|
||
|
|
|

|
|
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
|
||
|
|
```
|
||
|
|
|
||

|
||
|
|
vsphere_vcenter_port: 443
|
||
|
|
vsphere_insecure: 1
|

## Deployment
|
||
|

|
|
```
|
||
|
|
|

You'll find some usefull examples [here](https://github.com/kubernetes/kubernetes/tree/master/examples/volumes/vsphere) to test your configuration.
