这里有一个轻量级的解决方案，可以避免在容器上安装任何X服务器，vnc服务器或sshd守护进程。它在简单中得到的好处，却在安全和隔离中失去了。

它假设您使用带有X11转发的ssh连接到主机。

在主机的sshd配置中添加该行

X11UseLocalhost no

因此，主机上转发的X服务器端口在所有接口上都是开放的(不仅仅是lo)，特别是在Docker虚拟接口docker0上。

容器在运行时需要访问. xauthority文件，以便连接到服务器。为此，我们定义了一个只读卷，指向主机上的主目录(可能不是一个明智的主意!)，并相应地设置XAUTHORITY变量。

docker run -v $HOME:/hosthome:ro -e XAUTHORITY=/hosthome/.Xauthority

这还不够，我们还必须从主机传递DISPLAY变量，但是用ip代替主机名:

-e DISPLAY=$(echo $DISPLAY | sed "s/^.*:/$(hostname -i):/")

我们可以定义一个别名:

 alias dockerX11run='docker run -v $HOME:/hosthome:ro -e XAUTHORITY=/hosthome/.Xauthority -e DISPLAY=$(echo $DISPLAY | sed "s/^.*:/$(hostname -i):/")'

然后像这样测试:

dockerX11run centos xeyes

OSX

Jürgen Weigert有最好的答案，在Ubuntu上为我工作，然而在OSX上，docker运行在VirtualBox内部，所以解决方案没有更多的工作就不能工作。

我让它和这些额外的配料一起工作:

Xquartz (OSX不再随X11服务器发货) 使用socat进行Socket转发 Bash脚本启动容器

我很感激用户的评论来改善OSX的这个答案，我不确定套接字转发X是否安全，但我的预期用途是只在本地运行docker容器。

此外，该脚本有点脆弱，因为它不容易获得机器的IP地址，因为它是在我们的本地无线，所以它总是一些随机的IP。

我用来启动容器的BASH脚本:

#!/usr/bin/env bash

CONTAINER=py3:2016-03-23-rc3
COMMAND=/bin/bash
NIC=en0

# Grab the ip address of this box
IPADDR=$(ifconfig $NIC | grep "inet " | awk '{print $2}')

DISP_NUM=$(jot -r 1 100 200)  # random display number between 100 and 200

PORT_NUM=$((6000 + DISP_NUM)) # so multiple instances of the container won't interfer with eachother

socat TCP-LISTEN:${PORT_NUM},reuseaddr,fork UNIX-CLIENT:\"$DISPLAY\" 2>&1 > /dev/null &

XSOCK=/tmp/.X11-unix
XAUTH=/tmp/.docker.xauth.$USER.$$
touch $XAUTH
xauth nlist $DISPLAY | sed -e 's/^..../ffff/' | xauth -f $XAUTH nmerge -

docker run \
    -it \
    --rm \
    --user=$USER \
    --workdir="/Users/$USER" \
    -v "/Users/$USER:/home/$USER:rw" \
    -v $XSOCK:$XSOCK:rw \
    -v $XAUTH:$XAUTH:rw \
    -e DISPLAY=$IPADDR:$DISP_NUM \
    -e XAUTHORITY=$XAUTH \
    $CONTAINER \
    $COMMAND

rm -f $XAUTH
kill %1       # kill the socat job launched above

我能够让xeyes和matplotlib使用这种方法工作。

Windows 7 +。

在Windows 7+上使用MobaXterm更容易一些:

为windows安装MobaXterm 开始MobaXterm 配置X服务器:“设置”—“> X11 (tab)”—“> X11远程访问”设置为“full” 使用这个BASH脚本启动容器

run_docker.bash:

#!/usr/bin/env bash

CONTAINER=py3:2016-03-23-rc3
COMMAND=/bin/bash
DISPLAY="$(hostname):0"
USER=$(whoami)

docker run \
    -it \
    --rm \
    --user=$USER \
    --workdir="/home/$USER" \
    -v "/c/Users/$USER:/home/$USER:rw" \
    -e DISPLAY \
    $CONTAINER \
    $COMMAND

这不是轻量级的，但是一个很好的解决方案，使docker特性与完整的桌面虚拟化相同。Ubuntu和CentOS的Xfce4或IceWM都可以工作，noVNC选项可以通过浏览器轻松访问。

https://github.com/ConSol/docker-headless-vnc-container

它运行noVNC以及tigerVNC的vncserver。然后它为给定的窗口管理器调用startx。此外，libss_wrapper . dll。用于模拟用户的密码管理。

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。

共享主机显示:0，正如在其他一些回答中所述，有两个缺点:

由于某些X安全漏洞，它打破了容器隔离。例如，可以使用xev或xinput进行键盘记录，使用xdotool远程控制主机应用程序。 由于X扩展MIT-SHM缺少共享内存，应用程序可能会出现呈现故障和糟糕的RAM访问错误。(也可以通过隔离降级选项——ipc=host进行修复)。

下面是一个在Xephyr中运行docker映像的示例脚本，可以解决这个问题。

当docker应用程序运行在嵌套的X服务器上时，它避免了X安全泄漏。 MIT-SHM关闭，避免RAM访问失败。 容器安全性通过——cap-drop ALL——security-opt no-new-privileges得到改进。容器用户也不是root用户。 创建一个X cookie来限制对Xephyr显示的访问。

脚本需要一些参数，第一个是在Xephyr中运行的主机窗口管理器，第二个是docker映像，第三个是可选的 要执行的映像命令。 要在docker中运行桌面环境，请使用“:”而不是主机窗口管理器。

关闭Xephyr窗口将终止docker容器应用程序。终止停靠的应用程序关闭Xephyr窗口。

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。
