⁠Docker Images

docker run -d --restart=always --pull=always --network=host -v nodereddata:/data --name mynodered noycebe/netfield-node-red:<tag>
⁠netFIELD Container Create Options
{
  "HostConfig": {
    "Privileged": true,
    "NetworkMode": "host",
    "PortBindings": {
      "1880/tcp": [
        {
          "HostPort": "1880"
        }
      ]
    },
    "Mounts": [
      {
        "Type": "volume",
        "Source": "nodered",
        "Target": "/data",
        "ReadOnly": false,
        "Consistency": "consistent"
      }
    ]
  }
}
⁠Network Host Mode

The container must be run in host mode, otherwise the authentication will fail. In the user-authentication_v2.js the IP is 127.0.0.1 (localhost) to check for authentication. In bridge mode, this IP address needs to be adapted.

⁠Installed Node Modules

node-red-contrib-opcua
node-red-contrib-influxdb
node-red-contrib-modbus
node-red-dashboard
node-red-node-serialport

⁠Changes in Node-RED standard files

⁠set authentication to netFIELD V2
adminAuth: require("/data/user-authentication_v2.js"),
⁠enable https security and make certificates known
https: {
    key: require("fs").readFileSync('/data/certs/node-key.pem'),
    cert: require("fs").readFileSync('/data/certs/node-cert.pem')
},
⁠redirect insecure HTTP connections to HTTPS
requireHttps: true,
