Swap out the base image to get new system dependencies included #20

Open richfitz opened 6 years ago

This is a real pain with docker's diamond problem. If the instance needs more system dependencies then both the shiny images (shiny and builder) need rebuilding:

perhaps a list of apt packages will be enough in many cases
interpolate the new image name into the dockerfile
support for organising building and pushing these images from the instance
rebuilding the builder image is trickier unless the package source is copied over into the shiny image

The simplest way of doing this would to move provisioning the builder container out to a further volume, then we don't have a nasty build chain
