Hooray, you have successfully checked out Deltacloud Core. Deltacloud protects yourapps from cloud API changes and incompatibilities, so you can concentrate on managing cloud instances the way you want.
You can find more documentation at the Deltacloud web site at: deltacloud.apache.org/
Deltacloud Core depends on a number of other Ruby libraries. The easiest way to install them is to either install the deltacloud-core package from your distribution is repository, e.g. yum install deltacloud-core on Fedora, or install the gem with gem install deltacloud-core.
If you do not want to do that, have a look at the dependencies in the gem spec for deltacloud-core and install them manually from git repository:
$ git clone git://git.apache.org/deltacloud.git $ cd deltacloud/server $ bundle install
To get started, run ./bin/deltacloudd -i mock; this will run Deltacloud Core with the mock driver, a driver that does not talk to a cloud, but simulates being one. It will store data about its instances etc. in /var/tmp/deltacloud-mock-$USER; that directory will automatically populated with sample data if it does not exist. Subsequent runs will continue using the data found there. If you need to start over from scratch, just delete that directory and restart deltacloudd.
Once you have the server running, point your browser at localhost:3001/api to get a HTML version of Deltacloud Core. If you want to look at the XML that REST clients will see, simply add ?format=xml to URLs. Deltacloud Core does content negotiation; REST clients should not set format to URLs, they should simply set the Accept header appropriately.
Some operations require authentication. For the mock driver, the username and password are mockuser and mockpassword. A current list of drivers and what kind of credentials they need can be found at the Deltacloud site (http://deltacloud.apache.org/drivers.html)
