//=== On ubuntu_x64 on hyperV,
when using the binary docker downloaded by
$ wget https://get.docker.com/builds/Linux/x86_64/docker-latest -O docker
$ chmod +x docker
[ http://it.3hd.me/2015/03/docker-install-by-binary.html ]


$ ~/docker ps
FATA[0000] Get http:///var/run/docker.sock/v1.17/containers/json:
dial unix /var/run/docker.sock: no such file or directory.
Are you trying to connect to a TLS-enabled daemon without TLS?

-->
$ sudo ~/docker -d &
$ ~/docker ps
$ ~/docker pull username/img:tag

* docker acts both as server and client.
$ docker version
is command internal to the docker executable and not to the daemon/service running.

$ docker images
$ docker ps
$ docker pull centos
are commands which send queries to the docker daemon/service running.


* Docker by default supports TLS connection to its daemon/service.

[Q] when is TLS connectivity not required?
Only if the user you are logged in as is part of user group docker
or you have used sudo before the command
e.g. $ sudo docker images does not require TLS connectivity.

*** steps to install docker on ubuntu on hyperv :
[use the lxc-docker package for ubuntu from docker.io]

$ sudo apt-get update

Upgrade the components (aka patch the OS)
$ sudo apt-get upgrade -y

Add Docker gpg key (that is 'qO' not 'qZero')
$ sudo sh -c "wget -qO- https://get.docker.io/gpg | apt-key add -"

Update the app list
$ sudo sh -c "echo deb http://get.docker.io/ubuntu docker main\ >> /etc/apt/sources.list.d/docker.list"

Update the local apt repository after adding the docker reference
$ sudo apt-get update

Install (latest) Docker (on 12/15/14 this is 1.4.0)
$ sudo apt-get install lxc-docker -y

$ docker version
$ docker pull username/imgname:tagname

$ ps aux| grep docker

--> service name is docker rather than "docker.io"
$ sudo service docker stop
$ sudo service docker start
