@mikestef9 Is the value that EKS uses for this flag documented anywhere?

You can check it in Cloudwatch when you enable the control plane logging. In my EKS 1.21 cluster it's: --terminated-pod-gc-threshold="12500"

That's long ago deleted, though I'll take that as its set to the default.

Another flag that should be configurable is --horizontal-pod-autoscaler-tolerance. The default value is 0.1, or 10%, but there are use cases to make the value smaller (more sensitive, more responsive) or larger.

Just to add to the list of parameters that we'd like configurable. --concurrent-horizontal-pod-autoscaler-syncs which is new in K8s 1.26.

Is there like any reason to not allow overriding this --terminated-pod-gc-threshold default value? it's really a pain to have to clean up those terminated pods manually or having a cronjob to do it...
