rOCCI-cli - A Ruby OCCI Framework

Requirements

Ruby

• Ruby 1.9.3 or newer is required
• RubyGems have to be installed

Examples

For distros based on Debian:

apt-get install ruby rubygems ruby-dev

ruby -v

Unless you have Ruby >= 1.9.3, please, go to rOCCI-cli#RVM and install RVM with a newer Ruby version.

For distros based on RHEL:

yum install ruby-devel openssl-devel gcc gcc-c++ ruby rubygems

ruby -v

Unless you have Ruby >= 1.9.3, please, go to rOCCI-cli#RVM and install RVM with a newer Ruby version.

To use rOCCI-cli with Java, you need JRE 6 or 7. To build rOCCI-cli for Java, you need JDK 6 or 7.

Installation

From RubyGems.org

Mac OS X has some special requirements for the installation. Detailed information can be found in doc/macosx.md.

To install the most recent stable version

gem install occi-cli

To install the most recent beta version

gem install occi-cli --pre

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/EGI-FCTF/rOCCI-cli.git
cd rOCCI-cli
gem install bundler
bundle install
bundle exec rake test
rake install

From source, for Java

Notice: In order to build rOCCI-cli for Java, you need working jRuby installation. We recommend using rOCCI-cli#RVM.

To build a Java jar file from master use

git clone git://github.com/EGI-FCTF/rOCCI-cli.git
cd rOCCI-cli
gem install bundler
bundle install
warble

For Linux / Mac OS X you can create a OCCI Java executable from the jar file using

sudo echo '#!/usr/bin/java -jar' | cat - occi-cli.jar > occi ; sudo chmod +x occi

RVM

Notice: Follow the RVM installation guide linked below, we recommend using the default 'Single-User installation'.

Warning: NEVER install RVM as root! If you choose the 'Multi-User installation', use a different user account with sudo access instead!

• Installing RVM
• Install Ruby

rvm requirements
rvm install 1.9.3
rvm use 1.9.3 --default

ruby -v

Usage

Client

The OCCI gem includes a client you can use directly from shell with the following auth methods: x509 (with --password, --user-cred and --ca-path), basic (with --username and --password), digest (with --username and --password), none. If you won't set a password using --password, the client will ask for it later on.

To find out more about available options and defaults use

occi --help

To list available resources use

occi --endpoint https://<ENDPOINT>:<PORT>/ --action list --resource compute --auth x509
occi --endpoint https://<ENDPOINT>:<PORT>/ --action list --resource storage --auth x509
occi --endpoint https://<ENDPOINT>:<PORT>/ --action list --resource network --auth x509

To describe available resources use

occi --endpoint https://<ENDPOINT>:<PORT>/ --action describe --resource compute --auth x509
occi --endpoint https://<ENDPOINT>:<PORT>/ --action describe --resource storage --auth x509
occi --endpoint https://<ENDPOINT>:<PORT>/ --action describe --resource network --auth x509

To describe specific resources use

occi --endpoint https://<ENDPOINT>:<PORT>/ --action describe --resource /compute/<OCCI_ID> --auth x509
occi --endpoint https://<ENDPOINT>:<PORT>/ --action describe --resource /storage/<OCCI_ID> --auth x509
occi --endpoint https://<ENDPOINT>:<PORT>/ --action describe --resource /network/<OCCI_ID> --auth x509

To list available OS templates or Resource templates use

occi --endpoint https://<ENDPOINT>:<PORT>/ --action list --resource os_tpl --auth x509
occi --endpoint https://<ENDPOINT>:<PORT>/ --action list --resource resource_tpl --auth x509

To describe a specific OS template or Resource template use

occi --endpoint https://<ENDPOINT>:<PORT>/ --action describe --resource os_tpl#debian6 --auth x509
occi --endpoint https://<ENDPOINT>:<PORT>/ --action describe --resource resource_tpl#small --auth x509

To create a compute resource with mixins use

occi --endpoint https://<ENDPOINT>:<PORT>/ --action create --resource compute --mixin os_tpl#debian6 --mixin resource_tpl#small --attribute occi.core.title="My rOCCI VM" --auth x509

To delete a compute resource use

occi --endpoint https://<ENDPOINT>:<PORT>/ --action delete --resource /compute/<OCCI_ID> --auth x509

Changelog

• Dropped jRuby 1.6.x support
• Updated dependencies

Version 4.0

• added extended support for OCCI-OS
• updated human-readable output rendering
• split the code into rOCCI-core, rOCCI-api and rOCCI-cli
• internal changes, refactoring and some bugfixes

Version 3.1

• added basic OS Keystone support
• added support for PKCS12 credentials for X.509 authN
• updated templates for plain output formatting
• minor client API changes
• several bugfixes

Version 3.0

• many bugfixes
• rewrote Core classes to use metaprogramming techniques
• added VCR cassettes for reliable testing against prerecorded server responses
• several updates to the OCCI Client
• started work on an OCCI Client using AMQP as transport protocol

Version 2.5

• improved OCCI Client
• improved documentation
• several bugfixes

Version 2.4

• Changed OCCI attribute properties from lowercase to first letter uppercase (e.g. type -> Type, default -> Default, ...)

Version 2.3

• OCCI objects are now initialized with a list of attributes instead of a hash. Thus it is easier to check which attributes are expected by a class and helps prevent errors.
• Parsing of a subset of the OVF specification is supported. Further parts of the specification will be covered in future versions of rOCCI.

Version 2.2

• OCCI Client added. The client simplifies the execution of OCCI commands and provides shortcuts for often used steps.

Version 2.1

• Several improvements to the gem structure and code documentation. First rSpec test were added. Readme has been extended to include instructions how the gem can be used.

Version 2.0

• Starting with version 2.0 Florian Feldhaus and Piotr Kasprzak took over the development of the OCCI gem. The codebase was taken from the rOCCI framework and improved to be bundled as a standalone gem.

Version 1.X

• Version 1.X of the OCCI gem has been developed by retr0h and served as a simple way to access the first OpenNebula OCCI implementation.
