Docker容器中使用systemctl报错
当在Dokcer容器中使用systemctl
时报以下错误
System has not been booted with systemd as init system (PID 1). Can't operate.
Failed to connect to bus: Host is down'
问题原因:
启动容器时执行的启动是/bin/bash
,没有相应的权限调用内核程序,需要在run
修改相应的指令获得权限
解决办法
在run
指令后加--privileged=true,修改/bin/bash
为/sbin/init
docker run --privileged=true -itd xxxxx /sbin/init
进入容器时使用的是docker exec -it xxxxx /bin/bash
