com.alibaba.nacos.api.exception.NacosException: Client not connected, current status:STARTING

如果nacos在运行的时候报这个错，然后你自己访问本地的nacos没有问题那么你得考虑一下版本问题(高版本一般不需要考虑)，然后就是端口的问题，因为在nacos的2.*之后有新的grpc的特性引入所以你得特别注意还得开启两个rpc的端口这样才不会报错，尤其是docker的环境下特别注意开启这两个端口：

docker run --name nacos -e MODE=standalone -p 8848:8848 -p 9848:9848 -p 9849:9849 nacos/nacos-server

其他的docker的配置如下：

# spring
server.servlet.contextPath=${SERVER_SERVLET_CONTEXTPATH:/nacos}
server.contextPath=/nacos
server.port=${NACOS_APPLICATION_PORT:8848}
