Win10环境借助DockerDesktop部署大数据时序数据库Apache Druid-资源准备

参考官网：

https://druid.apache.org/docs/latest/tutorials/docker

官方给出了使用docker-compose.yml编排容器的教程，作为一个实时组件，大内存是必须的！！！但是启动8个容器【Zookeeper+PostgreSQL+6个Druid】每个最多7GB内存也不是什么大事！！！

获取到这个资源文件：

参照官网另一篇：

自己玩玩可以先不改这些运行时配置，容器启动的，后续要重新部署也非常容易！！！

还需要：

做另一个配置文件：

部署文件看起来麻雀虽小五脏俱全！！！
