Docker is the hottest shit in virtualization, a quasi-standard for application containers isolated from each other. The larger the machine parks to be managed, the more worthwhile it is to set them up and “orchestrate” them.

But Docker can also be worthwhile on a smaller scale: complex applications that would normally require a server admin to install and configure numerous packages can be “deployed” – installed, started, stopped, restored to a previous state or deleted – with just a few commands.

The version control system Git is used for downloading and synchronizing the image files.

Installation

Installation via the Ubuntu package sources is possible:

sudo apt-get install docker.io

However, since Docker is developing rapidly, it is worthwhile to pull the latest version via the setup script from get.docker.com:

wget -qO- https://get.docker.com/ | sh
