# Docker Deployment Guide
**Status:** In Development for v0.2.0
**Requested By:** Reddit community ([thread](https://reddit.com/r/LocalLLaMA/...))
## Overview
Docker support makes Voicebox easier to deploy, especially for:
- **Consistent Environments**: Same setup across dev/staging/prod
- **GPU Passthrough**: Easy NVIDIA/AMD GPU access
- **Server Deployments**: Run on headless Linux servers
- **Multi-User Setups**: Isolate instances per user/team
- **Cloud Platforms**: Deploy to AWS, GCP, Azure, DigitalOcean
## Quick Start
### Using Pre-Built Images (Recommended)
```bash
# CPU-only version
docker run -p 8000:8000 -v voicebox-data:/app/data \
ghcr.io/jamiepine/voicebox:latest
# NVIDIA GPU version
docker run --gpus all -p 8000:8000 -v voicebox-data:/app/data \
ghcr.io/jamiepine/voicebox:latest-cuda
# AMD GPU version (experimental)
docker run --device=/dev/kfd --device=/dev/dri -p 8000:8000 \
-v voicebox-data:/app/data \
ghcr.io/jamiepine/voicebox:latest-rocm
```
Then open: `http://localhost:8000`
### Using Docker Compose (Easiest)
Create `docker-compose.yml`:
```yaml
version: '3.8'
services:
voicebox:
image: ghcr.io/jamiepine/voicebox:latest-cuda
ports:
- "8000:8000"
volumes:
- voicebox-data:/app/data
- huggingface-cache:/root/.cache/huggingface
environment:
- GPU_MEMORY_FRACTION=0.8 # Use 80% of GPU memory
- TTS_MODE=local
- WHISPER_MODE=local
deploy:
resources:
reservations:
devices:
- driver: nvidia
count: 1
capabilities: [gpu]
volumes:
voicebox-data:
huggingface-cache:
```
Run:
```bash
docker compose up -d
```
## Building From Source
### Basic Dockerfile
```dockerfile
# Dockerfile
FROM python:3.11-slim
WORKDIR /app
# Install system dependencies
RUN apt-get update && apt-get install -y \
git \
build-essential \
ffmpeg \
&& rm -rf /var/lib/apt/lists/*
# Copy application
COPY backend/ /app/backend/
COPY requirements.txt /app/
# Install Python dependencies
RUN pip install --no-cache-dir -r requirements.txt
RUN pip install --no-cache-dir git+https://github.com/QwenLM/Qwen3-TTS.git
# Create data directory
RUN mkdir -p /app/data
# Expose port
EXPOSE 8000
# Run server
CMD ["uvicorn", "backend.main:app", "--host", "0.0.0.0", "--port", "8000"]
```
Build and run:
```bash
docker build -t voicebox .
docker run -p 8000:8000 -v $(pwd)/data:/app/data voicebox
```
### Multi-Stage Build (Optimized)
Smaller image size by separating build and runtime:
```dockerfile
# Dockerfile.optimized
# Stage 1: Build dependencies
FROM python:3.11-slim AS builder
WORKDIR /build
RUN apt-get update && apt-get install -y \
git build-essential && \
rm -rf /var/lib/apt/lists/*
COPY backend/requirements.txt .
RUN pip install --no-cache-dir --target=/build/packages \
-r requirements.txt
RUN pip install --no-cache-dir --target=/build/packages \
git+https://github.com/QwenLM/Qwen3-TTS.git
# Stage 2: Runtime
FROM python:3.11-slim
WORKDIR /app
# Install only runtime dependencies
RUN apt-get update && apt-get install -y \
ffmpeg \
&& rm -rf /var/lib/apt/lists/*
# Copy installed packages from builder
COPY --from=builder /build/packages /usr/local/lib/python3.11/site-packages/
# Copy application code
COPY backend/ /app/backend/
# Create data directory
RUN mkdir -p /app/data
EXPOSE 8000
CMD ["uvicorn", "backend.main:app", "--host", "0.0.0.0", "--port", "8000"]
```
Build:
```bash
docker build -f Dockerfile.optimized -t voicebox:slim .
```
## GPU Support
### NVIDIA GPUs (CUDA)

```
**Run with GPU:**
```bash
docker run --gpus all -p 8000:8000 \
-v voicebox-data:/app/data \
voicebox:cuda
```
**Docker Compose with GPU:**
```yaml
services:
voicebox:
image: voicebox:cuda
deploy:
resources:
reservations:
devices:
- driver: nvidia
count: all
capabilities: [gpu]
```
### AMD GPUs (ROCm) - Experimental
**Dockerfile:**
```dockerfile
FROM rocm/dev-ubuntu-22.04:6.0
# Install Python
RUN apt-get update && apt-get install -y \
python3.11 python3-pip git ffmpeg && \
rm -rf /var/lib/apt/lists/*
WORKDIR /app
# Install PyTorch with ROCm support
COPY backend/requirements.txt .
RUN pip3 install torch torchvision torchaudio --index-url https://download.pytorch.org/whl/rocm6.0
# Install other dependencies
RUN pip3 install -r requirements.txt
RUN pip3 install git+https://github.com/QwenLM/Qwen3-TTS.git
# Set ROCm environment variables
ENV HSA_OVERRIDE_GFX_VERSION=10.3.0
ENV ROCM_PATH=/opt/rocm
COPY backend/ /app/backend/
EXPOSE 8000
CMD ["uvicorn", "backend.main:app", "--host", "0.0.0.0", "--port", "8000"]
```
**Run with AMD GPU:**

## Cloud Deployment
### AWS EC2
1. **Launch GPU Instance** (g4dn.xlarge or p3.2xlarge)
2. **Install Docker + nvidia-docker:**
```bash
# Amazon Linux 2
sudo yum install -y docker
sudo systemctl start docker
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-docker2
sudo systemctl restart docker
```
3. **Deploy:**
```bash
docker run --gpus all -d -p 80:8000 \
-v voicebox-data:/app/data \
--restart unless-stopped \
ghcr.io/jamiepine/voicebox:latest-cuda
```
### DigitalOcean
Use GPU Droplet + Docker:
```bash
# Create droplet via CLI
doctl compute droplet create voicebox \
--size gpu-h100x1-80gb \
--image ubuntu-22-04-x64 \
--region nyc3
# SSH and deploy
ssh root@<droplet-ip>
curl -fsSL https://get.docker.com -o get-docker.sh
sh get-docker.sh
docker run --gpus all -d -p 80:8000 voicebox:cuda
```
### Google Cloud Run (CPU-only)
```bash
# Build and push
docker build -t gcr.io/your-project/voicebox .
docker push gcr.io/your-project/voicebox
# Deploy to Cloud Run
gcloud run deploy voicebox \
--image gcr.io/your-project/voicebox \
--platform managed \
--region us-central1 \
--memory 4Gi \
--cpu 2 \
--port 8000
```
### Fly.io
Create `fly.toml`:
```toml
app = "voicebox"
[build]
image = "ghcr.io/jamiepine/voicebox:latest"
[[services]]
http_checks = []
internal_port = 8000
protocol = "tcp"
[[services.ports]]
port = 80
handlers = ["http"]
[[services.ports]]
port = 443
handlers = ["tls", "http"]
[mounts]
source = "voicebox_data"
destination = "/app/data"
```
Deploy:
```bash
fly launch
fly deploy
```
## Troubleshooting
### GPU Not Detected
**Check NVIDIA Docker:**
```bash
docker run --rm --gpus all nvidia/cuda:12.1.0-base-ubuntu22.04 nvidia-smi
```
If this fails, reinstall nvidia-docker2.
**Check AMD ROCm:**
```bash
docker run --rm --device=/dev/kfd --device=/dev/dri rocm/dev-ubuntu-22.04:6.0 rocminfo
```
### Permission Errors
Container can't write to volumes:
```bash
# Fix permissions
docker run --user $(id -u):$(id -g) -v $(pwd)/data:/app/data voicebox
```
### Out of Memory
Reduce GPU memory usage:
```bash
docker run -e GPU_MEMORY_FRACTION=0.5 voicebox
```
Or use CPU-only:
```bash
docker run -e DEVICE=cpu voicebox
```
### Model Download Fails
Ensure HuggingFace cache is writable:
```bash
docker run -v huggingface-cache:/root/.cache/huggingface voicebox
```
Or use host cache:
```bash
docker run -v ~/.cache/huggingface:/root/.cache/huggingface voicebox
```
### Port Already in Use
Change host port:
```bash
docker run -p 8080:8000 voicebox # Use port 8080 instead
```
## Security Best Practices
### 1. Don't Run as Root
Create non-root user in Dockerfile:
```dockerfile
RUN useradd -m -u 1000 voicebox
USER voicebox
```
### 2. Use Secrets for API Keys
Don't put API keys in docker-compose.yml:
```bash
# Use Docker secrets
echo "sk-your-key" | docker secret create openai_key -
docker service create \
--secret openai_key \
-e OPENAI_API_KEY_FILE=/run/secrets/openai_key \
voicebox
```
### 3. Network Isolation
Use internal networks for multi-container setups:
```yaml
services:
voicebox:
networks:
- internal
nginx:
networks:
- internal
- external
ports:
- "80:80"
networks:
internal:
internal: true
external:
```
### 4. Resource Limits
Prevent resource exhaustion:
```yaml
services:
voicebox:
deploy:
resources:
limits:
cpus: '4'
memory: 8G
reservations:
cpus: '2'
memory: 4G
```
## Performance Tuning
### GPU Memory Management
```bash
# Use 80% of GPU (default 90%)
docker run -e GPU_MEMORY_FRACTION=0.8 voicebox
# Allow GPU memory growth (prevents OOM)
docker run -e TF_FORCE_GPU_ALLOW_GROWTH=true voicebox
```
### Model Caching
Pre-download models to volume:
```bash
# Download models first
docker run --rm -v huggingface-cache:/root/.cache/huggingface \
voicebox python -c "
from transformers import WhisperProcessor, WhisperForConditionalGeneration
WhisperProcessor.from_pretrained('openai/whisper-base')
WhisperForConditionalGeneration.from_pretrained('openai/whisper-base')
"
# Then run normally
docker run -v huggingface-cache:/root/.cache/huggingface voicebox
```
### Multi-Worker Setup
Use uvicorn workers for better throughput:
```dockerfile
CMD ["uvicorn", "backend.main:app", "--host", "0.0.0.0", "--port", "8000", "--workers", "4"]
```
## Monitoring
### Health Checks
Built-in health endpoint:
```bash
curl http://localhost:8000/health
```
Docker health check:
```yaml
healthcheck:
test: ["CMD", "curl", "-f", "http://localhost:8000/health"]
interval: 30s
timeout: 10s
retries: 3
```
### Prometheus Metrics
Add metrics exporter:
```python
# backend/main.py
from prometheus_fastapi_instrumentator import Instrumentator
Instrumentator().instrument(app).expose(app)
```
Then scrape `/metrics` with Prometheus.
### Logs
View container logs:
```bash
docker logs -f voicebox
# Or with compose
docker compose logs -f voicebox
```
## Next Steps
- [ ] Publish official images to GitHub Container Registry
- [ ] Add Kubernetes Helm charts
- [ ] Create Docker Desktop extension
- [ ] Add automated vulnerability scanning
- [ ] Support ARM64 builds for Raspberry Pi / Apple Silicon

# External Provider Support
**Status:** Planned for v0.2.0
**Discussion:** [Reddit Thread](https://reddit.com/r/LocalLLaMA/...)
## Overview
External provider support allows you to connect Voicebox to remotely-hosted TTS and Whisper services instead of running models locally. This is useful for:
- **Existing GPU Infrastructure**: You already have Qwen3-TTS running on a GPU server
- **AMD GPU Users**: Run models on your AMD hardware, use Voicebox as the UI
- **Cloud Deployments**: Host models on Modal, Replicate, RunPod, etc.
- **Team Sharing**: Multiple users share one GPU server running models
- **Mixed Deployments**: Local Whisper + remote TTS, or vice versa
## Architecture
```
┌─────────────────┐ HTTP/API ┌──────────────────┐
│ Voicebox UI │ ───────────────────────> │ Your TTS Server │
│ + Backend │ │ (Qwen3-TTS on │
│ │ <─────────────────────── │ AMD/NVIDIA GPU)│
│ - Profiles │ Audio + Metadata └──────────────────┘
│ - History │
│ - Audio Edit │ HTTP/API ┌──────────────────┐
│ - UI │ ───────────────────────> │ Whisper Service │
└─────────────────┘ │ (OpenAI API or │
│ self-hosted) │
└──────────────────┘
```
**What Voicebox Still Handles:**
- Voice profile management
- Generation history
- Audio trimming/editing
- Multi-track story editor
- UI/UX layer
**What External Providers Handle:**
- Model inference (TTS generation, transcription)
- GPU allocation
- Model loading/caching
## Configuration
### Environment Variables
```bash
# TTS Provider
TTS_MODE=remote # local | remote
TTS_REMOTE_URL=http://192.168.1.100:8000 # Your TTS server URL
TTS_API_KEY=your-api-key # Optional authentication
# Whisper Provider
WHISPER_MODE=openai-api # local | openai-api | remote
WHISPER_REMOTE_URL=http://localhost:9000 # For self-hosted Whisper
OPENAI_API_KEY=sk-... # For OpenAI Whisper API
```
### Voicebox Config UI (Planned)
Settings page will include:
- Provider selection dropdowns
- URL/API key inputs
- Connection test button
- Latency/status indicators
## Hosting External Services
### Option 1: Simple FastAPI Server (Recommended)
Create a lightweight server to expose your local Qwen3-TTS model:
```python
# tts_server.py
from fastapi import FastAPI, UploadFile, File
from qwen_tts import Qwen3TTSModel
import numpy as np
import base64
app = FastAPI()
model = Qwen3TTSModel.from_pretrained(
"Qwen/Qwen3-TTS-12Hz-1.7B-Base",
device_map="cuda" # or "cpu" for AMD ROCm: use torch+rocm
)
@app.post("/v1/generate")
async def generate(
text: str,
voice_prompt: dict,
language: str = "en",
seed: int = None
):
"""Generate speech from text using voice prompt."""
audio, sample_rate = model.generate_voice_clone(
text=text,
voice_clone_prompt=voice_prompt,
)
# Return as base64 for transport
audio_bytes = audio.tobytes()
return {
"audio": base64.b64encode(audio_bytes).decode(),
"sample_rate": sample_rate,
"dtype": str(audio.dtype)
}
@app.post("/v1/create_voice_prompt")
async def create_voice_prompt(
audio: UploadFile = File(...),
reference_text: str = ""
):
"""Create voice prompt from reference audio."""
# Save uploaded audio temporarily
audio_path = f"/tmp/{audio.filename}"
with open(audio_path, "wb") as f:
f.write(await audio.read())
# Create voice prompt
voice_prompt = model.create_voice_clone_prompt(
ref_audio=audio_path,
ref_text=reference_text,
)
return {"voice_prompt": voice_prompt}
@app.get("/health")
async def health():
return {
"status": "healthy",
"model": "Qwen3-TTS-12Hz-1.7B-Base",
"device": str(model.device)
}
if __name__ == "__main__":
import uvicorn
uvicorn.run(app, host="0.0.0.0", port=8000)
```
**Run it:**
```bash
# Install dependencies
pip install fastapi uvicorn qwen-tts torch
# For AMD GPUs, use ROCm PyTorch:
pip install torch --index-url https://download.pytorch.org/whl/rocm6.4
# Start server
python tts_server.py
```
### Option 2: vLLM (If Supported)
```bash
vllm serve Qwen/Qwen3-TTS-12Hz-1.7B-Base \
--host 0.0.0.0 \
--port 8000 \
--gpu-memory-utilization 0.9
```
### Option 3: Cloud Platforms
**Modal.com Example:**
```python
import modal
app = modal.App("qwen-tts")
image = modal.Image.debian_slim().pip_install("qwen-tts", "torch")
@app.function(gpu="A10G", image=image)
@modal.web_endpoint(method="POST")
def generate(text: str, voice_prompt: dict):
from qwen_tts import Qwen3TTSModel
model = Qwen3TTSModel.from_pretrained("Qwen/Qwen3-TTS-12Hz-1.7B-Base")
audio, sr = model.generate_voice_clone(text, voice_prompt)
return {"audio": audio.tolist(), "sample_rate": sr}
```
Deploy: `modal deploy tts_server.py`
Get URL: `https://yourapp--generate.modal.run`
## API Specification
External TTS providers must implement these endpoints:
### `POST /v1/generate`
Generate speech from text.
**Request:**
```json
{
"text": "Hello, this is a test.",
"voice_prompt": { /* voice prompt object */ },
"language": "en",
"seed": 12345
}
```
**Response:**
```json
{
"audio": "base64-encoded-audio-bytes",
"sample_rate": 24000,
"dtype": "float32"
}
```
### `POST /v1/create_voice_prompt`
Create a voice prompt from reference audio.
**Request:** (multipart/form-data)
- `audio`: Audio file upload
- `reference_text`: Transcript of the audio
**Response:**
```json
{
"voice_prompt": { /* voice prompt object */ }
}
```
### `GET /health`
Health check endpoint.
**Response:**
```json
{
"status": "healthy",
"model": "Qwen3-TTS-12Hz-1.7B-Base",
"device": "cuda:0"
}
```
## Whisper External Providers
### OpenAI Whisper API
Simply set:
```bash
WHISPER_MODE=openai-api
OPENAI_API_KEY=sk-...
```
Voicebox will use OpenAI's Whisper API automatically.
### Self-Hosted Whisper
Run your own Whisper server:
```python
# whisper_server.py
from fastapi import FastAPI, UploadFile, File
from transformers import WhisperProcessor, WhisperForConditionalGeneration
import librosa
app = FastAPI()
processor = WhisperProcessor.from_pretrained("openai/whisper-base")
model = WhisperForConditionalGeneration.from_pretrained("openai/whisper-base")
@app.post("/v1/transcribe")
async def transcribe(audio: UploadFile = File(...), language: str = None):
# Load audio
audio_path = f"/tmp/{audio.filename}"
with open(audio_path, "wb") as f:
f.write(await audio.read())
audio_data, sr = librosa.load(audio_path, sr=16000)
# Process
inputs = processor(audio_data, sampling_rate=16000, return_tensors="pt")
predicted_ids = model.generate(inputs["input_features"])
transcription = processor.batch_decode(predicted_ids, skip_special_tokens=True)[0]
return {"text": transcription}
```
Configure Voicebox:
```bash
WHISPER_MODE=remote
WHISPER_REMOTE_URL=http://localhost:9000
```
## Use Cases
### 1. AMD GPU User with Existing Setup
**Scenario:** You have a Radeon 7900 XTX running Qwen3-TTS on Linux.
**Setup:**
1. Run `tts_server.py` on your AMD box (ROCm PyTorch)
2. Configure Voicebox: `TTS_MODE=remote`, `TTS_REMOTE_URL=http://amd-box:8000`
3. Use Voicebox UI for profiles, generation, editing
4. TTS happens on your AMD GPU
### 2. Team Deployment
**Scenario:** 5 team members, 1 GPU server.
**Setup:**
1. Deploy TTS server on shared GPU box
2. Each person runs Voicebox desktop app locally
3. All point to same `TTS_REMOTE_URL`
4. Profiles and history stay local per user
5. GPU usage is shared
### 3. Hybrid Local/Remote
**Scenario:** Fast local Whisper, heavy TTS on cloud.
**Setup:**
```bash
TTS_MODE=remote
TTS_REMOTE_URL=https://your-modal-app.modal.run
WHISPER_MODE=local # Fast transcription on your CPU
```
### 4. OpenAI Whisper + Self-Hosted TTS
**Scenario:** Use OpenAI's API for transcription, run TTS locally.
**Setup:**
```bash
TTS_MODE=local
WHISPER_MODE=openai-api
OPENAI_API_KEY=sk-...
```
## Security Considerations
### Authentication
Add API key authentication to your external server:
```python
from fastapi import Header, HTTPException
API_KEY = "your-secret-key"
async def verify_api_key(x_api_key: str = Header(...)):
if x_api_key != API_KEY:
raise HTTPException(status_code=401, detail="Invalid API key")
@app.post("/v1/generate", dependencies=[Depends(verify_api_key)])
async def generate(...):
...
```
Configure Voicebox:
```bash
TTS_API_KEY=your-secret-key
```
### Network Security
- **VPN/Tailscale**: Use private network for remote servers
- **HTTPS**: Use reverse proxy (nginx/Caddy) with SSL certificates
- **Firewall**: Restrict access to known IPs
### Rate Limiting
Protect your external server:
```python
from slowapi import Limiter
from slowapi.util import get_remote_address
limiter = Limiter(key_func=get_remote_address)
app.state.limiter = limiter
@app.post("/v1/generate")
@limiter.limit("10/minute")
async def generate(...):
...
```
## Performance Considerations
### Latency
External providers add network latency:
- **Local network**: ~10-50ms overhead (negligible)
- **Same datacenter**: ~1-5ms overhead
- **Cross-region cloud**: 50-200ms+ overhead
For real-time applications, keep TTS server on local network or same cloud region.
### Caching
Implement response caching on external server:
```python
from functools import lru_cache
@lru_cache(maxsize=1000)
def get_cached_generation(text, voice_prompt_hash, language, seed):
return model.generate_voice_clone(text, voice_prompt)
```
### Load Balancing
For high-traffic deployments, run multiple TTS servers behind a load balancer:
```
Voicebox ──> Load Balancer ──> TTS Server 1 (GPU 1)
├──> TTS Server 2 (GPU 2)
└──> TTS Server 3 (GPU 3)
```
## Future Enhancements
- [ ] **Provider Marketplace**: Built-in directory of compatible providers
- [ ] **Automatic Fallback**: If remote fails, fallback to local
- [ ] **Cost Tracking**: Monitor API usage and costs
- [ ] **Performance Metrics**: Latency, throughput dashboards
- [ ] **Multi-Provider**: Use different providers for different voices/languages
