### hostPath Volumes
Before you create a hostPath volume, you need to set up an [extra_bind]({{<baseurl>}}/rke/latest/en/config-options/services/services-extras/#extra-binds/) in your cluster configuration. This will mount the path as a volume in your kubelets, which can then be used for hostPath volumes in your workloads.
### Migrating vSphere Cloud Provider from In-tree to Out-of-tree
Kubernetes is moving away from maintaining cloud providers in-tree. vSphere has an out-of-tree cloud provider that can be used by installing the vSphere cloud provider and cloud storage plugins.
For instructions on how to migrate from the in-tree vSphere cloud provider to out-of-tree, and manage the existing VMs post migration, refer to [this page.]({{<baseurl>}}/rancher/v2.5/en/cluster-provisioning/rke-clusters/cloud-providers/vsphere/out-of-tree)

In this section, you'll learn how to set up the vSphere cloud provider for a Rancher managed RKE Kubernetes cluster in vSphere.
In this section, you'll learn how to set up a vSphere cloud provider for a Rancher managed RKE Kubernetes cluster in vSphere.
Follow these steps while creating the vSphere cluster in Rancher:
# In-tree Cloud Provider
1. Set **Cloud Provider** option to `Custom`.
To use the in-tree vSphere cloud provider, you will need to use an RKE configuration option. For details, refer to [this page.](./in-tree)
{{< img "/img/rancher/vsphere-node-driver-cloudprovider.png" "vsphere-node-driver-cloudprovider">}}
# Out-of-tree Cloud Provider
1. Click on **Edit as YAML**
1. 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`.
_Available as of v2.5.6_
```yaml
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]({{<baseurl>}}/rke/latest/en/config-options/cloud-providers/vsphere/config-reference/) for details about the properties of the `vsphereCloudProvider` directive.
To set up the out-of-tree vSphere cloud provider, you will need to install Helm charts from the Rancher marketplace. For details, refer to [this page.](./out-of-tree)
