Jenkins Pipeline push Docker image

Question

My Jenkins job is Pipeline that running in Dockers:

node('docker') {
  //Git checkout           
  git url: 'ssh://blah.blah:29411/test.git'

  //Build
  sh 'make'

  //Verify/Run
  sh './runme'
}

I'm working with kernel and my sources take a lot of time to get it from GIT (it's about 2GB). I'm looking on how I can push the docker image to use it for the next build so it will already contain most of the sources. I probably need to do:

docker push blahdockergit.blah/myjenkinsslaveimage

but it should run outside of the container.

Answer 1

Found in pipeline syntax that following class can be used for building external jobs
