请教各位前辈一个 docker 容器分配 ipv6 地址的问题

[ThinkTwive]

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.

--ipv6 你忽略了这个 创建 macvlan 时
