title: Traefik Docker hot reload configuration
body: <p>I'm trying to update my traefik.yml from outside, and hope that the Traefik container instance which is setup via docker-compose.yml. But it turns out it didn't work.</p>
  <p>I've mapped traefik.yml into the instance:</p>
  <pre><code>volumes:
        - ./traefik/traefik.toml:/traefik.toml
  </code></pre>
  <p>but it does not seems to auto reload on file update.</p>
  <p>I've tried to shell into the container and check if the file is updated, and it seems to be updated fine.</p>
  <p>How can I make autoreload work in Docker?</p>
