# 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_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.
