the former nginx setup, configured using meteor.ssl and meteor.nginx.

Remove meteor.ssl and meteor.nginx from your config and add a proxy section:

module.exports = {
  // ... rest of config

  proxy: {
    // comma-separated list of domains your website
    // will be accessed at.
    // You will need to configure your DNS for each one.
    domains: 'website.com,www.website.com'
  }
};

The first time you setup the reverse proxy, you need to stop every app running on the servers:

mup stop

Then, run

mup setup
mup reconfig

SSL

Add an ssl object to your proxy config:

module.exports = {
  // ... rest of config

  proxy: {
    domains: 'website.com,www.website.com',
    ssl: {
      // Enable let's encrypt to create free certificates.
      // The email is used by Let's Encrypt to notify you when the
      // certificates are close to expiring.
      letsEncryptEmail: 'email@domain.com'
    }
  }
};

For Let’s Encrypt to work, you also need to:

  1. Make sure meteor.env.ROOT_URL starts with https://
  2. Setup DNS for each of the domains in proxy.domains to point to the server
  3. Open port 80 if it isn’t. That port is used to verify that you control the domain.

After changing the config, run mup setup and mup reconfig. It will automatically create the certificates and setup SSL, which can take up to a few minutes. The certificates will be automatically renewed when they expire within 30 days.

If you are using custom certificates instead, it would look like:

module.exports = {
  // .. rest of config

  proxy: {
    domains: 'website.com,www.website.com',
    ssl: {
      crt: './bundle.crt',
      key: './private.pem'
    }
  }
};

Then run mup setup.

You can view the list of certificates and when they expire by running mup status.

Redirect http to https

In your config, add:

module.exports = {
  // ... rest of config

  proxy: {
    domains: 'website.com,www.website.com',
    ssl: {
      forceSSL: true
    }
  }
};

It uses HSTS. This means that if you set it to false after it’s been true, the browser used by anyone that visited it while it was set to true will still be redirected to https for one year.

Custom NGINX Config

The nginx config is generated based on the docker containers running on the same server. At this time, it is not possible to modify the majority it. However, you can modify the server and / location blocks for the app. It is also possible to add a config that is used proxy-wide, and can add additional upstream and server blocks.

To extend the server block for the app, save the rules to a file and add the path to your config:

module.exports = {
  // ... rest of config

  proxy: {
    domains: 'website.com',
    nginxServerConfig: './path/to/config'
  }
};

To modify the / location block, save the rules to a file and add the path to your config:

module.exports = {
  // ... rest of config

  proxy: {
    domains: 'website.com',
    nginxLocationConfig: './path/to/config'
  }
};

To learn about the nginx config used proxy-wide, look at the proxy.shared example in the advanced configuration docs.

You can view the generated config by running

mup proxy nginx-config

There will be include statements for each custom config.

Advanced configuration

These are additional options that can be used to customize the reverse proxy. The defaults are compatible with most apps.

module.exports = {
  // ... rest of config

  proxy: {
    domains: 'website.com,www.website.com',

    // (optional, default=10M) Limit for the size of file uploads.
    // Set to 0 disables the limit.
    clientUploadLimit: '50M'
  }
};

The proxy.shared object has settings that most apps won’t need to change, but if they are they apply to every app using the proxy. After you change proxy.shared, you need to run mup proxy reconfig-shared for it to take effect.

module.exports = {
  // ... rest of config

  proxy: {
    domains: 'website.com,www.website.com',

    // Settings in "proxy.shared" will be applied to every app
    // deployed on the servers using the reverse proxy.
    // Everything is optional.
    // After changing this object, run `mup proxy reconfig-shared`
    shared: {
      // The port number to listen to for http connections. Default 80.
      httpPort: 80,
      // The port to listen for https connections. Default is 443.
      httpsPort: 443,
      // Add an nginx config that is used proxy-wide.
      // This config can add additional upstream and server blocks if needed.
      nginxConfig: './path/to/config',
      // Environment variables for nginx proxy
      env: {
        DEFAULT_HOST: 'foo.bar.com'
      },
      // env for the jrcs/letsencrypt-nginx-proxy-companion container
      envLetsEncrypt: {
        // Directory URI for the CA ACME API endpoint
        // (default: https://acme-v01.api.letsencrypt.org/directory).
        // If you set it's value to
        // https://acme-staging.api.letsencrypt.org/directory
        // letsencrypt will use test servers that
        // don't have the 5 certs/week/domain limits.
        ACME_CA_URI: 'https://acme-v01.api.letsencrypt.org/directory',

        // Set it to true to enable debugging of the entrypoint script and
        // generation of LetsEncrypt certificates,
        // which could help you pin point any configuration issues.
        DEBUG: true
      }
    }
  }
};

Changing the App’s Name

It’s okay to change app.name. But before you do so, you need to stop the project with older appName. Also, if you use the built-in MongoDB, mup will create a new database with the new name so you will need to migrate the data.

  1. Run mup stop
  2. Change the app name in the config
  3. Run mup setup and mup deploy

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.js and staging-settings.json, add the parameters like this:

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

SSL Support

This is depreciated. Use the reverse proxy to setup ssl instead.

Meteor UP can enable SSL support for your app. It can either autogenerate the certificates or upload them from your dev computer.

Autogenerate certificates

This is depreciated. Use the reverse proxy to setup ssl instead.

Meteor Up can use Let’s Encrypt to generate certificates for you. Add the following to your mup.js file:

app: {
  ...
  ssl: {
    autogenerate: {
      email: 'email.address@domain.com',
      domains: 'website.com,www.website.com'
    }
  }
}

You also need to:

  1. Make sure meteor.env.ROOT_URL starts with https://
  2. Set up DNS for each of the domains in meteor.ssl.autogenerate.domains

Then run mup deploy. It will automatically create certificates and set up SSL, which can take up to a few minutes. The certificates will be automatically renewed when they expire within 30 days.

Upload certificates

This is depreciated. Use the reverse proxy to setup ssl instead.

To upload certificates instead of having the server generate them for you, just add the following configuration to your mup.js file.

app: {
  ...
  ssl: {
    crt: './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. Your app is now running with a modern SSL setup.

If your certificate and key are already in the right location on your server and you would like to prevent Mup from overriding them while still needing an SSL setup, you can add upload: false in the meteor.ssl object.

To learn more about SSL setup when using your own certificates, refer to the mup-frontend-server project.

Nginx Upload

This is depreciated. Use the reverse proxy to configure this instead.

This Only Works if you are using the Let’s Encrypt Autogenerated SSL’s

If you would like to increase the client upload limits, you can change it by adding:


app: {
   ...
   nginx: {
     clientUploadLimit: '<desired amount>' // Default is 10M
   }
   ...
}

MongoDB

External Database

To use an external database:

  1. Remove the mongo object from your config
  2. Set meteor.env.MONGO_URL to point to the external Mongo instance

Two popular Mongo DbaaS’s are Compose and mLab.

Built-in Database

Meteor Up can start a MongoDB instance on the server and set meteor.env.MONGO_URL to connect to it.

It is recommended to use an external database instead of the one built-in to mup for apps in production. The built-in database is not easy to backup, and only works when the app is running on one server.

Add the mongo object to your config:

module.exports = {
  // .. rest of config

  mongo: {
    version: '3.4.1',
    servers: {
      one: {}
    }
  }
};

To use the oplog, set app.env.MONGO_OPLOG_URL to mongodb://mongodb/local.

Before your first setup, it is recommended to change mongo.version to the newest version of MongoDB your app or meteor supports. After Mongo is started, it is more complex to upgrade it.

After you finished changing the config, run

mup setup

and

mup deploy

Multiple apps use the same database

It is possible for two apps to use the same database from the built-in MongoDB instance.

In the config for one of the apps, follow the instructions for Built-in Database.

For the other apps:

  1. Make sure the mongo object is not in the config
  2. Change env.MONGO_URL to mongodb://mongodb:27017/<app1 name>
  3. Change meteor.docker.args to [ '--link=mongodb:mongodb' ]. meteor.docker will look similar to:
    docker: {
      // change to 'kadirahq/meteord' if your app is using Meteor 1.3 or older
      image: 'abernix/meteord:base',
      args: [
        '--link=mongodb:mongodb'
      ]
    }

Accessing the Database

You can’t access the MongoDB from 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>

View MongoDB Logs

If you are experiencing problems with MongoDB (such as it frequently restarting), you can view the logs with

mup mongo logs

Backup and restore

For backup you can use:

ssh root@host "docker exec mongodb mongodump -d meteor --archive --gzip" > dump.gz

and for restore:

cat dump.gz | ssh root@host "cat | docker exec -i mongodb mongorestore --archive --gzip" # use --drop if you want to drop existing collections first

Change MongoDB Version

If you have not deployed to the server, you can change the mongo version by adding:


mongo: {
  ...
  version: '<desired version>'
}

If you have deployed to the server, it involves a couple more steps.

  1. Go to the MongoDB manual > Release Notes > Current version of MongoDB > Upgrade or Downgrade Standalone
  2. Follow the directions listed there. You can access the MongoDB console by running docker exec -it mongodb mongo on the server.
  3. During the steps for install or replace binaries or restarting MongoDB, instead change the version in your mup.js and run mup setup.
  4. To verify that it worked, run docker ps to check if MongoDB keeps restarting. If it is, you can see what the problem is with docker logs mongodb

Hooks

Hooks allow you to run a command or function before or after a CLI command is run. The config looks like:

const childProcess = require('child_process');

module.exports = {
  hooks: {
    hookName: {
      localCommand: 'command to run on computer',
      remoteCommand: 'command to run on every server'
    },
    'pre.deploy': {
      localCommand: 'npm prune --production'
    },
    'post.meteor.restart': {
      remoteCommand: 'docker logs --tail 50 app-name'
    },
    'pre.reconfig'(api) {
      // Same api as is given to plugin command handlers
      // If this runs asynchronous tasks, it needs to return a promise.
      const gitHash = childProcess.execSync('git rev-parse HEAD').toString().trim();

      api.getSettings();
      api.settings.GIT_HASH = gitHash;
    },
    'post.docker.setup'(api) {
      // Login to private Gitlab docker registry
      const config = api.getConfig();
      const registry = 'registry.gitlab.com';
      const username = process.env.REGISTRY_USERNAME;
      const password = process.env.REGISTRY_PASSWORD;

      if (!username || !password) {
        throw new Error(
          'You must provide registry login details'
        );
      }

      return api.runSSHCommand(
        config.servers.one,
        `docker login -u ${username} -p ${password} ${registry}`
      );
    }
  }
};

The hook name format is {pre or post}.topLevelCommand.subCommand. For example, if you want a command to run after mup deploy, the hook name would be post.deploy. Or if you want it to run after mup mongo restart, the hook name would be post.mongo.restart.

Some CLI commands run other CLI commands. For example, mup setup runs mup docker setup and mup mongo setup. To see all of the available hooks while a command runs, use the --show-hook-names option.

Updating Mup

To update mup to the latest version, just type:

npm install -g mup

mup usually will let you know when there is an update available. You should try and keep mup up to date in order to keep up with the latest Meteor changes.

Troubleshooting

Check Logs

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

You can also view logs for:

Run mup status

mup status checks the servers for any potential problems, as well as shows you the status of any docker containers or services running on the servers.

Docker image

Make sure that the docker image you are using supports your app’s meteor version.

Update Docker

Some problems are caused by old versions of docker. Since mup 1.3, mup setup and mup docker setup will update Docker if it is older than 1.13.

Check if Docker Containers are Restarting

You can view a list of Docker containers with

mup docker ps

and check the STATUS column.

Verbose Output

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

DEBUG=mup* mup <command> --verbose

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

The environment variable DEBUG=mup* gives more information on what the mup CLI is doing.

The --verbose flag shows output from commands and scripts run on the server.

Common Problems

Verifying Deployment: FAILED

If you do not see => Starting meteor app on port in the logs, your app did not have enough time to start. Try increase meteor.deployCheckWaitTime. This only applies if Prepare Bundle is disabled.

If you do see it in your logs, make sure your ROOT_URL starts with https or http, depending on if you are using SSL or not. If that did not fix it, create a new issue with your config and output from mup deploy --verbose.

If you are using Meteor 1.3, you might see this error:

/bundle/bundle/programs/server/node_modules/fibers/future.js:280
						throw(ex);
						^

ReferenceError: module is not defined
    at app/mup.js:1:-27

This error happens when your config gets bundled with the app. Try moving it and your settings.json to a hidden folder (such as app/.deploy) or to a location outside of the app’s folder.

Mup silently fails, mup.js file opens instead, or you get a Windows script error

If you are using Windows, make sure you run commands with mup.cmd <command> instead of mup <command>, or use PowerShell. If it silently fails for a different reason, please create an issue.

Error: spawn meteor ENOENT

Make sure meteor is installed on the computer you are deploying from.

Let’s Encrypt is not working

Make sure your meteor.env.ROOT_URL starts with https://. Also, check that the DNS for all of the domains in ssl.autogenerate.domains is correctly configured to point to the server. Port 80 needs to be open on the server so it can verify that you control the domain.

You can view the Let’s Encrypt logs by running this command on the server:

docker logs <AppName>-nginx-letsencrypt

Replace <AppName> with the name of the app.

Prepare Bundle ends with Killed

The server ran out of memory during npm install. Try increasing the server’s ram or creating a swap file.

Unwanted redirects to https

Make sure force-ssl is not in .meteor/versions. If it is, either your app or a package it uses has force-ssl as a dependency.

Migration Guide

mup is not backward compatible with Meteor Up 0.x. or mupx.

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

Migrating from Mupx

Let’s assume our appName is meteor

Remove old docker container with docker rm -f meteor Remove old mongodb container with docker rm -f mongodb If present remove nginx container with docker rm -f meteor-frontend

The new config format is different from mupx. Run mup init to create a new config file. Then do mup setup and then mup deploy.
