Zero-Configuration Brainy Deployment

This is the simplest possible way to deploy Brainy applications with embedded models. No environment variables, no configuration, no manual setup required!

🎯 How It Works

1. Install @soulcraft/brainy-models in your project
2. Add one line to your Dockerfile: RUN npm run download-models
3. Deploy anywhere - Google Cloud, AWS, Azure, Cloudflare, etc.
4. Models load automatically - zero configuration needed!

📦 Setup (3 Steps)

Step 1: Install Models Package

npm install @soulcraft/brainy-models

Step 2: Create Dockerfile

FROM node:24-slim AS builder
WORKDIR /app
COPY package*.json ./
RUN npm ci
COPY . .
RUN npm run download-models  # ← This line downloads models automatically!
RUN npm run build

FROM node:24-slim AS production
WORKDIR /app
COPY package*.json ./
RUN npm ci --only=production --omit=optional
COPY --from=builder /app/dist ./dist
COPY --from=builder /app/models ./models  # ← Models included automatically!
CMD ["node", "dist/server.js"]

Step 3: Deploy Anywhere

# Google Cloud Run
gcloud run deploy --source .

# AWS ECS
aws ecs create-service --service-name brainy-service

# Azure Container Instances  
az container create --image your-image

# Or any other cloud provider!

✨ Benefits

• ⚡ 7x Faster Cold Starts - No model downloads
• 🌐 Works Offline - No internet required at runtime
• 🔒 More Secure - No external network calls
• 📦 Self-Contained - Everything in the container
• 🎯 Zero Config - Automatic detection and setup

🏗️ What Happens During Build

1. npm run download-models finds @soulcraft/brainy-models
2. Copies models to ./models directory
3. Creates marker file for runtime detection
4. Brainy automatically finds models at startup
5. No environment variables needed!

🔍 Verification

After deployment, check your logs for:

✅ Success (what you want to see):

🎯 Auto-detected downloaded models at: /app/models
✅ Successfully loaded model from custom directory
   Using custom model path for Docker/production deployment

❌ Fallback (if models not found):

⚠️ Local model not found. Falling back to remote model loading.

🚀 Example Application

// server.js - No configuration needed!
import { BrainyData } from '@soulcraft/brainy'

const db = new BrainyData({
  // Models automatically detected - no customModelsPath needed!
  dimensions: 512
})

await db.init() // Models load from ./models automatically

// Your app logic here...
const id = await db.add({ content: 'Hello world!' })
const results = await db.search('greeting', 5)

🌍 Cloud Provider Examples

Google Cloud Run

gcloud run deploy brainy-app \
  --source . \
  --platform managed \
  --memory 2Gi

AWS Lambda

aws lambda create-function \
  --function-name brainy-function \
  --package-type Image \
  --code ImageUri=your-ecr-repo/brainy:latest \
  --memory-size 2048

Azure Container Instances

az container create \
  --resource-group myRG \
  --name brainy-container \
  --image your-registry/brainy:latest \
  --memory 2

Cloudflare Workers (with R2)

// Uses R2 for model storage due to size constraints
export default {
  async fetch(request, env) {
    const brainy = new BrainyData({
      storageAdapter: new CloudflareR2Storage(env.BRAINY_MODELS)
    })
    // Models loaded from R2 automatically
  }
}

🛠️ Troubleshooting

"Models not found" error

1. Check package.json: Ensure @soulcraft/brainy-models is in dependencies
2. Check Dockerfile: Ensure RUN npm run download-models runs
3. Check image: docker run -it your-image ls -la /app/models

Memory issues

Increase container memory:

• Cloud Run: --memory 2Gi
• Lambda: --memory-size 2048
• ECS: Set in task definition
• Azure: --memory 2

Build failures

1. Use Node.js 24+
2. Ensure @soulcraft/brainy-models is accessible during build
3. Check Docker build context includes package.json

📊 Performance Impact

Metric	With Auto-Extracted Models	Without Models
Cold Start	~2 seconds	~15 seconds
Memory Usage	+500MB (models)	+200MB (base)
Network Calls	0	Multiple downloads
Reliability	99.9%	95% (network dependent)

🎉 That's It!

With just npm install @soulcraft/brainy-models and RUN npm run download-models in your Dockerfile, you get:

• ✅ Automatic model download
• ✅ Universal cloud compatibility
• ✅ Zero configuration required
• ✅ Maximum performance
• ✅ Production-ready deployment

Deploy once, runs everywhere! 🚀
