# Operations cheatsheet

Run from the hubris host 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](../../../docs/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` Nomos cron — see [monitoring](../../../docs/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](../../../docs/infrastructure/media-permissions.md) for the GID-10000 onboarding recipe.

## Reverse proxy

- Caddyfile: `/etc/caddy/Caddyfile` on LXC 121.
- **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](../../../docs/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) 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](../../../docs/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)

## Fleet apt operations

**No current CLI equivalent.** `homelab apt-audit`/`apt-upgrade` (dpkg-state
audit, fanned-out apt upgrade with pre-upgrade snapshots) were part of the
retired Python `homelab` CLI and don't have a ported replacement — apt
patching today is ad hoc `run` MCP tool calls per host, without the
audit/snapshot/status wrapping this used to provide. If that wrapping is
still wanted, it needs to be rebuilt (e.g. as a runbook driving `run`, or a
new MCP tool) — see
[runbook-dpkg-interrupted](../skills/runbook-dpkg-interrupted/SKILL.md) for
the dpkg-interrupted recovery procedure specifically.

## Oikos (agent OS layer)

See [OIKOS.md](../OIKOS.md) for the operating model. The `homelab` CLI this
section used to document is retired; the actual current interface is the
MCP tool catalog in [AGENTS.md §3](../../AGENTS.md#3-the-mcp-server) plus
the REST API. Closest current equivalents for what used to live here:

| Old `homelab` command | Current equivalent |
| --- | --- |
| `homelab service <name> explain\|health\|docs\|log` | MCP `explain`, `get_service_status`, `tail_log`, `get_entity_knowledge` |
| `homelab node <name> relations` | MCP `get_blast_radius` |
| `homelab change preflight <service>` | MCP `preflight` |
| `homelab signal list\|ack\|resolve\|mute` | MCP `get_signal_history`, or REST `POST /api/v1/signals/{id}/ack\|resolve\|mute` (the control-room UI's Signals page wraps these) |
| `homelab approval request\|list\|reply\|check` | REST `GET/POST /api/v1/approvals*` (Matrix-delivered via the notifier, or the control-room UI's Operations page) |
| `homelab restart <service> --approval-id <id>` | MCP `run` (policy-gated — auto-executes if read-only/reversible_low, otherwise queues for the same Matrix/UI approval) |
| `homelab decide <action> <entity>` | No direct equivalent — classification now happens inline inside `run`, not as a separate dry-run call |

There is no separately-deployed "Oikos Console" anymore — the control-room
SPA is the operator dashboard. It lives in its own repo
(`dtoro/oikos-web`, local checkout `~/Projects/oikos-web`) with its own
deploy pipeline, publishing the same host port 8091 as before (Phase 1 of
[plans/2026-08-15-hexagonal-architecture.md](../../plans/2026-08-15-hexagonal-architecture.md)).
