Question

我在不同的PC（相同的Linux版本和相同的Docker版本）上使用相同的图像时发现了一个问题，在Docker中执行service -s时会导致不同的结果。

我正在使用docker attach xx来执行此命令。

在PC 1上正常工作：

service -s 
Checking for udevd:                                                              unused 
Checking for Cron:                                                               unused 
Checking for service D-Bus daemon                                                unused
/etc/init.d/network is disabled, 
can't find any another service enabled as the network.service.
Checking for mounted nfs shares (from /etc/fstab):gssd not running 
idmapd not running
Warning: portmap/rpcbind not running - nfs may not work well
                                                                                unused
Checking for UPS monitoring service                                             unused
                                                                                unused
                                                                                unknown
Checking for service sshd                                                       unused

在PC 2上失败：

service  -s 
Failed to get D-Bus connection: No connection to service manager.

PC 1中输出

以下是我的Dockerfile：

FROM opensuse:13.1
RUN zypper -n install net-tools tar python-xml python rsyslog sudo nfs-client
RUN zypper -n install wget vim less tcpdump aaa_base openssh
RUN zypper -n install syslinux

WORKDIR /root

ENTRYPOINT ["/bin/bash"]

我已经尝试多次在PC 2上重新安装Docker，但它根本没有用完。请帮助我，提前谢谢！

“service -s”无法在Docker容器中运行
