d353cc1532 Use maxSkew in PodTopologySpread scoring as tolerance to skew 
This new approach results in better spreading for small number of pods, while still giving meaning to the maxSkew parameter.

Merge pull request #91138 from chendave/imagelocality 
Define the thresholds per the size of container images
 2020-05-31 16:17:53 -07:00
Dave Chen
42fbb1d72f Define the thresholds per the size of container images 
Given the assumption that 90% of images on dockerhub drops into this range (23~1000)MB,
this assumption is based on the container images instead of the pod.

pod might hold multiple container images, it's better to multiply the assumption by the size
of container images.
