Maybe I'm missing something here but I don't see this as being particularly useful?
It's a nice quick way to get an application running in Docker but realistically would you want to be depending upon these images in production?
The power I see in Docker is the ability to create portable images that contain everything my application needs. I don't want to depend upon Docker (the company) to figure out what these images should look like.
I understand where you're coming from. At first glance I thought it would be the return of the dreaded virtual appliance giving people no clue on how developer X got to end result Y.
However, this is not that. Docker simply gives more emphasis to officially maintained docker images of popular projects, all of which have Dockerfiles available for your inspection!
If the Dockerfiles were available, I would feel better about it. Just glancing around I couldn't find the stacks Dockerfiles, so not sure those are available.

Am I looking at this the wrong way?
