IPv6 not enabled on host breaks the container

[Michael Shadle]

I don't have ipv6 enabled (internal company LAN) and the container instance services all fail.

I know people want ipv6 support, but it shouldn't break those without ipv6. Still trying to see if I can figure out any way around it.

I am not sure i will ever fix this. All docker hosts should be ipv6 capable afaik, so it is much easier to setup at least local ipv6 address than adding unnecessary amount of code which will be handling all daemons configs.

There is one solution though, you can change every failing daemon config by adding customized config to /data/_override/(...absolute path in container). BUT it might break with new versions.

if the host doesn't have it, I don't think the containers do. if it's not easy to do, I guess I will have to look at trying to get the host to have ipv6 and not break something internally.

unRAID doesn't have ipv6 support yet. Here's my fix, if anyone wants to use poste.io with unraid: https://github.com/Starbix/docker-poste.io/blob/master/Dockerfile
