Jenkins - Unable to git clone from slave node. SSH keys

Question

I have just set up my first Jenkins slave. I run the build, and I hit problems with the SSH keys. The master Jenkins server is running under the user 'jenkins'. I have set up the SSH keys such that I can SSH from the master to the slave without a password. e.g. From the master: ``` jenkins@master:~$ ssh slave Last login: Tue Apr 17 10:30:22 2012 from masterjenkins.com $ whoami jenkins ``` So that proves that the slave node is also running under the 'jenkins' user. (I have copied the public ssh key from the jenkins@slave to the remote git server). And I am able to issue the git clone manually from the slave, but when I kick off the build from the master I get these kinds of messages: ``` ERROR: Error cloning remote repo 'origin' : Could not clone git@host:abc hudson.plugins.git.GitException: Could not clone git@host:abc Caused by: hudson.plugins.git.GitException: Error performing command: git clone --progress -o origin git@host:abc /var/lib/jenkins/workspace/abc_build Command "git clon…

Accepted Answer

Based on the clone URL it appears you are mixing up two different authentication methods. You are trying to SSH into host as the user `git` not `jenkins`. Typically when you host your own GIT repositories and clone with git@servername:reponame you use something like gitolite.

Did you set anything up like gitolite?

Try ssh'ing like this instead as the jenkins user.

```
ssh git@slave 
```

Then see what that returns. This is an SSH more in line with the `git@host:abc` you are doing.

If you didnt setup anything else on your server machine, then change your clone url to `jenkins@host:pathtorepo`

Update

`/home/git/.ssh/authorized_keys`

Should have an entry like this: (This is all on ONE line)

```
# gitolite start
command="/home/git/bin/gl-auth-command jenkins",no
-port-forwarding,no-X11-forwarding,no-agent-forwarding,no-pty ssh-rsa AAAAB3NzaC1yc2EAAAABJQAAAIEAt3+od84Gc9NBVrVb3MKjekHcBDwXXONnVYMNVpuRadoz/FPJTkOIxozKVPJDPI670O252giYpF59sOKqAJL0xEVUrhq8cDFuFwQsSAp0ed1kp/GRxx+pwytL58rcVJEHAy2DkD1z5HlNaZyvIxQyfLTnYfuL1Hx6Qe7dal7mXO0= keycomment
# gitolite end
```

Add repository permissions to jenkins in gitolite: (You may have to clone on the same machine that is hosting your repositories, as the gitolite user)

```
git clone git@host:gitolite-admin 
cd gitolite-admin
cd conf
vi gitolite.conf
```

Now find the entry for 'abc' or add one if it doesn't exist

```
repo    abc
  RW+            = jenkins
```

Now commit and push changes

```
git commit -a -m "Adding user jenkins to repo abc"
git push
```

Now do your `ssh git@host` again to see if gitolite tells you about your new permissions.
