title: traefik permissions 777 for acme.json are too open, please use 600
body: <p>Yes, 
  I get this when I try to run traefik with https. Problem is I mount the dir on my Win7 machine but I cant chmod the file.</p>
  
  <p>The mount is working but file permissions are off.</p>
  
  <p>looks like this:</p>
  
  <pre><code>volumes
    - d:/docker/traefikcompose/acme/acme.json:/etc/traefik/acme/acme.json:rw
  </code></pre>
  
  <blockquote>

    starting provider *acme.Provider: unable to get ACME account :
    permissions 777 for /etc/traefik/acme/acme.json are too open, please
    use 600"</p>

  <p>If I remove the acme.json file I get this:</p>
