业务需求容器需要分配一个 ipv6 地址
目前的我的方法是通过macvlan来分配，创建 macvlan 的代码是：

docker network create -d macvlan      --subnet=10.47.242.0/24      --gateway=10.47.242.1      --subnet=2001:250:6000:10::/64      --gateway=2001:250:6000:10::1      -o parent=em1      -o  macvlan_mode=bridge my_macvlan 

em1 网卡的信息如下：

2: em1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000     link/ether 14:18:77:5c:c3:22 brd ff:ff:ff:ff:ff:ff     inet 10.47.242.191/24 brd 10.47.242.255 scope global noprefixroute em1        valid_lft forever preferred_lft forever     inet 10.47.242.190/24 brd 10.47.242.255 scope global secondary noprefixroute em1        valid_lft forever preferred_lft forever     inet 10.47.242.132/24 scope global secondary em1        valid_lft forever preferred_lft forever     inet6 2001:250:6000:10::a2f:f2bf/64 scope global noprefixroute        valid_lft forever preferred_lft forever     inet6 fe80::bd38:d6df:2161:618c/64 scope link noprefixroute        valid_lft forever preferred_lft forever 

然后创建容器的时候通过ip6参数指定地址：

docker run -itd --privileged --network=my_macvlan --ip=10.47.242.212 --ip6=2001:250:6000:10::12 --name=demo commonimage:v3 /usr/sbin/init 

进入容器查看网卡信息时只显示 v4 地址，不显示 v6 地址：

inet 10.47.242.212/24 scope global eth0 valid_lft forever preferred_lft forever`   inet6 fe80::42:aff:fe2f:f2d4/64 scope link   valid_lft forever preferred_lft forever   

然后查看我创建的 macvlan 的信息，发现其中的EnableIPv6项是false：

        "Name": "my_macvlan",         "Id": "3e65fedeff7a9cfeed65f92588c1d283010c51c827803fc7fec8400b5081e7f6",         "Scope": "local",         "Driver": "macvlan",         "EnableIPv6": false,         "IPAM": {             "Driver": "default",             "Options": {},             "Config": [                 {                     "Subnet": "10.47.242.0/24",                     "Gateway": "10.47.242.1"                 },                 {                     "Subnet": "2001:250:6000:10::/64",                     "Gateway": "2001:250:6000:10::1"                 }             ]         },  

现在就是卡在这里，通过 docker 的官网，百度，修改过 docker 的daemon.json,添加如下配置:

"ipv6": true, "fixed-cidr-v6": "2001:250:6000:10::/64" 

但是仍然不支持 ipv6，请问各位有没有遇到这种需求 /问题，可以指点一下.
