Global HTTPS redirect works. but not example.com > www.example.com

I read here (Redirecting to an external domain with traefik | Jens Knipper) that "multiple levels of redirects do not work. If you also want to do a global https-redirect and www redirect for your domain you are not able to do both". Is this true, please dear god, say it isn't so.

Use 3 backticks before and after code/config to make it readable, in yaml every space matters.

The simple Traefik example has a www to non-www example, that works.

as I said it's not working, have you any experience in this, can you share anything the works for you?

thanks for tip on backticks, i did try that at first but did not see any preview and then searched for the blockquote button

you say the example works, i have tried, does it work with global https redirect, is it setup in my code as it should be:

thanks and best regards,

When using

you need to place labels under compose deploy section (doc).

thank you, your github page got me going :pray:

I noticed it is for traefik 3, but got it going on 2.

Is there a release date for 3?
