# Control Center Enhancements - Quick Start Guide

## What's New

The control-center has been enhanced with three major features:

1. **SSH Key Management** - Securely store and manage SSH keys with KMS encryption
2. **Mode-Based RBAC** - Four execution modes with role-based access control
3. **Platform Monitoring** - Real-time health monitoring for all platform services

## Quick Start

### 1. SSH Key Management

#### Store an SSH Key

```bash
# Using curl
curl -X POST http://localhost:8080/api/v1/kms/keys \
  -H "Authorization: Bearer $TOKEN" \
  -H "Content-Type: application/json" \
  -d '{
    "name": "production-server-key",
    "private_key": "-----BEGIN RSA PRIVATE KEY-----\n...\n-----END RSA PRIVATE KEY-----",
    "public_key": "ssh-rsa AAAA...",
    "purpose": "ServerAccess",
    "tags": ["production", "web-server"]
  }'

# Response
{
  "key_id": "550e8400-e29b-41d4-a716-446655440000",
  "fingerprint": "SHA256:abc123...",
  "created_at": "2025-10-06T10:00:00Z"
}
```

#### List SSH Keys

```bash

| **Solo** | Single developer | ❌ All admin | ❌ Optional |
| **MultiUser** | Small teams | ✅ Role-based | ⚠️ Optional |
| **CICD** | Automation | ✅ Service accounts | ✅ Mandatory |
| **Enterprise** | Production | ✅ Full RBAC | ✅ Mandatory |

#### Switch Execution Mode

```bash
# Development: Solo mode
curl -X POST http://localhost:8080/api/v1/mode \
  -H "Authorization: Bearer $TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"mode": "solo"}'

# Production: Enterprise mode
curl -X POST http://localhost:8080/api/v1/mode \

  -d '{"mode": "enterprise"}'
```

#### Assign Roles

```bash
# Make user an operator
curl -X POST http://localhost:8080/api/v1/rbac/users/john/role \
  -H "Authorization: Bearer $TOKEN" \

## Configuration

### config.defaults.toml

```toml
# SSH Key Management
[kms.ssh_keys]
rotation_enabled = true
rotation_interval_days = 90   # Rotate every 90 days
grace_period_days = 7          # 7-day grace period
auto_rotate = false            # Manual rotation only

# RBAC Configuration
[rbac]
enabled = true
mode = "solo"                  # solo, multi-user, cicd, enterprise
default_role = "viewer"        # Default for new users
admin_users = ["admin"]
allow_mode_switch = true
session_timeout_minutes = 60

# Platform Monitoring
[platform]
orchestrator_url = "http://localhost:8080"
coredns_url = "http://localhost:9153"
gitea_url = "http://localhost:3000"
oci_registry_url = "http://localhost:5000"
extension_registry_url = "http://localhost:8081"
provisioning_api_url = "http://localhost:8082"
check_interval_seconds = 30    # Health check every 30s
timeout_seconds = 5            # 5s timeout per check
```

## Use Cases

### Use Case 1: Developer Onboarding

```bash
# 1. Admin creates SSH key for new developer
curl -X POST http://localhost:8080/api/v1/kms/keys \
  -H "Authorization: Bearer $ADMIN_TOKEN" \
  -d '{
    "name": "john-dev-key",
    "purpose": "ServerAccess",
    "tags": ["developer", "john"]
  }'

# 2. Admin assigns developer role
curl -X POST http://localhost:8080/api/v1/rbac/users/john/role \
  -H "Authorization: Bearer $ADMIN_TOKEN" \
  -d '{"role": "developer"}'

# 3. John can now access dev/staging but not production
# His permissions are automatically enforced by RBAC middleware
```

### Use Case 2: CI/CD Pipeline

```bash
# 1. Switch to CICD mode
curl -X POST http://localhost:8080/api/v1/mode \
  -H "Authorization: Bearer $ADMIN_TOKEN" \
  -d '{"mode": "cicd"}'

# 2. Create service account SSH key
curl -X POST http://localhost:8080/api/v1/kms/keys \
  -H "Authorization: Bearer $SERVICE_TOKEN" \
  -d '{
    "name": "gitlab-ci-deploy-key",
    "purpose": "Automation",
    "tags": ["cicd", "gitlab"]
  }'

# 3. Service account can create/deploy but not delete
# All actions are logged for audit
```

### Use Case 3: Production Deployment

```bash
# 1. Switch to Enterprise mode (production)
curl -X POST http://localhost:8080/api/v1/mode \
  -H "Authorization: Bearer $ADMIN_TOKEN" \
  -d '{"mode": "enterprise"}'

# 2. Assign operator role to ops team
curl -X POST http://localhost:8080/api/v1/rbac/users/ops-team/role \
  -H "Authorization: Bearer $ADMIN_TOKEN" \
  -d '{"role": "operator"}'

# 3. Ops team can deploy, but all actions are audited
# Audit trail required for compliance (SOC2, PCI DSS)
```

### Use Case 4: Service Health Monitoring

```bash
# 1. Check all platform services
curl http://localhost:8080/api/v1/platform/services

# 2. Get notified if any service is unhealthy
# (Integrate with alerting system)

# 3. View service dependency graph
curl http://localhost:8080/api/v1/platform/dependencies

# 4. Identify which services are affected by outage
# (e.g., if database is down, Gitea will be degraded)
```

## Security Best Practices

### 1. SSH Keys

- ✅ **Use rotation**: Enable automatic rotation for production keys
- ✅ **Tag keys**: Use tags to organize keys by environment, purpose
- ✅ **Audit access**: Regularly review SSH key audit logs
- ✅ **Delete unused**: Remove SSH keys that haven't been used in 90+ days
- ⚠️ **Never expose**: Never log or display private keys

### 2. RBAC

- ✅ **Least privilege**: Default to Viewer role for new users
- ✅ **Enterprise mode**: Use Enterprise mode for production
- ✅ **Regular audits**: Review role assignments quarterly
- ✅ **Session timeout**: Use shorter timeouts (30 min) for Enterprise
- ⚠️ **Avoid Solo mode**: Never use Solo mode in production

### 3. Platform Monitoring

- ✅ **Set alerts**: Configure alerts for unhealthy services
- ✅ **Monitor dependencies**: Track service dependency health
- ✅ **Review metrics**: Check service metrics daily
- ✅ **Internal only**: Never expose service URLs externally
- ⚠️ **Timeout protection**: Use reasonable timeouts (5s default)

## Troubleshooting

### SSH Key Issues

**Problem**: "Key not found"
```bash
# Check if key exists
curl http://localhost:8080/api/v1/kms/keys | jq '.[] | select(.name=="my-key")'
```

**Problem**: "Permission denied to access key"
```bash
# Check your permissions
curl http://localhost:8080/api/v1/rbac/permissions | grep ssh_key
```

**Problem**: "Key rotation failed"
```bash
# Check rotation policy
cat config.toml | grep -A 5 "kms.ssh_keys"
```

### RBAC Issues

**Problem**: "Permission denied on API call"
```bash
# Check your role
curl http://localhost:8080/api/v1/rbac/permissions

# Check current mode
curl http://localhost:8080/api/v1/mode
```

**Problem**: "Cannot assign role"
```bash
# Only admins can assign roles
# Check if you have admin role
```

**Problem**: "Mode switch denied"
```bash
# Check if mode switching is allowed
cat config.toml | grep allow_mode_switch
```

### Platform Monitoring Issues

**Problem**: "Service shows as unhealthy"
```bash
# Check service directly
curl http://localhost:8080/health  # For orchestrator

# Check service logs
journalctl -u orchestrator -n 50
```

**Problem**: "Service health not updating"
```bash
# Check monitoring interval
cat config.toml | grep check_interval_seconds

# Verify platform monitor is running
ps aux | grep control-center
```

**Problem**: "Cannot start/stop service"
```bash
# Check permissions (requires Operator or Admin)
curl http://localhost:8080/api/v1/rbac/permissions | grep service
```

## Migration Guide

### From Existing SSH Key Storage

```bash
# 1. Export existing SSH keys
ls ~/.ssh/*.pub > key_list.txt

# 2. Import to KMS
while read key_file; do
  name=$(basename "$key_file" .pub)
  private_key=$(cat "${key_file%.pub}")
  public_key=$(cat "$key_file")

  curl -X POST http://localhost:8080/api/v1/kms/keys \
    -H "Authorization: Bearer $TOKEN" \
    -d "{
      \"name\": \"$name\",
      \"private_key\": \"$private_key\",
      \"public_key\": \"$public_key\",
      \"purpose\": \"ServerAccess\"
    }"
done < key_list.txt

# 3. Verify import
curl http://localhost:8080/api/v1/kms/keys
```

### From No RBAC to Enterprise Mode

```bash
# 1. Start in Solo mode (current default)
# config.toml: mode = "solo"

# 2. Create admin users
curl -X POST http://localhost:8080/api/v1/users \
  -d '{"username": "admin", "role": "admin"}'

# 3. Assign roles to existing users
curl -X POST http://localhost:8080/api/v1/rbac/users/john/role \
  -d '{"role": "developer"}'

curl -X POST http://localhost:8080/api/v1/rbac/users/ops/role \
  -d '{"role": "operator"}'

# 4. Switch to Multi-User mode (test)
curl -X POST http://localhost:8080/api/v1/mode \
  -d '{"mode": "multi-user"}'

# 5. Verify permissions work
# Test as different users

# 6. Switch to Enterprise mode (production)
curl -X POST http://localhost:8080/api/v1/mode \
  -d '{"mode": "enterprise"}'

# 7. Enable audit logging
# config.toml: [logging] audit_enabled = true
```
