Hello everybody,

I’m currently trying to auto-generate Ansible modules from OpenAPI (Swagger) definitions. During research I stumbled upon the [`ansible.content_builder` collection](https://github.com/ansible-community/ansible.content_builder). This collection is suspect to be replaced with the [`ansible-creator` utility](https://github.com/ansible-community/ansible.content_builder/issues/84) - anyhow, this tool still [lacks OpenAPI support](https://github.com/ansible/ansible-creator/issues/106).

I tried to get `ansible.content_builder` running, but [stumbled upon various issues](https://github.com/ansible-community/ansible.content_builder/issues/71).

Next, I discovered [`ansible-waldur-generator`](https://github.com/waldur/ansible-waldur-generator) that generates code, but isn’t working for me - the documentation is very hard to get into.

**My question** : Are these the only two utilities to auto-generate Ansible modules from OpenAPI definitions these days? Am I missing something?

Thanks a lot in advance!

Hi. While I may have no real answer, the thing you are doing reminded me of what Citrix did for their NetScaler product line.

Take a look at:

and

> <https://github.com/netscaler/ansible-collection-netscaleradc/blob/main/plugins/module_utils/module_executor.py>

This is not OpenAPI per se but the idea is the same. They have a huge strict API specification in form of a Python dict (almost JSON) and a “module executor” that can generate modules on the fly using the specification. The modules are then trivial. They just call the module executor.

That’s a good catch, thanks for sharing!
