Description

Brendan Gregg from Netflix described eBPF as “Superpowers for Linux,” and over the last couple of years we’ve seen an explosion of tools that use it to power observability and more. If you’re not content simply to run those tools but want to understand what eBPF is and how you could write your own eBPF programs, you’re in the right place.

Liz Rice dives into eBPF and why it’s so powerful, which is that it enables running bespoke programs directly in the kernel. You’ll look at the BCC framework, which makes it easier to write, compile, and run your eBPF code. With live-coding examples, you’ll not only see how to get started with eBPF but you’ll also explore what’s happening to give you an understanding of how it works and how user-space code can communicate with eBPF programs inside the kernel.

Prerequisite knowledge

  • A working knowledge of Linux
  • Familiarity with user space, kernel, and that syscalls are functions that allow user space to make requests of the kernel
  • General knowledge of C and Python

What you'll learn

  • Gain the knowledge and confidence to start writing eBPF programs of your own
