title: multiple binaries in a docker container based on scratch
body: <p>I have a spec for a container that requires two binaries to be executed one after the other. I would prefer to inherit from the scratch image so that the container is no larger than the sum of the two executables. The obvious way to accomplish this is to inherit from alpine or some other small OS but I'd prefer scratch. Also, the CMD, RUN and EXEC commands in the Dockerfile seems to require a shell and so scratch is not an option. Building two containers and then a docker swarm is interesting but not the answer.</p>
