How to set tolerations for KEDA

[batbattur]

How do I set tolerations for the keda-operator and keda-operator-metrics-apiserver?

Currently I use the KEDA operator and metrics api server from the chart (without using external) as following:

    autoscaling:
      enabled: true
      scalingType: deployment
      scaledOptions:
        minReplicaCount: 1
        maxReplicaCount: 5
        pollingInterval: 20
        triggers:
        - type: selenium-grid
          metadata:
            url: "http://selenium-grid-selenium-hub.selenium:4444/graphql"
            browserName: 'chrome'
            platformName: 'linux'

However, I am unsure how to set tolerations for the keda-operator and keda-operator-metrics-apiserver?
I noticed that there are some values for KEDA in the following but nothing to set for the tolerations.

docker-selenium/charts/selenium-grid/values.yaml

Lines 1987 to 2010 in 967cb27

	# Configuration for dependency chart keda
	keda:
	# enabled: false
	# -- Specify image for KEDA components
	image:
	keda:
	registry: selenium
	repository: keda
	tag: "2.16.1-selenium-grid-20250120"
	metricsApiServer:
	registry: selenium
	repository: keda-metrics-apiserver
	tag: "2.16.1-selenium-grid-20250120"
	webhooks:
	registry: selenium
	repository: keda-admission-webhooks
	tag: "2.16.1-selenium-grid-20250120"
	# -- Annotations for KEDA resources
	additionalAnnotations:
	http:
	timeout: 60000
	# -- Enable KEDA admission webhooks component
	webhooks:
	enabled: false

If I want to set tolerations, does it mean I have to create my own external keda and set the tolerations manually?

Hi, if you are using KEDA is deployed by sub-chart KEDA in Grid chart, you can refer to KEDA chart configs https://artifacthub.io/packages/helm/kedacore/keda and add something you want to change in structure under key keda:
In default values.yaml, we only override a few values we needed, for others it will inherit from KEDA chart.

Thank you very much, that worked!
