How to use google cloud storage as Laravel 5 filesystem?

I'm developing an application that lets my users upload files, and I've made it works with "local" disk using filesystem feature, but now I want to migrate and use google Google Cloud Storage for it.

It has been a lot difficult to find some useful information. In the docs there is an "example" for work with dropbox, but it's not complete. It doesn't shows how to config drivers and disk, so it isn't clear enough for me.

I would like to know what to do, since I have no idea from now.

I've just used this tutorial http://ift.tt/1wiHK8c and it's working for local, so I really need to migrate to google cloud storage, and only that. I'm using openshift and I feel comfortable about it.

Could you please help me to know what should I configure filesystem to be used as I need?

Thank you
