Open Stack

Hi Johnny (or Richard?)

So the problem here doesn't seem directly related to autoscaling with ceilometer.

Rather it results from the way heat only validates credentials for the created
stack in certain circumstances (specifically if a ScalingPolicy, HARestarter, or
WaitConditionHandle is contained in the teamplate, see [1])

So I think you've discovered that you can invoke heat stack-create without creds
for simple templates, but then you're tripping over the lack of credentials when
you attempt to use more advanced templates.

Can you ensure that the OS_* env vars are set *before* invoking 'heat stack-create'?

e.g. on devstack:

  $ . devstack/openrc admin admin

Cheers,
Eoghan
