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

1. Set Cloud Provider option to Custom or Custom (In-Tree).

   

2. Click on Edit as YAML

3. 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.
