How to configure mongodb with nodered on bluemix?

Hi Folks!
I want to store the data on IBM bluemix using node-red, but i don't know how to set the configuration of the mongodb node!
I searched the internet and i find that there were a service called "mongolab" that you should add to your organization to be able to use monogodb, but i searched the mongolab service and i did not find it. Is there a way to configure and use mongodb database on nodered? A Node-RED node to save data in a MongoDB database.

Thanks
