Spring Kafka Producer not sending to Kafka 1.0.0 (Magic v1 does not support record headers)

Question

I am using this docker-compose setup for setting up Kafka locally: https://github.com/wurstmeister/kafka-docker/

docker-compose up works fine, creating topi

Answer 1

I just ran a test against that docker image with no problems...

$docker ps

@SpringBootApplication
public class So47953901Application {

    public static void main(String[] args) {
        SpringApplication.run(So47953901Application.class, args);
    }

    @Bean
    public ApplicationRunner runner(KafkaTemplate template) {
        return args -> template.send("foo", "bar", "baz");
    }

    @KafkaListener(id = "foo", topics = "foo")
    public void listen(String in) {
        System.out.println(in);
    }

}

EDIT

Still works for me...
