metrics-adapter not installed by default with helm chart and not clear how to install

[kutsyk]

I've installed Karmada using helm, later I've added descheduler to it as recommended, but I can't find out how to install metrics-adapater, I don't want to copy/create manually deployment as I believe there is different way.

This command did nothing:

helm upgrade --install karmada -n karmada-system --create-namespace --dependency-update --cleanup-on-fail ./charts/karmada --set components={"metrics-adapter"}

Can you try it this way?

--set components={"metricsAdapter"}

Hi @chaunceyjiang , it worked, thanks. Although I'm not sure if it works as expected, here is what I see in logs:

custom.metrics.k8s.io not found in cluster(...)

Is this expected?

I can't quite figure out from the documentation what for and how to use this component.

Feels like this log is not expected, at least it shouldn't be dumped so frequently.
This issue is tracked by #4792.
