I’m interested in setting up my own instances for Lemmy, Mastodon, and Matrix.
Can I use the same https://domain.tld for all of them without any subdomains?
For example:
[email protected]
[email protected]
[email protected]
Will this work across all of my self-hosted instances, or do I need to append a subdomain for each, e.g., [email protected]?
All those services use a protocol named WebFinger that allows for having the servers in different domains but showing the users as being in a main domain. For example, my self-hosted Synapse server is at matrix.domain.tld, but my users are all like [email protected].
Unfortunately I don’t really know how to set it all up manually, I just let Yumohost take care of managing it.
Should partly be possible to do. Matrix: https://github.com/spantaleev/matrix-docker-ansible-deploy/blob/master/docs/configuring-well-known.md
Lemmy is not working. But might be at some point: https://github.com/LemmyNet/lemmy/issues/2608 But that issue also mentions on how it works with mastodon.
Matrix (or even easier XMPP) can coexist on the same domain with Lemmy or Mastodon, but with two ActivityPub services that is AFAIK not possible.
Regardless of configuration, you still need to access the instance from mastodon.mydomain.tld or lemmy.mydomain.tld, but you can configure the Mastodon to use @[email protected] as its identifier by setting
WEB_DOMAIN
tomydomain.tld
.Mastodon documentation on the topic: https://docs.joinmastodon.org/admin/config/#web_domain
You are able to host all these services and more on the same domain. I do a similar thing with different services at different subdomains. I don’t believe the
username@
portion can help point to different services, that syntax is usually associated with email addresses.I think the best way to go about it would be having different subdomains such as
lemmy.domain.tld
,matrix.domain.tld
, etc.
To accomplish that, I have a wildcard subdomain point to my server, my reverse proxy (Caddy) handles figuring out which subdomain maps to which service on top of handling TLS certificates for me.Good to know and I was hoping that’s the case. As soon as my new domain resolves I’m going to install lemmy, matrix, and funkwhale.
Are you running all of yours in containers?
Please do add a tag to your post as stated on the sublemmy sidebar! Thank you. :)
Done. Thank you for the reminder, and for modding this new home for selfhosted conversations.
You’re very welcome. :)
