[Bug 1439696] [NEW] Referencing a network ID for the first time from Heat would fail

  Thread Previous • Date Previous • • Thread Next 
Public bug reported:

Creating a stack with heat that creates a network and then referencing that network ID to a consumer (in this case lb-healthmonitor) would result in a 404 for that ID.
This happens only at the first attempt to do so. Deleting the heat stack and recreating it using the same template would result in a success so it does not look like an issue originating from heat. Later operations either by neutron or Heat would succeed and the only way to reproduce this specific issue is to unstack and re-stack.
