Collect Redoc FastAPI from some instances on an one page

Question

Is there any convenient way to put Redoc together from some insurances running on several ports, for instance:

• http://127.0.0.1:8000/redoc
• http://127.0.0.1:8001/redoc
• http://127.0.0.1:8002/redoc
• http://127.0.0.1:8003/redoc

Each instance presents itself Fast API with certain endpoints.

I'd want to have the starting page where the all endpoints would be presented, let's say http://127.0.0.1:8004/redoc

It could be done in your build pipeline, using the redocly join command (docs: https://redocly.com/docs/cli/commands/join/ and disclaimer: I work for Redocly). Grab each of the OpenAPI specifications, and put them into one combined file, would that do what you are looking for?
