在香港VPS服務器的docker中部署kafka集群通常需要使用docker Compose來管理多個容器。以下是一個簡單的示例，通過docker Compose來部署一個包含3個kafka節點和1個zookeeper節點的kafka集群。

1、創建一個docker Compose配置文件docker-compose.yaml：

version: ‘3’

services:

zookeeper:

image: wurstmeister/zookeeper

ports:

– 2181:2181

kafka1:

image: wurstmeister/kafka

ports:

– 9092:9092

environment:

kafka_ADVERTISED_LISTENERS: INSide://kafka1:9093,OUTSide://localhost:9092

kafka_LISTENER_SECURITY_PROTOCOL_MAP: INSide:PLaiNTEXT,OUTSide:PLaiNTEXT

kafka_LISTENERS: INSide://0.0.0.0:9093,OUTSide://0.0.0.0:9092

kafka_intER_BROKER_LISTENER_NAME: INSide

kafka_zookeeper_CONNECT: zookeeper:2181

kafka_CREATE_TOPICS: “test:1:1”

links:

– zookeeper

kafka2:

image: wurstmeister/kafka

environment:

kafka_BROKER_ID: 1

kafka_ADVERTISED_LISTENERS: INSide://kafka2:9093,OUTSide://localhost:9094

kafka_LISTENER_SECURITY_PROTOCOL_MAP: INSide:PLaiNTEXT,OUTSide:PLaiNTEXT

kafka_LISTENERS: INSide://0.0.0.0:9093,OUTSide://0.0.0.0:9094

kafka_INTER_BROKER_LISTENER_NAME: INSide

kafka_zookeeper_CONNECT: zookeeper:2181

links:

– zookeeper

kafka3:

image: wurstmeister/kafka

environment:

kafka_BROKER_ID: 2

kafka_ADVERTISED_LISTENERS: INSide://kafka3:9093,OUTSide://localhost:9095

kafka_LISTENER_SECURITY_PROTOCOL_MAP: INSide:PLaiNTEXT,OUTSide:PLaiNTEXT

kafka_LISTENERS: INSide://0.0.0.0:9093,OUTSide://0.0.0.0:9095

kafka_INTER_BROKER_LISTENER_NAME: INSide

kafka_zookeeper_CONNECT: zookeeper:2181

links:

– zookeeper

2、在命令行中使用docker Compose啟動kafka集群：

docker-compose up

這將啟動zookeeper節點和三個kafka節點。您可以通過訪問localhost:9092，localhost:9094和localhost:9095來訪問這三個kafka節點。

請注意，這只是一個簡單的示例，實際部署可能需要更多的配置和調整。您可能還需要做一些額外的配置，如數據卷、網絡配置等。建議查看kafka和docker的官方文檔以獲取更多詳細的信息。
