如何从docker集装箱访问ipv6主机？
在我的主机上，ipv6正在工作：
bessarabov@5:~$ curl --silent --verbose ipv6.google.com 2>&1 | head * Rebuilt URL to: ipv6.google.com/ * Trying 2a00:1450:4010:c04::71... * Connected to ipv6.google.com (2a00:1450:4010:c04::71) port 80 (#0) > GET / HTTP/1.1 > Host: ipv6.google.com > User-Agent: curl/7.43.0 > Accept: */* > < HTTP/1.1 200 OK < Date: Mon, 01 Feb 2016 08:44:04 GMT 但是在docker里面没有ipv6：
$ docker run --rm -it ubuntu:14.04.3 bash root@54c52afa87ee:/# ifconfig eth0 Link encap:Ethernet HWaddr 02:42:ac:11:00:02 inet addr:172.17.0.2 Bcast:0.0.0.0 Mask:255.255.0.0 inet6 addr: fe80::42:acff:fe11:2/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:8 errors:0 dropped:0 overruns:0 frame:0 TX packets:8 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:648 (648.0 B) TX bytes:648 (648.0 B) lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:65536 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:0 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:0 (0.0 B) TX bytes:0 (0.0 B) root@54c52afa87ee:/# apt-get install -y curl ... root@54c52afa87ee:/# curl --silent --verbose ipv6.google.com 2>&1 | head * Rebuilt URL to: ipv6.google.com/ * Hostname was NOT found in DNS cache * Trying 2a00:1450:4010:c04::71... * Immediate connect fail for 2a00:1450:4010:c04::71: Network is unreachable * Closing connection 0 root@54c52afa87ee:/#
我应该怎么做才能从docker容器访问ipv6主机？
我在我的Mac上使用docker。 我用docker-toolbox安装了它。

从文档
https://docs.docker.com/engine/userguide/networking/default_network/ipv6/
我懂了
默认情况下，Docker服务器仅为IPv4configuration容器networking。 您可以通过运行带有–ipv6标志的Docker守护程序来启用IPv4 / IPv6双栈支持。
你用IPv6启动docker守护进程吗？
