This guide is a practical runbook for deploying NodeTool end-to-end with the unified server entrypoint (nodetool serve).

It covers two production scenarios:

  1. Local / desktop runtime (no remote auth)
  2. Supabase-backed server (multi-user auth)

What Runs in Production

The server entrypoint is:

nodetool serve --host 0.0.0.0 --port 7777

nodetool serve accepts only --host (default 127.0.0.1) and --port (default 7777). It sets HOST and PORT and starts the server from the built @nodetool-ai/websocket package. Use environment variables to control auth and runtime behavior. Run node backend/server.mjs in the Docker image, where HOST defaults to 0.0.0.0 in production mode.

Important runtime behavior:

  • Auth is enabled automatically when both SUPABASE_URL and SUPABASE_KEY are set; otherwise the server uses a local auth provider. There is no AUTH_PROVIDER switch read by serve.
  • Production mode is selected by NODETOOL_ENV=production (the container also sets NODE_ENV=production). Production mode also turns off the /mcp mount and the Python bridge until you opt in, see Self-Hosted Deployment.
  • The server needs a secrets master key. It reads SECRETS_MASTER_KEY first, then the system keychain, and generates a key into the keychain when neither exists. A host with no keychain (a headless Linux server) must set SECRETS_MASTER_KEY. The Docker image generates one into /workspace/.secrets_master_key when you leave it unset.
  • /health (503 when the database check fails or the server is draining), /ready (liveness), and /api/health (version and uptime) require no authentication.

Prerequisites

  • NodeTool CLI installed (@nodetool-ai/cli).
  • Container runtime:
    • Docker or
    • Podman
  • Image for local deployment tests. The image refuses to start unless DB_PATH or DATABASE_URL is set. Build it from the repository root:
docker build -t nodetool:local .

If you use Podman:

podman build -t nodetool:local .

1) Local / Desktop Runtime (no remote auth)

Use this for local runtime where the app talks to a local API server. With no SUPABASE_* vars set, the server uses the local auth provider.

export DB_PATH=/path/to/workspace/nodetool.db
export HF_HOME=/path/to/hf-cache
nodetool serve --host 127.0.0.1 --port 7777

Verify:

curl -s http://127.0.0.1:7777/health
curl -s http://127.0.0.1:7777/ready

2) Supabase-Backed Server

Use this for internet-facing deployments where user auth is Supabase-backed. Setting both SUPABASE_URL and SUPABASE_KEY enables and enforces Supabase auth.

export NODETOOL_ENV=production
export SUPABASE_URL=https://<project>.supabase.co
export SUPABASE_KEY=<service-role-or-server-key>
export SECRETS_MASTER_KEY=<strong-random-secret>
export DB_PATH=/workspace/nodetool.db
export HF_HOME=/hf-cache
nodetool serve --host 0.0.0.0 --port 7777

Verify:

curl -i http://<host>:7777/health
curl -i http://<host>:7777/api/workflows

Expected:

  • /health returns 200 (no auth required).
  • /api/workflows without auth returns 401/403.

Containerized End-to-End Run

Docker

docker run --rm -p 7777:7777 \
  -e NODETOOL_ENV=production \
  -e SECRETS_MASTER_KEY=<secret> \
  -e DB_PATH=/workspace/nodetool.db \
  -e HF_HOME=/hf-cache \
  -v $(pwd)/workspace:/workspace \
  -v $(pwd)/hf-cache:/hf-cache \
  nodetool:local

To enable Supabase auth, add -e SUPABASE_URL=… -e SUPABASE_KEY=… and -e SUPABASE_ANON_KEY=… for the login screen. Without Supabase, the server runs in Local mode and rejects requests that do not come from loopback or a network in NODETOOL_TRUST_LOCAL_NETWORKS, which docker run does not set. See Authentication.

Podman

podman run --rm -p 7777:7777 \
  -e NODETOOL_ENV=production \
  -e SECRETS_MASTER_KEY=<secret> \
  -e DB_PATH=/workspace/nodetool.db \
  -e HF_HOME=/hf-cache \
  -v $(pwd)/workspace:/workspace \
  -v $(pwd)/hf-cache:/hf-cache \
  nodetool:local

Workflow Sync to a Deployed Server

Create the deployment config with nodetool deploy init and nodetool deploy add <name> --type docker (the file is deployment.yaml in the NodeTool config directory, ~/.config/nodetool/ on Linux). The deployment’s host and container.port give the server URL. Pass an admin bearer token with --token or NODETOOL_ADMIN_TOKEN, then sync:

export NODETOOL_ADMIN_TOKEN=<admin token>
nodetool deploy workflows sync <deployment-name> <workflow-id>

Sync pushes the workflow definition only. Assets and models are not copied.

List remote workflows:

nodetool deploy workflows list <deployment-name>

Run synced workflow via REST:

curl -s -X POST http://<host>:7777/api/workflows/<workflow-id>/run \
  -H "Authorization: Bearer <token>" \
  -H "Content-Type: application/json" \
  -d '{}'

Production Checklist

  • NODETOOL_ENV=production
  • SECRETS_MASTER_KEY set, or a persistent /workspace volume so the image can keep its generated key
  • Supabase auth (SUPABASE_URL + SUPABASE_KEY) configured if you need remote auth
  • /health and /ready are green
  • Unauthorized access to protected endpoints returns 401/403
  • Workflow sync and workflow run both succeed

Troubleshooting

Server exits on startup

The Docker image exits at once when neither DB_PATH nor DATABASE_URL is set. Outside the image, a host with no keychain exits when SECRETS_MASTER_KEY is missing. Generate a key:

openssl rand -base64 32

docker run or podman run reports “image not found”

Docker and Podman keep separate image stores. Check the one you run with:

docker image ls | grep nodetool
podman image ls | grep nodetool

Then rebuild/tag in that same runtime context.
