That is not very clear from the docs then which say "By default, the Docker server configures the container network for IPv4 only. You can enable IPv4/IPv6 dualstack support by running the Docker daemon with the --ipv6 flag" - that doesnt sound like link local addresses by default...

Will have to take a look, I guess there are lots of potential setups. If you have a /64 per host it should be ok anyway, if you have a /64 for the network it might not be.

Link local addresses are not meant for application level use in IPv6 so bringing them up would only be confusing.

LL addresses are used for stuff like router advertisement, neighbour discovery (IPv6 equivalent of ARP) etc. You can't use link-local addresses without extra gyrations in socket API (scope id) so they cannot be usefully passed to normal apps.
