Reference

Material you reach for when you are operating systems, not learning them.

Production Architecture — how the tools in this portal connect in a real production environment. Reference diagrams for a full Kubernetes delivery stack.

Troubleshooting Playbook — a diagnostic guide for production failures. Organized by symptom, layered from OS to application. Use this when something breaks and you need to know where to start.

Cheatsheets — every command you will actually use, grouped by what you are trying to do. One page per tool: Linux, Git, Docker, kubectl, Helm, Terraform, and ArgoCD.
