问题描述
我正在尝试通过docker java应用程序控制蓝牙交互。我已经使用了com.github.hypfvieh.bluetooth库，它的工作原理很像。但是，一旦我在docker中运行此应用程序，便无法与系统DBus进行交互。我达到的最佳状态是使用此命令行运行容器
podman run --rm -it --privileged -v /var/run/dbus/system_bus_socket:/var/run/dbus/system_bus_socket --name NAME IMAGE
似乎我可以联系DBus，但是authentication被拒绝了。

Dockerfile看起来像这样：
FROM IMAGE:latest
COPY target/dependency-jars/ /app/dependency-jars/
COPY target/run.jar /app
WORKDIR /app
CMD [ "/bin/sh","run.sh" ]
我试图像这样在docker文件中添加用户
RUN groupadd -g 1000 yves
RUN useradd -u 1000 -g 1000 yves -s /sbin/nologin -d /
USER yves
这无济于事。我还尝试将docker命令-u 1000:1000与localhost用户的uid和gid添加在一起。什么都没有。
所以我不明白为什么身份验证会失败，以及背后的规则是什么，以便根据需要设置容器？
