Hi Greg,

this is yet another similar bug in another place.
Here is the fix for you: https://review.openstack.org/#/c/442198/

Also please consider using LinuxInstance class instead of LinuxMuranoInstance.
LinuxInstance doesn't try to build agent config and push it through cloud-init and thus should not
have such problems

Regards,
Stan

Hey Stan,

We tried doing the changes from https://review.openstack.org/#/c/441477/
i.e.
    changing the first couple of lines in the __init__ of AgentListener in agent_listener.py
 class AgentListener(object):
     def __init__(self, name):
-        self._enabled = False
-        if CONF.engine.disable_murano_agent:
-            return
-        self._enabled = True
+        self._enabled = not CONF.engine.disable_murano_agent
         self._results_queue = str('-execution-results-%s' % name.lower())
         self._subscriptions = {}
         self._receive_thread = None

But still get the following issue:     ??? Any suggestions ???
Greg.

Subject: Re: [openstack-dev] [Murano] Errors on $.instance.deploy() ... WHEN RUNNING WITHOUT MURANO-AGENT RABBIT

Greg,

you're right in everything you said.

This was fixed in master in https://review.openstack.org/#/c/387993/ with intent to fix tests and unblock the gate. But since those tests were introduced in Ocata the fix was not backported to Newton.
So I've just did a partial packport of the root cause fix. Here it is: https://review.openstack.org/#/c/441477/

Sincerely yours,

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.
