How reach Swagger docs under Traefik proxy?

Hi! I have docker-compose file with the following services:

services:

  reverse-proxy:
    image: traefik:v2.4
    container_name: reverse-proxy
    command: 
      - "--api.insecure=true"
      - "--providers.docker"
    ports:
      - "80:80"
      - "8080:8080"
    labels:
      - traefik.enable=true
      - traefik.docker.network=pred-network
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
    networks:
      - pred-network

  api-service:
    image: x86_64/prediction-service:0.8.1
    container_name: api-service
    environment:
      SERVING_SERVICE: model-service
    expose:
      - 8000
    labels:
      - traefik.enable=true
      - traefik.http.routers.api-service.rule=Host(`api.service.localhost`)
    networks:
      - pred-network

Container api-service has python script with one path for POST requests: http://api.service.localhost/predict/. This path works perfectly for POST requests. It looks like Swagger docs should be under http://api.service.localhost/docs/. But when I go to this page I am getting:

Not Found
HTTP Error 404. The requested resource is not found.

Environment:

python==3.8
uvicorn==0.13.4
fastapi==0.63.0
python-multipart==0.0.5
numpy~=1.19.5
Pillow==7.0.0
min-tfs-client==1.0.2

I would appreciate any ideas!

Removing the trailing slash does not help 😦

@gyKa Thanks. I added app = FastAPI(root_path="/api/v1") to script but I still cannot connect.

Also tried to change docker-compose so webapp could have only two pathes:

http://traefik.service.localhost/ -> Traefik UI
http://api.service.localhost/ -> 'Hello-Word' page from api-service

But it does not work either

Here is my updated docker-compose file:

version: '3.8'

services:
  reverse-proxy:
    image: traefik:v2.4
    container_name: reverse-proxy
    command: 
      - "--api.dashboard"
      - "--providers.docker"
    ports:
      - "80:80"
      - "8080:8080"
    labels:
      - traefik.http.routers.traefik.rule=Host(`traefik.service.localhost`)
      - traefik.http.routers.traefik.service=api@internal
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
    networks:
      - pred-network
  api-service:
    image: x86_64/prediction-service:0.8.1
    container_name: api-service
    environment:
      SERVING_SERVICE: model-service
    expose:
      - 80
    labels:
      - traefik.http.routers.service.rule=Host(`api.service.localhost`)
      - traefik.http.services.service.loadbalancer.server.port=80
