What is the way to call nested heat file from the main template, in Murano.

have you tried to call it just network.yaml (without the path)?

Still getting this error:

2016-05-03 03:49:10 — [heatclient.exc.HTTPBadRequest]: ERROR: Could not fetch remote template "network.yaml": Invalid URL scheme
2016-05-03 03:49:10 — ERROR: Could not fetch remote template "network.yaml": Invalid URL scheme

As far as I can see from the code the environment files must be placed in Resources/HotEnvironments and HOT-accessible files are under Resources/HotFiles. You can place them in some subfolder there. To reference those files you use relative path to those locations. In most cases it means file name only.

If it still doesn't help, please share your package and I'll take a look

I am still not able to get it running.
Here is my package https://drive.google.com/file/d/0B3No1UHUN3G2VW9JUDdZcEpZVjg/view?usp=sharing
Any help will be appreciated.

I'm not a Heat expert and probably just don't know that such syntax is possible. Can you point me to a documentation that says that you can put a file name as a resource type? I'm looking at http://docs.openstack.org/developer/heat/template_guide/environment.html and from what I understand you need to have one environment file that has a resource registry (that can reference other files) and use it to define new resource types. And this is the model that Murano supports. You can supply HOT app with a environment file that is going to be used for the whole stack. Also it looks like the generated UI form doesn't ask for environment file name so the only way to provide it is to create application with Murano CLI or API or from another application in MuranoPL code. Though it should be relatively easy to implement such feature.

Hi Stan,

This article will help you to understand the working of heat nested templates:

Also the package that I am using is of heat templates for clearwater IMS deployment which is hosted at:

Thanks alot Stan!! Its working now.

Thanks Stan Lagun, that solved my question.
