K8s Mock Exam with CLI Syntax Checking

A mock exam tool to practice Kubernetes tasks (RBAC, node drain, upgrades) with real syntax checks for:

Kubernetes CLI: kubectl and kubeadm
Bash Commands: apt-get, systemctl, bash scripts
Partial Mock Outputs: For missing pipes or filters in certain commands
Persistent History: Command history across runs using arrow keys
Keyboard Shortcuts: Supports left/right arrow keys, Ctrl+A/E, and tab-completion

Features

Multi-Question Exam: 17 tasks covering Kubernetes scenarios
Command Aliases: Supports shorthand aliases for commands (e.g., k → kubectl, sa → serviceaccount).
Syntax Validation: Short timeout checks for valid flags and arguments
Help Support: Use commands like kubectl create --help to check usage
Error Handling: Displays real errors if commands fail validation
Persistent History: Commands persist across runs using history file
Keyboard Shortcuts: Enables Bash-like navigation with arrow keys and shortcuts

Clone & Run

git clone https://github.com/your-username/your-repo.git
cd your-repo
python main.py

Answer Questions
- Enter one command per line. Press Enter on a blank line to finalize.
- Use help commands anytime (e.g., kubectl --help).
Validate Answers
- Compare answers against references with flags/keywords.
- Mock outputs shown for commands requiring pipes or filters.

Safe Mode: Use a local cluster (kind/minikube) to avoid modifying real systems.
Timeouts: Default timeout is 2 seconds (adjustable in res/checks.py).
Persistent History: Commands are saved in ~/.k8s_mock_exam_history.
Arrow Key Support: Navigate left/right like a real CLI.

Happy Learning Kubernetes!
