I'm trying to get Jenkins up and running with a GitHub hosted repository (using the Jenkins Git plugin). The repository has multiple git submodules, so I'm not sure I want to try and manage multiple deploy keys.
My personal GitHub user account is a collaborator of each of the projects I wish to pull in with Jenkins, so I've generated an SSH key within /var/lib/jenkins/.ssh and added it to my personal GitHub account.
However, when I try and add the repository URL to my Jenkins project configuration, I get:
Failed to connect to repository : Command "git ls-remote -h [email protected]:***/***.git HEAD" returned status code 128:
stdout:
stderr: Host key verification failed.
fatal: The remote end hung up unexpectedly
Likewise, when I schedule a build I get:
stderr: Host key verification failed.
fatal: The remote end hung up unexpectedly
I've also tried setting up an SSH config file as outlined here, but to no avail.
Can anyone shed any light? Thanks
EDIT
I should add that I'm running CentOS 5.8
This question is related to
git
ssh
jenkins
continuous-integration
It looks like the github.com host which jenkins tries to connect to is not listed under the Jenkins user's $HOME/.ssh/known_hosts. Jenkins runs on most distros as the user jenkins and hence has its own .ssh directory to store the list of public keys and known_hosts.
The easiest solution I can think of to fix this problem is:
# Login as the jenkins user and specify shell explicity,
# since the default shell is /bin/false for most
# jenkins installations.
sudo su jenkins -s /bin/bash
cd SOME_TMP_DIR
# git clone YOUR_GITHUB_URL
# Allow adding the SSH host key to your known_hosts
# Exit from su
exit
According to this article, you may try following command:
ssh-add -l
If your key isn't in the list, then
ssh-add /var/lib/jenkins/.ssh/id_rsa_project
Have you tried logging in as the jenkins user?
Try this:
sudo -i -u jenkins #For RedHat you might have to do 'su' instead.
git clone [email protected]:your/repo.git
Often times you see failure if the host has not been added or authorized (hence I always manually login as hudson/jenkins for the first connection to github/bitbucket) but that link you included supposedly fixes that.
If the above doesn't work try recopying the key. Make sure its the pub key (ie id_rsa.pub). Maybe you missed some characters?
This works for me if you have config and the private key file in the /Jenkins/.ssh/ you need to chown (change owner) for these 2 files then restart jenkins in order for the jenkins instance to read these 2 files.
