Ten years ago, I walked into the British Embassy in Budapest, paid my £80 and got my new passport issued the same day!
This time around I am in the UK. I will go up to Petit France and do the fast-track for £100.

After reading (for maybe the 10th time over the last year):
Docker is an open platform for developers and sysadmins to build, ship, and run distributed applications. etc...
I still don't know:
1. What it actually does
2. What's wrong with how I'm currently delivering web and desktop applications
3. And therefore, why I need it.
4. And does it really do what the hype says it does, even though I don't understand it?
Oh sorry. The answer to your question in "No."

I've not used it personally, but some on our team have used it. It's essentially an abstraction layer for deploying on Linux servers.
Yeah - their market-speke is hard to get through. Just tell us what it is, dammit!
It's going to be integrated into Windows Server 2015 (a neat trick, it would seem). To me it's like deploying an install as a VM, without the actually deploying a VM (and it's Gig's of OS)

We are going to hear a lot more about Docker in the years to come. It is difficult to explain it in few words, but it is basically a "container". It leverages recent OS technologies that allows one process to be isolated from others. It was first developed for Linux, now it is finding its way to Windows. This is essential for Microsoft, as Docker images are becoming the standard way for cloud deployments. Do you want to install Redmine? Sure, you need to install Ruby, MySQL and then the Redmine itself. It is far easier to find a dockerized redmine and deploy from there in seconds.

Then you don't know what it is. If you knew it well, you'd be able to explain it to us.

Docker is nicely explained in this "short" video. If you don't have the time to watch it, you should at least know that is quickly becoming the standard for cloud deployment.

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.
Some men are born mediocre, some men achieve mediocrity, and some men have mediocrity thrust upon them.

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?

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