# yaml规则 #

docker-compose.yaml核心

# 3层
    
    # 第一层
    # 版本
    version: ''
     
    # 第二层 
    # 服务
    service:
        服务1：web服务
            # 服务配置(docker容器配置)
            images
            build
            network
            .....
        服务2：redis服务
    
    # 第三层
    # 其他配置 网络/全局规则
    volumes:
    network:
    configs:

# 在service中 项目是有顺序的所以说得需要加入依赖
     depends_on:
        - dolphinscheduler-api
