Deep dives into DevOps and Server Side topics where theory blends with hands-on examples. You can try out commands from each tutorial in the attached remote playground, either from the browser or via SSH access from your local terminal — no extra setup required.
Tutorials crafted by iximiuz Labs to help you master DevOps and Server Side topics.
Begin with the basics to understand Docker and Kubernetes networking: learn how to create and interconnect Linux network namespaces using only command-line tools.
Tutorials from outstanding independent authors proudly hosted by iximiuz Labs.
This lab shows how to use eBPF to transparently redirect inbound traffic through an Envoy proxy on the server side, without modifying the application or client. You’ll learn how eBPF can intercept and restore connections so the service remains unaware of the proxy in the network path.
This lab teaches you how to use eBPF to transparently intercept and redirect a client's outgoing traffic to an Envoy proxy without requiring any changes to the application code. You will build a system that recovers original connection metadata via socket-level hooks and uses SO_MARK to prevent infinite routing loops, replacing traditional, complex iptables rules with a high-performance eBPF alternative.
In this tutorial, you will learn how to build an Layer 2 DSR load balancer using eBPF/XDP, where backends send responses directly back to clients bypassing the load balancer.
Learn how to implement a basic per-client ICMPv6 packet rate limiter using eBPF/XDP. This tutorial shows how to track client activity with eBPF maps and enforce limits directly in the kernel—without any user-space interaction.
