# CLAUDE.md

This workspace is for managing PFI infrastructure — servers, Docker stacks, and related configs. Spawn a dedicated Claude Code session here when working on infra so it doesn't clutter AIPA-MCP development context.

**New session starting here?** Read [`docs/orientation.md`](docs/orientation.md) first — fleet topology, backup architecture, governing principles, and all the NFS/DSM/naming gotchas that have cost past sessions time.

**For SSH-driven work: use `scripts/elway`.** Write a playbook under
`playbooks/<name>.yaml` and run
`scripts/elway <host> --playbook ...` instead of chaining
`ssh -t host 'sudo …'` commands — handles sudo once lazily,
structured pass/change/fail reporting, idempotency via
`creates:` / `when:` / `changed_when:`. Template:
[`playbooks/elway-smoke.yaml`](playbooks/elway-smoke.yaml).

**Task visibility via task-board.** If the Claude Code session has
the `task-board` plugin enabled (installed from
`git@gitea.phasefinal.com:vh/task-board.git`), a card at
`http://10.250.50.70:7878/` tracks work in progress. Hooks flip the
card on turn boundaries automatically; call `task_start` /
`task_update` / `task_wait` / `task_complete` MCP tools to set the
activity subheader and post meaningful log entries.

## Purpose

- Inventory of servers and their state
- Canonical copies of Docker Compose stacks deployed on those servers
- Scripts for inspecting and managing the infrastructure
- Conventions so all stacks look the same

This is a **reference workspace** — the authoritative copies of compose files and configs live **on the servers** under `/opt/docker/compose/<stack>/` and `/opt/docker/conf/<stack>/`. This workspace mirrors them for version control, editing, and planning.

## Conventions (enforce for every new stack)

Observed and standardized across servers:

- **Compose location on server:** `/opt/docker/compose/<stack>/compose.yaml`
- **Config mounts on server:** `/opt/docker/conf/<stack>/...`
- **Networks:** external `traefik-net`, aliased as `tnet` in compose
  ```yaml
  networks:
    tnet:
      name: traefik-net
      external: true
  ```
- **GPU reservation:** prefer `deploy.resources.reservations.devices` with explicit `device_ids` for pinning
  ```yaml
  deploy:
    resources:
      reservations:
        devices:
          - driver: nvidia
            device_ids: ["1"]
            capabilities: [gpu]
  ```
- **Tunables:** `.env` in the same directory as `compose.yaml` — keep the compose file constant, edit the `.env`
- **Named volumes** for service state (pattern: `<stack>_<name>`)
- **Bind mounts** only for: model files (`/tank/aimodels/...`), config files (`/opt/docker/conf/...`), docker socket where required
- **Restart policy:** `restart: unless-stopped` for daemons
- **Homepage labels** on user-facing services:
  ```yaml
  labels:
    - homepage.group=AI Systems
    - homepage.name=<ServiceName>
    - homepage.icon=mdi-<icon>
    - homepage.description=<short>
    - homepage.href=http://<host-ip>:<port>
  ```
- **Healthchecks** on services that expose HTTP

**Placement rules:**
- GPU-required stacks → `ana-ml2` (primary, Anaheim) or `irv-ml1`
  (secondary, Irvine — bigger VRAM ceiling at 72 GB total). Access
  to `irv-ml1` requires WireGuard.
- Anaheim non-GPU services → `ana-docker`.
- NH-site non-GPU services → `nh3-docker`.
- ESH home-lab workloads (`esteban.net`) → `esh-docker-vm` (general) or `vm-esh-nas` (needs direct NFS mounts from 10.0.50.50). Not part of the PFI colo topology, but shares monitoring/backup tooling.
- Cross-site services (e.g. Beszel hub, Dozzle hub) live on `ana-docker` and pull from agents on the other hosts.
- **SureFire (SF) client hosts** (`sf-*`, `sfsrv-ana`) are PFI-managed under the hosting agreement — SSH, OS ops, backups are PFI's responsibility. Hardware and data belong to the client; coordinate anything that affects data with them.
- **Hypervisors** (`pfi-pve`, `nh3-pve`, `esh-pve`, `esh-pve-nas`) are tracked for inventory / capacity planning. Don't deploy Docker stacks directly on them; new workloads land as VMs. `server_inspect.sh` captures host-level detail only — VM/LXC/ZFS enumeration needs Proxmox-native tooling (`qm list`, `pvesh get …`, `zpool list`).

## How to refresh a server's state

```bash
# Show help (no args)
scripts/refresh-server-info.sh

# Refresh every host discovered under servers/*/
scripts/refresh-server-info.sh all

# Refresh a specific host (must match a servers/<name>/ dir; ssh_config
# entry or servers/<name>/ssh-target handles how to reach it)
scripts/refresh-server-info.sh ana-docker
```

Fleet-wide runs require the literal `all` keyword — no-args prints help so you can't accidentally hit every host by forgetting a name.

The script pipes `server_inspect.sh` over SSH via stdin (no scp, no remote cleanup) and writes each `servers/<host>/system-details.txt` atomically — a failed run never clobbers the previous snapshot. The inspect script itself is read-only.

Each server dir can hold an `ssh-target` file (one line, `<ip>` or `<user>@<ip>`) as a fallback for when the dir name doesn't resolve via DNS or `~/.ssh/config`. The script prefers whatever ssh would resolve normally and only consults the file when that fails.

To register a new server:

```bash
scripts/add-host.sh <name> <ip-or-user@ip>
scripts/refresh-server-info.sh <name>    # pull the first snapshot
```

To audit discovery without touching the network (checks permissions, unresolvable names with no fallback, missing README / system-details, malformed `ssh-target`):

```bash
scripts/refresh-server-info.sh --validate-only all
scripts/refresh-server-info.sh --validate-only <host>
```

## Stack tree convention (canonical vs mirror)

Two trees, distinct roles. **They are NOT interchangeable.**

| tree | role | git | who writes | who reads |
|---|---|---|---|---|
| `stacks/<stack>/` | **canonical / intent** — source of truth for what we want deployed | tracked | you / Claude | `deploy-stack.sh` |
| `stacks-mirror/<host>/<stack>/` | **snapshot / reality** — what's currently on each host | gitignored | `sync-stacks.sh` | drift inspection |

**Why two:** keeps "intent" (committed, reviewable, deployed) cleanly separate from "reality on the server right now" (often drifts, useful to compare, not durable). Editing the mirror does NOT affect what gets deployed.

```bash
# Edit the canonical, then push it to the host:
# stacks/<stack>/<file>      → /opt/docker/compose/<stack>/<file>
# stacks/<stack>/conf/<file> → /opt/docker/conf/<stack>/<file>
$EDITOR stacks/<stack>/compose.yaml
scripts/deploy-stack.sh <host> <stack>      # diffs vs live, prompts y/N
scripts/deploy-stack.sh <host> <stack> --compose   # skip conf side
scripts/deploy-stack.sh <host> <stack> --conf      # skip compose side

# Pull current host state into the gitignored snapshot tree (drift check):
scripts/sync-stacks.sh                     # every host
scripts/sync-stacks.sh ana-docker          # one host
scripts/sync-stacks.sh --dry-run           # see what would change

# Compare canonical (intent) vs mirror (reality) for one stack:
diff -ru stacks/<stack>/ stacks-mirror/<host>/<stack>/
```

**Opt-out per stack** (mirror only — sync-stacks.sh skip): create `stacks-mirror/<host>/<stack>/.no-sync` (skip both sides) or `stacks-mirror/<host>/<stack>/conf/.no-sync` (skip conf only).

**Always excluded in both directions** (secrets / runtime state): `.env`, `.env.*`, `acme.json`, `client_secrets.json`, `*.pem`, `*.key`, `*.crt`, `*.pfx`, `*.sqlite`, `*.sqlite3`, `*.db`, `*.log`, `*.log.*`, `*.pid`, `hub/`, `logs/`.

Requires `rsync` installed on this workstation and every host you sync against (`apt install rsync`).

## Working rules

- **Copies, not symlinks.** Files here reflect what's on the server at the time of the last sync. When you edit here, the server doesn't change until you deploy.
- **Never commit secrets.** Use `.env.example` templates; real `.env` files (with tokens, passwords) live on the server and are gitignored if/when this becomes a git repo.
- **Surgical edits.** When fixing one stack, don't touch unrelated ones. Follow AIPA-MCP's CLAUDE.md rules about scope discipline.
- **Sanity-check before deploying.** Run `docker compose config` (dry parse) before `docker compose up -d` on the server.
