homelab-topology-mapper

Name: homelab-topology-mapper
Rating: 56.00000000000001 (1 reviews)
Author: pvnkmnk

Produces a current-state map of the Proxmox homelab cluster. Enumerates all nodes, VMs (QEMU), LXC containers, storage pools, and network bridges. Output is used as the starting context for any change operation.

Invocation

OpenCode / Codex: Invoke homelab-topology-mapper Freebuff: /skill homelab-topology-mapper

Workflow Steps

Connect: Use mcp/proxmox-mcp.json to authenticate to Proxmox API.
List nodes: Enumerate all cluster nodes and their status.
List VMs: For each node, list all QEMU VMs (ID, name, status, CPU, RAM).
List containers: For each node, list all LXC containers (ID, name, status, CPU, RAM).
List storage: Enumerate storage pools with type, size, and usage.
List networks: Map network bridges and VLANs.
Output: Render topology as structured Markdown table.
Store: Optionally write snapshot to obsidian-homelab-logbook.

Output Format

## Nodes
| Node | Status | CPU | RAM |

## VMs
| ID | Name | Node | Status | CPU | RAM |

## Containers
| ID | Name | Node | Status | CPU | RAM |

## Storage
| Name | Type | Size | Used |

Verified Baseline (2026-09-18)

Last verified live topology — re-enumerate before acting, but use this as the sanity baseline:

Object	Value
Node	`proxmox` — PVE 9.2.11, `192.168.2.9`, tailnet `100.65.21.28` (i5-7200U 2c/4t, 8 GB, 1 TB 5400 RPM HDD)
Storage	`local` (14% used), `local-lvm` (25.6% used)
CT 101	`homelab-core` — `192.168.2.242`, tailnet `100.80.82.44`, 2 vCPU/4 GB (verify before changes), Navidrome + slskd + beets
Pool	`apppol`
Tailnet	`tail0ea6ba.ts.net`: `mvnk` (Windows PC, 100.69.36.47), `proxmox`, `homelab-core`, `ai`, `pixel-10`
Router	Bell Home Hub 3000, `192.168.2.1` — DNS filter NXDOMAINs reserved domains (example.com); account-level, not in hub UI

Rollback snapshot pre-dedup-20260917 covers CT 101 rootfs + music volume. Full detail: pvnkmnk/homelab-proxmox-ansible → docs/findings/2026-09-18-homelab-music-library-cleanup.md, plus docs/observed-state.md and docs/network-map.md there for the canonical topology.
