@oleh Could you please take a look if it's possible with Apipie?
@dominik, although readme [1] says that it's possible to generate OpenAPI 2.0, but not tested in a while and also the library has few limitations. The original maintainer (and the person who added this functionality) was changed, so we would need to invest quite a time to fully support OpenAPI generation via Apipie.

Upon review of our valid but aging backlog the Satellite Team has concluded that this Bugzilla does not meet the criteria for a resolution in the near term, and are planning to close in a month. This message may be a repeat of a previous update and the bug is again being considered to be closed. If you have any concerns about this, please contact your Red Hat Account team. Thank you.
Thank you for your interest in Red Hat Satellite. We have evaluated this request, and while we recognize that it is a valid request, we do not expect this to be implemented in the product in the foreseeable future. This is due to other priorities for the product, and not a reflection on the request itself. We are therefore closing this out as WONTFIX. If you have any concerns about this feel free to contact your Red Hat Account Team. Thank you.
