IPv6 stack support

Hi,

I’ve enabled IPv6 support by creating /etc/docker/daemon.json with:

{
  "ipv6": true,
  "fixed-cidr-v6": "fd00:0:0:0:17::/80"
}

Upon restart, the docker interface reflects IPv6 support.

docker0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc noqueue state UP group default
link/ether 02:42:da:12:72:54 brd ff:ff:ff:ff:ff:ff
inet 172.17.0.1/16 brd 172.17.255.255 scope global docker0
valid_lft forever preferred_lft forever
inet6 fd00::17:0:0:1/80 scope global
valid_lft forever preferred_lft forever
inet6 fe80::42:daff:fe12:7254/64 scope link
valid_lft forever preferred_lft forever
inet6 fe80::1/64 scope link
valid_lft forever preferred_lft forever

Yet, upon executing a stack, the associated containers (container network) still does not support IPv6.

Is the only option to create the container network manually, followed by joining the containers ?

Hi
pl refer this doc Enable IPv6 support | Docker Documentation and see if it helps

maybe try this GitHub - robbertkl/docker-ipv6nat: Extend Docker with IPv6 NAT, similar to IPv4
