This course provides an in-depth exploration of Linux namespaces, which are used in a wide array of virtualization and sandboxing technologies such as Docker, LXC, Flatpak, Firejail, Systemd, and various web browsers. In addition, the course covers the Linux capabilities model, since an understanding of that model is essential to understanding the operation of user namespaces, which are a cornerstone of many of the aforementioned applications. Detailed presentations coupled with carefully designed practical exercises provide participants with the knowledge needed to understand, design, develop, and administer such applications.


Audience and prerequisites

The primary audience comprises designers and programmers building privileged applications, container applications, and sandboxing applications. Systems administrators who are managing such applications are also likely to find the course of benefit.

In order to get the most out of the course, participants should have:

Note: knowledge of some fundamental Linux/UNIX system programming concepts (fork(), execve(), waitpid(), basics of programming with signals, the /proc filesystem) would be helpful. The essential details of those topics will be briefly covered at the start of the course.

Course format

The course employs a lecture+lab format.

Lab sessions

A significant part of the course is spent on practical exercises. The lab sessions also provide participants with the opportunity to obtain one-to-one assistance from the trainer on the course material and exercises.

Course materials

Course participants will receive a course book of around 200 pages that includes all of the slides and exercises presented in the course.

The course book has been developed by the trainer, and is constantly updated based on ongoing changes in the Linux kernel, as well as practical teaching experience in courses. The course book is printed on demand for each course, in order to ensure that it is completely up to date with current Linux developments.

In addition to the course book, participants will receive a copy of The Linux Programming Interface, in ebook form.
