Infrastructure CLI Emulator
Web-based terminal simulating kubectl, docker, and terraform commands
The Problem
Onboarding engineers on production clusters created operational risks and configuration drift. Provisioning isolated cloud sandboxes cost $800 monthly per engineer and required ongoing maintenance.
The Approach
I built a web-based terminal simulating kubectl, docker, terraform, and custom infrastructure CLI commands. Responses mirror real production outputs using sanitized data from actual clusters. Supports command history with arrow keys, tab completion hints, and nine command categories. The emulator validates commands against real syntax so engineers learn proper flags.
The Result
Onboarding time decreased from two weeks to three days, eliminating sandbox infrastructure costs while keeping production access restricted until training completion.
