Port redirection and IPv6 addresses

[trkoch]

From what I understand, thanks to advanced port redirects it's possible to bind to a specific socket (i.e. IP address + port). If no port is specified all adresses are bound, and from my oberservation this includes all IPv6 interfaces. But how to bind to a single IPv6 address and no IPv4 addresses at all? The spec

[([<host_interface>:[host_port]])|(<host_port>):]<container_port>[/udp]

does not appear to account for colons in the <host_interface>. As a result I'm getting an '�Invalid format to parse.' error from utils.go.

$ docker run -p fd6f:6672:dfac::1ff:fe00:1:22 -t -i /
2014/01/27 17:38:11 Invalid format to parse. fd6f:6672:dfac::1ff:fe00:1:22 should match template ip:hostPort:containerPort

Is it just the port spec parser that is preventing what I'm trying here?

You could bind your docker containers to your ipv6 network and just call them directly instead of through a NAT.

Is this issue still relevant? It's been open for almost a year.

[jessfraz]

it is relevant such that when we add ipv6 support we will most likely close it.

Anything new here? I really could use this feature now. :) I'm currently stuck enhancing docker-proxy and portmapping to get them allowing IPv6. (I also already implemented SNAT and per container set global IPv6 address.)

#8947 has been merged so I believe this can be closed.
You can try it out via the binaries at master.dockerproject.com, and the docs are at http://docs.master.dockerproject.com/articles/networking/#ipv6
