[Dúvida] Erro ao estabelecer conexão do Java com o Docker

Boa noite pessoal,

Estou fazendo o curso de Apache Kafka e na parte de implementar o KafkaProducer em Java estou com erros, segue abaixo o meu fonte em Java:

package br.com.alura;

import java.util.Properties;
import java.util.concurrent.ExecutionException;

import org.apache.kafka.clients.producer.KafkaProducer;
import org.apache.kafka.clients.producer.ProducerConfig;
import org.apache.kafka.clients.producer.ProducerRecord;
import org.apache.kafka.common.serialization.StringSerializer;

public class NewOrderMain {
    public static void main(String[] args) throws ExecutionException, InterruptedException {
        var producer = new KafkaProducer<String, String>(properties());
        var value = "1,1,500.00";
        var record = new ProducerRecord<>("ECOMMERCE_NEW_ORDER",value, value);
        producer.send(record, (data, ex) -> {
            if (ex != null) {
                ex.printStackTrace();
                return;
            }
            System.out.println("sucesso enviando neste topico" + data.topic() + ":::partition " + data.partition() + "/ offset" + data.offset() + "/ timestamp " + data.timestamp());
        }).get();
    }

    private static Properties properties() {
        var properties = new Properties();
        properties.setProperty(ProducerConfig.BOOTSTRAP_SERVERS_CONFIG, "127.0.0.1:9092"); //Estabelecer conexão com servidor Kafka
        properties.setProperty(ProducerConfig.KEY_SERIALIZER_CLASS_CONFIG, StringSerializer.class.getName()); //Serializador de String para byte para a Key do Map
        properties.setProperty(ProducerConfig.VALUE_SERIALIZER_CLASS_CONFIG, StringSerializer.class.getName()); //Serializador de String para byte para o Value do Map
        return properties;
    }
}

Segue o arquivo Pom XML:

Estou rodando o Kafka em um Container no Docker, a mensagem de erro que aparece ao compilar e executar o programa é:
