Node Feature Discovery

When you enable the Node Feature Discovery cluster add-on, you can pass the following key/value pairs as arguments.

Configuration Arguments Common to all Cluster Add-ons
Key (API and CLI) Key's Display Name (Console) Description Required/Optional Default Value Example Value
affinity affinity

A group of affinity scheduling rules.

JSON format in plain text or Base64 encoded.

Not used by:
  • Nvidia GPU Operator
Possible equivalents:
  • Node Feature Discovery, use master.affinity
  • NVIDIA Network Operator, use operator.affinity
  • CSI Driver SMB, use contoller.affinity
 Optional null null
nodeSelectors node selectors

You can use node selectors and node labels to control the worker nodes on which add-on pods run.

For a pod to run on a node, the pod's node selector must have the same key/value as the node's label.

Set nodeSelectors to a key/value pair that matches both the pod's node selector, and the worker node's label.

JSON format in plain text or Base64 encoded.

Not used by:
  • NVIDIA GPU Operator
  • CSI Driver SMB
Possible equivalents:
  • Node Feature Discovery, use worker.nodeSelector
  • NVIDIA Network Operator, use operator.nodeSelectors
 Optional null {"foo":"bar", "foo2": "bar2"}

The pod will only run on nodes that have the foo=bar or foo2=bar2 label.
numOfReplicas numOfReplicas The number of replicas of the add-on deployment.
Not used by:
  • AMD GPU Plugin
  • NVIDIA GPU Operator
  • NVIDIA Network Operator
  • CSI Driver SMB
Possible equivalents:
  • CoreDNS, use nodesPerReplica
  • Node Feature Discovery, use master.replicaCount
 Required 1

Creates one replica of the add-on deployment per cluster.

 2

Creates two replicas of the add-on deployment per cluster.
rollingUpdate rollingUpdate

Controls the desired behavior of rolling update by maxSurge and maxUnavailable.

JSON format in plain text or Base64 encoded.

Not used by:
  • Node Feature Discovery
  • NVIDIA Network Operator
  • CSI Driver SMB
Possible equivalents:
  • NVIDIA GPU Operator, use daemonsets.rollingUpdate.maxUnavailable
 Optional null null
tolerations tolerations

You can use taints and tolerations to control the worker nodes on which add-on pods run.

For a pod to run on a node that has a taint, the pod must have a corresponding toleration.

Set tolerations to a key/value pair that matches both the pod's toleration, and the worker node's taint.

JSON format in plain text or Base64 encoded.

Possible equivalents:
  • Node Feature Discovery, use master.tolerations and/or worker.tolerations
  • NVIDIA GPU Operator, use daemonsets.tolerations
  • NVIDIA Network Operator, use operator.tolerations
  • CSI Driver SMB, use controller.tolerations
 Optional null [{"key":"tolerationKeyFoo", "value":"tolerationValBar", "effect":"noSchedule", "operator":"exists"}]

Only pods that have this toleration can run on worker nodes that have the tolerationKeyFoo=tolerationValBar:noSchedule taint.
topologySpreadConstraints topologySpreadConstraints

How to spread matching pods among the given topology.

JSON format in plain text or Base64 encoded.

Not used by:
  • Node Feature Discovery
  • NVIDIA GPU Operator
  • NVIDIA Network Operator
  • CSI Driver SMB
 Optional null null
