re: Meet a Kubernetes Descheduler VIEW POST

I appreciate the write up but if you need a descheduler to undo what a scheduler did is that not a problem?

Not trying to sound snarky but this seems to indicate a design flaw more than anything else. One reason I'm not a fan of k8s is because of all the YAML and lack of programmability for scenarios exactly like this one. If k8s was programmable then people could write their own scheduling policies without having to undo the decisions of the default scheduler.

 

For most, this behaviour is not a problem. Descheduler is not used that much meaning that you can live without it just fine. But, if you find there is a missing piece as I did for my particular environment, it is an "easy fix". The whole point of yaml in k8s is to programmatically describe the behavior of your app. You can use Helm to make templates and easy installations. k8s is complex and I'm not denying it, but for me, it works really well. How much experience do you have with k8s, did you tried it, using it already or just considering?

 

Yes. I used it at several workplaces and at one place we were even making a custom distribution.
