彦祖们，我使用这个仓库： https://github.com/nacos-group/nacos-docker/blob/master/README_ZH.md

提供的 docker-compose.yml 去启动 nacos 集群

日志显示 nacos 启动正常了

但是我怎么访问 nacos 的控制台呢？

http://127.0.0.1:8848/nacos/index.html 访问不了

http://nacos1:8848/nacos/index.html 更访问不了（因为我压根没有 nacos1 这个 host ）

我本地 ifconfig 显示有多个网卡

本质上还是对 docker 不熟悉。求彦祖解答，比心♥️

docker ps 看看，看启动的容器有没有配置端口映射

netstat -tunlp | grep 8848 查看一下端口

docker 用的自己的 bridge ，和宿主机网络是隔开的，你映射端口没，docker exec 到容器里面看看 127.0.0.1 可以访问不

可能是 iptables 的问题，重启下 docker 看看

破案了，哥哥们，是 nacos jvm 内存设置太大导致的
