> I didn't see anything in the Rocket proposal that implied they thought the things Docker wants to add aren't needed I was referring mainly to this statement: "We should stop talking about Docker containers, and start talking about the Docker Platform. It is not becoming the simple composable building block we had envisioned." I agree with you that that doesn't necessarily mean that the Rocket team disputes the need…
> The announcement itself doesn't go into much detail as to which technologies those would be, though. That's part of the point. They want to be free to compose components depending on their customers needs. CoreOS already includes Fleet (orchestration of individual units), and their are putting effort into Flannel (overlay network), and Kubernetes (orchestration of "pods" of containers). But their market is enterpri…
I'd say that's completely valid. I was not trying to imply that the combination of CoreOS and tools such as Fleet, Flannel, Kubernetes etc. claimed to be a "simple, lightweight platform". Indeed, as you point out, the core component, i.e. Rocket itself, may well be more complex than "Docker classic."
I think your comments demonstrate accurately that the overall "Rocket ecosystem" will also address the inevitable enterprise requirements. Since most of the other tools you mention did not appear in the launch announcement, I think it's fair to say that describing Rocket as a response to the emerging 'non-simple Docker Platform' is, at the very least, inviting a comparison that isn't exactly apples to apples.
The overall point I was trying to make goes beyond Rocket, Docker, containers or any specific current technology or tool, however. The way the Rocket announcement was worded simply prompted on ongoing train of thought. Indeed, it's the many conversations in the past months around Docker that I've been involved in that have exemplified the belief/hope/wish that there finally is a new tool that will make boring enterprise problems magically "go away."
Docker, Rocket, and whatever tomorrow's favorite container framework turns out to be, are unlikely to be the last examples of that pipe dream, I think.
