Is it possible to use a Docker container as a build node without using the Jenkins agent?

  • 772

I am trying to use an RHEL 5 Docker container to run Jenkins jobs, but RHEL 5 does not support anything more recent than Java 8. Is there a way to run a Jenkins job in this container without using the Jenkins agent to communicate to the Jenkins server? Maybe with SSH?

(Don't ask me why RHEL 5, it just is. I can't change it.)

    I figured it out using a declarative pipeline and the docker object. No agent or Java needed. This simple demonstration pipeline works with an RHEL 5.11 container and Jenkins 2.452.1.

    pipeline
{
  agent any
  stages
  {
    stage('One')
    {
        steps
        {
            script
            {
                docker.image('rhel5:latest').inside
                {
                    sh "cat /etc/redhat-release"
                    sh "echo 'Done!'"
                }
            }
        }
    }
  }
}
