su as the
jenkins user to create some SSH keypair:
$ ssh-keygen -p
-p option; this will allow to avoid asking for a passphrase (which Jenkins cannot so running as a daemon).
Try to ssh on github:
$ ssh -T firstname.lastname@example.org The authenticity of host 'github.com (22.214.171.124)' can't be established. RSA key fingerprint is 16:27:ac:a5:76:28:2d:36:63:1b:56:4d:eb:df:a6:48. Are you sure you want to continue connecting (yes/no)? yes Hi username/reponame! You've successfully authenticated, but GitHub does not provide shell access.
Notice that you're asked to allow github's hostname to be added to your
known_hosts file: without completing this step, you're doomed.
Now, in the Jenkins project configuration interface, set the private repository url using the
git protocol, eg.
That's it, Jenkins will be able to clone and use your private repo.
If you know a better way, I'm all ears.
