# 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.
| Variable | Required | Type | Choices | Default | Comment |
|------------------------------|----------|---------|----------------------------|---------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------|
| vsphere_vcenter_ip | TRUE | string | | | IP/URL of the vCenter |
| vsphere_vcenter_port | TRUE | integer | | | Port of the vCenter API. Commonly 443 |
| vsphere_insecure | TRUE | integer | 1, 0 | | set to 1 if the host above uses a self-signed cert |
| vsphere_user | TRUE | string | | | User name for vCenter with required privileges |
| vsphere_password | TRUE | string | | | Password for vCenter |
| vsphere_datacenter | TRUE | string | | | Datacenter name to use |
| vsphere_datastore | TRUE | string | | | Datastore name to use |
| vsphere_working_dir | TRUE | string | | | Working directory from the view "VMs and template" in the vCenter where VM are placed |
| vsphere_scsi_controller_type | TRUE | string | buslogic, pvscsi, parallel | pvscsi | SCSI controller name. Commonly "pvscsi". |
| vsphere_vm_uuid | FALSE | string | | | VM Instance UUID of virtual machine that host K8s master. Can be retrieved from instanceUuid property in VmConfigInfo, or as vc.uuid in VMX file or in `/sys/class/dmi/id/product_serial` (only optional for Kubernetes <= 1.9.2) |
| vsphere_public_network | FALSE | string | | Blank | Name of the network the VMs are joined to |
| vsphere_resource_pool | FALSE | string | | Blank | Name of the Resource pool where the VMs are located (optional for Kubernetes >= 1.9.2) |
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.
