What's wrong with this docker-compose.yml file to start traefix, wordpress and mariadb containers?

Question

I am trying to configure and start docker containers for traefik, wordpress using mariadb The error below is that traefik can't find the traefik.toml file. I supplied the yml file for you to review and offer suggested changes.

I've been composing this yml file from varios sources on the web. The wordpress container and maria db containers startup fine. Traefik is the problem. Though I'm not totally sure about 8081:80 for the wordpress. To run wordpress by itself without traefik it is 80:80

version: '3'

services:
  reverse-proxy:
