I know enough about docker to know that this is a good idea, but not enough
to review this diff, or your updated pull request.

Does anyone on the Mercury core team know docker well enough to do a review?

If not, maybe the best course of action is to simply approve a pull request, and
try out the result. Sadly, that won't be me, since my laptop's Linux is much too old
for docker.
