This article describes a way to insert an appliance that is likely to be instanciated on different clouds.
LAL Marketplace is available here: MarketPlace. It presents a repository if appliances usable on the cloud.
In its current version, the Marketplace permits to define an appliance that can be launched in a single click over a set of cloud thanks to a simple description file manipulation.
Step 1
Insert the appliance in one or more clouds.
Step 2:
Use Stratuslab scripts to create the appliance metadata.
$> stratus-build-metadata \ --author="John Doe" --os=SL --os-version=6.6 --os-arch=x86_64 \ --image-version=1.0 \ --comment="cernvm 3.5.1 (http://cernvm.cern.ch)" \ --format=raw \ --hypervisor=kvm \ --title=cernvm3.5.1 \ --location=http://cernvm.cern.ch/releases/production/cernvm-3.5.1.hdd \ cernvm-3.5.1.hdd
This tool creates the SL-6.6-x86_64-base-1.0.xml description file.
Step 3
The description file must be modified by hand. You must add as many locations as clouds where this appliance has been registered.
4th and last step
Use Stratuslab scripts to sign and upload the metadata on the Marketplace.
$> stratus-sign-metadata SL-6.6-x86_64-base-1.0.xml
$> stratus-upload-metadata SL-6.6-x86_64-base-1.0.xmlConclusion
