Docker is pretty easy too, at least from linux -- spinning up a
manylinux environment is just "sudo apt install docker.io && sudo
docker run -ti quay.io/pypa/manylinux1_x86_64 bash". But I haven't
tried using docker on other platforms (though I know it's possible to
install docker somehow), and I haven't tried using vagrant at all :-).

Given my ignorance, I'd be interested to hear more about what makes
you excited about vagrant!

The more the merrier :-). And the conda linux and manylinux build
environments are *very* similar.

AFAIK the only real difference between them is that when you're
targeting conda you can assume that the conda version of libstdc++ is
already present, and conda's libstdc++ is newer than the version of
libstdc++ you're allowed to assume is present when distributing
manylinux wheels (which is just whatever is installed on the system).
This almost never matters though: the compilers that ship with the
manylinux image can handle any version of C++ up to C++11, and will
work fine for both conda and manylinux packages. Or, if you really
need support for C++14, then you can always use a newer compiler and
then use auditwheel to bundle your newer version of libstdc++ in with
your wheel.
