Curated lists of practical challenges sprinkled with a little bit of theory and lots of colorful diagrams to help you learn more efficiently. Skill paths are ultra focused learning series which you can use to develop or improve a specific skill: container networking troubleshooting, image building, etc.
Skill paths crafted by iximiuz Labs to help you master DevOps and Server Side topics.
Practice the most common Linux storage operations in a series of hands-on challenges: discover and mount drives, create partition tables, format partitions with different filesystems, map directories with bind mounts, and make mount points survive a reboot.
Learn how to reach an internal port on a remote machine from the local system, jump through a bastion into a private VPC, expose a development server to the Internet through a reverse tunnel, publish a home network device, and spin up a full-fledged SOCKS proxy with nothing but a regular SSH connection.
Go from zero to a confident Docker beginner. Learn how to run containers of all kinds, interact with them, and build a clear mental model of how Docker manages your applications behind the scenes.
Learn how to write Dockerfiles from scratch and build production-ready container images. Start with the basics of image building and progress through handling dependencies, compiling applications, inspecting image internals, and optimizing builds with multi-stage Dockerfiles. Then go deeper with advanced Dockerfile instructions, analyzing image internals, and producing multi-platform builds.

A hands-on guide to building a minimal service mesh using eBPF and Envoy, focusing on transparent traffic interception and the core mechanics behind policy, observability, and encryption.
A hands-on learning path that teaches how to use eBPF and XDP for high-performance, in-kernel packet processing, from protocol parsing to advanced use cases like firewalling, rate limiting, and load balancing.
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.

Four hands-on challenges covering the full storage stack. Start with emptyDir, move to dynamic provisioning with StorageClass, explore static PV binding patterns including label selectors, bidirectional claimRef, and topology-aware local volumes, then finish with PV reclaim policies and data recovery.
Nine hands-on challenges split into two sections. The resource section covers how requests, QoS classes, priority, and namespace quotas shape scheduling decisions. The placement section covers how affinity, topology spread, and dedicated nodes control where pods land. HPA closes the path by showing how requests drive autoscaling.
Skill paths prepared by software vendors to help you learn and experiment with their products and services.
Master database management on Kubernetes with KubeBlocks! This path covers setup, auto-tuning, deployment, upgrades, backups, monitoring, and optimization across five tutorials, all aligned with Operator Capability levels.
