You can build a docker image in a vagrant VM on OSX and deploy that exact docker image to production.

If your vagrant image resembles production, it's probably fine, but there's a level of confidence to be reached from deploying the exact entire self-contained binary, shipping it through QA and staging, and eventually promoting it to production.

This should be made into an answer to the OP's question, because this is the use case that I think most people will wind up moving to docker for, if they do.

This is also a use case for not developing on OS X, which doesn't have anything to do with production anyway.

Can you clarify? Do you mean that one should only develop upon the platform that will be used in production?

Yes, the previous commenter is a purist with no battery life on their laptop.

Further, if you're in the middle of upgrading your production OS, does this mean that you need two developer machines?

C'mon!
