Perform a yum search docker, we can see two docker available:
docker.x86_64 : Automates deployment of containerized applications
docker-io.x86_64 : Automates deployment of containerized applications
Well, at least for today, the docker.x86_64, which is mentioned in , is still 0.11. So please install the docker-io.x86_64, which is 1.0.0-1.el7.
Updated 20140829: there’s more up-to-date repo for docker.
Updated 20150111: it seems the repo is out of managed now. And official repo is upgraded to 1.3.2. Thus the official repo is recommended now.

In python, for cropping image I use PIL. However the dependencies of PIL is huge, also need to install some lib*-dev packages.
So I choose go to crop images:
Usage:
% go run crop.go large.jpeg thumbna
#!/usr/bin/env python
import string
import random
out_file = 'text_file.txt'
file_size = 1024 * 1024
rands = lambda x: ''.join(random.choice(string.letters + string.digits) for x in xrange(x))
with open(out_file, 'w') as f:
f.write(rands(file_size))
