Problem: node and cross-cutting narratives lived at the repo root
(containers/, vms/, infrastructure/, host .md files), interleaved with the
machine-readable substrate.
Change:
- Move containers/ -> knowledge/wiki/containers/, vms/ -> knowledge/wiki/vms/,
infrastructure/ -> knowledge/wiki/infrastructure/, hosts/{hubris,strong}.md ->
knowledge/wiki/hosts/, infrastructure/references/ -> knowledge/sources/references/,
GLOSSARY.md -> knowledge/GLOSSARY.md.
- Add knowledge/{index.md,log.md,sources/index.md} scaffolding.
- Rewrite all relative links repo-wide via a path-resolving mapper (inbound +
outbound + between-moved-files), including .hermes/, runbooks, operations,
investigations, plans, README, AGENTS.
- Repoint inventory.yaml doc_page fields and regenerate hosts/*.yaml (which
embed doc_page); update oikos/gen-topology.py output path, candidate doc
paths, and footer links; update code-comment doc paths.
Substrate untouched in place: inventory.yaml, hosts/*.yaml (regenerated,
idempotent), oikos/ code, mcp/, secrets/, bin/.
Verification:
- Logical broken-link set identical to pre-move baseline (net 128 -> 127; the
topology regen fixed one, introduced none). Remaining are pre-existing refs
to destroyed/archived nodes, out of scope for this move.
- gen-topology.py --check exit 0 (in sync); cards carry knowledge/wiki/ doc paths.
- build_host_files.py idempotent; all inventory doc_page targets resolve.
- MCP contract verified: get_page/search_docs/get_changelog resolve moved pages.

# Operations cheatsheet
|
||
|
||
Run from the [hubris host](../knowledge/wiki/hosts/hubris.md) as root. When working from `/root` on Linux you're already on hubris — don't `ssh hubris` / `ping hubris`.
|
||
|
||
## Proxmox CLI
|
||
|
||
| Command | Use |
|
||
| --- | --- |
|
||
| `pct list` / `qm list` | List LXC containers / VMs |
|
||
| `pct config <id>` / `qm config <id>` | Container / VM config |
|
||
| `pct exec <id> -- <cmd>` | Run command inside an LXC without entering it (no initgroups — see [media permissions](../knowledge/wiki/infrastructure/media-permissions.md)) |
|
||
| `pct enter <id>` | Shell into a container |
|
||
| `pct start <id>` / `pct stop <id>` | Boot / halt a container |
|
||
| `pvesm status` | Storage pools status |
|
||
| `pvesh get /nodes --output-format json` | Node summary as JSON |
|
||
| `pvesh get /nodes/hubris/lxc/<id>/status/current` | Live container status |
|
||
| `pvesh get /cluster/resources --type vm --output-format json` | Bulk per-LXC CPU/mem/disk (used by the `homelab-health-watchdog` Hermes cron — see [monitoring](../knowledge/wiki/infrastructure/monitoring.md); the old `claudio-monitor` this once fed is deprecated) |
|
||
| `pveversion` | PVE version |
|
||
| `journalctl -u pve-cluster -n 100` | PVE service logs |
|
||
|
||
## Storage
|
||
|
||
- Shared mount: `/mnt/library` (ext4 on lvmthin `library`).
|
||
- Bind into a container: `pct set <id> -mp<N> /mnt/library/<sub>,mp=/data`
|
||
- For the standard whole-tree mount: `pct set <id> -mp0 /mnt/library,mp=/mnt/library`. See [media permissions](../knowledge/wiki/infrastructure/media-permissions.md) for the GID-10000 onboarding recipe.
|
||
|
||
## Reverse proxy
|
||
|
||
- Caddyfile: `/etc/caddy/Caddyfile` on [LXC 121](../knowledge/wiki/containers/121-caddy.md).
|
||
- **CRITICAL:** This file is tracked in `dtoro/caddy-conf` (https://git.hubris.network/dtoro/caddy-conf). Never edit it directly on the LXC — commit + push to the repo instead. Caddy auto-deploys on push (see [auto-deploy](../knowledge/wiki/infrastructure/auto-deploy.md)). If you edit directly, the change will be lost on the next pull and agents won't know about it.
|
||
- Hot reload: `pct exec 121 -- systemctl reload caddy`.
|
||
- Validate: `pct exec 121 -- caddy validate --config /etc/caddy/Caddyfile`.
|
||
- Git workflow shortcut: `pct exec 121 -- "cd /etc/caddy && git add Caddyfile && git commit -m '...' && git push"`.
|
||
|
||
## DNS
|
||
|
||
- Split-horizon authority: [Technitium DNS](https://technitium.com) on [dns (107)](../knowledge/wiki/containers/107-dns.md) at `192.168.8.2:53`. Web UI at `http://192.168.8.2`. (Formerly dnsmasq on the now-destroyed LXC 124 — decommissioned 2026-06-04.)
|
||
- Add/edit records in the Technitium UI; the NetBird managed zone sync (`scripts/dns-sync.py` cron on 107) picks changes up within ~10 minutes.
|
||
- Verify: `dig @192.168.8.2 +short <host>.hubris.network`.
|
||
- See [DNS](../knowledge/wiki/infrastructure/dns.md).
|
||
|
||
## Web access
|
||
|
||
- `https://proxmox.hubris.network` or `https://192.168.8.77:8006` — Proxmox UI
|
||
|
||
## Telemetry quick checks
|
||
|
||
- `ras-mc-ctl --summary` — summary of any RAS events (memory / PCIe AER / thermal) since boot
|
||
- `ras-mc-ctl --errors` — full event log
|
||
- `cat /sys/devices/system/cpu/cpu0/cpufreq/energy_performance_preference` — should be `balance_power`
|
||
- `cat /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor` — should be `powersave`
|
||
- `ls /sys/fs/pstore/ /var/lib/systemd/pstore/` — panic traces from a previous crash (empty for pure hardware hangs — see [investigation](../investigations/2026-04-21-hubris-crash-loop.md))
|
||
|
||
## Fleet apt operations
|
||
|
||
Two `homelab` subcommands wrap the common patterns; both fan out to hubris + every LXC.
|
||
|
||
| Command | What it does |
|
||
| --- | --- |
|
||
| `homelab apt-audit [--target HOST]` | Per-host table: dpkg-interrupted state, holds, upgradable count, non-apt binaries in system paths, DNS health. Exits nonzero if any host has dpkg-interrupted state. |
|
||
| `homelab apt-upgrade --target HOST` | Launch `apt update && apt upgrade` inside a transient `systemd-run --collect` unit on the target. Survives ssh teardown. Apt configured with `Acquire::Retries=3` + `ForceIPv4=true`. |
|
||
| `homelab apt-upgrade --all` | Same, fanned out across the standard targets. |
|
||
| `homelab apt-upgrade ... --status` | Show running unit + tail `/var/log/homelab-apt-upgrade.log` on each target. |
|
||
| `homelab apt-upgrade ... --safe` | Take a pre-upgrade snapshot per LXC first (`pct snapshot` → `vzdump` fallback for bind-mounted LXCs). Refuses if any snapshot fails unless `--force`. |
|
||
| `homelab apt-upgrade ... --force` | Skip both the dpkg-audit gate and snapshot-failure refusal. |
|
||
|
||
PVE/kernel deferral on hubris: `homelab apt-upgrade --target hubris` will try every upgrade, including kernel + `pve-*`. To skip those, `apt-mark hold` the relevant packages on hubris first; `homelab apt-audit` shows held packages so you can confirm.
|
||
|
||
## Oikos (agent OS layer)
|
||
|
||
See [OIKOS.md](../OIKOS.md) for the operating model. Quick reference:
|
||
|
||
| Command | What it does |
|
||
| --- | --- |
|
||
| `homelab service <name> explain\|health\|docs\|log\|actions\|history` | Service Console v0 — context card, cached health (`--live` to force a probe), docs, logs, safe actions + risk class, ledger history |
|
||
| `homelab node <name> relations` | Ontology blast-radius query: what this host/service impacts, is affected by, and its full transitive blast radius |
|
||
| `homelab change preflight <service>` | Dry-run report before mutating: risk class, current health, config repo, verification command |
|
||
| `homelab decide <action> <entity>` | Decision classifier: risk × blast radius × confidence → auto-act or escalate |
|
||
| `homelab signal list\|raise\|ack\|resolve\|mute` | The attention layer — pending updates, thresholds, drift, anything needing attention |
|
||
| `homelab approval request\|list\|reply\|check` | Escalate-route grants (Matrix-delivered via Hermes, or the Oikos Console's `/approvals` page) |
|
||
| `homelab restart <service> [--approval-id <id>]` | `--approval-id` is required whenever the service's risk class needs approval (e.g. `caddy`, `dns`) — refuses mechanically without a valid grant |
|
||
|
||
Oikos Console (read-mostly dashboard): `oikos.hubris.network` once deployed — see [oikos/console/deploy/README.md](../oikos/console/deploy/README.md).
