Big data development environments using Docker

Ferry: Big Data Development Environment using Docker
====================================================

Ferry lets you deploy virtual clusters on your local machine and share your big data application using [Docker](https://www.docker.io). Ferry currently supports:

* Hadoop/YARN (version 2.3.0)
* Cassandra (version 2.0.6) + Titan (0.3.1)
* Spark (version 0.9.1)
* GlusterFS (version 3.4)
* Open MPI (version 1.7.3)

All you have to do to start is specify your stack using YAML or download a pre-existing application.

Why?
====

Ferry is made for developers and data scientists that want to develop big data applications without the fuss of setting up the infrastructure. It will help you:

* Experiment with big data technologies, such as Hadoop or Cassandra without having to learn the intricacies of configuring each software
* Share and evaluate other people's big data application quickly and safely via Dockerfiles
* Develop and test applications locally before being deployed onto an operational cluster

Because Ferry uses Docker underneath, each virtual cluster is completely isolated. That means you can create multiple clusters for different applications.

Getting started
===============

Ferry is a Python application and runs on your local machine. All you have to do to get started is have
`docker` installed and type the following `pip install -U ferry`. More detailed installation instructions and examples can be found [here](http://ferry.opencore.io).


Once installed, you can create your big data application using YAML files.

```yaml
backend:
- storage:
personality: "gluster"
instances: 2
compute:
- personality: "yarn"
instances: 2
connectors:
- personality: "hadoop-client"
name: "control-0"
```

This stack consists of two GlusterFS data nodes, and two Hadoop/YARN compute nodes. There's also an Ubuntu-based
client that automatically connects to those backend components. Of course you can substitute your own
customized client.

To create this stack, just type `ferry start yarn`. Once you create the stack,
you can log in by typing `ferry ssh control-0`.

Contributing
============

Contributions are totally welcome. Here are some suggestions on how to get started:

* Use Ferry, report bugs, and file new features! By filing issues and sharing your experience, you will help improve the software for others.
* Create Dockerfiles for your favorite backend, especially if you think the installation process is harder than it should be. The Dockerfile can be basic and we'll work together to get it ready for other users.
* Create a new configuration module for your backend. This one is more complicated since it will involve actually hacking Ferry, but it's not so hard if we work together.

I strongly recommend using GitHub issues + pull requests for contributions. Tweets sent to @open_core_io are also welcome. Happy hacking!

Under the hood
==============

Ferry leverages some awesome open source projects:

* [Docker](https://www.docker.io) simplifies the management of Linux containers
* [Python](http://www.python.org) programming language
* [Hadoop](http://hadoop.apache.org) is a general-purpose big data storage and processing framework
* [GlusterFS](http://www.gluster.org) is a parallel filesystem actively developed by Redhat
* [OpenMPI](http://www.open-mpi.org) is a scalable MPI implementation focused on modeling & simulation
* [Cassandra](http://cassandra.apache.org) is a highly scalable column store
* [PostgreSQL](http://postgresql.org) is a popular relational database
