# 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"
vsphere_resource_pool: "K8s-Pool"
```

## 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.
