Option for LowNodeUtilization and HighNodeUtilization for node regex name filtering about descheduler

[damemi]

Hi @Fran-Rg, have you tried setting a node selector on the evictor? https://github.com/kubernetes-sigs/descheduler?tab=readme-ov-file#evictor-plugin-configuration-default-evictor wondering if that's sufficient or you hit problems with it

[Fran-Rg]

I didn't know but unfortunately without wildcards support or negative selection then it would still not work in my case. Also it doesn't look specified but I'll assume this node selector is done via label key=value, right?

NodeSelectors are just like label selectors afaik, which do have negative selection and set-based syntax: https://kubernetes.io/docs/concepts/overview/working-with-objects/labels/#label-selectors

Not sure about wildcard, but have you considered using node labels instead of relying on node name? That's generally the appropriate approach for something like this
