Docker 无法使用Sarama Golang软件包创建Kafka producer客户端-“；客户端/元数据在获取元数据时从代理处获取错误：EOF"；

版本：GoLang 1.10.2 卡夫卡4.4.1 Docker 18.03.1

我正在尝试使用Shopify的Sarama包来测试我的Kafka实例。我用Docker compose站起来让Kafka/Zookeeper站起来，一切都顺利运行

当我尝试使用Sarama创建Producer客户端时，会抛出一个错误

当我运行以下命令时

    package main

import (
"fmt"
"log"
"os"
"os/signal"
"time"

"strconv"

"github.com/Shopify/sarama"

)

我明白了

[sarama]2018/06/12 17:22:05初始化新客户

[sarama]2018/06/12 17:22:05客户端/元数据从代理本地主机获取所有主题的元数据：29092

[sarama]2018/06/12 17:22:05已连接到本地主机上的代理：29092（未注册）

[sarama]2018/06/12 17:22:05客户端/元数据在获取元数据时从代理获取错误：EOF

[sarama]2018/06/12 17:22:05已关闭与代理本地主机的连接：29092

{sarama]2018/06/12 17:22:05客户端/元数据没有可用的代理向其发送元数据请求

[sarama]2018/06/12 17:22:06关闭客户 恐慌：卡夫卡：客户端已经没有可用的代理可以与之交谈了（您的集群可以访问吗？）

goroutine 1[正在运行]： main.main（） /Users/benwornom/go/src/github.com/acstech/doppler events/testprod/main.go:29+0x3ec 退出状态2

Sarama确实连续几次尝试创建producer客户端，但每次都失败了

我对Sarama的“NewAsyncProducer”方法的理解是它调用“NewClient”，无论您是创建生产者还是消费者，都会调用它。NewClient尝试从Kafka代理收集元数据，这在我的情况下是失败的。我知道它正在连接到Kafka代理，但一旦连接，它似乎会断开。任何建议都会有帮助。我的网络连接很强，我想不出任何东西干扰服务器。据我所知，现有主题只有一个代理和一个分区。我认为我不必手动将主题分配给代理。如果我的客户端正在与代理连接，为什么我不能为我的制作者建立持久的连接

我遇到了同样的问题，我采取了以下措施解决了我的问题：

检查您正在使用的卡夫卡版本。当传递到

NewAsyncProducer

时，配置中指定的默认卡夫卡版本是

V0_8_2_0

。请确保在配置中指定正确的卡夫卡版本：

config := sarama.NewConfig()
config.Version = sarama.V1_1_0_0

确保您传递的代理URL是正确的。您应该传递代理URL，而不是zookeeper URL或其他URL。默认kafka端口为

9092

，因此如果使用默认端口，则URL应类似于

broker\u URL:9092

config := sarama.NewConfig()
config.Version = sarama.V1_1_0_0
