iximiuz Labs Challenges
Solve Linux, container and Kubernetes problems on real machines
iximiuz Labs Challenges are hands-on tasks on real Linux machines. Each one describes a problem, such as calling an HTTP API with curl, draining a Kubernetes node safely or recovering a node that is NotReady. You solve it in a playground, and the platform checks your solution automatically and gives hints and feedback.
