Serving Swagger UI and editor using Docker Compose and Traefik - docker-compose

Question

My first attempt to start and use Swagger UI and Swagger Editor in the same time.
My approach is to define two services using Docker Compose and hiding them behind a reverse proxy, in this case Traefik.
But, something is wrong with my compose file and I can't figure out.
version: '3'
services:
traefik:
image: traefik:v2.5
restart: always
command:
- --accesslog
- --api.insecure=true
- --providers.docker
- --providers.docker.exposedbydefault=false
volumes:
- /var/run/docker.sock:/var/run/docker.sock
ports:
- "80:80"
- "8080:8080"
swaggerui:
image: swaggerapi/swagger-ui
restart: always
environment:
- PORT=8081
expose:
- 8081
labels:
- traefik.enable=true
- traefik.http.routers.swaggerui.rule=Host(`swaggerui`) && Path(`/ui`)
swaggereditor:
image: swaggerapi/swagger-editor
restart: always
environment:
- PORT=8082
expose:
- 8082
labels:
- traefik.enable=true
- traefik.http.routers.swaggereditor.rule=Host(`swaggereditor`) && Path(`/editor`)
Any suggestion?

Answer 1

You have to specify named entrypoint address (actually port number in container) in Traefik configuration at first
command:
...
- "--entrypoints.swaggerui.address=:8081"
At the second step you should add label for swaggerui container, just like this
labels:
- "traefik.enable=true"
- "traefik.http.routers.swaggerui.entrypoints=swaggerui"
...
After the above steps, everything should work
