Presented by:

Dario Faggioli

from SUSE Labs

Dario is a Virtualization Software Engineer at SUSE. He's been active in the Open Source virtualization space for a few years. Initially, he worked only on Xen-Project, and he is still the maintainer of the Xen hypervisor scheduler.

Back during his Ph.D., he worked on real-time scheduling on Linux, and he's one of the original authors of what today is the SCHED_DEADLINE scheduling class. These days, he works on Linux kernel, KVM, Libvirt, and QEMU. He mainly focuses on scheduling and on measuring and improving performance.

Since 2010, he has spoken at several events and conferences such as Linux Kernel Summit, Linux Plumbers, Xen-Project Developers Summit, FOSDEM, LinuxLab, OSPM and previous editions of Open Source Summit & KVM Forum. He has also given technical seminars about Computer Architecture at the University of Pisa, the University of Modena, and the Scuola Superiore Sant'Anna.

It's no news or secret that containers are good at providing multiple and different testing environments, or at offering a way of deploying apps and services that are completely decoupled from the host OS. E.g., spin up a distro X container, check if code compiles there (and dispose of it).

How about the opposite? I.e., having one (or more!) stateful and persistent environment(s), tightly coupled with the host and sharing as much information and configuration as possible with it. Why? Well for running that one app, which is only available for another distro, with just a click on a desktop launcher icon. Or for doing all kind of experiments, inside our development environment, without risking the stability and the consistency of the system. Well, yes, containers can do these things too. And in openSUSE, we have both toolbox and distrobox, that can make these examples, just reality!

In this talk, we'll explain what they are and how to use them for spawning development and application environments, based either on the same distro you have on the host or on different ones, and inside of which you still have all your file. A working space that, despite being containerized, you can access seamlessly from within GNOME Builder or open new terminals directly inside of it and create launcher icons for apps installed in there.

We'll offer (more) examples and show how this can be very useful, both on immutable (like MicroOS) and on "traditional" (like Tumbleweed) systems.
