# Infrastructure Inventory

Centralized inventory and discovery system for all infrastructure components in Sankofa Phoenix.

## Overview

The infrastructure inventory system provides:
- Auto-discovery of infrastructure components
- Centralized inventory database
- Asset tracking and lifecycle management
- Configuration drift detection
- Change history and audit trails

## Components

### Discovery (`discovery/`)

Auto-discovery scripts for:
- Proxmox clusters and nodes
- Network devices (switches, routers)
- Omada controllers and access points
- Storage systems
- Other infrastructure components

### Database (`database/`)

Inventory database schema and management:
- PostgreSQL schema for inventory
- Migration scripts
- Query utilities
- Backup/restore procedures

## Discovery

### Auto-Discovery

```bash
# Discover all infrastructure
./discovery/discover-all.sh --site us-east-1

# Discover Proxmox infrastructure
./discovery/discover-proxmox.sh --site us-east-1

# Discover network infrastructure
./discovery/discover-network.sh --site us-east-1

# Discover Omada infrastructure
./discovery/discover-omada.sh --controller omada.sankofa.nexus
```

### Scheduled Discovery

Discovery can be scheduled via cron or Kubernetes CronJob:

```yaml
apiVersion: batch/v1
kind: CronJob
metadata:
  name: infrastructure-discovery
spec:
  schedule: "0 */6 * * *"  # Every 6 hours
  jobTemplate:
    spec:
      template:
        spec:
          containers:
          - name: discovery
            image: infrastructure-discovery:latest
            command: ["./discovery/discover-all.sh"]
```

## Database Schema

### Tables

- **sites**: Physical sites/locations
- **nodes**: Compute nodes (Proxmox, Kubernetes)
- **vms**: Virtual machines
- **network_devices**: Switches, routers, access points
- **storage_pools**: Storage systems
- **networks**: Network segments and VLANs
- **inventory_history**: Change history

### Schema Location

See `database/schema.sql` for complete database schema.

## Usage

### Query Inventory

```bash
# List all sites
./database/query.sh "SELECT * FROM sites"

# List nodes for a site
./database/query.sh "SELECT * FROM nodes WHERE site_id = 'us-east-1'"

# Get VM inventory
./database/query.sh "SELECT * FROM vms WHERE site_id = 'us-east-1'"
```

### Update Inventory

```bash
# Update node information
./database/update-node.sh \
  --node pve1 \
  --site us-east-1 \
  --status online \
  --cpu 32 \
  --memory 128GB
```

### Configuration Drift Detection

```bash
# Detect configuration drift
./discovery/detect-drift.sh --site us-east-1

# Compare with expected configuration
./discovery/compare-config.sh \
  --site us-east-1 \
  --expected expected-config.yaml
```

## Integration

### API Integration

The inventory system provides a REST API for integration:

```bash
# Get site inventory
curl https://api.sankofa.nexus/inventory/sites/us-east-1

# Get node details
curl https://api.sankofa.nexus/inventory/nodes/pve1

# Update inventory
curl -X POST https://api.sankofa.nexus/inventory/nodes \
  -H "Content-Type: application/json" \
  -d '{"name": "pve1", "site": "us-east-1", ...}'
```

### Portal Integration

The inventory is accessible via the Portal UI:
- Infrastructure explorer
- Asset management
- Configuration comparison
- Change history

## Configuration

### Discovery Configuration

```yaml
discovery:
  sites:
    - id: us-east-1
      proxmox:
        endpoints:
          - https://pve1.sankofa.nexus:8006
          - https://pve2.sankofa.nexus:8006
      network:
        snmp_community: public
        devices:
          - 10.1.0.1  # switch-01
          - 10.1.0.254  # router-01
      omada:
        controller: omada.sankofa.nexus
        site_id: us-east-1
```

### Database Configuration

```yaml
database:
  host: postgres.inventory.svc.cluster.local
  port: 5432
  database: infrastructure
  username: inventory
  password: ${DB_PASSWORD}
  ssl_mode: require
```

## Backup and Recovery

### Backup Inventory

```bash
# Backup inventory database
./database/backup.sh --output inventory-backup-$(date +%Y%m%d).sql
```

### Restore Inventory

```bash
# Restore inventory database
./database/restore.sh --backup inventory-backup-20240101.sql
```

## Reporting

### Generate Reports

```bash
# Generate inventory report
./database/report.sh --site us-east-1 --format html

# Generate asset report
./database/asset-report.sh --format csv
```
