Lab Setup: Ollama, vLLM & Docker Compose
Complete lab setup guide for AI red teaming: local model serving with Ollama and vLLM, GPU configuration, Docker Compose for multi-service testing environments.
Lab Setup: Ollama, vLLM & Docker Compose
A reliable, reproducible lab environment is the foundation of professional AI red teaming. This guide walks through setting up local model serving, GPU configuration, and multi-service orchestration so you can test against realistic targets without depending on external APIs.
Why Local Labs
| Concern | Cloud API | Local Lab |
|---|---|---|
| Cost | Per-token billing adds up fast | One-time hardware investment |
| Rate limits | Throttled during intensive testing | Unlimited local throughput |
| Privacy | Attack payloads sent to third party | Everything stays on your machine |
| Reproducibility | Model versions change without notice | Pin exact model versions |
| Availability | Downtime, deprecations | Always available |
Hardware Requirements
| Component | Minimum | Recommended | Notes |
|---|---|---|---|
| GPU | 8GB VRAM (RTX 3070) | 24GB+ VRAM (RTX 4090 / A100) | More VRAM = larger models |
| RAM | 16GB | 64GB+ | CPU offloading needs system RAM |
| Storage | 100GB SSD | 500GB+ NVMe | Models are 4-70GB each |
| CPU | 8 cores | 16+ cores | Tokenization, orchestration |
Ollama: Quick Start Model Serving
Ollama is the fastest path to local model serving. It handles model downloads, quantization, and serving behind a simple API.
Install Ollama
curl -fsSL https://ollama.ai/install.sh | sh # Verify installation ollama --versionPull Models for Testing
# Small model for fast iteration ollama pull llama3.2:3b # Medium model for realistic testing ollama pull llama3.1:8b # Large model for production-grade simulation ollama pull llama3.1:70b-q4_K_M # Pull a model with safety training for guardrail testing ollama pull llama-guard3:8bCreate Custom Modelfiles

curl http://localhost:11434/api/chat -d '{ "model": "acme-assistant", "messages": [{"role": "user", "content": "Hello, I need help with my account"}], "stream": false }'
vLLM: Production-Grade Serving
vLLM provides production-grade serving with OpenAI-compatible APIs, making it ideal for testing against realistic deployment configurations.
Install vLLM
pip install vllmStart the Server
python -m vllm.entrypoints.openai.api_server \ --model meta-llama/Llama-3.1-8B-Instruct \ --host 0.0.0.0 \ --port 8000 \ --max-model-len 4096 \ --gpu-memory-utilization 0.9 \ --enforce-eagerQuery with OpenAI SDK
from openai import OpenAI client = OpenAI( base_url="http://localhost:8000/v1", api_key="not-needed" ) response = client.chat.completions.create( model="meta-llama/Llama-3.1-8B-Instruct", messages=[ {"role": "system", "content": "You are a helpful assistant."}, {"role": "user", "content": "Hello!"} ] ) print(response.choices[0].message.content)
GPU Configuration for Docker
# Install NVIDIA Container Toolkit

Version Pinning Checklist
| Component | How to Pin |
|---|---|
| Model weights | Record exact HuggingFace revision hash or Ollama model digest |
| vLLM version | Pin in requirements.txt or Docker image tag |
| System prompt | Version-control all Modelfiles and prompt configs |
| Docker images | Use SHA256 digests, not latest tags |
| Python dependencies | pip freeze > requirements.txt |
| CUDA / drivers | Document nvidia-smi output |
