Traefik v2 listen on port - docker

Question

I am using Traefik v2 with Docker Swarm. I want to achieve the following routing:
mydomain.com:9000 -> Traefik dashboard
mydomain.com:5000 -> my application
docker-compose-traefik.yml
version: "3.7"
services:
traefik:
image: "traefik:v2.0"
networks:
- traefik-net
command:
- "--log.level=DEBUG"
- "--api.insecure=true"
- "--providers.docker.swarmMode=true"
- "--providers.docker.exposedbydefault=false"
- "--entrypoints.web.address=:5000"
ports:
- "80:80"
- "9000:8080"
volumes:
- "/var/run/docker.sock:/var/run/docker.sock:ro"
networks:
traefik-net:
external:
name: traefik-net
docker-compose-whoami.yml
version: "3.7"
services:
whoami:
image: "jwilder/whoami"
networks:
- traefik-net
deploy:
replicas: 3
labels:
- "traefik.enable=true"
- "traefik.http.routers.whoami.rule=Host(`mydomain.com`)"
- "traefik.http.routers.whoami.entrypoints=web"
- "traefik.http.services.whoami.loadbalancer.server.port=8000"
networks:
traefik-net:
external:
name: traefik-net
jwilder/whoami exposes port 8000 in its Dockerfile. I want to redirect port 5000 (my entrypoint defined in docker-compose-traefik.yml) to port 8000 in container.
I created network traefik-net with: docker network create -d bridge traefik-net.
I deployed both stacks with:
docker-stack deploy -c docker-compose-traefik.yml Traefik
docker-stack deploy -c docker-compose-whoami.yml Whoami
When I visit mydomain.com:9000 it opens Traefik dashboard as it should. When I visit mydomain.com:5000 it says that "This site can’t be reached".
My question is: How to redirect request to port 5000 (mydomain.com:5000) to port 8000 inside whoami container?

Answer 1

For anyone else having similar problems, I found a solution. I needed to change ports section in docker-compose-traefik.yml from
ports:
- "80:80"
- "9000:8080"
to
ports:
- "80:80"
- "9000:8080"
- "5000:5000" <-- add this
Hope this helps someone. :)
