Built for operators. Maintained in the open.
This repository contains practical command-line cheat sheets for operators working in OpenShift, Kubernetes-adjacent environments, and regulated enterprise systems.
These cheat sheets are designed to be:
- Quick reference — easy to scan when you just need the command
- Copy / paste friendly — no ceremony, no fluff
