This is a custom OpenShift cartridge providing MongoDB > 3.0.3.

Because the standard OpenShift MongoDB cartridge is stuck at 2.4.

When you need a quick and unsofisticated solution to run your application with the latest MongoDB version.

To install this cartridge in your existing OpenShift application, go to "See the list of cartridges you can add", paste the URL below in "Install your own cartridge" textbox at the bottom of the page and click "Next".

Then you can use MONGODB_URL environment variable to connect from an application running in the main web cartridge.

To keep things flexible, the connection string stored in MONGODB_URL ends with / and does not include a database name. Use your application logic to name/create your database(s) as needed.

For instance, here's how you'd do it in a Node.js application using Mongoose ODM:

var mongoose = require('mongoose');
...
// Mongoose will create database_name if necessary
mongoose.connect(process.env.MONGODB_URL + 'database_name', { db: { nativeParser: true } });

• Can't guarantee this cartridge is production-ready. Some people use it though (on their own responsibility).
• This is a lean cartridge. To save space, just mongod is installed. No client libraries, no mongo console. If you need external access to your data, use rhc port-forward.
• By default, the underlying MongoDB instance will accept unauthenticated access, which should be fine for most typical usage scenarios. See the discussion here for more info.
• Can't think of a way to make this cartridge auto-updatable. There's nothing like semver.io for MongoDB. For now we'll just have to use mongodump, destroy the cartridge, install the new version, then do a mongorestore.
• Don't hesitate to make a pull-request with an updated version in this file if you notice this cartridge version is behind the latest stable official MongoDB linux binary.

Q: I'm getting the error Cannot download, must be smaller than 20480 bytes while trying to deploy the cartridge to OpenShift. What am I doing wrong?

A: You're probably trying to use the URL https://github.com/icflorescu/openshift-cartridge-mongodb instead of http://cartreflect-claytondev.rhcloud.com/github/icflorescu/openshift-cartridge-mongodb. A common mistake for people not paying sufficient attention while trying to use a custom cartridge for the first time.

Since you're here, chances are you might also be interested in this custom Node.js cartridge.
