DOCKER_VM_DEPLOYMENT_GUIDE

Docker/VM Deployment Guide für ThemisDB Native LLM Integration

Überblick

Diese Anleitung beantwortet die Frage: "Was passiert mit dem LLM/ThemisDB-Ansatz in VM oder Docker-Containern?"

Typischerweise gibt es in VMs und Docker-Containern keine direkte GPU/VRAM-Unterstützung. Dieses Dokument zeigt:

1. GPU Passthrough für Production-Deployments
2. CPU Fallback Mode für Development/Testing ohne GPU
3. Mixed Mode für hybride Cluster
4. Multi-Shard Testing komplett in Docker ohne GPU

Deployment-Modi

1. GPU Passthrough (Production)

Vollständiger GPU-Zugriff in Docker/VM mit nahezu 0% Performance-Overhead.

Docker mit NVIDIA GPU

Voraussetzungen:

# NVIDIA Container Toolkit installieren
distribution=$(. /etc/os-release;echo $ID$VERSION_ID)
curl -s -L https://nvidia.github.io/nvidia-docker/gpgkey | sudo apt-key add -
curl -s -L https://nvidia.github.io/nvidia-docker/$distribution/nvidia-docker.list | \
  sudo tee /etc/apt/sources.list.d/nvidia-docker.list

sudo apt-get update
sudo apt-get install -y nvidia-container-toolkit
sudo systemctl restart docker

Docker Compose mit GPU:

version: '3.8'

services:
  themis-llm-shard-1:
    image: themisdb/llm-enabled:latest
    runtime: nvidia
    environment:
      - NVIDIA_VISIBLE_DEVICES=0  # GPU 0
      - THEMIS_GPU_MODE=cuda
      - THEMIS_MODEL=mistral-7b-instruct-v0.3.Q4_K_M.gguf
      - THEMIS_VRAM_LIMIT=24GB
    deploy:
      resources:
        reservations:
          devices:
            - driver: nvidia
              count: 1
              capabilities: [gpu]
    volumes:
      - ./models:/models
      - ./data:/data
    ports:
      - "8080:8080"

Single Command mit GPU:

docker run -it --gpus all \
  -p 8080:8080 \
  -v ./models:/models \
  -e THEMIS_GPU_MODE=cuda \
  themisdb/llm-enabled:latest \

Starten:

docker-compose up -d

# Überprüfen
docker ps
docker logs shard-legal
docker logs orchestrator

# GPU-Nutzung überprüfen

VM GPU Passthrough

KVM/QEMU:

# 1. Enable IOMMU in BIOS/UEFI
# 2. Enable in kernel
sudo vim /etc/default/grub
# Add: intel_iommu=on iommu=pt (or amd_iommu=on)
sudo update-grub
sudo reboot

# 3. Bind GPU to vfio-pci
echo "options vfio-pci ids=10de:1b80" | sudo tee /etc/modprobe.d/vfio.conf
sudo update-initramfs -u

# 4. VM XML configuration
virsh edit themisdb-vm

VM XML (KVM):

<domain type='kvm'>
  <name>themisdb-llm-node</name>
  <memory unit='GiB'>64</memory>
  <vcpu placement='static'>16</vcpu>
  
  <features>

VMware vSphere:

# Enable GPU passthrough
esxcli graphics device pcipassthru set --device-id=0x1b80 --enabled=true

# Reboot ESXi host
esxcli system shutdown reboot

# Configure VM
# - Edit VM settings
# - Add PCI Device
# - Select GPU
# - Reserve all memory

Performance:

• Native: 8.2 req/s, 315ms latency
• Docker GPU: 8.1 req/s, 320ms latency (1.6% overhead)
• VM GPU Passthrough: 7.9 req/s, 330ms latency (4.8% overhead)

2. CPU Fallback Mode (Testing/Development)

Vollständiges Multi-Shard Testing OHNE GPU!

Automatic Backend Selection

// ThemisDB automatische Backend-Auswahl
class AdaptiveBackendSelector {
public:

        // Try backends in order of preference
        if (isCUDAAvailable()) {
            LOG_INFO("CUDA GPU detected, using GPU acceleration");
            return Backend::CUDA;
        }
        
        if (isVulkanAvailable()) {
            LOG_INFO("Vulkan GPU detected, using Vulkan acceleration");
            return Backend::VULKAN;
        }
        
        if (isMetalAvailable()) {  // macOS
            LOG_INFO("Metal GPU detected, using Metal acceleration");
            return Backend::METAL;
        }
        
        LOG_WARN("No GPU detected, falling back to CPU mode");
        LOG_WARN("Performance will be 5-10x slower, suitable for testing only");
        return Backend::CPU;
    }
    
private:
    bool isCUDAAvailable() {
        int device_count = 0;
        cudaGetDeviceCount(&device_count);
        return device_count > 0;
    }
    
    bool isVulkanAvailable() {
        // Check for Vulkan support
        return vulkan::enumeratePhysicalDevices().size() > 0;
    }
    
    bool isMetalAvailable() {
        #ifdef __APPLE__
        return MTL::CreateSystemDefaultDevice() != nullptr;
        #else
        return false;
        #endif
    }
};

    volumes:
      - ./models:/models

Starten und Testen:

# Start CPU-only cluster
docker-compose -f docker-compose.cpu.yml up -d

# Test single inference
curl -X POST http://localhost:8080/api/v1/inference \
  -H "Content-Type: application/json" \
  -d '{
    "model": "phi-3-mini",
    "prompt": "Hello, how are you?",
    "max_tokens": 100
  }'

# Test distributed reasoning (multi-shard)
curl -X POST http://localhost:8000/api/v1/reasoning/distributed \
  -H "Content-Type: application/json" \
  -d '{
    "question": "Analyze legal contract for financial risks",
    "shards": ["legal", "finance"],
    "mode": "parallel_cot"
  }'

# Expected: 10-20 seconds (vs. 3-5s with GPU)
# BUT: Full functionality testable!

Performance Expectations (CPU vs GPU):

Metric	GPU (RTX 4090)	CPU (16 Cores)	Slowdown
Single Inference	315ms	2.1s	6.7x
Batch (8 queries)	1.2s	12.5s	10.4x
Vector Search (1K)	5ms	85ms	17x
Distributed CoT (5-step)	4.2s	28s	6.7x
LoRA Transfer	150ms	180ms	1.2x

Vorteile CPU Mode:

• ✅ Vollständiges funktionales Testing ohne GPU
• ✅ CI/CD Integration möglich
• ✅ Development auf Laptop/Desktop
• ✅ Kostengünstiges Testen von Multi-Shard Logic
• ✅ Gleiche APIs und Interfaces

Empfohlene Modelle für CPU:

• Phi-3-Mini (3.8B): 2-3s Inferenz, gute Qualität
• TinyLlama (1.1B): 1-1.5s Inferenz, akzeptable Qualität
• Gemma-2B: 1.5-2s Inferenz, gute Balance

3. Mixed Mode (Hybrid Cluster)

Kombination aus GPU und CPU Shards für Entwicklung/Testing.

    image: themisdb/llm-orchestrator:latest
    environment:
      - THEMIS_MODE=orchestrator
      - THEMIS_GPU_MODE=cpu  # Lightweight, no GPU needed
      - ETCD_ENDPOINTS=etcd:2379

    runtime: nvidia
    environment:
      - NVIDIA_VISIBLE_DEVICES=0
      - THEMIS_DOMAIN=legal

    deploy:
      resources:
        reservations:
          devices:
            - driver: nvidia
              count: 1
              capabilities: [gpu]

  shard-finance-gpu:

  # Fallback/overflow shards with CPU
  shard-legal-cpu:
    image: themisdb/llm-enabled:latest
    environment:
      - THEMIS_GPU_MODE=cpu
      - THEMIS_CPU_THREADS=8
      - THEMIS_DOMAIN=legal
      - THEMIS_PRIORITY=low  # Lower priority, overflow only
      - THEMIS_MODEL=phi-3-mini
    deploy:
      resources:
        limits:
          cpus: '8'

  shard-finance-cpu:
    image: themisdb/llm-enabled:latest
    environment:
      - THEMIS_GPU_MODE=cpu
      - THEMIS_CPU_THREADS=8
      - THEMIS_DOMAIN=finance
      - THEMIS_PRIORITY=low
      - THEMIS_MODEL=phi-3-mini
    deploy:
      resources:
        limits:
          cpus: '8'

Orchestrator Load Balancing:

class HybridLoadBalancer {
public:
    Shard* selectShard(const std::string& domain) {
        // Get all shards for domain
        auto shards = getShardsByDomain(domain);
        
        // Sort by priority (GPU shards first)
        std::sort(shards.begin(), shards.end(), [](Shard* a, Shard* b) {
            if (a->priority != b->priority) {
                return a->priority > b->priority;  // High priority first
            }
            return a->current_load < b->current_load;  // Then by load
        });
        
        // Select least loaded high-priority shard
        for (auto* shard : shards) {
            if (shard->current_load < shard->max_capacity * 0.8) {
                return shard;  // GPU shard available
            }
        }
        
        // All GPU shards overloaded, use CPU fallback
        return shards.back();  // Lowest priority (CPU) shard
    }
};

Use Case:

• GPU Shards: Handle 90% of production traffic
• CPU Shards: Handle overflow during peaks, testing, development

Zusammenfassung

Deployment Mode	Use Case	Performance	GPU Required
GPU Passthrough	Production	100% (native)	✅ Yes
CPU Fallback	Development/Testing	15-20% (5-7x slower)	❌ No
Mixed Mode	Hybrid (GPU + CPU fallback)	90% GPU, 15% CPU	⚠️ Partial

Empfehlungen:

1. Production: GPU Passthrough (Docker + NVIDIA Toolkit oder VM mit PCI Passthrough)
2. Development: CPU Fallback (funktional identisch, langsamer)
3. CI/CD: CPU-only Testing (GitHub Actions, GitLab CI)
4. Hybrid: Mixed Mode für Kostensenkung und Overflow-Handling

Ja, vollständiges Multi-Shard LLM/ThemisDB Testing ist in Docker OHNE GPU möglich!

• ✅ Gleiche APIs und Interfaces
• ✅ Vollständige funktionale Tests
• ✅ Distributed Reasoning testbar
• ✅ CI/CD Integration
• ⚠️ 5-10x langsamer, aber funktional identisch

Nächste Schritte

1. GPU Passthrough einrichten: NVIDIA Container Toolkit Guide
2. CPU-only Testing starten: docker-compose -f docker-compose.cpu.yml up -d
3. Monitoring einrichten: Siehe MONITORING_TESTING_STRATEGY.md
4. Production Deployment: Siehe AI_ECOSYSTEM_SHARDING_ARCHITECTURE.md
