## Overview

This repository is a hands-on CKAD practice lab, not an application runtime. A learner selects an exercise, runs its setup script against a Kubernetes cluster, reads the task, makes changes with kubectl, and runs the checker for validation and scoring; ANSWER.md provides a reference solution. The exercise collection spans workload design, deployment strategies, observability, configuration/security, and networking. Relationships below follow the README workflow and topic descriptions; individual scripts and exercise contents were not sampled.

Main entry points: [`Q01 - Create Secret from Hardcoded Variables/check.sh`](https://github.com/tariqm/ckad-2026/blob/main/Q01%20-%20Create%20Secret%20from%20Hardcoded%20Variables/check.sh) (Scoring checkers), [`Q01 - Create Secret from Hardcoded Variables/setup.sh`](https://github.com/tariqm/ckad-2026/blob/main/Q01%20-%20Create%20Secret%20from%20Hardcoded%20Variables/setup.sh) (Environment setup), [`Q01 - Create Secret from Hardcoded Variables/QUESTION.md`](https://github.com/tariqm/ckad-2026/blob/main/Q01%20-%20Create%20Secret%20from%20Hardcoded%20Variables/QUESTION.md) (Exercise prompts), [`Q01 - Create Secret from Hardcoded Variables/ANSWER.md`](https://github.com/tariqm/ckad-2026/blob/main/Q01%20-%20Create%20Secret%20from%20Hardcoded%20Variables/ANSWER.md) (Reference solutions)
