问题
我全新安装了 Fedora 27。我在上面安装了 docker-ce-17.12.0 。
现在，如果我尝试启动一个如下所示的容器：
docker run -d -p 10.1.1.56:80:8080 --restart always --volume /docker/magic_mirror/config:/opt/magic_mirror/config --volume /docker/magic_mirror/modules:/opt/magic_mirror/modules --name magic_mirror bastilimbach/docker-magicmirror
如果我查看防火墙，我会看到以下错误：
● firewalld.service - firewalld - dynamic firewall daemon
