Overview Node-RED is a flow based, low-code development tool for event-driven applications, built on Node.js. It provides a browser based editor that makes it easy to wire together flows using the wide range of nodes in its palette, connecting hardware devices, APIs and online services in new and interesting ways. This image delivers Node-RED fully installed and configured as a system service, so a production grade flow editor is running within minutes of launch.
Application Stack Node-RED installed globally on Node.js 22 LTS and run by a dedicated unprivileged service account. The Node-RED user directory, holding your flows, the encrypted credentials store and installed nodes, stored on a dedicated data disk so it is independently resizable and survives instance replacement. A systemd service that starts Node-RED on boot and restarts it on failure. An nginx reverse proxy that publishes the flow editor on port 80 with WebSocket support for the live editor.
Flow Based Programming Drag nodes from the palette onto the canvas and wire them together to build flows that react to events, transform messages and call out to services. Node-RED ships with a rich set of core nodes for HTTP, MQTT, TCP, WebSocket, file, function and dashboard work, and the built in palette manager lets you install thousands of community nodes from the public catalogue. Flows are stored as JSON and can be exported, imported and version controlled.
Secure First Boot On the first boot of your instance a one shot service generates a fresh admin password, unique to that instance, bcrypt hashes it into the Node-RED adminAuth configuration and writes the password to a root only file. Node-RED itself binds to loopback only and is never exposed without authentication. No shared or default credentials ship in the image.
Ready To Use The flow editor is served on port 80 through nginx. Sign in with the generated administrator credentials to build flows, install nodes, manage the runtime and deploy changes live. The admin HTTP API is available behind the same login for automation.

Amazon Machine Image (AMI)
An AMI is a virtual image that provides the information required to launch an instance. Amazon EC2 (Elastic Compute Cloud) instances are virtual servers on which you can run your applications and workloads, offering varying combinations of CPU, memory, storage, and networking resources. You can launch as many instances from as many different AMIs as you need.
Version release notes
Initial release of Node-RED 5.0.0 flow based low-code programming tool.
Additional details
Usage instructions
Connect via SSH on port 22 as the default login user for your operating system variant (the user guide lists it per variant). The Node-RED flow editor is served on port 80: browse to http://<instance-public-ip>/ and sign in with user admin and the generated password. Retrieve the credentials with: sudo cat /root/node-red-credentials.txt. The Node-RED admin HTTP API is served on the same port 80 behind the same login; obtain a bearer token by POSTing client_id=node-red-admin, grant_type=password, scope=*, username=admin and your password to http://<instance-public-ip>/auth/token. The Node-RED user directory, holding flows.json, the encrypted credentials store and installed nodes, lives on a dedicated data disk mounted at /var/lib/node-red.
