centraldogma 支持ha模式的运行（依赖zk），以下是参考配置
version: "3"
services:
app:
image: line/centraldogma
volumes:
- "./shiro.ini:/opt/centraldogma/conf/shiro.ini"
- "./dogma.json:/opt/centraldogma/conf/dogma.json"
ports:
- "36462:36462"
app2:
image: line/centraldogma
volumes:
- "./shiro.ini:/opt/centraldogma/conf/shiro.ini"
- "./dogma2.json:/opt/centraldogma/conf/dogma.json"
ports:

ports:
- "36464:36462"

数据 
centraldogma 的ha 使用了内嵌模式的zk，或者部署起来还是比较方便的（但是注意如果使用了容器数据持久化必须做）,以下是参考的数据格式
（容器内部存储，内嵌zk的数据目录）
