There is no plugin for podAffinity violations

[tuxillo]

Is your feature request related to a problem? Please describe.

I think it is a problem because, as far as I know, there is no way of rescheduling pods that are in violation of podAffinity.

Describe the solution you'd like

Make a plugin available that deals with this, right? 🥲

Describe alternatives you've considered
Right now I'm manually doing rollout in deployments so that the scheduling is right, for example after ugprades.

What version of descheduler are you using?

descheduler version:
latest
Additional context

Issue #1286 was closed as "Not planned" but feedback was provided and I think it's a feature that's pretty much needed.

Any news?

Hi @tuxillo, sorry but unfortunately we don't have much bandwidth for adding new plugins at this time. The descheduling framework refactor is meant to make it easier for anyone to develop their own plugins. The existing plugin code should serve as a guide, but we hope to publish a more generic developer guide in the future.

@damemi thanks for the update. No worries! I was wondering if this plugin was missing for any particular reason. I might give it a try at implementing it but, should I wait for the refactor you're mentioning?

[damemi]

@tuxillo please feel free to implement it and open a PR if you'd like! the refactor is done already. Ideally, the goal of this was to make it so you don't even need to contribute the plugin code here if you don't want to and could just build your own descheduler with your plugin imported.
