We will present a Virtuozzo approach for fast creation of containers (lightweight virtual environments) with preinstalled Linux distribution and custom set of applications. The approach uses modified package managers of target distributions to create cache images with file systems (which are used as a basis for new containers) and to manage installed software in already deployed containers. In this talk we will discuss advantages and limitations of this technique with respect to other solutions such as Docker or LXC templates.

The talk is targeted at engineers working at containerized solutions as well as container users such as hosting providers.
