Limit OpenStack discovery with white list #241

Closed hmorikaw closed 5 years ago

hmorikaw commented 6 years ago

Describe the solution you'd like [A clear and concise description of what you want to happen.]

The OpenStack discoverer sync cycle spend too long when OpenStack cluster has too many projects. So, I'd like to limit sync projects by white list.

In my cluster, which has about 3900 projects, one sync cycle spends about 30 min. So, OpenStack LBaaS operations don't sync instantly. 

$ kubectl logs openstack-discoverer-5556b6dcbc-ptj6n -n gimbal-discovery | grep 'dreco-001/openstack-626c5bf1-3cf8-438a-b6a1-e20419126eee'
