[bug report] pouch pull failed

[elianka]

Issue Description
is pouch pull function fully completed? and is there any doc about pouch usage?
i got failed when using pouch pull.

Describe what happened:

1. i just use pouch pull nginx, and return an error.
   
2. i use the image from alibaba to do pouch pull, also got error.

./pouch pull reg.docker.alibaba-inc.com/busybox:latest

3. i use pouch create to create a container from image. i found that there is no image in "pouch images".

Describe what you expected to happen:

1. i want to got docker images from all kinds of repository.
2. i think pouch should pull images automatically when i use "pouch create ..."
3. also, pouch pull should be worked.

How to reproduce it (as minimally and precisely as possible):

1. ./pouch pull nginx
2. ./pouch pull reg.docker.alibaba-inc.com/busybox:latest

You can use the command " ./pouch pull docker.io/library/nginx:alpine" to pull image. Now, not support "pull nginx".

"reg.docker.alibaba-inc.com" is our internal repo, You can't request it.

got it. maybe should set a default registry in pouch, like moby does.

I think this has been fixed in #266.
Closing this. Feel free to leave a comment if there is more details needed.
