Description Derek Carr 2017-07-19 23:30:49 UTC

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):


How reproducible:
always

Steps to Reproduce:
1. oc create quota quota --hard=services=10,secrets=10
2.
3.

Actual results:
quota controller should not make LIST calls per namespace when doing recalculation.

Expected results:
quota controller calculates usage from shared informer.

Additional info:
none
