systemd-nspawn is a simple container manager for Linux systems that is shipped as built-in component of systemd. systemd-nspawn is as easy to use as chroots, but suitable for booting up full-blown Linux systems. It's great as light-weight container tool that just works. systemd-nspawn makes working with containers easy. In this presentation I will introduce you to systemd-nspawn, and show how you can set up a bootable Linux container in a one command, and then boot it up in a second one -- and all that with built-in tools of your favourite (systemd-based) distribution. You might learn a thing or two about Linux containers in general, and the technology they build on. We'll discuss how we are working on integrating container support as closely into the core OS as possible, trying to provide similar integration as Zones on Solaris.
