# Admin Instance Management System - Implementation Complete ✅

## Date: 2026-06-28

## Overview
Successfully implemented a comprehensive admin panel for managing Wakel AI instances with full lifecycle management, auto-deletion, and restore capabilities.

---

## ✅ Completed Features

### 1. Database Schema Updates
- ✅ Added `UserRole` enum (USER, ADMIN)
- ✅ Added `role` field to User model
- ✅ Created `AdminSettings` model with retention days configuration
- ✅ Added instance lifecycle fields to Instance model:
  - `deletedAt` - When instance was soft deleted
  - `scheduledDeletionDate` - When instance will be permanently deleted
  - `restoredAt` - When instance was restored
  - `deletedBy` - Admin who deleted the instance
  - `restoredBy` - Admin who restored the instance
- ✅ Added `DELETED` status to InstanceStatus enum

### 2. Admin Authentication & Authorization
- ✅ Created `/src/lib/admin-auth.ts` with admin helper functions
- ✅ Updated `/src/lib/auth.ts` to include role in JWT/session
- ✅ Updated `/src/middleware.ts` to check admin role for admin routes
- ✅ Updated NextAuth types in `/src/types/next-auth.d.ts`
- ✅ Created admin setup script `/scripts/setup-admin.ts`

### 3. Instance Lifecycle APIs
All APIs protected with admin role check:

- ✅ **GET `/api/admin/instances`** - List all instances with user info
- ✅ **POST `/api/admin/instances/[id]/stop`** - Stop instance and schedule deletion
- ✅ **POST `/api/admin/instances/[id]/delete`** - Soft delete instance
- ✅ **POST `/api/admin/instances/[id]/restore`** - Restore deleted/stopped instance
- ✅ **DELETE `/api/admin/instances/[id]/force-delete`** - Permanently delete instance
- ✅ **POST `/api/admin/instances/[id]/login-as-user`** - Admin impersonation

### 4. Admin Settings & Configuration
- ✅ **GET/PUT `/api/admin/settings/retention`** - Configure retention period (1-90 days, default 7)
- ✅ **GET `/api/admin/cron/auto-delete`** - Get deletion statistics
- ✅ **POST `/api/admin/cron/auto-delete`** - Trigger auto-deletion manually

### 5. Auto-Deletion Cron Job
- ✅ Created `/src/lib/cron/auto-delete-instances.ts`
- ✅ Automatically deletes instances past retention period
- ✅ Properly cleans up:
  - Docker containers
  - nginx configurations
  - Port allocations
  - Database records
- ✅ Can be triggered via external cron service with ADMIN_CRON_SECRET

### 6. Admin UI Components
- ✅ **Managed Instances Page** (`/src/app/admin/managed-instances/page.tsx`)
  - View all instances with full details
  - Filter by status (all, running, stopped, deleted)
  - Show created/deleted/scheduled deletion dates
  - Stop, delete, restore, force delete actions
  - Login as user functionality
  - Statistics cards (total, running, stopped, deleted, error, pending deletion)
  - Configurable retention period setting

- ✅ **Admin Settings Page** (`/src/app/admin/settings/page.tsx`)
  - Instance retention period configuration
  - Deletion statistics display
  - Auto-deletion cron configuration guide
  - Manual cron trigger button
  - System information display

### 7. Admin User Setup
- ✅ Promoted `ashraffarid@gmail.com` to ADMIN role
- ✅ Created default AdminSettings with 7 days retention

## 🔐 Security Features

1. **Role-Based Access Control**
   - All admin APIs require ADMIN role
   - Middleware protects admin routes
   - Fallback to ADMIN_EMAILS for backward compatibility

2. **Impersonation Security**
   - JWT-based impersonation tokens
   - 1-hour expiration
   - Audit logging in console

3. **Deletion Safety**
   - Soft delete by default
   - Confirmation required for force delete
   - Shows retention period before deletion

4. **Cron Security**
   - Requires ADMIN_CRON_SECRET
   - Supports both admin session and bearer token

---

## 🧪 Testing

### API Endpoints Tested:
- ✅ `/api/admin/instances` returns "Admin access required" without auth
- ✅ Application builds successfully
- ✅ Development server runs correctly

### Manual Testing Required:
- [ ] Login as admin user
- [ ] View all instances in admin panel
- [ ] Test stop instance action
- [ ] Test soft delete action
- [ ] Test restore action
- [ ] Test force delete action
- [ ] Test login as user
- [ ] Change retention period setting
- [ ] Test auto-deletion cron job
- [ ] Verify non-admin users cannot access admin functions

---

## 🚀 Deployment Instructions

### 1. Environment Variables
Add to `.env.local`:
```env
ADMIN_CRON_SECRET=your-secure-secret-key
```

### 2. Database Migration
Already applied using `prisma db push`.

### 3. Admin User Setup
```bash
npx tsx scripts/setup-admin.ts admin@example.com
```

### 4. Cron Job Setup
Add to your crontab or external cron service:
```bash
0 2 * * * curl -X POST https://wakelai.com/api/admin/cron/auto-delete -H "Authorization: Bearer YOUR_ADMIN_CRON_SECRET"
```

## 📊 Instance Lifecycle Flow

```
CREATING → RUNNING → STOPPED → DELETED → (permanent deletion after retention days)
                ↓         ↓         ↓
             (restore) (restore) (restore)
```

1. **Running Instance**: Can be stopped or soft deleted
2. **Stopped Instance**: 
   - Scheduled for deletion after retention period
   - Can be restored
3. **Deleted Instance**:
   - Marked as deleted but container kept
   - Scheduled for deletion after retention period
   - Can be restored
4. **Permanent Deletion**:
   - Docker container removed
   - nginx config deleted
   - Port released
   - Database record deleted

---

## 🎯 Usage Examples

### Stop an Instance
```bash
curl -X POST http://localhost:9100/api/admin/instances/{id}/stop \
  -H "Cookie: next-auth.session-token=..."
```

### Soft Delete an Instance
```bash
curl -X POST http://localhost:9100/api/admin/instances/{id}/delete \
  -H "Cookie: next-auth.session-token=..."
```

### Restore an Instance
```bash
curl -X POST http://localhost:9100/api/admin/instances/{id}/restore \
  -H "Cookie: next-auth.session-token=..."
```

### Force Delete Permanently
```bash
curl -X DELETE http://localhost:9100/api/admin/instances/{id}/force-delete \
  -H "Cookie: next-auth.session-token=..."
```

### Update Retention Period
```bash
curl -X PUT http://localhost:9100/api/admin/settings/retention \
  -H "Content-Type: application/json" \
  -H "Cookie: next-auth.session-token=..." \
  -d '{"days": 14}'
```

### Trigger Auto-Deletion
```bash
curl -X POST http://localhost:9100/api/admin/cron/auto-delete \
  -H "Authorization: Bearer YOUR_ADMIN_CRON_SECRET"
```

## 📝 Notes

1. **Retention Period**: Default is 7 days, configurable from 1-90 days
2. **Soft Delete**: Keeps Docker container running for easy restore
3. **Force Delete**: Permanent, cannot be undone
4. **Impersonation**: Creates 1-hour session for target user
5. **Audit Trail**: Logs admin actions (deleteBy, restoredBy)
6. **Statistics**: Real-time counts of instance states
