我想按照文档中的规定使用docker启动Confluence控制中心：

https://docs.confluence.io/platform/current/quickstart/ce-docker-quickstart.html

这是docker-compose.yaml他们提供的文件；

Confluence 控制中心未启动。

我执行了以下命令来启动 Confluence 平台

1. Zookeeper 启动（1 号航站楼）
2. Kafka 启动（2 号航站楼）

3. 模式注册表启动（终端 3）

4. 然后我尝试启动控制中心（4 号航站楼）。但出现错误。它没有开始。

出于开发目的，我想为我的单一经纪人 kafka 设置控制中心，但由于异常而失败。我将我的配置和控制中心输出日志详细信息放在这里。有人可以帮忙提供建议吗？
