我在从仅IPv6主机上的Docker(版本1.5.0)容器路由流量时遇到问题. nc -w 10 2a00:1450:4010:c07 :: 71 80输出nc:连接到2a00:1450:4010:c07 :: 71端口80(tcp)超时:操作正在进行中.
遵循this documentation ifconfig eth0; ifconfig docker0; ip -6 route show显示:

启用IPv6和IPv4路由(cat / proc / sys / net / ipv6 / conf / default / forwarding为1,cat / proc / sys / net / ipv6 / conf / all / forwarding为1).
好像我需要添加从docker0桥接IPv6流量到eth0的路由,但不知道究竟要做什么.
请停下来!
最佳答案
不推荐在IPv6环境中进行任何类型的NAT,这违背了IPv6的目的.
您可以使用管道工程通过IPv6完成对容器的访问.
Pipework允许更灵活的网络配置:
sudo docker run -t -i --name myimage
为了能够从Internet访问您的容器,您需要从公共IPv6的子网分配IPv6地址.
通过将IPv6地址分配给容器(eth1)中的新接口,将删除IPv4默认路由,并且新的IPv6默认路由将通过eth1指向新的IPv6默认网关.
应用管道之前的容器接口:
root@a0b5f4937c42:/# ip a
1: lo:
容器接口应用管道后:(eth1)
root@9c8372c70ddc:/# ip a
1: lo:
从容器到docker主机::
