This is more of an observation than a question... I'm looking at Docker (and Project Atomic) because 1] Docker's been getting a lot of (IT) press lately as the next great thing in cloudy server/SAAS deployments, and 2] I want to evaluate its utility for occasional provisioning of assorted servers, including http+php and node. And let's be clear about one thing: on pretty much any current Linux server that's already dead easy.
But AFAICT, doing it on Project Atomic (and maybe/probably other optimized-for-docker linux releases) is ludicrously difficult, tedious and time-consuming. I dodged CoreOS after a quick sniff, because I'm a long-time Fedora user, and hoped to leverage that experience: "It provides all the benefits of the upstream distribution". Not.
Is Docker a solution in search of a problem? What's the promised land look like anyway?
I get that PA/Docker are supposed to provide enhanced security and easier deployments on reduced resources. Where's the beef on that middle one?
