If one needs a docker container to run a text editor, I think that says all that needs to be said about it.

Well, sort of. Something like spacevim requires some dependencies I imaging. Docker is sort of a package manager, so it makes sense to run the 1.1G docker image to see what you're getting into.

Anyway, this way I saw an issue early on that stopped me from going any further, and saved me much time and heart ache.

Sticking to my plain old .vimrc for now.
