Docker isn't that hard to explain.
And, no, it isn't a VM or a VM controller. (That's Vagrant)
Docker is similar to Solaris Zones, BSD Jails, and Linux Containers. It's not (supposed to be) a virtual machine (with all the OS code, drivers, etc.) but rather lightweight container allowing calls down to the OS.
(And no, I have no idea how Docker is going to make that work with Microsoft)
So...why it is important?
Well the difference with Docker is that it allows you to push your application AND ENVIRONMENT at the same time...to Development, to Testing...and (ideally) to production. (You wouldn't normally push a Vagrant file to production, for example).
It (ideally) prevents problems of code failing in production because a config file was off, or an environment variable that wasn't set, or a wrong version of a library.
There is a LOT of hype and some concerns about security - but that's it in a nutshell.

 I haven't clue as to what those things are.

Hmm, I've heard those promises before and I've never seen a technology solution that actually works. It usually requires people following correct procedures rather than some complex technology.

Indeed, how that is going to work in Windows is going to be interesting to see.

That definitely helps -- Thanks!
I'd still like to see an actual example though - here's the problem, here's the workflow people go through - here's how Docker solves the problem and this is what people do differently when using Docker.
So far, the website reminds me of a typical Linux developer trying to explain a product - it instantly dives into geek technology rather than focusing on people and their processes. It's a problem I constantly struggle with myself too!

Not yet, I'm just now switching over to vagrant, but docker is next on my list of things to check out.
|

Yes. In my experience the major advantage of VE instances over a full VM is the incredibly fast start-up time and minimal system load.
If you're looking to distribute pre-configured machine instances you should also evaluate Vagrant [^]. Vagrant can provision both Docker containers and Virtualbox VMs.

Hi Chris,
My understanding is that it's just like Sandboxie[^]
Basically a sandbox for you application with it's own registry and hdd all in a virtual space.
Hope this helps.
Cheers

My wife is extremely allergic to cats.
Will she also be allergic to tigers?
Kind of urgent.
Not really urgent, but I do suddenly find myself pondering this
Some men are born mediocre, some men achieve mediocrity, and some men have mediocrity thrust upon them.
|
|
|
|
|
Put her in a cage with tigers, see if she survives 
[edit] give her epipen if you don't want to risk her life
|
|
|

|

Yeah, they don't know either.

I'm also allergic to (some) cats. I'm guessing that exposure to a Tiger will be more detrimental to her health.
But the answer to your REAL question is No, she won't be allergic to Tiger suits[^].

Yeah, I've got the same some problem.
Oddly enough, it seems to be only black fur. (And, no, not psychological. I don't even have to see the cat in question for my eyes to start puffing up and my throat closing.)

Any species that's black or just certain black ones?
In America your antibodies might be labeled as racist.

I *think* only generic American shorthairs, but I don't recall ever coming across any black longhairs, so...no way to tell for sure.

My Doctor said I'm allergic to cats and dogs. But I never suffered that - and I eat them since I was I little boy.

Not if you shave the tiger first. I've never heard of any complaints about a shaved kitty.
Will Rogers never met me.

I have yet to meet a woman who's allergic to a Jaguar.

You're totally welcome. Just glad I could help a bit.

Normally TWC suck massively - they are an expensive, poorly run excuse for a cable network company who have terrible customer service and a crappy DVR menuing system.
However, I had a letter stating that my internet service was being upgraded free of charge and a new cable modem would be on it's way to me. Yippee! Something for nothing!
Of course, that's not what actually happened. They sent the wrong modem and then deactivated me when I rang because they didn't understand what I was saying (that comes of having overseas call centers).
Anyway, the correct modem arrived yesterday. Plugged it in. Called to activate. Done. under 10 minutes and now with 50Mbps as measured by speedtest.net as opposed to the 15 I was getting before.
For once they got it right.
Now, if only they would have some decent channels to watch...

Virgin Media did something similar about one year ago - "We are upgrading you from 10mbps to 20mbps completely free!"
One month later a letter arrives through the door from Virgin Media - "We are raising your monthly bill by £3 due to inflation etc."...
