Cloudkeeper-ONE

OpenNebula backend for Cloudkeeper

What does Cloudkeeper-ONE do?

Cloudkeeper-ONE is able to manage OpenNebula CMF - upload, update and remove images and templates representing EGI AppDB appliances. Cloudkeeper-ONE runs as a server listening for gRPC communication usually from core cloudkeeper component.

Requirements

Ruby >= 2.2.0
Rubygems
OpenNebula >= 5.2 (doesn't have to be present on the same machine)

Installation

From RubyGems.org

To install the most recent stable version

gem install cloudkeeper-one

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

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

Configuration

Create a configuration file for Cloudkeeper-ONE

Configuration file can be read by Cloudkeeper-ONE from these three locations:

~/.cloudkeeper-one/cloudkeeper-one.yml
/etc/cloudkeeper-one/cloudkeeper-one.yml
PATH_TO_GEM_DIR/config/cloudkeeper-one.yml

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

Usage

Cloudkeeper-ONE is run with executable cloudkeeper-one. For further assistance run cloudkeeper-one help sync:

Usage:
  cloudkeeper-one sync --appliances-permissions=APPLIANCES-PERMISSIONS --appliances-tmp-dir=APPLIANCES-TMP-DIR --identifier=IDENTIFIER --listen-address=LISTEN-ADDRESS --opennebula-api-call-timeout=OPENNEBULA-API-CALL-TIMEOUT --opennebula-datastore=OPENNEBULA-DATASTORE
