Focused hands-on problems designed to help you hone your DevOps or Server Side skills. Some challenges are more educational, while others are based on real-world scenarios. The platform provides hints and feedback for each challenge, including automated solution checks.
Challenges crafted by iximiuz Labs to help you master DevOps and Server Side topics.
A new service needs to run in your development environment, but the port it requires is already in use by another app that has to keep working. Diagnose the conflict, free the port without taking the other app down, and get both services running side by side - a realistic exercise in untangling local port conflicts.
A systemd-managed worker process starts cleanly, prints a few heartbeat lines, then silently vanishes - over and over again. Diagnose why the process keeps dying and stabilize the service.
An image conversion daemon was installed from a vendor package, but it fails to start. Diagnose why the binary cannot be loaded and fix the installation.
A system daemon crashes on startup with a cryptic, non-actionable error message. Investigate the failure, identify its root cause, and get the service running.
Challenges contributed by the community members sharing their knowledge and expertise.
