Kubernetes OpenStack integration

Trying to make integration work, but have some problems. When --cloudprovider=openstack, kube-apiserver is crashing immediately after start with this message All needed configuration is provided via cloud.conf and loaded via --cloudconfig=/etc/cloud.conf. Does anyone have success with such setup?

Error message:

Allright, region in mandatory option. When it's empty code will fail. You must specify it, even if your OpenStack doesn't uses regions. The biggest issue is that code itself don't checking parameters specified by user and thus cannot inform what you are doing wrong.

Can you paste your cloud.conf here ? Looks like your openstack cloud did not get instantiated.
