The document proposes developing a Yum plugin to handle downloading and installing Docker container images with simple Yum commands. It would create a server-side repository of pre-built images exposed to users. The plugin would implement commands like 'yum list container', 'yum install container', and 'yum erase container' to make accessing images as easy as installing RPMs. The proposal includes a 12-week timeline to develop and test the plugin.

1. Yum plug-in to handle docker /container images
Project Information:
Project Title: Yum plug-in to handle docker /container images
Project Description: A single yum command that can download and install container images.
Containers are going to be big moving into the future as a way to download and run silo'd
instances of applications and services. In this effort, we would setup a serer side repository of
pre-built and pre-configured images that are consumable directly under lxc/docker; we would
then write the yum code needed to expose that repository to the users and a few simple
commands to download and install the images users want. In this effort, we would setup a server
side repository of pre-built and pre-configured images that are consumable directly under
Docker; we would then write the yum code needed to expose that repository to the users and a
few simple commands to download and install the images users want.
Details: The problem space we are trying to address here is that at the moment, there is no way
to easily mass build and promote container images (a problem easily solved in the RPM world
with yum and the server metadata for RPM/yum repositories). Given that the mechanism to
facilitate this already exists in yum, it makes most sense to just consume that interface along with
the backend support, and run it for container images. We need to be able to implement 'yum list
container', 'yum install container', and 'yum erase container'. Due to the nature of how containers
work, we will not need to implement a 'yum upgrade container' command since the instance
would update using its own yum mechanism inside the container.
This extends just delivering dockerfiles in an RPM, it enables existing system management
tooling to work with an evolving container set, by being treated much like an RPM repository
would be.
Benefits: Downloading and installing container images using a single Yum command.
Repositories are created and exposed to the users so that they can download the images using
simple yum commands

2. Implementation: Using the repositories and packages available and creating a server side
repository with pre-built images and these images are written into the yum then developing the
yum code which would be useful in exposing the repository to the user, implementing yum list
container, yum install container, yum erase container. The simple yum commands are developed
and given to the user so as to make the download and installation of images simple.
Timeline:
Week 1: 19th may to 25th may - A better understanding of package management in linux of
various distributions
Week 2: 26th may to 31st may - creating a server side repository and adding pre built
images to the container.
Week 3: 1st June to 7th June – creating and implementing yum list container.
Week 4: 8th June to 14th June – creating and implementing yum install container.
Week 5: 15th June to 21st June – creating and implementing yum erase container.
Week 6: 22nd June to 28th June – checking the serverMeta data for rpm/yum repositories.
Week 7: 29th June to 5th July – Understanding the nature and working of the container.
Week 8: 6th July to 18th July – Developing the code for yum download and installation.
Week 9: 19th July to 25th july – Testing the code for yum download and installation.
Week 10: 26th July to 2nd Aug – reviewing the code and modifications to be done if any.
Week 11: 3rd Aug to 9th Aug – preparing a manual documentation of the project.
Week 12: 10th Aug to 17th Aug –preparing screen shots of the work done, presentations,
documentations in the guidance of mentors.

 Why Cent OS: With the support and help of GSOC 2015, I want to stick to Cent OS
projects where I can contribute my skills of linux,python and openstack into the projects
and develop a effective module that benefits to the organization and also benefits in
gaining and sharing knowledge which would be an exciting and interesting journey. It
