This plugin directly supports ARGs, so we should not need to filter the Dockerfile
Also supports dependencies from one image to another, so would be good to convert the https://github.com/GoogleCloudPlatform/openjdk-runtime project as well.

alternately.... this project could convert to using https://dmp.fabric8.io/ the same as openjdk-runtime

What about https://github.com/GoogleContainerTools/jib it is a solution from Google not sure if it has all the needed features though.

IMO, jib is very nice and should do all we need.
