I think I've found a possible solution in this post: http://colonelpanic.net/2011/06/jenkins-on-mac-os-x-git-w-ssh-public-key/
Jenkins on Mac OS X I just finished setting up a build server on Mac
OS X using Jenkins (formerly Hudson). The company I’m working for
(GradeCam) uses git and gitolite for our source control and so I
expected no trouble using Jenkins to build our tools using the git
plugin.
However, I quickly ran into a snag: the source control server is on a
public address and so our source code is not available except via ssh,
and gitolite ssh access uses private key authentication. Well, I’m an
experience unix sysadmin, so that didn’t sound like a big issue —
after all, setting up public key authentication is childs play, right?
Default install
The default installation of Jenkins on Mac OS X (at the time of this
writing) installs a Launch Agent plist to
/Library/LaunchAgents/org.jenkins-ci.plist. This plist file causes
Jenkins to load as user “daemon”, which sounds fine — except that the
home directory for the “daemon” user is /var/root, same as for user
root. This means that the .ssh dir in there will never have the right
permissions for a private key to be used.
Creating a new hidden user
My solution was to create a new “hidden” user for Jenkins to run
under. Following instructions I found on a blog post, I created a user
“jenkins” with a home directory “/Users/Shared/Jenkins/Home”:
sudo dscl . create /Users/jenkins
sudo dscl . create /Users/jenkins PrimaryGroupID 1
sudo dscl . create /Users/jenkins UniqueID 300
sudo dscl . create /Users/jenkins UserShell /bin/bash
sudo dscl . passwd /Users/jenkins $PASSWORD
sudo dscl . create /Users/jenkins home /Users/Shared/Jenkins/Home/
I then stopped Jenkins: “sudo launchctl unload -w
/Library/LaunchAgents/org.jenkins-ci.plist” and edited the plist file
to set the username to jenkins instead of daemon.
“chown -R jenkins: /Users/Shared/Jenkins/Home”
sets the permissions how they need to be, and then “sudo launchctl
load -w /Library/LaunchAgents/org.jenkins-ci.plist” should get you up
and running!
To get git over ssh running, “sudo su – jenkins” to get a console as
the jenkins user and set up the ssh keys and such. Make sure you can
ssh to where you want to go (or even do a test git clone) because you
need to save the keys so it doesn’t ask for them when jenkins tries to
do the clone.
That should do you! Hope it helps someone.
