Hello,

i want to use docker with ipv6.

i install docker and edit the /etc/docker/daemon.json:
{
“ipv6″: true
}

Message:

[root@froodo network-scripts]# systemctl status docker

My ip config:

[root@froodo network-scripts]# ip addr

inet6 fe80::9400:ff:fe17:6a4/64 scope link
valid_lft forever preferred_lft forever

I tried a lot of things from differnt howtos, but only with no success.

What the next steps to running docker with ipv6?

Thx.
