Copy Container Images Like a Pro
by Ivan Velichko
Practice copying container images from one repository to another using the docker, crane, skopeo, and regctl tools.
eBPF Beginner Skill Path
Learn eBPF from the ground up — from writing and running your first program, to storing data in eBPF maps, inspecting and monitoring kernel activity using bpftool and bpftop, and understanding how the verifier ensures safe eBPF execution. Finish with a hands-on challenge to put your new skills to the test.

Beyond Docker: Run Containers Across Runtimes
by Ivan Velichko
Explore how different container runtimes - Docker, Podman, nerdctl, ctr, and runc - execute containers. Compare their UX, architecture, and impact on containerized applications.
eBPF CO-RE Skill Path
In this learning path, you’ll go from comparing different tracing program types — tracepoints, raw tracepoints, kprobes, and fprobes — to writing portable eBPF programs that work reliably across environments. You’ll also understand the role of BTF and learn how to make your eBPF code portable even when BTF isn’t available on the target system.
Get Started with Linux Control Groups (cgroup v2)
by Ivan Velichko
Start by learning how to limit process resources in Linux using cgroups—from the most basic, hands-on cgroupfs manipulation to the more convenient systemd-run command. Then, explore how Docker and Kubernetes leverage cgroups to control the resource usage of containers and pods.

We know firsthand that there's no one-size-fits-all approach to learning. That's why each part of iximiuz Labs is designed to support you at every stage of your journey.
The best way to build proficiency is through practice in a realistic yet safe environment - that's exactly what Playgrounds provide. With just a one click, you can get a Linux VM, Docker, or even a multi-node Kubernetes cluster ready in seconds, letting you experiment freely without risking your host system.
When you're looking to deepen your understanding with theory, our Tutorials and Courses offer clear explanations to help you grasp even the most nuanced topics.
For a more structured approach, Skill Paths and Roadmaps offer carefully curated, step-by-step guidance, so you always know exactly where you're headed next.
Finally, when you want to put your skills to the test, our interactive Challenges simulate real-world scenarios, helping you apply your knowledge through practical, hands-on exercises.
