- 📦 **Easy Installation**: Automated setup with deployment profiles

## 🚀 Quick Start

Choose your deployment scenario:

### 📋 Common Steps (All Deployments)

#### Step 1: Setup OpenStack Resources
```bash
pip install octavia-loxilb-driver
# Run automated setup to create networks, flavors, and security groups
octavia-loxilb-setup
```

#### Step 2: Download and Upload LoxiLB VM Image
```bash
# Download LoxiLB VM image from releases
wget https://github.com/NLX-SeokHwanKong/octavia-loxilb-driver/releases/download/vm-v1.0.0/loxilb-vm-standard-v1.0.0.qcow2.gz

# Extract and upload to OpenStack with loxilb tag and performance properties
gunzip loxilb-vm-standard-v1.0.0.qcow2.gz
openstack image create --disk-format qcow2 --container-format bare \
    --public --tag loxilb \
    --property hw_vif_multiqueue_enabled=True \
    --property hw_vif_model=virtio \
    --property hw_disk_bus=virtio \
    --property hw_video_model=virtio \
    --property os_distro=ubuntu \
    --property os_type=linux \
    --file loxilb-vm-standard-v1.0.0.qcow2 loxilb-vm-standard

# Note: hw_vif_multiqueue_enabled=True is critical for LoxiLB performance
# It enables multiple queue networking for high-throughput packet processing
```

---

### 🖥️ Traditional OpenStack (systemd services)

#### Step 3: Install Driver on Controller Node
```bash
# Install on the controller node where Octavia services run
pip install octavia-loxilb-driver
```

#### Step 4: Configure Octavia
```bash
# Edit /etc/octavia/octavia.conf and add the generated configuration
sudo vim /etc/octavia/octavia.conf
```

#### Step 5: Restart Services
```bash
sudo systemctl restart octavia-api octavia-worker octavia-controller
```

---

### 🐳 Containerized Deployments

#### For Kolla-Ansible:
```bash
# Step 3: Install in Octavia containers
sudo docker exec octavia_api pip install octavia-loxilb-driver
sudo docker exec octavia_worker pip install octavia-loxilb-driver
sudo docker exec octavia_controller pip install octavia-loxilb-driver

# Step 4: Update kolla configuration
# Add to /etc/kolla/octavia-api/octavia.conf
# Add to /etc/kolla/octavia-worker/octavia.conf  
# Add to /etc/kolla/octavia-controller/octavia.conf

# Step 5: Restart containers
sudo docker restart octavia_api octavia_worker octavia_controller
```

#### For OpenStack-Helm (Kubernetes):
```bash
# Step 3: Update helm values to include the driver
# Add to values.yaml:
# conf:
#   octavia:
#     api_settings:
#       enabled_provider_drivers: amphora:amphora,loxilb:loxilb

# Step 4: Upgrade helm release
helm upgrade octavia ./octavia --values=values.yaml
```

#### For TripleO:
```bash
# Step 3: Add to container customization
# Create custom container image with the driver pre-installed
# Or use ExtraConfig to install during deployment
```

---

### 🔧 DevStack Environment

#### Step 3: Install in DevStack
```bash
# Install in devstack environment
source ~/devstack/openrc admin admin
pip install octavia-loxilb-driver

# Configure in local.conf for persistent setup
echo "pip install octavia-loxilb-driver" >> ~/devstack/local.sh
```

---

### ✅ Verification (All Deployments)
```bash
# Verify provider is available
openstack loadbalancer provider list

# Create your first LoxiLB load balancer
openstack loadbalancer create --provider loxilb --subnet-id <SUBNET_ID> my-lb
```

**Note**: For containerized deployments, you may need to rebuild container images or use persistent volume mounts to ensure the driver survives container restarts.

## 📋 Prerequisites

- **OpenStack**: Zed or later with Octavia service
- **Python**: 3.8+ with pip
- **Access**: OpenStack admin credentials and sudo access
- **Resources**: Available compute and network quotas
- **LoxiLB VM Image**: Downloaded from GitHub releases
- **Manual Configuration**: Octavia configuration file editing required

## 🏗️ Architecture

The LoxiLB Octavia Driver is a Software Load Balancer (SLB) that dynamically provisions LoxiLB VMs for each load balancer:

```
┌─────────────────┐    ┌──────────────────┐    ┌─────────────────┐
│   Octavia API   │───▶│  LoxiLB Driver   │───▶│ Dynamic LoxiLB VMs 
│ (Per Load Balancer)  │                  |    |                 |
└─────────────────┘    └──────────────────┘    └─────────────────┘
                               │
                               ▼
                    ┌──────────────────┐
                    │  OpenStack VMs   │
                    │ (LoxiLB Instance)│
                    └──────────────────┘
```

**Key Components:**
- **Provider Driver**: Main integration with Octavia API
- **LoxiLB API Client**: High-performance API communication with retry logic
- **Resource Mapping**: ID translation between Octavia and LoxiLB
- **Health Monitoring**: Coordinated health checking
- **State Reconciliation**: Ensures data consistency

## ⚡ Deployment Profiles

Choose the right profile for your environment:

| Profile | Use Case | Resources | Command |
|---------|----------|-----------|---------|
| **DevStack** | Development & Testing | 1 vCPU, 4GB RAM | `octavia-loxilb-setup --deployment-type devstack` |
| **Standard** | Standard Production | 2 vCPU, 8GB RAM | `octavia-loxilb-setup` (default) |
| **Production** | High Performance | 4 vCPU, 16GB RAM | `octavia-loxilb-setup --deployment-type production` |

## 🔧 Custom Configuration

For advanced deployments, create a JSON configuration file:

```json
{
  "flavor": {
    "name": "custom-loxilb-flavor",
    "vcpus": 2,
    "ram": 4096,
    "disk": 30
  },
  "network": {
    "name": "custom-mgmt-network",
    "cidr": "172.16.100.0/24"
  }
}
```

Use with: `octavia-loxilb-setup --custom-config config.json`

## 📊 Performance Benefits

Compared to traditional software load balancers:

- **10x Lower Latency**: eBPF/XDP processing in kernel space
- **50% Less CPU Usage**: Efficient packet processing without userspace overhead
- **Higher Throughput**: Multi-million packets per second capability
- **Better Scaling**: Linear performance scaling with additional cores

## 🌐 Network Architecture

### Management Network
- **Purpose**: Octavia controller ↔ LoxiLB VM communication
- **Default**: `octavia-mgmt-net` (192.168.1.0/24)
- **Ports**: 8091 (API), 9443 (BGP), 11111/22222 (HA)

### Data Networks
- **Purpose**: User traffic load balancing
- **Integration**: Works with existing tenant networks
- **Protocols**: TCP, UDP, HTTP, HTTPS with L4/L7 load balancing

## 🛠️ Deployment-Specific Installation

### 🖥️ Traditional OpenStack (Bare Metal/VMs)
```bash

    sudo docker exec $container pip install octavia-loxilb-driver
done

# Method 2: Persistent installation via kolla customization
# Add to /etc/kolla/kolla-build.conf:
# [octavia-base]
# pip_packages = octavia-loxilb-driver

# Rebuild containers:
# kolla-build octavia
```

### ☸️ OpenStack-Helm (Kubernetes)
```yaml
# Add to helm values.yaml
images:
  tags:
    octavia_api: custom-octavia:latest  # with driver pre-installed

conf:
  octavia:
    api_settings:
      enabled_provider_drivers: amphora:amphora,loxilb:loxilb
    loxilb:
      # Generated configuration here
```

### 🎯 DevStack Development
```bash
# Install directly
pip install octavia-loxilb-driver
octavia-loxilb-setup --deployment-type devstack

# Or add to local.conf for automated setup

# Generate configuration only
pip install octavia-loxilb-driver
octavia-loxilb-setup --output-config /tmp/loxilb-config.conf

# Review and manually integrate configuration
# Restart services based on your deployment method
```

## 🔍 Verification

### Check Provider Availability
