Thanks for your answer, but actually I did give a look on we retail, and It was exactly what I was thinking, It was the core/wcm/components/v2/page that was necessary, also you need a folder cloudconfigs under you folder conf/project/settings in order to create a launch config.
What I did not like to know is that that is not documented, at least if It is It is really hard to find cause I didn't.
Thanks any way.
