KubeFit / Flagship project · Publicly available · Free to use

Knowing isn’t doing.
Put in the reps.

My flagship project: a command-line trainer that turns Kubernetes and Linux study into timed, graded practice on your own machine. Concepts, playbooks, reports, and notebooks live at kubefit.com. Publicly available and free to use. Try a real drill without an account, then sign in to save progress.

The problem

Build the muscle.

Knowing the command is not the same as executing under pressure. KubeFit grew out of the gap between understanding Kubernetes and reliably diagnosing, fixing, and verifying a real system.

The approach / Terminal first

A training ground.

The website holds the concepts, playbooks, reports, and notebooks; the KubeFit CLI runs timed drills on your own machine. Kubernetes scenarios use local kind clusters, Linux drills use disposable Ubuntu VMs, and grading checks the actual system state. The portfolio now points to KubeFit instead of hosting a separate LMS.

Constraints / Evidence

The conditions shaped the system.

◆Closed-source and free to use; no invitation required
◆Practice runs on the learner’s own machine
◆Grading must verify outcomes, not recognize a particular solution
◆Independent project, unaffiliated with CNCF or The Linux Foundation
