This section describes how to enable the vSphere cloud provider. You will need to use the cloud_provider directive in the cluster YAML file.

The vSphere Cloud Provider interacts with VMware infrastructure (vCenter or standalone ESXi server) to provision and manage storage for persistent volumes in a Kubernetes cluster.

When provisioning Kubernetes using RKE CLI or using RKE clusters in Rancher, the vSphere Cloud Provider can be enabled by configuring the cloud_provider directive in the cluster YAML file.

• Configuration: For details on vSphere configuration in RKE, refer to the configuration reference.
• Troubleshooting: For guidance on troubleshooting a cluster with the vSphere cloud provider enabled, refer to the troubleshooting section.
• Storage: If you are setting up storage, see the official vSphere documentation on storage for Kubernetes, or the official Kubernetes documentation on persistent volumes. If you are using Rancher, refer to the Rancher documentation on provisioning storage in vSphere.
• For Rancher users: Refer to the Rancher documentation on creating vSphere Kubernetes clusters and provisioning storage.

Prerequisites

• Credentials: You’ll need to have credentials of a vCenter/ESXi user account with privileges allowing the cloud provider to interact with the vSphere infrastructure to provision storage. Refer to this document to create and assign a role with the required permissions in vCenter.
• VMware Tools must be running in the Guest OS for all nodes in the cluster.
• Disk UUIDs: All nodes must be configured with disk UUIDs. This is required so that attached VMDKs present a consistent UUID to the VM, allowing the disk to be mounted properly. See the section on enabling disk UUIDs.

Enabling the vSphere Provider with the RKE CLI

To enable the vSphere Cloud Provider in the cluster, you must add the top-level cloud_provider directive to the cluster configuration file, set the name property to vsphere and add the vsphereCloudProvider directive containing the configuration matching your infrastructure. See the configuration reference for the gory details.
