如何在Linux Docker容器中运行GUI应用程序?

是否有任何图像设置vncserver或其他东西,以便您可以-例如-在Firefox周围添加额外的加速沙箱?


当前回答

我刚刚发现了这篇博客,想在这里与你们分享,因为我认为这是最好的方法,而且很简单。

http://fabiorehm.com/blog/2014/09/11/running-gui-apps-with-docker/

优点: + docker容器中没有x服务器的东西 +不需要VNC客户端/服务器 + SSH不支持x转发 +更小的docker容器

缺点: 在主机上使用x(不是为了安全沙箱)

以防链接有一天会失败,我把最重要的部分放在这里: dockerfile:

FROM ubuntu:14.04

RUN apt-get update && apt-get install -y firefox

# Replace 1000 with your user / group id
RUN export uid=1000 gid=1000 && \
    mkdir -p /home/developer && \
    echo "developer:x:${uid}:${gid}:Developer,,,:/home/developer:/bin/bash" >> /etc/passwd && \
    echo "developer:x:${uid}:" >> /etc/group && \
    echo "developer ALL=(ALL) NOPASSWD: ALL" > /etc/sudoers.d/developer && \
    chmod 0440 /etc/sudoers.d/developer && \
    chown ${uid}:${gid} -R /home/developer

USER developer
ENV HOME /home/developer
CMD /usr/bin/firefox

构建映像:

docker build -t firefox .

run命令:

docker run -ti --rm \
   -e DISPLAY=$DISPLAY \
   -v /tmp/.X11-unix:/tmp/.X11-unix \
   firefox

当然,你也可以在运行命令中使用sh -c "echo script-here"

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

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。

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。

待办事项:没有音频。——device /dev/snd没有帮助:

测试:

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。

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
