[openstack-dev] Incubation Request: Murano

Hi Thomas, Zane,

Thank you for bringing TOSCA to the discussion. I think this is important
topic as it will help to find better alignment or even future merge of
Murano DSL and Heat templates. Murano DSL uses YAML representation too, so
we can easily merge use constructions from Heat and probably any other YAML
based TOSCA formats.

I will be glad to join TOSCA TC. Is there any formal process for that?

I also would like to use this opportunity and start conversation with Heat
team about Heat roadmap and feature set. As Thomas mentioned in his
previous e-mail TOSCA topology story is quite covered by HOT. At the same
time there are entities like Plans which are covered by Murano. We had
discussion about bringing workflows to Heat engine before HK summit and it
looks like that Heat team has no plans to bring workflows into Heat. That
is actually why we mentioned Orchestration program as a potential place for
Murano DSL as Heat+Murano together will cover everything which is defined

I think TOSCA initiative can be a great place to collaborate. I think it
will be possible then to use Simplified TOSCA format for Application
descriptions as TOSCA is intended to provide such descriptions.

Is there a team who are driving TOSCA implementation in OpenStack
community? I feel that such team is necessary.
