GPU Node Label

Overview

Each node that provides GPUs must be labeled correctly.

NOTE - these configurations should be completed on a Kubernetes control plane node

Label Template

• Use this label template in the kubectl label command in the subsequent Label Appliction sub-section below

NOTE - this section is information only. The template displayed will be used in a subsequent sections.

nexqloud.network/capabilities.gpu.vendor.<vendor name>.model.<model name>=true

Label Application

Template

NOTE - if you are unsure of the <node-name> to be used in this command - issue kubectl get nodes from one of your Kubernetes control plane nodes to obtain via the NAME column of this command output

kubectl label node <node-name> <label>

Example

NOTE - issue this command/label application for all nodes hosting GPU resources

kubectl label node node1 nexqloud.network/capabilities.gpu.vendor.nvidia.model.a4000=true

Expected Output using Example

root@node1:~/provider# kubectl label node node1 nexqloud.network/capabilities.gpu.vendor.nvidia.model.a4000=true

node/node1 labeled

Verification of Node Labels

• Replace <node-name> with the node of interest

kubectl describe node <node-name> | grep -A10 Labels

Expected Output using Example

kubectl describe node node2 | grep -A10 Labels

Labels:             nexqloud.network/capabilities.gpu.vendor.nvidia.model.a4000=true
