Docker might sound like a complex technology, but in actuality it's a trend. As we all know, trends come and go, so rest assured that one day Docker will go away too. It just may not happen in your lifetime, but that does not mean it's not a trend.

Well, keep wondering. The fact is, no one really knows what Docker is or what it's good for. How do I know? I don't. And if I don't know, then no one knows.
