[Kwiver-users] KWIVER Docker Usage: KWIVER_PLUGIN_PATH

[David Stoup]

I think you're right Matt, we should update the Docker images. Also, FFmpeg
is one of the few arrows that doesn't enable automatically when the package
is found. I always need to explicitly turn that one on. I would argue that
for consistency, that should be fixed as well.

I don't know that anyone is responsible/tasked for updating Docker
containers per se, but Taylor has often done it for releases. We might
consider a nightly 'master' flavor that gets pushed from a successful
nightly dashboard run. I can look into making that happen as well if it
makes sense to you.
