Tell git which private key to use for a user without home folder

Question

I was reading the question Tell git which private key to use, and the answer doesn't apply for a case were the user doesn't have any home directory.

We're setting up a Jenkins server right now, and the user who run Jenkins doesn't have any home folder. But that particular user must access a GIT repository.

How can the user running GIT use a key authentication?

// , What if the machine doesn't even have the key in question? Can one specify which forwarded identity to use? — Nathan Basanese, Sep 11 '15 at 19:37

The environment variable GIT_SSH tells git what ssh exectutable to use. So you could create a script something like:

#!/bin/bash
/usr/bin/ssh -i /path/to/identity.file "$@"

Then chmod it executable, and set GIT_SSH=/path/to/sshscript

advancing to the next roadblock: my ssh client then tries to update known_hosts and that fails! – GLRoman Aug 29 '18 at 21:41

@GLRoman The UserKnownHostsFile option let's you specify where the file should be – Paul Aug 29 '18 at 22:09
