Docker 网络

确认 nacos_net 网络是否已经正确连接到两个容器 nacos、mysql

sudo docker network inspect nacos_net

"Containers": {} 部分为空，代表目前没有任何容器连接到该网络

    }

如果启动服务后仍然无法创建网络，可以手动创建它

sudo docker network create nacos_net

重启 Docker Compose 服务

sudo docker compose down
sudo docker compose up -d

Docker网络模式

桥接模式 (bridge)

这是Docker的默认模式。每个容器都会连接到一个虚拟网桥（如docker0），并从该网桥中获取IP地址。容器之间可以通过这个虚拟网桥进行通信。
