> When building a docker image, the docker tool uploads the contents of the current directory - the "build context" - to the docker daemon.
> On a dev build, that can be huge; with intermediate artifacts and test logs, it can easily be a few gigabytes. And that copy happens for each one of the 3 images build by the docker tool script.
> It would be nice to make that faster to speed up iterative development.
