Error running Docker-Compose up to bring up traefik

Question

After mounting the Docker-Compose.yml as follows:

version: '3'

services:
    proxy:
        image: traefik
        command: --web --docker --docker.domain=docker.localhost --logLevel=DEBUG
        networks:
            - webgateway
        ports:
            - 80:80
            - 8080:8080
        volumes:
            - /var/run/docker.sock:/var/run/docker.sock
            - /dev/null:/traefik.toml
networks:
    webgateway:
        driver: bridge

I try to start the container with the command:

docker-compose up

But I get the following error message:

Creating network "traefik_webgateway" with driver "bridge"
Creating traefik_proxy_1 ... done
Attaching to traefik_proxy_1
proxy_1  | 2019/09/23 00:18:38 command traefik error: invalid node traefik: no child
traefik_proxy_1 exited with code 1

I tried to create a file called traefik.toml to mirror to the container with the following content:

# traefik.toml
logLevel = "DEBUG"
defaultEntryPoints = ["http", "https"]
[entryPoints]
  [entryPoints.http]
  address = ":80"

But I also made the mistake:

Creating network "traefik_webgateway" with driver "bridge"
Creating traefik_proxy_1 ... done
Attaching to traefik_proxy_1
proxy_1  | 2019/09/23 00:23:55 command traefik error: read /traefik.toml: is a directory
traefik_proxy_1 exited with code 1

I have tried several times to start traefik but all without success. Follow this tutorial from Digital Ocean and I also got the error:

2019/09/23 00:16:46 command traefik error: field not found, node: entrypoint

NOTE: I tried in 4 different machines, every time getting similar errors:

• On Windows with Docker desktop
• On Ubuntu from WSL (On windows)
• On Ubuntu 18 clean on a machine created on Amazon AMI
• On a machine preconfigured by BITNAMI with MEAN stack

[Resolved] What I did:

version: "3.3"

services:
  traefik:
    image: "traefik:v2.0.0-rc3"

    command:
      - "--api.insecure=true"
      - "--providers.docker=true"
      - "--providers.docker.exposedbydefault=false"
      - "--entrypoints.web.address=:80"
      - "--defaultentrypoints=http,ws"
    ports:
      - "80:80"
