Question

为了启动一个kafka容器，我正在关注this guide。我正在开发win10 pro，我的cli是gitbash。

docker-compose-single-broker.yml：

version: '2'
services:
  zookeeper:
    image: wurstmeister/zookeeper
    ports:
      - "2181:2181"
  kafka:
    image: wurstmeister/kafka 
    ports:
      - "9092:9092"
    environment:
      KAFKA_ADVERTISED_HOST_NAME: localhost
      KAFKA_CREATE_TOPICS: "test:1:1"
      KAFKA_ZOOKEEPER_CONNECT: zookeeper:2181
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock

容器启动没有任何问题：

$ docker-compose -f docker-compose-single-broker.yml up -d
Creating kafka-docker_zookeeper_1 ... done
Creating kafka-docker_kafka_1     ... done

$ docker ps
CONTAINER ID        IMAGE                    COMMAND                  CREATED             STATUS              PORTS                                                NAMES

但是，当我尝试从容器内部运行任何kafka命令（创建主题，列出主题）时，如下所示：

> $KAFKA_HOME/bin/kafka-topics.sh --create --topic test --partitions 1 --replication-factor 1 --bootstrap-server `broker-list.sh`
> $KAFKA_HOME/bin/kafka-topics.sh --describe --topic test --bootstrap-server `broker-list.sh`

我收到以下警告，然后出现超时异常：

$ ./start-kafka-shell.sh localhost
bash-4.4# $KAFKA_HOME/bin/kafka-topics.sh --create --topic test --partitions 1 --replication-factor 1 --bootstrap-server `broker-list.sh`

start-kafka-shell.sh的内容：

$ cat start-kafka-shell.sh
#!/bin/bash
docker run --rm -v //var/run/docker.sock:/var/run/docker.sock -e HOST_IP=$1 -e ZK=$2 -i -t wurstmeister/kafka /bin/bash

我不确定start-kafka-shell.sh的目的是什么。如果您使用的是Docker，则可以按照以下说明从Windows Shell与之交互：

docker exec -it tmp_kafka_1 bash -c '$KAFKA_HOME/bin/kafka-topics.sh --create --topic test4 --partitions 1 --replication-factor 1 --bootstrap-server `broker-list.sh`'


docker exec -it tmp_kafka_1 bash -c '$KAFKA_HOME/bin/kafka-topics.sh --describe --topic test4 --bootstrap-server `broker-list.sh`'

Topic: test4    PartitionCount: 1       ReplicationFactor: 1    Configs: segment.bytes=1073741824
        Topic: test4    Partition: 0    Leader: 1001    Replicas: 1001  Isr: 1001

您只需要正确的Docker容器名称（在上面的示例中为tmp_kafka_1），即可使用docker ps进行确认。

kafka容器-无法建立到节点-1的连接（localhost / 127.0.0.1：9092）。经纪人可能不可用
