请教各位前辈一个 docker 容器分配 ipv6 地址的问题

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.
