我正在尝试在运行 Ubuntu 的虚拟服务器上设置基于 docker 的应用程序。该应用程序应该可以使用 IPv6。没问题，我从服务器提供商那里获得了一个 /64 网络，在我启动启用 IPv6 的 docker 网络之前，它运行良好。
一旦网络运行，我的服务器仍然可以从外部通过 IPv6 访问，但我无法从内部通过 IPv6 连接到互联网 - 显然存在路由问题。
我发现问题出在docker0地址为 的默认网桥fe80::1上。不幸的是，默认网关（由我的服务器提供商分配）的地址也是fe80::1，因此一旦网桥联机，就不会再将任何东西路由到互联网。
我整个下午都在尝试让 docker 使用不同的 IPv6 地址作为网桥docker0（我认为这应该可以解决我的问题），但没有成功。--bip中有一个选项dockerd，但不幸的是它只适用于 IPv4，而且没有--bip-v6选项。 我也尝试了--fixed-cidr-v6另一个子网的选项，但这只会为网桥添加一个额外的地址而没有删除fe80::1。
我是不是漏掉了什么？有没有办法为桥接接口使用另一个 IPv6 地址？或者也许有完全不同的解决方案来解决我的问题？
这是我的 IPv6 路由表

答案1
从全新安装开始，你只需告诉 docker 启用 IPv6 并为其提供全局单播 IPv6 子网（/64 或更大）。此子网必须是路由到您现有的 IPv6 主机 IP。
我的实验室的例子：
/etc/docker/daemon.json
{
"ipv6": true,
"fixed-cidr-v6": "2001:470:X:X::/56"
}
并测试它
docker run --rm -it byrnedo/alpine-curl ipv6.icanhazip.com
2001：470：X：X：0：242：ac11：4
你可以有多个具有相同链接本地地址的链接
ip addr | grep "fe80::1"
inet6 fe80::1/64 scope link
inet6 fe80::1/64 scope link
如果以上方法都不适用，或者你的上游无法为你提供额外的子网或路由，并且没有端口冲突，那么只需使用以下命令启动你的应用--net="host"即可（请参阅http://www.debug-all.com/?p=163了解更多信息）。
