ObservabilityAgent

When you enable the ObservabilityAgent 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.

 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.

 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.

For AMD GPU Plugin, not used.

For CoreDNS, use nodesPerReplica instead.

 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.

 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.

 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.

 Optional null null
