docker 无法执行systemctl:System has not been booted with systemd as init system (PID 1). Can't operate. Failed to connect to bus: Host is down

背景

System has not been booted with systemd as init system (PID 1). Can't operate. Failed to connect to bus: Host is down

解决办法

运行容器的时候加上参数--privileged 并且使用/usr/sbin/init 或者/sbin/init ,不要使用/bin/bash
例如debian系列（ubuntu、uos、deepin）
docker run -itd --privileged=true 容器id /sbin/init
例如redhat系列（centos）
docker run -itd --privileged=true 容器id /usr/sbin/init

进入容器依旧使用 /bin/bash
