I have failed to remove www. How can I achieve it?

This is traefik v2.3.5 docker-compose.yml file.

Hello @fatihyildizhan,

I tried to find your issue but it was a bit hard without your static configuration, so I have made some assumptions. In the Traefik configuration, I found the following errors:

  • I might be wrong but I the entrypoints attached to wwwsecure-catchall router must be https.
  • Because of the router priorities, if you want this router to catch all www requests, then you will have to assign it a high priority (something like traefik.http.routers.wwwsecure-catchall.priority=10000).

In the container configuration:

  • In your bodrum-web-secure router, I think the Host(www.domain.com) rule is not needed
  • When you attach the bodrum-compress middlewares to the bodrum-web router you are overriding the redirect middleware you have already defined. To attach both middlewares, you should do: traefik.http.routers.bodrum-web.middlewares=bodrum-web-https-redirect,bodrum-compress

As a side note, I think it's possible to simplify your configuration (removing the http router in your container config) by using entrypoint redirection.

Hope this helps!
