I think that federated gitlab instances could be a good next step forward for becoming independent from big companies.
At the moment I host a lot of my code to Github because of discoverability, but I do not feel comfortable with depending on Microsoft for this service. Gitlab is a self hosted Git server, but there is no way to federate the instances like on Lemmy. Are there any projects that deal with this?
Ignoring the public/private repo issue for the moment. Let’s assume this is only for FOSS projects. How do solve the issues of Authorization and Recoverability?
In theory you could implement an allowlist instead of the current ban list that Lemmy and others use for Communities. But this raises a 2nd problem, recoverability…
If the instance that contains my account goes down how can I ensure that I can still contribute to my repositories? I could create accounts on multiple instances and authorize all of them, but this increases the attack surface of someone gaining access to one of my accounts. At least with a centralized backup like GitHub, should I forget my password I at least temporarily have my SSH/GPG keys. And if I lose my SSH/GPG keys I still have my GitHub account to upload new ones to. Maybe a variation on ActivityPub could be created that uses SSH/GPG keys instead of an account name?
So maybe not unsolvable but at least some very interesting problems to solve first.
