Infrastructure operations and data platform documentation.

Knowledge base for infrastructure platforms and compute workloads, including Proxmox, Ceph, PostgreSQL Cluster, Kubernetes, and HPC/CFD.

## Where to start

* To understand the overall environment, see [Overall architecture](/tran-quoc-van-or-technical-documentation/00.-overview/architecture.md).
* To deploy a platform, select a topic from the left-hand table of contents.
* For troubleshooting and command details, see the relevant technology guide.

## Documentation principles

* Every infrastructure change must update the related documentation.
* Every runbook must include prerequisites, commands, validation steps, and a rollback plan.
* Never commit secrets, passwords, tokens, or sensitive information to the repository.
