大佬教程收集整理的这篇文章主要介绍了Windows 上连接虚拟机上docker的kafka报错unknown host，大佬教程大佬觉得挺不错的，现在分享给大家，也给大家做个参考。

Kafka Listeners - Explained

https://rmoff.net/2018/08/02/kafka-listeners-explained/

[thrd:kafka1:9092/1002]: kafka1:9092/1002: Failed to resolve 'kafka1:9092': 不知道这样的主机。 (after 2253ms in state CONNECT, 1 identical error(s) suppressed)

The brokers will advertise themselve using advertised.listeners (which seems to be abstracted with KAFKA_ADVERTISED_host_name in that docker imagE) and the clients will consequently try to connect to these advertised hosts and ports.

you will thus need to make sure the client can resolve and reach this advertised hostnames, e.g. by adding "kafka" to /etc/hosts on the client host.

192.168.0.11 是虚拟机上的IP，Windows Client 机上连不上虚拟机里面的docker网络172.20.0.14~16，而连接里必须跟KAFKA_ADVERTISED_LISTENERS的设置地址一样，在window上hosts文件设置

192.168.0.11 kafka1

192.168.0.11 kafka2

192.168.0.11 kafka3

public override void Configureservices(serviceConfigurationContext context)
        {
            Configure<AbpKafkaOptions>(options =>
            {
                //options.Connections.Default.bootstrapServers = "127.0.0.1:9092";
                options.Connections.Default.bootstrapServers = "kafka1:9092,kafka2:9093,kafka3:9094";
            });

            Configure<AbpKafkaEventBusOptions>(options =>
            {
                options.GroupId = "MyGroupId2";
                options.TopicName = "myTopicName";
