peterwwillis makes 3 claims: 1) docker does not allow standardized, portable deployment of applications 2) docker is a "fancy wrapper" over lxc and adds no substantial value, 3) anyone who disagrees with this is spreading "lies" and "hyperbolic marketing claims" which will cause the readers of hacker news to form an incorrect and uninformed opinion.
I addressed points 1 and 2 by linking to this thread: http://stackoverflow.com/questions/17989306/what-does-docker.... It lists half a dozen ways that I believe docker is different from lxc. The first item in the list is "portable deployment across machines".
I then called him out on point 3 because I consider it unfair and harmful. First it insults the intelligence of the hacker news readers ("they eat the marketing up, but I don't!"). Second it introduces FUD as an substitute for facts. Shouting "marketing hype!" in hacker news is the equivalent of shouting "anti-american!" in Congress. How many people will come away from this thread thinking "huh I wonder if docker is marketing hype after all?" simply because peterwwillis claimed it? Talk about a marketing hyperbole.
I take it you two do have history, because I didn't really pick up on #2 and #3 from his comment. I would suggest that every time you say "docker is not just a fancy wrapper around LXC", mentally people assume that docker is probably little more than a fancy wrapper around LXC. Methinks you doth protest too much!
For #1, you've linked to a thread in which you claimed docker is more portable than LXC. I think you guys are arguing at cross-purposes here: you're saying that you're more portable because e.g. you abstract away the IP configuration (true), he is saying you're not portable because you're tied to specific kernel features (also true?).
I, for one, would like to hear more of Docker's benefits clearly explained (i.e. less shipping container metaphors, and more talk of IP configuration). I'd also like to hear more about the limitations of Docker (e.g. what kernel versions can I move containers between, on which kernel versions is it secure etc).
As for #2 and #3, those seem like non-fact-based arguments, so I'll let you and peter continue screaming at each other about who is more wrong on the Internet :-)

I'm sorry you took offense; it was intended as friendly feedback. I'm familiar with Docker. If you have actual answers, it would be much more constructive to post relevant links.
