Re: [tosca] TOSCA for Ansible

Thanks! Nothing significant yet, just various Ansible hello-world-like scenarios.

There are various challenges ahead:

Generating "hosts" for Ansible. I think this might require a special Ansible profile with a "Host" capability. Otherwise it's hard to see how Ansible would know. Or maybe metadata that can be applied to any capability type or node type?
Attributes. I think these will have to be set by an explicit Ansible role.
Graph-iteration (this is a more general problem in Ansible, which has overly simple loops).

Ciao Tal!

This looks awesome! Are there specific scenarios in which you tested this?

Wouldn't it be nice if your Ansible playbooks could consume TOSCA?

Well, now they can. This is still a work-in-progress, but Puccini now includes an Ansible module for TOSCA (which in turn relies on the Python wrapper).

Here's an example of a simple playbook:

https://github.com/tliron/puccini/blob/main/examples/ansible/hello-world.yaml

There's still much more on the TODO list for supporting various Ansible use cases, but even at this early stage there's a lot that's possible by simply iterating on resolved node templates and doing the usual Ansible stuff.

Feedback most welcome!
