網路 - Docker for Mac 容器IP設定問題

Question

1. 宿主機Mac相關資訊

   en0: inet 192.168.2.117 netmask 0xffffff00 broadcast 192.168.2.255

2. Docker for Mac 相關資訊

   # ip addr show eth0
   4: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000
       link/ether c0:ff:ee:c0:ff:ee brd ff:ff:ff:ff:ff:ff
       inet 192.168.65.2/29 brd 192.168.65.7 scope global eth0

3. 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

4. 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
           inet6 fe80::42:c0ff:fea8:282  prefixlen 64  scopeid 0x20<link>
           ether 02:42:c0:a8:02:82  txqueuelen 0  (Ethernet)
           RX packets 0  bytes 0 (0.0 B)
           RX errors 0  dropped 0  overruns 0  frame 0
           TX packets 9  bytes 718 (718.0 B)
           TX errors 0  dropped 0 overruns 0  carrier 0  collisions 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。 。 。
