Deployment

Perstack runs on any Node.js environment. Choose your deployment target based on security requirements, cost, and operational preferences.

Docker

Build a container image for your Expert:

FROM node:22-slim
WORKDIR /app
COPY perstack.toml /app/perstack.toml
RUN npm install -g perstack
ENTRYPOINT ["perstack", "run", "--config", "/app/perstack.toml"]

Run with isolation controls:

docker build -t my-expert .
docker run --rm \
  -e ANTHROPIC_API_KEY \
  -v $(pwd)/workspace:/workspace \
  my-expert my-expert "query"

For production, add resource limits and network restrictions. See Isolation by Design.

Cloudflare Workers

import { run } from "@perstack/runtime"

export default {
  async fetch(request: Request, env: Env) {
    const { query, expertKey } = await request.json()
    const events: unknown[] = []
    await run(
      { expertKey, query, providerConfig: { apiKey: env.ANTHROPIC_API_KEY } },
      { eventListener: (event) => events.push(event) }
    )
    return Response.json(events)
  }
}

Secrets management

Never hardcode API keys. Use platform-native secrets:

Platform	Method
Docker	Environment variables, Docker secrets
AWS	Secrets Manager, Parameter Store
GCP	Secret Manager
Cloudflare	Workers secrets (`wrangler secret put`)

Registry Experts

Deploy Experts from the registry without building custom images:

docker run --rm \
  -e ANTHROPIC_API_KEY \
  -v $(pwd)/workspace:/workspace \
  node:22-slim \
  npx perstack run @org/expert@1.0.0 "query"

Pin versions for reproducible deployments.
