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.
Learn how Linux containers are built from the ground up. Starting with the mount namespace and a root filesystem, see why PID, cgroup, UTS, and network namespaces naturally follow - and how this foundation makes concepts like bind mounts, volumes, and persistence in Docker or Kubernetes much easier to grasp.
How Virtual Machines were used to deploy services. What old problems containers solve and what new problems create. How Kubernetes used containers to recreate Virtual Machines in a better way?
Learn how to limit process resources using Linux cgroups - from the most basic and labour-intensive cgroupfs manipulation to the handiest systemd-run command.

In this lab, you’ll build a NAT-based eBPF/XDP load balancer from scratch and implement both round-robin and weighted round-robin backend selection. Along the way, you’ll learn how to manage state in eBPF maps and distribute traffic across backends based on simple and capacity-aware scheduling strategies.
Learn how to configure and use Kubernetes Runtime Classes to specify different container runtimes for your workloads. Explore different OCI runtimes and their scheduling constraints.
OpenScience Demo content: How to capture a massive piece of high-performance compute (HPC) code named Kaiju and Gamera in a Container
In this tutorial, we'll dive into the world of Docker Security, look at the attack surface of a Docker installation and show some straightforward container breakouts

Pomerium can be used as a native SSH reverse proxy, adding OAuth authentication and flexible Pomerium policy enforcement to standard SSH connections, without the need for tunnels, or custom clients or servers.
Learn how to quickly deploy your Python Django-based application to a remote Linux server under your control. This hands-on tutorial covers preparing and packaging a Django application from source code on your local machine and then deploying it to an Uncloud-managed machine, along with the networking ingress configuration and without using any external image registry.
Exploit a Kubernetes RBAC authorization bypass where nodes/proxy GET permissions allow command execution in any Pod.
Learn what a unikernel is and how it compares to a Linux container. Build and run your first unikernel inside a playground box.
