ruoyi-cloud docker启动微服务无法连接nacos，Client not connected, current status:STARTING
场景
当使用sh deploy.sh base来安装mysql、redis、nacos环境后，紧接着使用sh deploy.sh modules安装微服务模块，会发现微服务无法连接nacos的情况，报错为

分析原因
docker compose搭建的docker容器中，一个容器不应该使用localhost来访问另一个容器，例如在微服务模块中配置
# 服务注册地址
server-addr: 127.0.0.1:8848
这样在容器中是无法访问到nacos的
应该改为：
# 服务注册地址
server-addr: ruoyi-nacos:8848
对应所有位置都需要修改
修改后微服务容器成功启动
