I'm an employee of Docker, Inc. although my thoughts are my own, etc...

I must say that this is great. I've been advocating this sort of usage of Docker for a while as most still think of Docker or containers as individual units. I'm happy to see others adopting the viewpoint of using container groups.

However, it is something I do hope to eventually see supported within Docker itself.

Also, recently, I've been telling others how since October you could do this exact same thing using OpenStack Heat. Using Heat and Docker is similar to Fig, the configuration syntax is quite similar even, but it requires the heavy Heat service and an OpenStack cloud. That means that for most people, it isn't even an option. It's great that Fig now provides a solid lightweight alternative.

As 'thu' has said already, people want and need these features quickly and I expect in the next year we'll see serious interest growing around using these solutions and solving these problems.
