Building Your Own Kubectl Trace on Steroids Using BPF Libraries in Go, Rust, Python and C

Explore the world of BPF libraries and build advanced tracing applications for Kubernetes in this comprehensive conference talk. Dive deep into the ecosystem of BPF libraries across multiple programming languages, including Go, Rust, Python, and C. Learn how to create a powerful tracing engine that goes beyond basic "printf" calls and simple data processing. Discover the differences between various libraries and their capabilities for system tracing using BPF tracepoints and other program types useful for tracing and profiling. Gain insights into when to choose tracepoints over kprobes and vice versa. Examine code samples in different languages, available on GitHub, and get hands-on experience with a custom "kubectl-tracex" tool that provides an alternative to the standard "kubectl-trace". By the end of this talk, you'll be equipped with the knowledge to build sophisticated tracing applications for your Kubernetes clusters using the most suitable BPF libraries for your needs.
