Hi, I fielded this question a while ago on my blog:
http://lso.umsystem.edu/~pottingerhj/article/38/why-vagrant-instead-of-docker
In the mean time, I've since seen a Vagrant-based tool for Wordpress
development, that uses Docker under the hood. It's pretty cool, and worth
checking out:
http://www.sitepoint.com/wocker-easy-dockerized-wordpress/
What makes this environment really cool is that, you get the convenience of
easily setting up a dev environment, and when it's done, you get a really nice
tool for quickly spinning up new instances of Wordpress, inside that
environment. And these same tools can become deployment tools.
OK, but, setting down the toys :-) I think Tim Donohue's distinction is a good
one: Vagrant is a dev environment tool, and has many very nice features built
up to support that use case. Docker is a deployment tool (and a pretty young
one, still). Containerization is a big deal in the ops world. It's very likely
that the "powers that be" at your institution have some opinions on the
subject, and you'll need to enlist their support before you get too much
farther with experimenting with a deployment tool like Docker.

Hi
my boss discovered a dspace docker
so which one should I do - docker or vagrant ?
They sound awfully alike
the host can connect to things : tomcat / ssh / ...
files can be shared between host and vagrant/docker guest
it appears to be easy to hand a ‘vagrant’ or a ‘docker’ to another developer
so what’s the deal ?
why one over the other ?
