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).

    vsphere-node-driver-cloudprovider
  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.
