I thought Docker wanted to be "just Docker" and not leverage all the tools and stacks which can or cannot be used with Docker? There is absolutely nothing wrong with the fist, but I am pretty sure Docker was pushing itself as "just Docker". All their latest acquisitions don't really reflect the image they want to portray.
I don't get the advantage of that image, though. It makes sense for them to acquire things that make it easier to get started with Docker. I wouldn't be surprised if they acquired Panamax too.
