Docker 中的旋钮
Mandos in Docker
我尝试在 Docker 容器中设置 Mandos,但因 dbus 错误而失败。可以 运行 没有 dbus 的服务器,但是 mandos-ctl 和 mandos-monitor 需要 dbus 到 运行.
我的Docker文件
FROM ubuntu:16.04
RUN locale-gen de_DE.UTF-8
ENV TERM=xterm
RUN apt-get update \
&& apt-get install -y mandos \
fping \
dbus \
&& rm -rf /var/lib/apt/lists/*
构建它:docker build -t mandos-server .
如果我挂载 /var/run/dbus
并启动容器:
docker run -v /dev/log:/dev/log -v /var/run/dbus:/var/run/dbus -it mandos-server bash
并开始 mandos --debug
我收到以下错误:

二审:
在不安装 dbus 的情况下启动容器 docker run -v /dev/log:/dev/log -it mandos-server bash
并手动启动 dbus:
/etc/init.d/dbus start
* Starting system message bus dbus [ OK ]
mandos --debug
导致以下错误:

知道出了什么问题吗?也许有解决方案?
该错误消息(在那一行)并不是指 Mandos 对 D-Bus 的使用可以由 mandos-ctl
和 mandos-monitor
控制——它指的是 Mandos 的使用D-Bus 与 Avahi 通信,以要求 Avahi 宣布 Mandos 的 Zeroconf 服务。您可以通过使用 --no-zeroconf
选项、 或 来避免发布 Zercoconf 服务(但请注意 Mandos 客户端默认使用 Zeroconf 来查找服务器),您可以确保Mandos 能够从 Docker 容器内部与 Avahi 通信。
Docker Plex 提供以下说明来解决类似的问题:
Secure method
NOTE: due to some problems inside Plex, it appears not to know it's local IP address inside Docker subnet, avoiding the local discovery to work. If you really want to use this feature, look below for the insecure method.
Avahi daemon is commonly used to help your computers to find the services provided by a server.
Avahi isn't built into this Docker image because, due to Docker's networking limitations, Avahi can't spread it's messages to announce the services out of the Docker virtual network.
If you want to enable this feature, you can install Avahi daemon in your host following this steps (Ubuntu version):
- Install avahi-daemon: run sudo apt-get install avahi-daemon avahi-utils
- Copy the file from avahi/nsswitch.conf to /etc/nsswitch.conf
- Copy the service description file from avahi/plex.service to /etc/avahi/services/plex.service
- Restart Avahi's daemon: sudo /etc/init.d/avahi-daemon restart
But why you need to install this on your host and not in the container? Because if you don't do it this way, the discovery message won't be able to reach your computers.
What will I get with this approach?: The service will be announced on the network, but you will have to login with your account to detect your server. Also, all the streaming you receive is going to be reduced as if you are in an external network.
虽然这可能是正确的想法,但我无法在 Mandos 中找到足够的相似之处来成功完成该过程。特别是,我没有在任何安装目录中找到 mandos.service
(或类似的)。我还会提请注意声明 The service will be announced on the network, but you will have to login with your account to detect your server.
我不清楚这对 Mandos 是否是致命的。
我不知道怎么了...但是我对此 post 的回答被删除了...
