IPv6 on *.docker.io


(Sdstrowes) #1

Hi,

I’m playing through some of the tutorial materials on docs.docker.com. I want deploy docker containers on some of our internal VMs; these VMs are configured with IPv6 access only. I run into trouble very quickly.

For example, let’s go straight to the hello world test:

sds@sds:~/docker/test$ sudo docker run hello-world
Unable to find image 'hello-world:latest' locally
docker: Error response from daemon: Get https://registry-1.docker.io/v2/: dial tcp 52.22.201.61:443: connect: network is unreachable.
See 'docker run --help'.

registry-1.docker.io looks like it has a set of A records that point straight to AWS EC2 hosts. Related, index.docker .io is slightly different: it appears to point to an ELB instance but it also doesn’t have any AAAA records.

Are there any alternative names to point the docker tools at in order to boostrap a docker environment?

I agree IPv6 support is needed, but until it’s implemented you can use a HTTPS proxy or NAT64/DNS64.
