moby: get.docker.com is not available from IPv6-only network

As get.docker.com doesn’t have IPv6 address, it’s unreachable from our internal IPv6-only cloud network.

Cloudfront just introduced ipv6 support https://aws.amazon.com/about-aws/whats-new/2016/10/ipv6-support-for-cloudfront-waf-and-s3-transfer-acceleration/

@joegross does tat start to make it feasible?

Hi, do you think it might be possible to try to enable IPv6 support again?

Some other projects also using deb apt to access Amazon CloudFront hosted repositories with IPv6 + TLS seem to have it working for one year now: https://github.com/nodesource/distributions/issues/170 (deb.nodesource.com).

Amazon indeed introduced IPv6 support in CloudFront in October 2016: https://aws.amazon.com/about-aws/whats-new/2016/10/ipv6-support-for-cloudfront-waf-and-s3-transfer-acceleration/ .

@slugan IPv6 support is already available for download.docker.com and I just turned on IPv6 support for get.docker.com and test.docker.com

We have every intention and desire to support IPv6 as soon as it’s practicable. As far as I’m concerned v6 is part of, “being on the internet.”

The reality (as you can see in the comments) is not always straightforward. I promise we’ll have it as soon as we can.
