Hey folks,

Designate is deployed, all containers are running fine, logs after deployment - http://paste.openstack.org/show/794143/

Bind9 container logs are fine as well - http://paste.openstack.org/show/794144/

Then I opened designate-worker and tried to update pool manually - http://paste.openstack.org/show/794145/ ; Pool Configuration is totally different to the one which is specified in pools.yaml file. Once you run update command - nothing is changed so it is looking for a pool which is not in pool config. Thus, not sure if its related to designate itself or k-a Update conf pool task is not working as it should.

Regards
