Wanted change

I wan't an environment variable to disable IPV6 in nginx.

Reason for change

If you have ipv6 disabled on the host the container won't start because nginx tries to bind to ipv4 and ipv6.

It's possible to bind a nginx configuration file to override this behaviour so it's possible to workaround it although it would be better to set it at container creation via a environment variable.

You can use the unsupported (and thus undocumented) variable DISABLE_IPV6 to disable ipv6
