Adding "node-red-contrib-home-assistant-websocket" automatically in node-red docker

Third party integrations Node-RED
1

This is how I install node-red

  node-red:
    image: nodered/node-red
    container_name: node-red
    hostname: node-red
    restart: unless-stopped
    healthcheck:
      disable: true
    environment:
      - PUID=1001
      - PGID=1001
      - TZ=Europe/Nicosia
    ports:
      - 1880:1880
    volumes:
      - ./config/node-red/:/data

I am looking for a way to automatically install the latest version of “node-red-contrib-home-assistant-websocket” when the container starts for the first time.

This is what I tried so far:

  1. Adding the module to the dependencies in package.json and enabling “autoInstall” in settings.js
{
    "name": "node-red-project",
    "description": "A Node-RED Project",
    "version": "0.0.1",
    "private": true,
    "dependencies": {
        "node-red-contrib-home-assistant-websocket": "~0.80.0"
    }
}

    externalModules: {
         autoInstall: true,   /** Whether the runtime will attempt to automatically install missing modules */
        // autoInstallRetry: 30, /** Interval, in seconds, between reinstall attempts */
        // palette: {              /** Configuration for the Palette Manager */
        //     allowInstall: true, /** Enable the Palette Manager in the editor */
        //     allowUpdate: true,  /** Allow modules to be updated in the Palette Manager */
        //     allowUpload: true,  /** Allow module tgz files to be uploaded and installed */
        //     allowList: ['*'],
        //     denyList: [],
        //     allowUpdateList: ['*'],
        //     denyUpdateList: []
        // },
        // modules: {              /** Configuration for node-specified modules */
        //     allowInstall: true,
        //     allowList: [],
        //     denyList: []
        // }
    },
  1. adding a command in the compose file
  command: >
    sh -c "npm install --no-audit --no-update-notifier --no-fund
    [email protected] && npm start -- --userDir /data"
  1. Adding an entrypoint in compose file
  entrypoint: >
    sh -c "npm install --prefix /data --no-audit --no-update-notifier --no-fund
    [email protected] &&
    exec npm start -- --userDir /data"

None of these option worked for me, and I really don’t want to maintain a custom node-red image in docker, just for this module.

Is there anything else I can try?
