30分鐘帶你搞定Dokcer部署Kafka集群

docker網路規劃

docker network create kafka-net --subnet 172.20.0.0/16

docker network ls

zookeeper1（172.20.0.11 2184:2181）
zookeeper2（172.20.0.12 2185:2181）
zookeeper3（172.20.0.13 2186:2181）
kafka（172.20.0.14 內部9093:9093，外部9193:9193）
kafka（172.20.0.15 內部9094:9094，外部9194:9194）
kafka（172.20.0.16 內部9095:9095，外部9195:9195）
kafka manager（172.20.0.10 9000:9000）

部署中的配置和授權認證文件製作

準備一下兩個文件，他們的位置可以放到任意地方，只需要鏡像部署的配置文件中能引用到即可。

新建一個zookeeper和kafka共用的授權認證文件：server_jass.conf。按照本教程建議放到/root/kafka/kafka-sasl/server_jass.conf

Client {
    org.apache.zookeeper.server.auth.DigestLoginModule required
    username="test"
    password="test@QWER";
};

Server {
    org.apache.zookeeper.server.auth.DigestLoginModule required
    username="test"
    password="test@QWER"  
    user_admin="test@QWER"
    user_test="test@QWER"; # 賬號是test，密碼是test@QWER
};

KafkaServer {
    org.apache.kafka.common.security.plain.PlainLoginModule required
    username="test"
    password="test@QWER"
    user_test="test@QWER";
};

KafkaClient {
    org.apache.kafka.common.security.plain.PlainLoginModule required
    username="test"
    password="test@QWER";
};

新建一個kafka-run-class腳本文件，規避JMX衝突：kafka-run-class.sh。按照本教程建議放到/root/kafka/kafka-run-class.sh
