Hi mohamed,
The proper google-group to open such a discussion (as it's a compute engine thing), would be
this one.
In any case, we normally expect a bit more research and details in the questions put here. While we're more than happy to help you. But here, you're literally asking us to figure out how to use a third party product with our platform. If you have some steps done and fail at some point, we can look into those and help you. But writing a full tutorial on how to include a third party, unsupported tool on the platform, seems a bit excessive.
I would suggest you try looking into centos7, and see what can and cannot be done. When you hit a hurdle, feel free to post about it either on serverfault, or on the gce discussion list.
Cheers!
