Cannot start the provider *file

Traefik Traefik v2
1

I am trying to isolate static and dynamic configuration to be in separate files. Here are the files that I use:

docker-compose-traefik.yml

version: "3.7"

services:
  traefik:
    image: "traefik:v2.0"
    networks:
      - traefik-net
    ports:
      - "80:80"
      - "9000:8080"
      - "5000:5000"
    volumes:
      - "/var/run/docker.sock:/var/run/docker.sock:ro"
      - "./traefik.yml:/etc/traefik/traefik.yml"
      - "./dynamic_conf.yml:/etc/traefik/dynamic_conf.yml"

networks:
  traefik-net:
    external:
      name: traefik-net

traefik.yml

log:
  level: DEBUG

api:
  insecure: true
  dashboard: true

providers:
  file:
    filename: dynamic_conf.yml
    watch: true
  docker:
    swarmMode: true
    exposedByDefault: false

entrypoints:
  web:
    address: ":5000"

dynamic_conf.yml

http:
  routers:
    whoami:
      rule: "Host(`example.com`)"
      entrypoints: web
      service: whoami
  services:
    whoami:
      loadbalancer:
        server:
          port: 80
          sticky:
            cookie:
              name: StickyCookie

When I run the command...

docker stack deploy -c docker-compose-traefik.yml Traefik

...I get the following error in the logs:

level=error msg="Cannot start the provider *file.Provider: error reading configuration file: dynamic_conf.yml - open dynamic_conf.yml: no such file or directory"

All mentioned files are in the same directory on host.

What am I doing wrong?

Thanks for your interest in the project!

In fact, the filename in your traefik.toml is not relative to traefik.toml itself, but to the pwd when we run the traefik binary, so in the docker image case it's in /. You should use the path /etc/traefik/dynamic_conf.yml instead and it should work.
