I am trying do configure my docker compose to use traefik as reverse proxy to my nodejs app.  
It is running locally at host `nodejsdeploy.betorobson` which I have add a entry at hosts file to point out my local machine. So far my nodejs works by its own on port 3000.

So, it is working when I load on browser URL [http://nodejsdeploy.betorobson:3000](http://nodejsdeploy.betorobson:3000)

My aim is to use traefik as reverse proxy on port 80.

Here is my docker compose which I am trying a few setups, you can see some comments lines which represent some of those frustrated setup that I have tried before.

Applying this compose setup, I can see the traefik dashboard running on port 8080, but when I try access the nodejs thought the port 80, it shows `404 page not found`

```auto
version: "3"

services:
  app:
    labels:
      # - "traefik.backend=app"
      - "traefik.port=3000"

Docker file

```auto

WORKDIR /usr/app

RUN yarn

COPY . .

EXPOSE 3000
CMD ["yarn", "start"]

Hello,

you are using the Traefik v1 labels with Traefik v2, it's not possible.

Always use an explicit version instead of `latest`: ex `traefik:v2.1`, `traefik:v1.7`
