#meteor-deployment-manager Meteor Deployment Manager (or MDM for short) is a command line tool intended to automate the process of deploying your Meteor applications to self-hosted infrastructure like Amazon EC2.

NB: You have found this project in its infancy. The best documentation at the moment is the source code, so check it out!

##Features

• Written in pure JavaScript.
• Installs as a global NPM package, accessible from any directory.
• Supports multiple deployment environments and configurations.
• Supports the use of Meteor's Meteorite package manager.
• Supports predefined password, private key and keyboard-interactive authentication.
• Keeps a specifiable number of builds.
• Uses symbolic links to retain build history and allow for instant build rollbacks.
• Uses Upstart to monitor Node.js.

##How it works

MDM makes itself available with the mdm command line program. By default, it looks for a deployment configuration file named deploy.json in the current working directory. You can change this behaviour with the --project-path and --config-file command line options.

Usage:

$ mdm [command] [options]

For a full list of available command line options, please execute mdm --help.

###1. mdm deploy

The deploy command is used to deploy changes you have made to a remote server.

It performs the following operations:

1. Opens an SSH connection to the remote server.
2. Updates the project source via Git.
3. Cleans old builds (specify how many to keep using the buildsToKeep configuration option).
4. Creates a new build directory.
5. Uses meteor or mrt (if you're using Meteorite) to bundle the latest source into a tarball.
6. Extracts the tarball into the latest build directory.
7. Resets current symbolic link to latest build directory.
8. Restarts the Node.js process associated with the project.

###2. mdm rollback

The rollback command is used to roll back an erroneous deployment.

It performs the following operations:

1. Opens an SSH connection to the remote server.
2. Resets the current symbolic link to the second most recent build directory
3. Restarts the Node.js process associated with the project.

###3. mdm generate

The generate command is used to create a sample deploy.json file in the current working directory. You should customise this file to suit your requirements.

####Sample Deployment Configuration

You can find a sample deploy.json file on GitHub: https://github.com/chriswessels/meteor-deployment-manager/blob/master/lib/sample_deploy.json

###4. mdm start

The start command is used to start the instance of Node.js associated with your application (via the Upstart script).

###5. mdm stop

The stop command is used to stop the instance of Node.js associated with your application (via the Upstart script).

###6. mdm restart

The restart command is used to restart the instance of Node.js associated with your application (via the Upstart script).

##Installation

MDM is installed using the Node Package Manager command line tool. MDM should be installed with the global flag (-g) to ensure that it is available within any Meteor application directory you might want to deploy.

Install MDM with the following command:

$ npm install -g meteor-deployment-manager

##Project and server requirements

MDM assumes that your project and server set up conforms to a set of requirements:

1. You are using Git as a version control system.
2. You use Upstart to manage system services on your server.
3. You have Node.js, Meteor and Meteorite installed on your server.
4. Your project source directory (see below) should be a Git repository with an origin remote.

###Server directory structure

app_root # This is specified in deploy.json as deploymentDirectory.
app_root/source # This directory contains the source code for your project.
app_root/working # This directory is used as a bundling directory.
app_root/builds # This directory contains the project builds made by MDM.
app_root/builds/timestamp # These directories contain the extracted bundle tarball.
app_root/builds/current # This is a symbolic link to the current build directory.
