Kubereboot/Kured: Kubernetes Reboot Daemon

Insert the "No god no" meme here - you really shouldn't be updating nodes in place and thus shouldn't be restarting nodes.

I'm aware bare metal exists and it's not always practical to just provision more servers, yet I think for most workloads you're not getting the benefit of Kubernetes if you have say 3 servers and lose 1/3 of your capacity to do software updates.

Almost 3000 lines of code for automating draining nodes and rebooting it. And it requires that another component has already queued up an update that requires a reboot.

Looking at the issues, people try to shoehorn a thousand unique behaviours into a general purpose tool, just to avoid a bit of old school sysadmin-ing. There's a guy wanting to change TZ of the running cluster, and want "Kured" to support that use case so it's only updated during night - in an ever changing TZ.

I like it. K8s should be more opiniated about this.

Whats also missing is rebalancing of pods. Rescheduler
