EGI AppDB <-> CMF synchronization utility

## What does Cloudkeeper do?
Cloudkeeper is able to read image lists provided by EGI AppDB, parse their content and decide what cloud appliances should be added, updated or removed from managed cloud. During the addition and update Cloudkeeper is able to download an appliance's image and convert it to the format supported by the managed cloud.

Currently supported image formats are:
* QCOW2
* RAW
* VMDK
* OVA

## How does Cloudkeeper work?
Cloudkeeper communicates with cloud specific components via [gRPC](http://www.grpc.io/) communication framework to manage individual clouds.

Currently supported clouds:
* [OpenNebula](https://opennebula.org/) - component [Cloudkeeper-ONE](https://github.com/the-cloudkeeper-project/cloudkeeper-one)
* [OpenStack](https://www.openstack.org/) - component [Cloudkeeper-OS](https://github.com/the-cloudkeeper-project/cloudkeeper-os)
* [Amazon Web Services](https://aws.amazon.com/) - component [Cloudkeeper-AWS](https://github.com/the-cloudkeeper-project/cloudkeeper-aws)

## Requirements
* Ruby >= 2.2.0
* Rubygems
* qemu-img (image conversion utility)
* NGINX (optional)

## Installation

### From RubyGems.org
To install the most recent stable version
```bash
gem install cloudkeeper
```

### From source (dev)
**Installation from source should never be your first choice! Especially, if you are not
familiar with RVM, Bundler, Rake and other dev tools for Ruby!**

**However, if you wish to contribute to our project, this is the right way to start.**

To build and install the bleeding edge version from master

```bash
git clone git://github.com/the-cloudkeeper-project/cloudkeeper.git
cd cloudkeeper
gem install bundler
bundle install
bundle exec rake spec
```

## Configuration
### Create a configuration file for Cloudkeeper
Configuration file can be read by Cloudkeeper from these
three locations:

* `~/.cloudkeeper/cloudkeeper.yml`
* `/etc/cloudkeeper/cloudkeeper.yml`
* `PATH_TO_GEM_DIR/config/cloudkeeper.yml`

The default configuration file can be found at the last location
`PATH_TO_GEM_DIR/config/cloudkeeper.yml`.

## Usage
Cloudkeeper is run with executable `cloudkeeper`. For further assistance run `cloudkeeper help sync`:
```bash
$ cloudkeeper help sync

Usage:
  cloudkeeper sync --backend-endpoint=BACKEND-ENDPOINT --external-tools-execution-timeout=N --formats=one two three --image-dir=IMAGE-DIR --image-list=IMAGE-LIST --qemu-img-binary=QEMU-IMG-BINARY

Options:
