Manage TrueNAS SCALE via API. Check pool health, manage datasets and snapshots, monitor alerts, control services, manage apps, orchestrate Dockge container stacks, and manage bookmarks. Use when the user asks about their NAS, storage, backups, containers, bookmarks, or homelab services.

# TrueNAS SCALE Skill

Manage a TrueNAS SCALE server and its apps via the TrueNAS API and Dockge Socket.IO.

## Setup

### Required Environment Variables

```
TRUENAS_URL       — TrueNAS base URL (e.g., https://10.0.0.5:444)
TRUENAS_API_KEY   — API key from TrueNAS UI → API Keys

## API Notes

**HTTPS REQUIRED:** TrueNAS auto-revokes API keys used over HTTP.

> **REST API Deprecation Notice:** The REST API (`/api/v2.0/`) is deprecated in TrueNAS 25.04
> and **fully removed in 26.04**. Use the WebSocket API (via `scripts/truenas-ws.mjs`) as
> the forward-compatible method. REST examples below still work on 24.10 and 25.x.

### REST API (Legacy)

```bash
curl -sk "$TRUENAS_URL/api/v2.0/[endpoint]" \
  -H "Authorization: Bearer $TRUENAS_API_KEY"
```

The `-k` flag is needed for self-signed certificates (common on home servers).

### WebSocket API (Recommended)

The WebSocket API uses a DDP-like protocol (Meteor style). REST paths become dot notation:
`/api/v2.0/app` → `app.query`, `/api/v2.0/system/info` → `system.info`.

```javascript
// Connect: wss://<host>/websocket (rejectUnauthorized: false for self-signed)

// 1. Handshake
send: {"msg": "connect", "version": "1", "support": ["1"]}
recv: {"msg": "connected", "session": "..."}

// 2. Authenticate
send: {"id": "1", "msg": "method", "method": "auth.login_with_api_key", "params": ["API_KEY"]}
recv: {"id": "1", "msg": "result", "result": true}

// 3. Call methods
send: {"id": "2", "msg": "method", "method": "system.info", "params": []}
send: {"id": "3", "msg": "method", "method": "app.query", "params": []}
```

Use the helper script for WebSocket calls: `node scripts/truenas-ws.mjs <method> [params_json]`

## Security Notes

- **Self-signed certificates:** TLS verification is skipped by default (`curl -k`, `rejectUnauthorized: false`) because homelab servers typically use self-signed certs. Set `TRUENAS_VERIFY_TLS=1` to enforce strict TLS validation.
- **API key scope:** Use a read-only or least-privilege API key when possible. TrueNAS lets you scope keys to specific endpoints.
- **Credentials stay local:** All env vars are read at runtime and sent only to the configured service endpoints. Nothing is phoned home.

## Core Operations

### System Info

```bash
curl -sk "$TRUENAS_URL/api/v2.0/system/info" -H "Authorization: Bearer $TRUENAS_API_KEY"
```

### Pool Health

```bash
# All pools with health status
curl -sk "$TRUENAS_URL/api/v2.0/pool" -H "Authorization: Bearer $TRUENAS_API_KEY" \
  | jq '.[] | {name, healthy}'

# Or via WebSocket
node scripts/truenas-ws.mjs pool.query '[]'
```

The API returns a `.healthy` boolean per pool. For deeper status, inspect the full pool object.

### Active Alerts

```bash
curl -sk "$TRUENAS_URL/api/v2.0/alert/list" -H "Authorization: Bearer $TRUENAS_API_KEY" \
  | jq '.[] | {level, formatted}'
```

### Running Services

```bash
curl -sk "$TRUENAS_URL/api/v2.0/service" -H "Authorization: Bearer $TRUENAS_API_KEY" \
  | jq '.[] | select(.state == "RUNNING") | .service'
```

## Dataset Management

### List Datasets

```bash
curl -sk "$TRUENAS_URL/api/v2.0/pool/dataset" -H "Authorization: Bearer $TRUENAS_API_KEY" \
  | jq '.[] | {name, type, used: .used.parsed, available: .available.parsed}'
```

### Create Dataset

```bash
curl -sk -X POST "$TRUENAS_URL/api/v2.0/pool/dataset" \
  -H "Authorization: Bearer $TRUENAS_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"name": "pool/path/new-dataset"}'
```

### Delete Dataset

```bash
# Destructive — confirm with user first
curl -sk -X DELETE "$TRUENAS_URL/api/v2.0/pool/dataset/id/DATASET_ID" \
  -H "Authorization: Bearer $TRUENAS_API_KEY"
```

## Snapshots & Replication

### List Snapshots

```bash
# WebSocket (required on 25.10+, /api/v2.0/zfs/snapshot returns 404)
node scripts/truenas-ws.mjs zfs.snapshot.query '[]'
```

### Create Snapshot

```bash
node scripts/truenas-ws.mjs zfs.snapshot.create '[{"dataset": "pool/dataset", "name": "manual-YYYY-MM-DD"}]'
```

### Snapshot Task Status

```bash
curl -sk "$TRUENAS_URL/api/v2.0/pool/snapshottask" -H "Authorization: Bearer $TRUENAS_API_KEY" \
  | jq '.[] | {dataset, schedule, enabled}'
```

### Replication Health

```bash
curl -sk "$TRUENAS_URL/api/v2.0/replication" -H "Authorization: Bearer $TRUENAS_API_KEY" \
  | jq '.[] | {name, state: .state.state}'
```

## App Management

TrueNAS Apps are the official marketplace for installing containerized services.

### List Installed Apps

```bash
curl -sk "$TRUENAS_URL/api/v2.0/app" -H "Authorization: Bearer $TRUENAS_API_KEY" \
  | jq '.[] | {name, state, version}'
```

### Check for Updates

```bash
curl -sk "$TRUENAS_URL/api/v2.0/app" -H "Authorization: Bearer $TRUENAS_API_KEY" \
  | jq '.[] | select(.upgrade_available) | .name'
```

### Install / Update Apps

See `references/app-installation.md` for the full installation guide covering:
- Checking app templates and storage requirements
- Creating datasets with proper ACLs
- Installing with correct storage mappings
- Handling apps with multiple storage mounts

### App Status

```bash
curl -sk "$TRUENAS_URL/api/v2.0/app?name=APP_NAME" -H "Authorization: Bearer $TRUENAS_API_KEY" \
  | jq '.[0] | {name, state, portals}'
```

## Dockge (Docker Compose Stacks)

Dockge is a companion UI for Docker Compose stacks not in the TrueNAS Apps catalog.
It uses Socket.IO, not REST. Use the provided scripts.

### Prerequisites

```bash
npm install   # in this skill's root directory
```

### List Stacks

```bash
node scripts/dockge-list.mjs
```

### Update Stacks

```bash
# Update all running stacks
node scripts/dockge-update.mjs

# Update specific stacks
node scripts/dockge-update.mjs mystack1 mystack2
```

### Socket.IO Protocol Details

Dockge uses Socket.IO with WebSocket transport.

**Status codes:**
- 1 = inactive/exited
- 3 = running
- 4 = updating

**Key events:**
- `login` — authenticate with username/password
- `stackList` — get all stacks (received via `agent` event)
- `agent`, "", "updateStack", stackName — trigger pull + restart

**Note:** Stacks prefixed with `ix-` are TrueNAS-managed apps visible to Dockge — skip those when updating.

## Monitoring Checklist

Run these commands for a quick health overview:
