Kafka-Node not detecting kafka broker - docker

Question

I'm currently using Kafka-node in my application but I cant manage to connect it to the Kafka broker I have brought up before hand.
Firstly, I bring up the kafka broker with the wurstmeister/kafka docker image. I also bring zookeeper up with the jplock/zookeeper image.
I thne automatically create a topic with an environment variable with the wurstmeister/kafka image. like so:
zookeeper:
image: jplock/zookeeper
ports:
- "2181:2181"
networks:
- bitmex_backend
kafka:
image: wurstmeister/kafka:latest
ports:
- "9092:9092"
depends_on:
- zookeeper
environment:
KAFKA_ADVERTISED_HOST_NAME: localhost
KAFKA_ZOOKEEPER_CONNECT: zookeeper:2181
KAFKA_LISTENERS: "PLAINTEXT://:9092"
KAFKA_ADVERTISED_LISTENERS: PLAINTEXT://localhost:9092
KAFKA_CREATE_TOPICS: "Topic1:1:1"
networks:
- bitmex_backend
I verify the container is up by listing all the topics from kafka which returns the correct number and name of topics.
I then want to bring up a producer and verify its up when I call an endpoint so I do:
// Import the WebFramework for routing
const Koa = require('koa')
const route = require('koa-route')
var kafka = require('kafka-node');
client = new kafka.Client(),
producer = new kafka.Producer(client);
// TODO : Generate a position/history endpoint
module.exports = async () => {
const app = new Koa()
// Retrive all the open positions from all the bots in the system
app.use(route.get('/open', async (ctx) => {
producer.on('ready', function () {
console.log('Producer is ready');
});
producer.on('error', function (err) {
console.log('Producer is in error state');
console.log(err);
})
// Response
ctx.status = 200
ctx.body = {
data : "success",
}
}))
return app
This code runs with out errors but no output either. Whn I check the logs the endpoint is called correctly with no console.log to prove that the endpoint has loaded.
Any ideas or pointers are very welcomed as I've been stuck with this for a while now.
