I am asking a question on behalf of nico1129, but it's a common question so it is worth adding here.
[edited]
I did an installation of OpenStack (with heat) using devstack.
I then tried creating the template "AutoScalingMuliAZSample.template" but got an error:
"Error: Resource create failed: WaitConditionTimeout: 0 of 1 received" in loadbalancer
Do you have any suggestion on solving the problem?
