Thanks a lot for this PR I was not expecting this that fast! I think it's better to have the examples in it's own ovhcloud folder to ease the discovering. As it will be almost identical to OpenStack you can just copy the OpenStack folder and update the README.md with the specific OVHcloud bits?

@tormath1 Just pushed the OVHcloud version, largely copied from Openstack but with some modifications (notably on the image).

Thanks a lot - I am on vacation from tonight and for a few weeks, I'll have a look at my return (or if someone from @flatcar/flatcar-maintainers wants to review it)

[tormath1]

Maybe we can just add a note to the OVH documentation to find those information?

LGTM. Thanks! Just one question and it's good to go.
