Docker and IPv6

See: https://docs.docker.com/v17.09/engine/userguide/networking/default_network/ipv6/#how-ipv6-works-on-docker#

Docker-compose an IPv6

See https://collabnix.com/enabling-ipv6-functionality-for-docker-and-docker-compose/

Please note: version: "2.4" works fine but 3.x not - see https://docs.docker.com/compose/compose-file/
... and the following not (2019-12-21):```

If IPv6 addressing is desired, the enable_ipv6 option must be set,

...

 
and you must use a version 2.x Compose file.

...

 
IPv6 options do not currently work in swarm mode.
