Installation

If you want to use Nutanix Node Driver, you need add it in order to start using them to create node templates and eventually node pools for your Kubernetes cluster.

1. From the Home view, choose Cluster Management > Drivers in the navigation bar. From the Drivers page, select the Node Drivers tab.

2. Click Add Node Driver.

   • Download URL: https://github.com/nutanix/docker-machine/releases/download/v3.6.0/docker-machine-driver-nutanix
   • Custom UI URL: https://nutanix.github.io/rancher-ui-driver/v3.6.0/component.js
   • Checksum: ``
   • Whitelist Domains: nutanix.github.io

   whitelist is mandatory and need to be changed if you relocate the UI driver

Project support

Starting v3.3.0 the Rancher Node driver implements Nutanix Project support. The prerequisite needed to be able to use the Rancher Node Driver is the following:

• Target cluster and network available in the Project
• Role with the following recommended permission:
  • VM Full Access
  • Cluster View Access
  • Image View Only

Development

Build Instructions

build linux/amd64 binary => make build local binary => make local

History
