Docker for Mac 相關資訊

# ip addr show eth0

建立macvlan網路與容器

docker network create -d macvlan --subnet=192.168.2.0/24 --gateway=192.168.2.1  -o parent=eth0 pub_net

docker run --net=pub_net --ip=192.168.2.130 -itd centos /bin/sh

進入容器查看網路資訊

eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 192.168.2.130  netmask 255.255.255.0  broadcast 0.0.0.0

問題：在容器內無法上網，另外broadcast 0.0.0.0這個是不是有問題呢？我的目的是給容器分配一個跟宿主機同網段的IP，跪求解答。 。 。
