Best pratice to deploy multiple scale sets with different image in a single cluster

[jianliang00]

I'm a beginner for ARC and I'm trying to deploy multiple scale sets in a single cluster to allow selecting different runner environment in workflow. For example, I can configure run-on to self-hosted-arc-ubuntu-22.04 for one job and self-hosted-arc-ubuntu-20.04 for another.

I tried to deploy a second scale set with the different INSTALLATION_NAME after successfully deployed the first one. But the listener pod of the sencond continue throwing an error and restarting:

2024-07-24T08:00:33Z INFO listener-app.listener Deleting message session
2024/07/24 08:00:34 Application returned an error: handling initial message failed: could not patch ephemeral runner set , patch JSON: {"spec":{"patchID":0,"replicas":null}}, error: Patch "https://10.96.0.1:443/apis/actions.github.com/v1alpha1/namespaces/arc-runners/ephemeralrunnersets/arc-ubuntu-22.04-kw5kt": Forbidden

I have no idea whether my operation is the right way to create multiple scale sets. Are there any document or discussions about how to do it?`

It's caused by the proxy and does nothing to do with the multiple scale sets
