Running one whoami service is ok, running two does not work

[marcvander]

Hey, I have been trying to run two whoami services to test Traefik's routing capabilities.

I have found a compose template here: traefik-best-practice/docker-traefik-dashboard-letsencrypt/docker-compose.yml at main · bluepuma77/traefik-best-practice · GitHub

When I run one whoami service, it works fine, I see it on the Traefik dashboard under HTTP Routers, and I can access it by going to my-url/whoami. Here is the compose file:

version: '3.9'

services:
  traefik:
    image: traefik:v3.0
    ports:
      - 80:80
      - 443:443
    networks:
      - proxy
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
      - letsencrypt:/letsencrypt
      #- /var/log:/var/log
    command:
      - --api.dashboard=true
      - --log.level=INFO
      #- --log.filepath=/var/log/traefik.log
      - --accesslog=true
      #- --accesslog.filepath=/var/log/traefik-access.log
      - --providers.docker.network=proxy
      - --providers.docker.exposedByDefault=false
      - --entrypoints.web.address=:80
      - --entrypoints.web.http.redirections.entrypoint.to=websecure
      - --entryPoints.web.http.redirections.entrypoint.scheme=https
      - --entrypoints.websecure.address=:443
      # remove next line when using Traefik v2
      - --entrypoints.websecure.asDefault=true 
      - --entrypoints.websecure.http.tls.certresolver=myresolver
      - --certificatesresolvers.myresolver.acme.email=myemail@test.com
      - --certificatesresolvers.myresolver.acme.tlschallenge=true
      - --certificatesresolvers.myresolver.acme.storage=/letsencrypt/acme.json
    labels:
      - traefik.enable=true
      - traefik.http.routers.mydashboard.rule=Host(`my-url`)
      - traefik.http.routers.mydashboard.service=api@internal
      - traefik.http.routers.mydashboard.middlewares=myauth
      - traefik.http.middlewares.myauth.basicauth.users=test:$$apr1$$H6uskkkW$$IgXLP6ewTrSuBkTrqE8wj/

  whoami:
    image: traefik/whoami:v1.8
    networks:
      - proxy
    labels:
      - traefik.enable=true
      - traefik.http.routers.mywhoami.rule=Host(`my-url`) && (Path(`/whoami`) || PathRegexp(`^/whoami/`))

      - traefik.http.middlewares.mywwwredirect.redirectregex.regex=^https://www\.(.*)
      - traefik.http.middlewares.mywwwredirect.redirectregex.replacement=https://$${1}
      - traefik.http.routers.mywhoami.middlewares=mywwwredirect

networks:
  proxy:
    name: proxy

volumes:
  letsencrypt:
    name: letsencrypt

Now when I try to add a second whoami service, they don't appear under HTTP Routers anymore, and I get a 404 Page not found when accessing my-url/whoami or my-url/whoami2. Here is the compose file:

version: '3.9'

services:
  traefik:

    ports:

      - proxy
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
      - letsencrypt:/letsencrypt
      #- /var/log:/var/log
    command:
      - --api.dashboard=true
      - --log.level=INFO
      #- --log.filepath=/var/log/traefik.log
      - --accesslog=true
      #- --accesslog.filepath=/var/log/traefik-access.log

      - traefik.http.middlewares.myauth.basicauth.users=test:$$apr1$$H6uskkkW$$IgXLP6ewTrSuBkTrqE8wj/

  whoami:

    networks:
      - proxy
    labels:
      - traefik.enable=true
      - traefik.http.routers.mywhoami.rule=Host(`my-url`) && (Path(`/whoami`) || PathRegexp(`^/whoami/`))

      - traefik.http.middlewares.mywwwredirect.redirectregex.regex=^https://www\.(.*)
      - traefik.http.middlewares.mywwwredirect.redirectregex.replacement=https://$${1}
      - traefik.http.routers.mywhoami.middlewares=mywwwredirect

  whoami2:
    image: traefik/whoami:v1.8
    networks:
      - proxy
    labels:
      - traefik.enable=true
      - traefik.http.routers.mywhoami.rule=Host(`my-url`) && (Path(`/whoami2`) || PathRegexp(`^/whoami2/`))

      - traefik.http.middlewares.mywwwredirect.redirectregex.regex=^https://www\.(.*)
      - traefik.http.middlewares.mywwwredirect.redirectregex.replacement=https://$${1}
      - traefik.http.routers.mywhoami.middlewares=mywwwredirect

networks:
  proxy:
    name: proxy

volumes:
  letsencrypt:
    name: letsencrypt

Of course my-url is not the url I try with, I hid it for privacy.

Anyone has an idea what I am doing wrong when I'm trying to run two whoami services ?

Thanks a lot!

I found the solution myself!

For both services whoami and whoami2, I had the same variables:

traefik.http.routers.mywhoami.rule
traefik.http.middlewares.mywwwredirect.redirectregex.regex
traefik.http.middlewares.mywwwredirect.redirectregex.replacement
traefik.http.routers.mywhoami.middlewares=mywwwredirect

For the service whoami2, I changed to the following:

traefik.http.routers.mywhoami2.rule
traefik.http.middlewares.mywwwredirect2.redirectregex.regex
traefik.http.middlewares.mywwwredirect2.redirectregex.replacement
traefik.http.routers.mywhoami2.middlewares=mywwwredirect2

It worked! I can now access both services with their respective url

So basically the variables have to be unique.
