+# vSphere cloud provider
+
+Kubespray can be deployed with vSphere as Cloud provider. This feature supports
+- Volumes
+- Persistent Volumes
+- Storage Classes and provisioning of volumes.
+- vSphere Storage Policy Based Management for Containers orchestrated by Kubernetes.
+
+## Prerequisites
+
+You need at first to configure you vSphere environement by following the [official documentation](https://kubernetes.io/docs/getting-started-guides/vsphere/#vsphere-cloud-provider).
+
+After this step you should have:
+- UUID activated for each VM where Kubernetes will be deployed
+- A vSphere account with required privileges
+
+## Kubespray configuration
+
+Fist you must define the cloud provider in `inventory/group_vars/all.yml` and set it to `vsphere`.
+```yml
+cloud_provider: vsphere
+```
+
+Then, in the same file, you need to declare your vCenter credential following the description bellow.

+Example configuration
+```yml
+vsphere_vcenter_ip: "myvcenter.domain.com"
+vsphere_vcenter_port: 443
+vsphere_insecure: 1
+vsphere_user: "k8s@vsphere.local"
+vsphere_password: "K8s_admin"
+vsphere_datacenter: "DATACENTER_name"
+vsphere_datastore: "DATASTORE_name"
+vsphere_working_dir: "Docker_hosts"
+vsphere_scsi_controller_type: "pvscsi"
+```
+
+## Deployment
+
+Once the configuration is set, you can execute the playbook again to apply the new configuration
+```
+cd kubespray
+ansible-playbook -i inventory/inventory.cfg -b -v cluster.yml
+```
+
+You'll find some usefull examples [here](https://github.com/kubernetes/kubernetes/tree/master/examples/volumes/vsphere) to test your configuration.
