Docker 101: Run and Manage Containers
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.
Skill Paths
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.

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.
