Docker "Hello, World"


Details
From the presenter (Rob Richardson, who has graciously agreed to present at our group):
"Welcome to Docker
--------------------------------
Docker is carefully tucked between virtualization, continuous deployment, and pure awesome. We'll look at the commands and ecosystem around building infrastructure as code, deploying a swarm, and sharing images on Docker Hub. We'll see how easy it is to create Linux and Windows docker images, and run both single containers and a whole system. Come see why devs and ops love Docker."
This is is a "DEFINITELY Bring Laptops" event as this will be a live discussion/demo and some of the tricks and what-not are best experienced as they are invoked at the keyboard.
I'm posting the details a bit early as this is a subject that needs MUCH research. You should be prepared with an already-functioning installation of Docker on your laptop (not a big deal, at least for a reasonably hefty system - I boot to a virtual machine that runs Docker within the VM just fine - they fixed the bugs about six months ago that were causing problems when running inside a VM (the actual case was a Linux VM running inside a Windows VM, running a container - how's THAT for technology!) and now it seems to Just Work).
Why is this important to the up and coming developer? Simple - containers ARE the future! Even the "Evil Empire" Microsoft has admitted this - how do they know? Over half of the subscription systems running on Azure are Linux systems. There is a system in Windows now called WSL (pronounced "Weasel") that stands for the Windows Subsystem for Linux - so even MS has embraced the Linux world. The OS is becoming less and less important and being relegated back to the realm in which it should have stayed - just a source of standard resources for use by other systems. It should make no difference if the host is Windows or Linux or whatever and containers give us this choice. This should be a Fun session!
