Where are Traefik logs?

Do you happen to know where the Traefik logs are located? I read the documentation on Traefik and it says it will output to stdout but when I start the docker container with docker-compose up -d it doesn't show anything in stdout after I try the domain name and pull up multiple linked docker containers.

I also tried to specify these:

    [traefikLog]
      filePath = "./traefik.log" #<--Tried this but It doesn't work, file empty and permissions set to 777
    
    [accessLog]
      filePath = "./access.log" #<--Tried this but doesn't work, file empty and permissions set to 777

I'm confused, am I missing something? or is Traefik supposed to be this quiet?

When I run it this is all I see, nothing afterwards.

    # docker-compose up
    Creating traefik ... done
    Attaching to traefik

Attached is my config. Thanks.

To see logs in the stdout event if you run docker-compose up -d:

docker-compose logs -f

https://docs.docker.com/compose/reference/logs/

FYI The path ./traefik.log is inside the Traefik container.

[traefikLog]
  filePath = "./traefik.log" 

With your files (without the section [traefikLog]), I see the logs.

However, your configuration have some issues:

    hostname: traefik

    container_name: traefik
    networks:
      - nginx-proxy
    ports:
      - "80:80"
      - "443:443"
    volumes:
      - "/var/run/docker.sock:/var/run/docker.sock"
      - "./traefik/traefik.toml:/traefik.toml"
      - "./traefik/acme.json:/acme.json"
    labels:
      - "traefik.enable=true"
      - "traefik.port=8080"
