That is exactly what I'm looking for.
The goal seems to be similar to Tom's.

eg. libjpeg, libpng for GIL, zlib for others, etc.
Makes sense.

I've been using Vagrant for long time, but docker seems suitable for
that purpose too,
especially after I experienced it via multi-docker build workflow on
CircleCI 2.0
(already used for Geometry and GIL).

Ideally, if the community could agree to maintain single boostorg/docker

I'd like to be able to pull docker image(s), run regression tests and
submit to the Boost waterfall.
I'd also like to get some *BSD images - especially after long standing
failures of GIL on those systems.
Ideally, if I could run a script overnight that pulls images one by one
runs the tests and submits the results. I'm sure such automation is feasible.

I've been using Vagrant to provide various Windows-based development
environments, and I feel the same pain.

If there is boosorg/docker, then there will be documentation on
I'll try to help.
