Show HN: O3k – a lightweight OpenStack-compatible API for labs and tests (o3k.io)

What it is: A lightweight OpenStack-compatible environment for testing, learning, CI/CD, and edge labs.

What it is not: Not a production OpenStack replacement today. Not a full existing-cluster migration or upgrade tool.

Why we built it: OpenStack is powerful, but too heavy to quickly start, test, learn, or use in small automation scenarios.
