Workshop: Linux Containers In (Less Than) 100 Lines of Shell - Michael Kerrisk, man7.org Training and Consulting

Friday October 9, 2026 14:00 - 15:30 CEST

Chamber Hall (Floor 3)

Using just shell commands, can we create a "decent" container–something like the degree of isolation provided by a Docker or Podman container? If we work at it, we can come reasonably close. Furthermore, we can do so using less than 100 lines of shell commands. Along the way we can learn quite a bit about the nature of a container and the Linux kernel mechanisms used to implement containers. In this session, we'll see how to use a few standard shell commands, plus the ever useful Busybox tool, to create a simple container. That container will have a root filesystem, employ Linux namespaces to provide isolation, and have an associated control group (cgroup) that allows us to limit the resources that the processes in the container can consume. Our container will have a superuser, and we’ll consider what it means to be superuser inside a container while at the same time being unprivileged outside the container.
