Open Stack

Looking for guidance on fixing the following error (end of email) that we are seeing when ‘deploying’ a very simple murano package/app on a Murano deployment WITHOUT the second rabbit server for murano-agent.

So we have a NEWTON-version of MURANO integrated into our OpenStack solution.

We have modified murano.conf:
     …
     # Disallow the use of murano-agent (boolean value)
     disable_murano_agent = true
     …

We are NOT even running the second rabbit server for communication with murano-agent.

With a very simple murano package/app, that basically just does a “ $.instance.deploy() “ in its deploy method of its main class.
( NOTE:  I have tested this murano package/app on other Murano setups and it works … although those Murano setups had murano-agent and second rabbit enabled. )

And we get the following traceback error (see end of email).

Questions:
    - I believe this is a valid configuration
    - but does anyone actually run Murano in this type of setup ?   I am guessing not many … so is this an upstream murano bug that I am seeing ? … that nobody else sees because basically no one runs in this mode ?

    - if this should work, and works in other setups,
      … any guidance on how to resolve / debug what is going on here ?


Thanks in advance,
Greg.
