Redirect from non-www to www with traefik 2

Traefik Traefik v2
,
2 
  labels: 
    traefik.enable: 'true'
    traefik.http.routers.training.rule: Host(www.########.ml,########.ml)
    traefik.http.middlewares.test-redirectregex.redirectregex.regex: ^http://########.ml/(.*)
    traefik.http.middlewares.test-redirectregex.redirectregex.replacement: ########.ml/$${1}

This is another solution I've tried but it doesn't work.
