docker systemctl System has not been booted with systemd as init system (PID 1). Can't operate

引用:当使用命令systemctl时，报错信息为"System has not been booted with systemd as init system (PID 1). Can't operate. Failed to connect to bus: Host is down"。
这个错误意味着docker容器内的操作系统没有使用systemd作为初始化系统(PID 1)。在这种情况下，systemctl命令无法正常工作。
解决这个问题的方式是在docker容器内使用一个PID为1的init系统，例如使用supervisord或runit作为init系统。这样就可以正常使用systemctl命令了。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
