docker-compose方式启动Kafka Sasl加密认证(无zk)

news 2025/9/13 10:59:24

首先参考文档，思考过程可以进行参考https://juejin.cn/post/7294556533932884020#heading-3

用的镜像是Bitnami，对SASL配置进行了简化，需要按照特定格式去配置jass验证
完整配置如下
镜像版本参考：https://hub.docker.com/r/bitnami/kafka/tags

KAFKA_KRAFT_CLUSTER_ID这里需要固定一个uuid

# 使用Linux工具生成Kafka格式的集群ID
UUID=$(uuidgen | tr -d '-')
echo $UUID | xxd -r -p | base64

启动以后宿主机kafka的目录结构如下

tree kafka/
kafka/
└── kafka├── config└── data

我最终选择一个固定版本，防止某天重启后发生异常错误

对容器的kafka用户进行授权

chown 1001:1001 /data/kafka/docker-compose down && docker-compose up -d

测试用户名密码连接
