Comment 0 for bug 1743509

We have a bug during the creation of a trove cluster.

The taskmanager can't get ip address of cluster instances.

Everything was tested from master(trove, trove-pythonclient)

trove --debug cluster-create cluster mariadb 10.1 --instance "flavor=101,volume=5,nic='net-id=09cd3332-146b-430f-b973-2d1cf204288d'" --instance "flavor=101,volume=5,nic='net-id=09cd3332-146b-430f-b973-2d1cf204288d'" --instance "flavor=101,volume=5,nic='net-id=09cd3332-146b-430f-b973-2d1cf204288d'"

cat /var/log/kolla/trove/trove-taskmanager.log
