 The mechanism for supporting cloud providers is currently in transition:  the original method of implementing cloud provider-specific functionality within the main kubernetes tree (here) is no longer advised; however, the proposed solution is still in development.
  
 #### Guidance for potential cloud providers: 
-* Support for cloud providers is currently in a state of flux. Background information on motivation and the proposal for improving is in the github [proposal](https://git.k8s.io/community/contributors/design-proposals/cloud-provider-refactoring.md).

 * In support of this plan, a new cloud-controller-manager binary was added in 1.6. This was the first of several steps (see the proposal for more information). 
 * Attempts to contribute new cloud providers or (to a lesser extent) persistent volumes to the core repo will likely meet with some pushback from reviewers/approvers. 
 * It is understood that this is an unfortunate situation in which 'the old way is no longer supported but the new way is not ready yet', but the initial path is unsustainable, and contributors are encouraged to participate in the implementation of the proposed long-term solution, as there is risk that PRs for new cloud providers here will not be approved.

 * 1.6 added a new cloud-controller-manager binary that may be used for testing the new out-of-core cloudprovider flow.
 * Setting cloud-provider=external allows for creation of a separate controller-manager binary
