We have a DaemonSet that requires different amount of resources depending on node capacity. In clusters with vastly different node sizes, this creates a problem - either on some nodes our Pods will not have enough resources, or they will have too much (hence wasting cluster resources), or both. Is …

Thanks, @thockin . I am curious… if someone wanted to do something like this, is there an elegant-enough way to do it without duplicating DaemonSetController? E.g., using the upcoming in-place Pod resize feature? In-Place Update of Pod Resources · Issue #1287 · kubernetes/enhancements · GitHub

The controller just creates a daemonset for each label key-value, based on the template, but varies b…
