[3.6] ResourceQuota controller observed making excessive LIST calls at scale
Last modified: 2017-08-16 15:51 EDT
Description of problem:
For all resources other than Pod or PersistentVolumeClaim, the quota controller is making a LIST call per namespace to determine current usage counts. This can cause quota recalculation to take an extended period of time. Secret, ConfigMap, ReplicationControllers, Services, and ResourceQuota quota items should have usage reconciled via a shared informer.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1. oc create quota quota --hard=services=10,secrets=10
quota controller should not make LIST calls per namespace when doing recalculation.
quota controller calculates usage from shared informer.
