Right now I have only two Fedora-based Docker images -
https://registry.hub.docker.com/u/znmeb/osjourno-rd/ is the most
active and the test suite is

a. Make sure it builds on Docker Hub
b. docker run
c. Browse to the RStudio Server and make all the documents from
templates (by hand).

I can probably automate the third step via Firefox but I haven't taken
the time to do that.

I am planning to integrate it with a PostgreSQL/PostGIS image and a
Redis image in the near future but I may use the "official" images
from Docker Hub (on a Debian base) rather than the ones in
"fedora-dockerfiles"..

Given a working Docker image, is there some combination of 'docker
export', tar archive manipulation and 'docker import' that can achieve
the same effect? I tried just piping an export with packages removed
to an import, but that didn't make the image smaller.

BTW, this conversation is fractured between this mailing list thread
and the TRAC issue #66. We should merge the threads somehow.
