Hi everyone - hope it's ok to announce a new open-source project; If you're adopting an OpenAPI/Swagger design-first approach with Traefik this one might be for you...
We've recently released Kusk - a tool for automatically generating Traefik configurations from an OpenAPI definition, including settings for things like CORS, timeouts and rate-limiting.
Kusk makes your OpenAPI definition the source-of-truth for your API deployment (if you're into that kind of thing) and it works nicely with both manual and automated CI/CD workflows (ArgoCD, etc).
Have a look and let us know if this makes any sense 
- thank you!
