kubelet evicts resources when observing disk pressure #39

Given todays conversation, perhaps we could have a default policy of: "should pro-actively reclaim related resource to maintain node stability by deleting images, logs, and evicting pods." with the potential of firing an administrator controlled script which could also apply to other resource dimensions. /cc @nqn |
I think that is feature creep. The goal is disk. Other resource On Monday, July 25, 2016, Timothy St. Clair notifications@github.com

Description
As a cluster operator, I want the kubelet to monitor local disk usage and respond accordingly to maintain node stability. If the kubelet observes available disk and/or inodes (rootfs or imagefs) are under pressure, the kubelet should pro-actively reclaim related resource to maintain node stability by deleting images, logs, and evicting pods.

Coding
and sometimes http://github.com/kubernetes/contrib, or other repos.
check that the code matches the proposed feature and design, and that everything is done, and that there is adequate
testing. They won't do detailed code review: that already happened when your PRs were reviewed.
When that is done, you can check this box and the reviewer will apply the "code-complete" label.
