以下是启动支持 SSL 的 kafka docker-compose 的步骤(@Senthil 已经在他的评论中提供了一些指导)

• 在 docker-compose 目录中有一个所谓的 secrets 目录，其中包含用于生成 keystore 、信任库和 ssl 密码的 shell 脚本。进入 kafka 的 docker-compose 的根目录并运行将生成所需文件的脚本(例如:./secrets/create-certs)

• 将所有生成的文件复制到secrets目录

• 将 secrets 目录的卷从主机挂载到 dockerized 的主机。将以下内容放在卷部分的 docker-compose 文件中

volumes:
  - ./secrets/:/etc/kafka/secrets

使用 docker-compose up 运行
