Я запускаю Eclipse Mosquitto в локальном docker контейнере 172.17.0.2:1883
Я могу публиковать / подписываться с помощью клиента MQTT.fx, но теперь пытаюсь подключиться к брокеру с узла и
topi c - это "датчики"

Когда я проверяю IP-адрес
docker inspect -f '{{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}}' e747c86b6ec1
172.17.0.2
Я пытаюсь используйте следующий сервер узлов для подключения к моему MQTT-брокеру, но, похоже, событие 'connect' никогда не происходит.
// Note: I have an express server running but didn't include
const mqtt = require("mqtt")
var MQTT_TOPIC = "sensors";
var MQTT_ADDR = "mqtt://172.17.0.2";
var MQTT_PORT = 1883;
var client = mqtt.connect(MQTT_ADDR, {
port: MQTT_PORT,
clientId: 'bgtestnodejs232323',
protocolId: 'MQIsdp',
protocolVersion: 3,
connectTimeout: 1000,
debug: true
});
client.on('connect', function () {
console.log("connected!")
});
client.on('error', function (err) {
console.log(err)``
client.end()
})
Когда я запускаю:
console.log(util.inspect(client))

Я пробовал предложения в этом ответе: Почему MQTT не соединяется с NodeJS?
Спасибо за вашу помощь!
