Discussion:
This is required to make Cloud Controller Manager operational on the various clouds that Kubernetes runs on. We have already PRs for the following clouds: GCE - AWS - Azure - OpenStack - The following clouds still need to be addresses: CloudStack Mesos OVirt Photon Rackspace vSphere If anyone is interested in contributing to this effort, please ping me directly (on kubernetes slack or through email)

I will take care of the vSphere and Photon.
I will take care of the Rackspace.
Merging for OpenStack
Reposting I am trying to use my custom out-of-tree cloud provider with Kubernetes. But I noticed that kubelet calls apis like with empty for cloud provider. Digging in the code for 1.7 branch, I see that is null for cloud-providers. As a result returns empty string. As a result, ByID() methods don't work for cloud providers since is not set.
