Webfinger and multiple Fediverse services on a domain

Submitted ⁨⁨1⁩ ⁨year⁩ ago⁩ by ⁨thisisawayoflife@lemmy.world⁩ to ⁨selfhosted@lemmy.world⁩

How does this work? How do you host pixelfed.domain.com and mastodon.domain.com together in the same domain, with queries for “@user@domain.com” to the webfinger host path?

The webfinger includes the subdomain. So the webfinger would be either @user@mastodon.domain.com or @user@pixelfed.domain.com, given your example.

  Does it still work that way when using the web_domain setting?

I can’t speak for those two services in particular, but I know that Matrix will check domain.com/.well-known/matrix/server to see what (sub)domain is responsible for domain.com. I suspect other services also use .well-known too.

  Yes, they use a webfinger on the .well-known path.

I’ve thought that if some dev created a webfinger reverse proxy they would be the hero of the fediverse.

  I’ve thought about doing this. It seems simple enough, though it would need a front end to be user friendly. I could build the rest api pretty quickly.
