Configure Drivers

VDO currently supports configuring CloudProvider (CPI) and StorageProvider(CSI)

Run the following command to provide VDO with the necessary configuration enabling VDO to install/configure vSphere CPI and CSI drivers

vdoctl configure drivers

CloudProvider

CloudProvider is an optional configuration. you can choose to skip this if you are not looking to install Kubernetes vSphere Cloud Provider

If you want to install Kubernetes vSphere Cloud Provider, you will be taken through a series of configuration options to configure CPI

  • IP address of vcenter
  • Secure Connection - If you choose to establish a secure connection to vcenter, you need to provide a ssl thumbprint
  • Login credentials for vcenter
  • Datacenter(s) - you can provide a comma separated list of datacenters

Pre-requisites for installing CPI can be found here.

Please provide the vcenter IP for configuring CloudProvider 
VC IP 10.10.10.10
Do you want to establish a secure connection? (Y/N) y
SSL Thumbprint █

Please provide the credentials for configuring CloudProvider
Username user
Password *******
Datacenter(s) dc0, dc1

Upon successful validation of the above information, you will be asked for the next set of configuration. At this point, you can choose to configure another VC, if you want CPI to work with multiple vcenters

Do you want to configure another vcenter for CloudProvider? (Y/N) y

VC IP 11.11.11.11
Do you want to establish a secure connection? (Y/N) y
SSL Thumbprint █

Please provide the credentials for configuring CloudProvider
Username user
Password *******
Datacenter(s) dc2, dc3

Once done you can choose to configure zones/regions if required. Please note, the tags for zone/regions need to be available in vcenter. Please refer CPI documentation on how to configure zones/regions

Do you want to configure zones/regions for CloudProvider? (Y/N) y
Zones zonea
Regions region1█
StorageProvider

Configuration of CSI requires you to enter the configuration of vcenter with which you wish CSI to work

If you have configured more than once vcenter for CPI, you would be asked to choose one of the vcenter's to configure CSI.

If not, we will use the same vcenter ip address for CSI and CPI drivers

? Please select vcenter for configuring StorageProvider: 
+   
  ▸ 10.10.10.10
    11.11.11.11

As before with CPI, you will also need to provide the credentials to connect to vcenter and the datacenter

Please provide the credentials for configuring StorageProvider
Username user
Password *******
Datacenter(s) Datacenter

You can then provide custom Kubelet Path if required as vSphere CSI driver deployment provides an option to specify the path to kubelet.

Do you wish to provide custom kubelet Path? (Y/N) y
Kubelet Path /var/data/kubelet

Additionally, you can choose to configure Net Permissions for File volumes

Do you wish to configure File Volumes? (Y/N) y
Do you wish to configure vSAN DataStores for File Volumes (Y/N) y
vSAN DataStore Url(s) //ds:///vmfs/volumes/11111
Do you wish to configure Net permissions for File Volumes (Y/N) y
File Volumes IP Subnet 10.20.20.0/24
Use the arrow keys to navigate: ↓ ↑ → ← 
? Permissions type for File Volumes: 
+   
  ▸ READ_ONLY
    READ_WRITE
Allow Root Access? (Y/N) y█

To get more info on Net Permissions, please refer CSI document

Note: For CSI driver version >= 2.5, that does not rely on vSphere Cloud Provider in order to obtain the VM node uuid, VDO updates the internal-feature-states.csi.vsphere.vmware.com configmap to set the "use-csinode-id" key as true.

This completes VDO configuration. You can check the status of drivers using vdoctl status command.
