Node-RED on Ubuntu 24.04 LTS by cloudimg

## Node-RED on Ubuntu 24.04 LTS by cloudimg

Node-RED is the low-code, flow-based development tool for event-driven applications. Its browser-based editor lets you wire together hardware devices, APIs and online services from a rich palette of nodes, then deploy flows to its lightweight Node.js runtime in a single click. It is the de facto standard for IoT integration, API orchestration, home and industrial automation, and rapid prototyping of event-driven logic. The cloudimg image installs Node-RED 5.0.0 on Node.js 22 LTS, runs it as a dedicated systemd service bound to loopback behind an nginx reverse proxy on port 80 with HTTP Basic auth, persists all flows and settings on a dedicated Azure data disk, and generates a unique editor password on the first boot of every VM. Backed by 24/7 expert support.

Dedicated Data Disk

The Node-RED user directory (flows, settings, credentials and installed palette nodes) lives on a dedicated, independently resizable Azure data disk mounted at /var/lib/node-red, separate from the OS disk and re-provisioned with every VM. Snapshot it to back up your flows.

Secure By Default

The flow editor controls a runtime that can execute code, so it is bound to loopback and nginx fronts it on port 80 with HTTP Basic auth. The per-VM admin password is unique to each VM, generated on first boot and stored in a root-only file. Front the proxy with TLS for production.
