+架构是将Rust编译环境和Web服务器（包括前端UI）分为两个独立的Docker镜像，并且这两个镜像之间可以相互通信。
+
+4. 构建和运行
+
+在项目的根目录下运行以下命令来构建和启动所有服务：
+
+bash
+深色版本
+
+docker-compose up --build
+
+这将会构建所有的Docker镜像，并启动相应的容器。你可以通过访问http://localhost来查看前端界面，并尝试编译Rust代码。
+
+#查看端口占用和结束端口进程
+sudo lsof -i :80
+
+sudo kill -9 <PID>
+
+#删除镜像重建镜像
+
+重新构建和运行
+
+在项目的根目录下运行以下命令来构建和启动所有服务：
