traefik: how can I route a static file from / to one of the containers, in docker-compose.yml?

Question

I have a specific service inside docker-compose.yml called 'fastapi', which is based on the fastAPI python package.

      fastapi:
        image: fastapi
        labels:
          - "traefik.frontend.rule=PathPrefixStrip:/fastapi"
          - traefik.port=5000
        volumes:
          - ./fastapi:/app
          - ./data:/data

traefik route to the the fastapi through localhost/fastapi .

However: There is an internal call to openapi.json where the server search for in /openapi.json, and get a "404 page not found" error. How can I route static files from localhost/openapi.json to localhost/fastapi/openapi.json .

I tried this rule, but it does not work!

labels:
   - "traefik.frontend.rule=PathPrefixStrip:/fastapi,Path:/openapi.json"

好吧，我错过了FastAPI文档中的明显答案： https ://fastapi.tiangolo.com/tutorial/sub-applications-proxy/

FastAPI(openapi_prefix="/subapi")
