Xauthority becomes an issue with newer systems. I can either discard any protection with xhost + before running my docker containers, or I can pass in a well prepared Xauthority file. Typical Xauthority files are hostname specific. With docker, each container can have a different host name (set with docker run -h), but even setting the hostname of the container identical to the host system did not help in my case. xeyes (I like this example) simply would ignore the magic cookie and pass no credentials to the server. Hence we get an error message 'No protocol specified Cannot open display'

Xauthority文件的编写方式可以使主机名无关紧要。 我们需要将认证家族设置为“FamilyWild”。我不确定xauth是否有合适的命令行，所以这里有一个结合xauth和sed的示例。我们需要改变nlist输出的前16位。FamilyWild的值为65535或0xffff。

docker build -t xeyes - << __EOF__
FROM debian
RUN apt-get update
RUN apt-get install -qqy x11-apps
ENV DISPLAY :0
CMD xeyes
__EOF__
XSOCK=/tmp/.X11-unix
XAUTH=/tmp/.docker.xauth
xauth nlist :0 | sed -e 's/^..../ffff/' | xauth -f $XAUTH nmerge -
docker run -ti -v $XSOCK:$XSOCK -v $XAUTH:$XAUTH -e XAUTHORITY=$XAUTH xeyes

fcwu/docker-ubuntu-vnc-desktop (Ubuntu 18.04, 20.04)

https://github.com/fcwu/docker-ubuntu-vnc-desktop provides a convenient setup. That setup is not minimized. It would be good to minimize it. But I just don't have the time, and that one just works every time I try, so I tend to just use it. On the upside, because it is not minimized, it tends to test more complex programs you might actually to see that they are actually working through the infinitely many pitfalls of Docker. Also, since setups breaks on every guest/host update, a minimization would arguably only work for a limited period until you'd have to reminimize that project again.

要启动它，只需运行:

sudo docker run --name ubvnc -p 6080:80 -p 5900:5900 dorowu/ubuntu-desktop-lxde-vnc:focal

然后在主机上:

visit: http://127.0.0.1:6080/#/ which runs a noVNC more limited JavaScript VNC client run: sudo apt-get install tigervnc-viewer xtigervncviewer :5900 To go into fullscreen mode, hit F8 and click on menu entry, or just F8 followed by T: https://superuser.com/questions/285843/how-do-i-switch-in-out-of-fullscreen-mode-from-the-command-line-in-realvnc You might need to close and reopen the screen after that for the image to get larger. I also tried vinagre, but it was much laggier when scrolling Firefox on YouTube. Inside vinagre, you might want to go into full screen mode to be able to see the full desktop

要退出，只需杀死码头码头。并重新启动机器:

sudo docker start ubvnc

然后重新连接VNC。然后退出机器:

sudo docker stop ubvnc

您必须等待几秒钟，等待客户机上的VNC服务器启动，然后才能进行连接。

客人体内的铬不会从菜单开始。如果你试图从命令行启动它，它会解释为什么:

Running as root without --no-sandbox is not supported. See https://crbug.com/638180.

所以只需从CLI运行它:

chromium-browser --no-sandbox

然而，Firefox并不在意。

如何在Docker映像中打开Ubuntu GUI

测试:

Ubuntu 19.04主机，fcwu/docker-ubuntu-vnc-desktop, dorowu/ Ubuntu -desktop-lxde-vnc镜像id: 70516b87e92d。 Ubuntu 21.10主机:dorowu/ Ubuntu -desktop-lxde-vnc:focal (Ubuntu 20.04)

上帝还有另一个解决办法。在容器中运行GUI应用程序，而不使用VNC, SSH和X11转发。这里也提到了。

我来晚了，但对于不想走XQuartz道路的Mac用户，这里有一个工作示例，它使用Xvfb和VNC使用桌面环境(xfce)构建Fedora映像。这很简单，也很有效:

https://github.com/ddual/docker_recipes#fedora-with-an-x-window-system https://github.com/ddual/docker_recipes/tree/master/fedora_gui

在Mac上，您可以使用屏幕共享(默认)应用程序访问它，连接到localhost:5901。

Dockerfile：

FROM fedora

USER root

# Set root password, so I know it for the future
RUN echo "root:password123" | chpasswd

# Install Java, Open SSL, etc.
RUN dnf update -y --setopt=deltarpm=false  \
 && dnf install -y --setopt=deltarpm=false \
                openssl.x86_64             \

                @xfce-desktop-environment  \
 && dnf clean all

# Create developer user (password: password123, uid: 11111)
RUN useradd -u 11111 -g users -d /home/developer -s /bin/bash -p $(echo password123 | openssl passwd -1 -stdin) developer

# Copy startup script over to the developer home
COPY start-vnc.sh /home/developer/start-vnc.sh
RUN chmod 700 /home/developer/start-vnc.sh
RUN chown developer.users /home/developer/start-vnc.sh

# Expose VNC, SSH
EXPOSE 5901 22

# Set up VNC Password and DisplayEnvVar to point to Display1Screen0

ENV  DISPLAY :1.0
RUN  mkdir ~/.x11vnc
RUN  x11vnc -storepasswd letmein ~/.x11vnc/passwd

WORKDIR /home/developer
CMD ["/home/developer/start-vnc.sh"]

start-vnc.sh

#!/bin/sh

如果需要，请查看链接的自述文件以获得构建和运行命令。

你可以简单地安装一个vncserver和Firefox:)

我推了一个图像，vnc/firefox，在这里:docker拉creack/firefox-vnc

图片是用Dockerfile制作的:

# Firefox over VNC
#
# VERSION               0.1
# DOCKER-VERSION        0.2

FROM    ubuntu:12.04
# Make sure the package repository is up to date
RUN     echo "deb http://archive.ubuntu.com/ubuntu precise main universe" > /etc/apt/sources.list
RUN     apt-get update

# Install vnc, xvfb in order to create a 'fake' display and firefox
RUN     apt-get install -y x11vnc xvfb firefox
RUN     mkdir ~/.vnc
# Setup a password
RUN     x11vnc -storepasswd 1234 ~/.vnc/passwd
# Autostart firefox (might not be the best way to do it, but it does the trick)
RUN     bash -c 'echo "firefox" >> /.bashrc'

这将创建一个运行VNC的Docker容器，密码为1234:

对于Docker 18或更新版本:

docker run -p 5900:5900 -e HOME=/ creack/firefox-vnc x11vnc -forever -usepw -create

对于Docker 1.3或更新版本:

docker run -p 5900 -e HOME=/ creack/firefox-vnc x11vnc -forever -usepw -create

对于1.3版本之前的Docker:

docker run -p 5900 creack/firefox-vnc x11vnc -forever -usepw -create

您也可以使用subuser: https://github.com/timthelion/subuser

这允许你在docker中打包许多gui应用程序。到目前为止，Firefox和emacs已经进行了测试。然而，在firefox中，webGL却不能正常工作。铬根本不起作用。

编辑:声音工作!

EDIT2:自从我第一次发布这篇文章以来，subbuser已经取得了很大的进步。我现在有了一个subuser.org网站，以及一个通过XPRA桥接连接到X11的新安全模型。
