如何在docker中运行qt gui？

我尝试了几种解决方案，但不可避免地遇到以下错误：

$ QT_GRAPHICSSYSTEM="native" sudo docker run -it --privileged -e DISPLAY=$DISPLAY -e QT_GRAPHICSSYSTEM="native" -e QT_X11_NO_MITSHM=1 -v /dev:/dev -v /tmp/.X11-unix:/tmp/.X11-unix:rw qt-alpine

qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found.
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

Available platform plugins are: eglfs, linuxfb, minimal, minimalegl, offscreen, vnc, xcb.

主机系统：Ubuntu20.04和nvidia

Dockerfile：

FROM alpine:latest

RUN apk update && apk add --no-cache qt5-qtbase-dev qt5-qttools qt5-qt3d-dev g++ cmake make

WORKDIR /app

COPY . .

RUN qmake-qt5 && make

CMD ["sh", "-c", "QT_DEBUG_PLUGINS=1 QT_GRAPHICSSYSTEM=native /app/simple-qml/simple-qml"]

---

我只是想利用

qt5.15

和

3detras

等功能。在

qml

中提供支持。因此，这些文件只是目录中

qt3d5 examples

中的示例。所以实际上，这些文件并不重要，我只是在尝试建立运行

qt

-

opengl

-app in

docker
