问题描述
此问题是由。
其基本思想是运行具有音频和UI(VLC,火狐,SKYPE,...)
The basic idea is to run apps with audio and ui (vlc, firefox, skype, ...)
我正在寻找使用了PulseAudio泊坞窗容器,但所有的容器,我发现用在哪里流的PulseAudio通过TCP。
(应用程序安全沙箱)
I was searching for docker containers using pulseaudio but all containers I found where using pulseaudio streaming over tcp.(security sandboxing of the applications)
在我来说,我会prefere从应用程序直接播放音频容器内到我的主机的pulseaudio。 (不SSH隧道和臃肿泊坞窗图片)
In my case I would prefere playing audio from an app inside the container directly to my host pulseaudio. (without ssh tunneling and bloated docker images)
pulseaudio的,因为我的Qt应用程序使用它;)
Pulseaudio because my qt app is using it ;)
推荐答案
我花了一些时间,直到我发现需要什么。 (Ubuntu的)
it took me some time until i found out what is needed. (Ubuntu)
我们先从泊坞窗运行命令泊坞窗运行-ti --rm myContainer中的sh -c回声运行的东西
we start with the docker run command docker run -ti --rm myContainer sh -c "echo run something"
ALSA:结果
我们需要的/ dev / SND
和一些硬件的访问,因为它看起来像。
当我们把这个在一起,我们有
ALSA:
we need /dev/snd
and some hardware access as it looks like.when we put this together we have
docker run -ti --rm \
-v /dev/snd:/dev/snd \
--lxc-conf='lxc.cgroup.devices.allow = c 116:* rwm' \
myContainer sh -c "echo run something"`
的PulseAudio:结果
在这里我们需要基本的/ dev / shm的
,的/ etc /机器ID
和 /运行/用户/ $ UID /脉冲
。但是,这并不是所有的(因为的Ubuntu也许,以及他们如何做到了过去)。该envirorment变量 XDG_RUNTIME_DIR
必须在主机系统和在码头工人的容器一样。您可能还需要的/ var / lib中/ DBUS
,因为一些应用程序正在访问从这里机器ID(可能只包含一个符号链接到真正的机器ID)。至少,你可能需要隐藏的主文件夹〜/ .pulse
对于一些临时数据(我不知道这个)。
PULSEAUDIO:
Here we need basically /dev/shm
, /etc/machine-id
and /run/user/$uid/pulse
. But that is not all (maybe because of Ubuntu and how they did it in the past). The envirorment variable XDG_RUNTIME_DIR
has to be the same in the host system and in your docker container. You may also need /var/lib/dbus
because some apps are accessing the machine id from here (may only containing a symbolic link to the 'real' machine id). And at least you may need the hidden home folder ~/.pulse
for some temp data (i am not sure about this).
docker run -ti --rm \
-v /dev/shm:/dev/shm \
-v /etc/machine-id:/etc/machine-id \
-v /run/user/$uid/pulse:/run/user/$uid/pulse \
-v /var/lib/dbus:/var/lib/dbus \
-v ~/.pulse:/home/$dockerUsername/.pulse \
myContainer sh -c "echo run something"
当然,你可以结合在一起既与的Xserver
UI转发喜欢这里一起使用它:http://stackoverflow.com/a/28971413/2835523
Of course you can combine both together and use it together with xServer
ui forwarding like here: http://stackoverflow.com/a/28971413/2835523
仅举:
- 您可以处理其中的大部分(所有没有使用的ID)的
dockerfile
- 使用
的uid = $(ID -u)
来获取用户的ID和GID与ID -g
- 具有此ID创建一个泊坞窗的用户
- you can handle most of this (all without the used id) in the
dockerfile
- using
uid=$(id -u)
to get the user id and gid withid -g
- creating a docker user with this id
创建用户脚本:
mkdir -p /home/$dockerUsername && \
echo "$dockerUsername:x:${uid}:${gid}:$dockerUsername,,,:/home/$dockerUsername:/bin/bash" >> /etc/passwd && \
echo "$dockerUsername:x:${uid}:" >> /etc/group && \
mkdir /etc/sudoers.d && \
echo "$dockerUsername ALL=(ALL) NOPASSWD: ALL" > /etc/sudoers.d/$dockerUsername && \
chmod 0440 /etc/sudoers.d/$dockerUsername && \
chown ${uid}:${gid} -R /home/$dockerUsername
