node-red-private-catalogue-builder

A minimal web app to host a catalogue.json file for a private repository of Node-RED nodes.

Intended to be run in it's own container as part of either multi-tenant-node-red or multi-tenant-node-red-k8s

Configure

The container takes the following Environment variables:

  • PORT - Which port to listen on (defaults to 3000)
  • HOST - Which local IP Address to bind to (defaults to 0.0.0.0)
  • REGISTRY - A host and optional port number to connect to the NPM registry (defaults to https://registry:4873)
  • KEYWORD - The npm keyword to filter on (defaults to node-red)

It presents 2 HTTP endpoints

  • /update - a POST to this endpoint will trigger a rebuild of the catalogue
  • /catalogue.json - a GET request returns the current catalogue

The /update endpoint is intended to be used with the verdaccio private registry configured to send notifications when packages are uploaded/updated. e.g.

notify:
  method: POST
  headers: [{'Content-Type': 'application/json'}]
  endpoint: https://catalogue/update
  content: '{"name": "{{name}}", "versions": "{{versions}}", "dist-tags": "{{dist-tags}}"}'

Build

Build and push the container to the private container repository.

$ docker build . -t catalogue
$ docker tag catalogue private.example.com/catalogue
$ docker push private.example.com/catalogue
