Check slave.jar versions of slaves against expected version on Jenkins master
import jenkins.model.*
import hudson.remoting.Launcher
import hudson.slaves.SlaveComputer
def expectedVersion = Launcher.VERSION
for (computer in Jenkins.instance.getComputers()) {
if (! (computer instanceof SlaveComputer)) continue
if (!computer.getChannel()) continue

// https://registry.hub.docker.com/_/maven/
def maven32 = docker.image('maven:3.2-jdk-7-onbuild');
stage 'Mirror'
// First make sure the slave has this image.
// (If you could set your registry below to mirror Docker Hub,
// this would be unnecessary as maven32.inside would pull the image.)
maven32.pull()
// We are pushing to a private secure docker registry in this demo.
