I did a search through the Discourse and have gandered at the docs, but am not finding an answer to something: in what way, if any, can an instance of Mastodon be used with multiple domains?
I notice that the configuration docs mention
ALTERNATE_DOMAINS but it isn’t clear what those env variables do, individually or in combination. If I missed that, please give me a pointer to what page(s) clarify those.
For example, presume I have multiple related domains, say, domain1.tld and domain2.tld, or more.
I’m wondering, if one can have an instance of Mastodon with two domains, such that people with @firstname.lastname@example.org could also have at the same time, and pointing to the same profile, @email@example.com (if that makes sense, and I’ve got the notation correct).
I’m assuming no, but those configuration variables make me wonder. So, I thought I’d ask, as it weighs into my thinking. If yes, what about three or four (If I were to, for example, grab domain1.social and domain2.social for the instance as well)?
I’m sure I can point multiple domains, as aliases or whatever in DNS, to a main canonical one used for an instance, but I wondered about the way the profiles work, and if they’d be interchangeable instead of one being canonical and the others merely pointers to, or that resolve to, the main one.
