原因

是nacos2.0后需要开放两个8848偏移后的端口
官网解释
https://nacos.io/zh-cn/docs/2.0.0-compatibility.html

Nacos2.0增加了9848，9849端口来进行GRPC通信，我需要在application.properties中额外配置吗？
不需要，这两个端口在Nacos2.0内部是通过8848+1000以及8848+1001这种偏移量方式计算出来的，不需要用户额外在配置文件中配置。但如果使用的是docker或存在端口转发方式启动，需要把这两个端口进行配置。

解决

所以在docker环境中我们需要开放8849 9848 9849 三个端口

docker run --name mynacos -d -p 8848:8848 -p 9848:9848 -p 9849:9849 --privileged=true --restart=always -e MODE=standalone -e PREFER_HOST_MODE=hostname nacos/nacos-server
