3.启动容器

1

ksnowlv@MacBook-Pro-3 LinuxFlutter %  docker run -it  -e DISPLAY=host.docker.internal:0  -v /tmp/.X11-unix:/tmp/.X11-unix  --name flutter_nogl  flutter_nogl /bin/bash

上述命令启动了一个名为flutter_nogl的容器，并将其设置为交互式容器（-it 选项）。

docker run: 运行一个新的容器

-it: 指定交互式执行，通常用于需要交互的命令行应用程序
-e DISPLAY=host.docker.internal:0: 设置名为 DISPLAY 的环境变量，用于指定容器内的图形界面显示到宿主机的X服务器。host.docker.internal 是Docker针对宿主机的主机名，0 则表示 X 服务器的显示编号。
-v /tmp/.X11-unix:/tmp/.X11-unix: 将宿主机的 X11 UNIX 域套接字（指向 X 服务器的通信管道）映射到容器内的相同位置。这允许容器内的应用程序连接到宿主机的 X 服务器以显示图形界面。
–name flutter_nogl: 为容器指定一个名称，即 flutter_nogl flutter_nogl: 要使用的镜像名称，也即您要从其中启动容器的镜像名称
/bin/bash: 在容器内启动的命令，这里是启动一个 bash shell 综合起来，这个命令的目的是创建一个带有图形界面的容器，允许在其中执行需要图形界面的命令或应用程序。通常情况下，这样的容器会用于运行需要图形界面的应用程序或者开发环境，比如在容器内运行带有图形界面的Flutter开发环境

4.Mac安装XQuartz，并完成允许从网络客户端连接设置

从https://www.xquartz.org下载XQuartz，并完成安装。

在Mac应用程序中，找到实用工具中的XQuartz，并打开。

在XQuartz的偏好设置中，选择安全性选项卡，然后，勾选“鉴定连接”和“允许从网络客户端连接”，确保这两项选中。然后，重启XQuartz，使设置生效。

ksnowlv@MacBook-Pro-3 base_demo % xhost +
access control disabled, clients can connect from any host
ksnowlv@MacBook-Pro-3 base_demo % xeyes

XQuartz返回上述信息就代表，已完成设置；输入xeyes你将看到鼠标的眼睛。

5. VSCode打开容器中的hello_world工程

VSCode 安装docker插件，安装完成后， control+option+p ，选择Docker：焦点在 Containers 视图上 Docker: Focus on Containers View，并打开。

6.效果

右击运行的容器，并打开附加 Visual Studio Code；启动vscode后，运行linux应用

能跑起来，报错libGL error: No matching fbConfigs or visuals found libGL error: failed to load driver: swrast知道是OPENGL出错了，试了许多办法，无效果。

有知道的，还请指点。
