How do i add external service using labels/command?

Traefik Traefik v2

Hi I'm running Traefik 2.9.6 using docker-compose.

How do I add a remote/external (not hosted on the same docker host) service using labels/commands?

I tried to add the following labels to the traefik container but that didn't work

- "traefik.enable=true"
- "traefik.http.routers.test.rule=Host(`test.localhost`)"
- "traefik.http.routers.test.service=test"
- "traefik.http.services.test.loadbalancer.server.ip=192.168.10.15"
- "traefik.http.services.test.loadbalancer.server.port=5568"

When I start Traefik and look in the dashboard it dosen't seem to find the test service.

Would you mind sharing your full Traefik static and dynamic config, and docker-compose.yml if used?

You should probably use .url. Do you have provider.docker enabled to read the labels?

I don't have any other config excluding my command section.

  traefik:
    image: "traefik:${TRAEFIK_VERSION}"
    container_name: "traefik"
    restart: unless-stopped
    read_only: true
    mem_limit: 2G
    cpus: 0.75
    security_opt:
      - no-new-privileges:true
    command:
      - "--log.level=DEBUG"
      - "--api.insecure=true"
      - "--providers.docker=true"
      - "--providers.docker.exposedbydefault=false"
      - "--entrypoints.web.address=:80"
      # Logs
      - --accesslog.filepath=/logs/access.log
      - --accesslog.format=json
      - --accesslog.fields.defaultMode=keep
      - --accesslog.fields.headers.defaultMode=keep
      - --log.filepath=/logs/traefik.log
      #- --log.format=json
    labels:
      - "traefik.enable=true"
      - "traefik.http.routers.test.rule=Host(`test.localhost`)"
      - "traefik.http.routers.test.service=test"
      - "traefik.http.services.test.loadbalancer.server.ip=192.168.10.15"
      - "traefik.http.services.test.loadbalancer.server.port=5568"
    environment:
      - TZ=Europe/Stockholm
    ports:
      - "80:80"
      - "443:443"
      - "8080:8080"
    volumes:
      - ./traefik/logs:/logs

Did you see my comment regarding .url? You should try

.loadbalancer.server.url=http://192.168.10.15

Update: Seems you can't use .loadbalancer.server.url in labels, so you need to create a dynamic config file with loadbalancer and load that file via provider.file in your static config.

Thanks that explains why it didn't even show up in the ui or the logs!
