How would one make a subdomain and/or path go to some public url?

Traefik Traefik v2

Basically, i would like to have a subdomain or path go to some public url such as a reddit page or google document, but i have no idea how i would do that.

pretend i want to go to the traefik subreddit, i would like the following to [separately] take me there
t-reddit.mydomain.com
mydomain.com/t-reddit
these should take me to https://www.reddit.com/r/Traefik/

how would i do this? it should also be easy to add more different paths or subdomains, as i will copy-paste the example for other links.

edit: to be clear, i would like to do this in a dynamic file

This is a job for the redirectRegex middleware.
I would make the regex very broad (^.*$) and use it on the routes you want to redirect.

I have a ./rules/ directory for traefik, could you give me a couple of examples of a .toml or .y(a)ml that would do what I want?

http:
  routers:
    one:
      rule: (Host(`t-reddit.mydomain.com`) || (host(`mydomain.com`) && Path(`/t-reddit`)))
      entrypoints: web
      middlewares: 
        - redirect-reddit
      service: dummy
  middlewares:
    redirect-reddit:
      redirectRegex:
        regex: ^.*$
        replacement: https://www.reddit.com/r/Traefik/
# If you want a pemanent redirect
        # permanent: true
  services:
    dummy:
      loadBalancer:
       servers:
         - url: http://127.0.0.1:9999

Hey, thanks. I haven't used yaml files with traefik yet, but I think I understand how it works. (Looks much nicer than toml tho) and it works nicely!
Question: what is that dummy service for?

Your routers need a service. This is one way of providing that in a self contained fashion.

You could enable ping --ping on traefik and then use the ping@internal as the service instead.
