systemd (for some time now) provides a powerful chroot alternative to linux users for creating quick and lightweight system containers using power ofcgroups and socket activation.

There is a lot more to “systemd” than this, but that’s for some other post. Until then can explore it, starting here.

There is a utility “systemd-nspawn” provided by systemd which acts as container manager. This is what can be used to easily spawn a new linux container and manage it. It has been updated with (the systemd’s amazing trademark feature) Socket Activation.

This enables any container to make parent/host’s systemd instance to listen at different service ports for itself. Only when those service ports receive a connection, these container will spawn and act to it. Voila, resource utilization and scalability concepts.
More of this can read in detail at: http://0pointer.de/blog/projects/socket-activated-containers.html

Here we’ll see some way to quickly start using it via some custom made commands.
