Learn how to register your VMware environment for the NetApp Kubernetes Service (NKS) so that you can use NKS to create Kubernetes clusters on VMware.
|The ability to create VMware clusters with NKS is currently in pre-release. This feature is not GA (Generally Available).|
You will need an NKS account. If you don’t have one already, you can sign up for a free 30-day trial with no credit card required at https://nks.netapp.io.
VMware Virtual Distributed Switch installed.
DHCP on the VM network.
A defined resource pool.
Your Registration Machine Environment
You must have the NKS Registrator command-line tool installed and configured.
Download the binary:
Rename the binary to
nks-register and move it to the directory where you wish to run it.
Make the binary executable:
chmod +x nks-register_darwin
chmod 755 nks-register_linux
To verify the installation, use the command:
If the binary is installed and running correctly, this returns help information about the program.
Additional registration machine environment requirements:
Create an NKS API token
In order to register your VMware environment with NKS, you will need an NKS API token. You can use an existing NKS API token if you have one.
To create a new API token:
Register or log in at NKS.
Click your profile avatar in the top right corner and select
In the API Tokens section, click Add Token.
Copy the token and save it somewhere safe. This is your only chance to view your API token. The token cannot be displayed after you leave or reload the page.
From the command line, invoke the NKS Registrator command-line utility. You have several possible options for registering in NKS:
FlexPod: Register NetApp FlexPod as a region in NKS (interactive mode).
HCI: Register NetApp HCI as a region in NKS (interactive mode).
vSphere: Register generic vSphere as a region in NKS (interactive mode).
unregister: Remove any FlexPod, HCI or generic VMware region from NKS and delete associated on-premise resources.
create-configuration: Collect configuration values from vSphere and user input and write to a config file.
from-config: Register a region in NKS using an existing configuration file.
help: Help information for any command.
Please note that commands are case-sensitive.
You can view these options at any time by using the command:
In most cases, you will want to use
vSphere to register your VMware environment:
To begin, you will need to log in to vCenter. Enter your information at the prompts:
Your vCenter URL.
Your vCenter username.
Your vCenter password.
Next, you will be presented with a series of menus. Use your arrow key to navigate through the choices, and click Enter to select:
Your vCenter resource pool. Use the arrow key to select NKS Pool from the list.
Your vCenter datastore.
Your vCenter Management Network. If you are unsure, choose VM_Network.
Your vCenter Storage Network. If you are unsure, choose iSCSI—B.
Enter a name for your new region. This name should be unique to your system, and specific enough to be easily identifiable when you need to select it to provision an NKS cluster.
Enter the NKS API URL https://api.nks.netapp.io.
Paste in your NKS API token.
Use the arrow key to select the NKS organization you want to use for provisioning clusters on VMware.
Optional: If you want to set up Element storage for your region, select it here.
This completes the information collection.
The registration process will begin, and you will see a message that the Bootstrap VM output will be dumped to a local file. Make a note of the bootstrap output file name.
The progress meter will count up to 100, at which point the registration process is complete, and you are returned to the command line prompt. You can read the bootstrap output file to verify that registration completed successfully.
You can now create a NetApp HCI cluster in your VMware environment. Click here for step-by-step instructions.
