Here is the announcement. As you can see they are using stupid words like trust in the cloud etc. The fact of the matter is that you are giving up control every time you put something in "the cloud" and simply have to trust the "cloud operator" and clouds are infiltrated and polluted these days.

From the look and feel of it - Docker resembles Git. And it has a certain appeal so do as I did and take this online tutorial without peeking.
It is an online terminal where you have to complete some commands and you do get hints all the way. I could go on now and tell you about my experience - but lets turn it around - take the test and you tell me.
You will have to use apt-get in the test environment but it will be in your repos so you can find out in your distros Wiki how to adapt this to your system.
This is bleeding edge technology so it is not meant for production use yet - which will make you extremely cool and some of the first in the world to master this new technology.
And once that is the case - we need to find out what this can be used for...

Where virtual machines each run a guest OS, Docker containerization shares the underlying host OS across all apps running in its sandboxes. It has a lower overhead than typical virtualization.
For instance, Docker could be used to run a database in one container and an app server in another, and the configurable isolation properties let an admin precisely dictate how information is passed between the two.
And yes! Docker runs on Windows too - kind of...Inside a VB
