Answer 1

I had the same problem with Ubuntu 12.04 and Docker 1.4.1. Here is my solution:

$ sudo docker push "[host:ip:v6:addr:ess:is:here]:5000/myImage"
FATA[0002] Error: Invalid registry endpoint https://[host:ip:v6:addr:ess:is:here]:5000/v1/: Get https://[host:ip:v6:addr:ess:is:here]:5000/v1/_ping: EOF. If this private registry supports only HTTP or HTTPS with an unknown CA certificate, please add `--insecure-registry [host:ip:v6:addr:ess:is:here]:5000` to the daemon's arguments. In the case of HTTPS, if you have access to the registry's CA certificate, no need for the flag; simply place the CA certificate at /etc/docker/certs.d/[host:ip:v6:addr:ess:is:here]:5000/ca.crt 

So, I have an error.

$ ps axwww | grep /usr/bin/docker
14655 ?        Ssl    2:06 /usr/bin/docker -d
14869 pts/0    S+     0:00 grep /usr/bin/docker

Notice, that there is no extra arguments to /usr/bin/docker.

$ echo 'DOCKER_OPTS="--insecure-registry [host:ip:v6:addr:ess:is:here]:5000"' | sudo tee -a /etc/default/docker
DOCKER_OPTS="--insecure-registry [host:ip:v6:addr:ess:is:here]:5000"
$ sudo service docker restart
docker stop/waiting
docker start/running, process 15615

Let's check if arguments appeared:

$ ps axwww | grep /usr/bin/docker
15615 ?        Ssl    0:00 /usr/bin/docker -d --insecure-registry [host:ip:v6:addr:ess:is:here]:5000
15663 pts/0    S+     0:00 grep /usr/bin/docker

Yes, they do. One more attempt:

$ sudo docker push "[host:ip:v6:addr:ess:is:here]:5000/myImage"
The push refers to a repository [[host:ip:v6:addr:ess:is:here]:5000/myImage] (len: 1)
