环境centos7.8

docker容器使用systemctl命令报错:

[root@d7a74069b83c yum.repos.d]# systemctl status firewalld
System has not been booted with systemd as init system (PID 1). Can't operate.
Failed to connect to bus: Host is down

solution:

启动容器时加入参数 --privileged

[root@localhost ~]# docker run -itd --name c8 --privileged centos /usr/sbin/init

[root@localhost ~]# docker exec -it c8 /bin/bash
