I’m not sure the username matters, but I set it to “git” as that is what the login for gitlab uses. I then pointed it to my *private* key on the machine and gave it a description. Now the key shows up in the system. Once I had setup the ssh private key, which allows Jenkins to connect to the git host over ssh (i.e. git clone git@server:user/repo.git), I needed to setup API Access for Jenkins to get metadata from GitLab.
