Pods do not get evicted while logs say "evicting pods from node" about descheduler

[concaf]

Interesting, this works fine for v1.8.4 -

$ kubectl version
Client Version: version.Info{Major:"1", Minor:"8+", GitVersion:"v1.8.4-dirty", GitCommit:"9befc2b8928a9426501d3bf62f72849d5cbcd5a3", GitTreeState:"dirty", BuildDate:"2017-11-25T12:04:44Z", GoVersion:"go1.8.3", Compiler:"gc", Platform:"linux/amd64"}
Server Version: version.Info{Major:"1", Minor:"8+", GitVersion:"v1.8.4-dirty", GitCommit:"9befc2b8928a9426501d3bf62f72849d5cbcd5a3", GitTreeState:"dirty", BuildDate:"2017-11-25T11:54:10Z", GoVersion:"go1.8.3", Compiler:"gc", Platform:"linux/amd64"}

So, if I understood correctly,

• any node below the percentages in nodeResourceUtilizationThresholds.thresholds is considered underutilized
• any node above the percentages in nodeResourceUtilizationThresholds.targetThresholds is considered overutilized
• any node below the above 2 range is considered appropriately utilized by the descheduler and not taken into consideration

Your understanding is correct.

         thresholds:  # any node below the following percentages is considered underutilized
           "cpu" : 40
           "memory": 40
           "pods": 40
         targetThresholds: # any node above the following percentages is considered overutilized
           "cpu" : 30
           "memory": 2
           "pods": 1

This is weird/incorrect as the idea is to have targetThresholds >= thresholds.

@aveshagarwal yep, was just playing around with the policy file.

This did not work for me when I deployed a cluster from Kubernetes master the other day, but when I switched to v1.8.4, the descheduler did evict the pods. Is this expected behavior, which versions does the descheduler support today?
