SSH Agent plugin doesn't work well with docker pipelines

Issue Type:	Bug
Assignee:	Unassigned
Components:	ssh-agent-plugin
Created:	2017/Mar/22 10:05 PM
Priority:	Minor
Reporter:	Erik Lattimore

I've tried

 
                                                                dockerImage.inside {
  sshagent([...]) {
    sh '...'
  }
}
 
                                                            

and this appears to fail because the ssh-agent gets launched but then the next command
appears to be ssh-agent -k which kills the process before the sh step has a chance to run despite the sh command being inside the sshagent block.

And also

 
                                                                sshagent([...]){
  dockerImage.inside {
    sh '...'
  }
}
 
                                                            

fails (I think) for a more predictable reason: the ssh-agent stays running and the env variables get
set correctly inside the container, however the socket is in /tmp on the container server which is not visible to the container (by default).

Re: SSH Agent plugin doesn't work well with docker pipelines

Well, I think I found how to reproduce the issue.

The following code works as expected if running on non-docker agent and does not work inside docker:

 
                                                                agent {
    docker {
        label 'bsp'
        image 'my-registry/my-image'
        reuseNode true
    }
}
stage("Some stage") {
    steps {
        sshagent(['some-id']) {
            script {
               sh "# some code that uses ssh"
            }
        }
    }
} 
                                                            

However, if I put sshagent() inside script {...} block it works:

 
                                                                agent {
    docker {
        label 'bsp'
        image 'my-registry/my-image'
        reuseNode true
    }
}
stage("Some stage") {
    steps {
        script {
            sshagent(['some-id']) {
               sh "# some code that uses ssh"
            }
        }
    }
}
