I am not that familiar with docker, but I thought the idea was that you
build your own container images with your requirements? ie re-build the
image just once on only one server and then send it around to all the
others.

Alternatively, if you did not want to re-build the images themselves,
you could always setup a gentoo binhost on one machine and make all the
other containers pull those packages so there will not be the wasted
time compiling.
