Setting Up an In-tree VMware vSphere Cloud Provider

To set up the in-tree VMware vSphere cloud provider, follow these steps while creating the vSphere cluster in Rancher:

Set Cloud Provider option to Custom or Custom (In-Tree).
Click on Edit as YAML
Insert the following structure to the pre-populated cluster YAML. This structure must be placed under rancher_kubernetes_engine_config. Note that the name must be set to vsphere.
```
 rancher_kubernetes_engine_config:
   cloud_provider:
       name: vsphere
       vsphereCloudProvider:
           [Insert provider configuration]
```

Rancher uses RKE (the Rancher Kubernetes Engine) to provision Kubernetes clusters. Refer to the vSphere configuration reference in the RKE documentation for details about the properties of the vsphereCloudProvider directive.
