An Applied Introduction to eBPF with Go
#1about 2 minutes
What is eBPF and why should you use it
eBPF allows you to run custom sandboxed code inside the Linux kernel without modifying kernel source code or loading modules.
#2about 3 minutes
Understanding user space versus kernel space architecture
An operating system is divided into user space for applications and kernel space for core functions, with system calls acting as the interface.
#3about 2 minutes
Why eBPF is better than traditional kernel programming
eBPF provides a safer and more dynamic way to run code in the kernel compared to recompiling the kernel or writing unstable kernel modules.
#4about 2 minutes
How the eBPF architecture and workflow operates
An eBPF program written in C is compiled to bytecode, loaded into the kernel, and executed by a virtual machine when a specific event occurs.
#5about 3 minutes
Writing an eBPF program in C to trace processes
This code walkthrough demonstrates how to write a C program that uses a ring buffer map to capture process ID and name on creation.
#6about 3 minutes
Loading the eBPF program with a Go user space application
Learn how to use the Cilium eBPF library in Go to generate bindings, load the eBPF object, and attach it to a kernel probe (Kprobe).
#7about 3 minutes
A deeper look at eBPF hooks and maps
Understand the role of different hook types like Kprobes and map types like ring buffers for attaching to events and sharing data.
#8about 5 minutes
Tracing network packets at the driver level with XDP
This example shows how to use an XDP hook and an LRU hash map to efficiently count incoming IP packets directly from the network interface.
#9about 2 minutes
Exploring real-world eBPF projects and use cases
Discover how open-source projects like Cilium and companies like Edge Delta use eBPF for Kubernetes networking, security, and observability.
