Base Images

Why base images?

Docker offers revolutiony platform to build, ship containerized images. The official images may not match our requirements for packaging modules. So, our base images are design according to following reasons:

Base images provide minimum requirements for specific usage. For example, zetdata/cdh:4 are base images for CDH4 hadoop cluster. And zetdata/sci-python:2.7 can provide scikit-learn toolkit for python data scientists.

Can also save bandwith. Of course, you can build your own module from scratch. Docker offers incremental pulling, which will pull differental images from remote registry server. So, it may save bandwith and time if we share same base images.

All scripts to build base images are released at github repo, and images are pushed to official docker registry.
