I have too many machines floating around, some virtual, some physical, and they’re getting added and removed semi-frequently as I play around with different tools/try out ideas. One recurring pain point is I have no easy way to manage SSH keys around them, and it’s a pain to deal with adding/removing/cycling keys. I know I can use AuthorizedKeysCommand on sshd_config to make the system fetch a remote key for validation, I know I could theoretically publish my pub key to github or alike, but I’m wondering if there’s something more flexible/powerful where I can manage multiple users (essentially roles) such that each machine can be assigned a role and automatically allow access accordingly?
I’ve seen Keyper before, but the container haven’t been updated for years, and the support discord owner actively kicks everyone from the server, even after asking questions.
Is there any other solution out there that would streamline this process a bit?
I’ve been using https://github.com/warp-tech/warpgate for essentially this purpose. It does kind of put all of your eggs in one basket so don’t expose this to the Internet and probably keep at least one other machine that has all the keys. I haven’t had any catastrophic issues so far other than my host going down (unrelated to this tool).
