Hi, Evidently you don't feel the need for Docker and don't believe it's useful of needed, which is of course totally fine. I won't try to convince you since I've tried before and failed :) (if other are interested I cover some of the differences between docker and lxc here: http://stackoverflow.com/questions/17989306/what-does-docker... ) However there are obviously people who disagree with you and find that Docker s…
There's a lot of people on HN, and many of them simply aren't familiar enough with technology not to buy into every product shilled in a blog post or news article. It's like the "HN effect" is convincing people that because it's on the front page, it's somehow intellectually stimulating, superior, or factually correct, when often this isn't the case. Luckily we have comments to put forth alternate views.
Does this force the other major PaaS providers like Heroku to support Docker? Seems like you'd need more providers on board for true portability. Awesome news though.
Redhat's in an interesting position here. They've got a lot of capital & a strong presence in the enterprise but OpenShift is still a minor player in the PaaS market. They have the resources & the credibility to push an open container & give it credibility while also being in a position to benefit financially from commodity containers - anyone that moves from Heroku to hosted OpenShift is a win for them as is any company that goes to RH for their own cloud.
Lol. Still a lot of people who think that Red Hat derivatives are the only "enterprise-grade" server distros. Ubuntu and Debian work great.
Many enterprises will only use RHEL (tooling, support, market maturity etc), hence 'enterprise-grade'.

If the two of you have a history, that's fine, but I think the OP made a fair comment, and you've attacked him personally rather than replying to the seemingly-valid point he made.
I think the answer is that Docker is in fact less portable than previous standards (e.g. bare disk VM images), but is potentially a lot more efficient (now that AuFS has been dumped). Is that correct?
I would very much like to use Docker/containers to provision and deploy my software stacks on a beefy server I have. The ideal for me would be a whole VM in a container (nginx/uwsgi/redis/postgres/etc), but Docker can't currently do that (it only runs a single process). Is there a practical/good way to easily do what I want, with Docker or another tool?
It uses Go, LXC, and HAProxy.

You should checkout ShipBuilder [1][2]. ShipBuilder is a freely available open-source self-hosted PaaS -- it aims to be an open clone of Heroku. It uses Go, LXC, and HAProxy. [1] https://github.com/sendhub/shipbuilder [2] http://shipbuilder.io Disclaimer: I am a committer on the project
Then I could run it on the free ProxMox, which has built in clustering for up to 16 hardware nodes.
Given how powerful today's servers are, and how much RAM they can hold, you could spend $200K on hardware(about $10K per server with 256GB RAM, plus Infiniband switches and cabling) and have an amazing PaaS setup to offer (or use for yourself).

I can't make anyone's mind up for them. But if all they ever read are the hyperbolic marketing pieces about the glories of one tool, they're less likely to take the time to vet the claims and compare it to other tools.

These are worthwhile improvements.
