A Beginner's Guide to eBPF Programming with Go

Explore the world of eBPF programming with Go in this comprehensive conference talk from GOTOpia February 2021. Dive into the fundamentals of eBPF, described as "Superpowers for Linux," and discover its applications in observability and security. Through live-coding demonstrations, learn how eBPF programs are loaded and executed in the kernel, and how user-space code communicates with them. Follow along as the speaker guides you through creating an eBPF "Hello World" program, working with eBPF maps, and recreating a bpftrace command. Gain insights into attaching custom code to events, exploring bpf syscalls, and understanding the relationship between eBPF programs and maps. This 36-minute presentation offers a beginner-friendly introduction to eBPF programming, complete with practical examples and explanations to help you harness the power of this exciting technology.
