Roadmap
- Investigate how to do double endorsement
- Investigate x509 + VOMS authentication
Scope
This workbench deals with the issues around setting up a VM Marketplace to:
- Provide a publicly searchable place for VMs that may provide the application that is needed
- Provide a common place to add a token of endorsement to a pertinent VM
Marketplace Howto
Register an image with the EGI.eu Marketplace

Install and configure stratuslab-cli-tools
This part is very straight-forward, we need stratuslab-cli-tools. So
cd ~ mkdir stratuslab cd stratuslab wget http://repo.stratuslab.eu:8081/content/repositories/centos-6.2-releases/eu/stratuslab/pkgs/stratuslab-cli-user-pkg/2.2/stratuslab-cli-user-pkg-2.2.tar.gz tar xvf stratuslab-cli-user-pkg-2.2.tar.gz
and then conclude the installation process by appending the following to ~/.bashrc
# STRATUSLAB-CLI-TOOLS export PATH=$PATH:~/stratuslab/bin export PYTHONPATH=$PYTHONPATH:~/stratuslab/lib/stratuslab/python
RPMs for the client are also available from the StratusLab yum repositories, see http://yum.stratuslab.eu/. Packages are provided for CentOS 6.2, OpenSuse 12.1 and Fedora 16.
Get demo images
There are two images required for the demo. Each resource provider should upload a metadata entry for each. The first is the BNCweb image, which is available from https://appliance-repo.egi.eu/images/base/egi-bncweb/1.0/egi-bncweb.img. The second is a plain Debian 6 image (https://appliance-repo.egi.eu/images/base/Debian-6.0.5-x86_64-base/1.0/debian-6.0.5-x86_64-base.img).
Upload the image into your cloud
This step is different for every cloud platform. For instance, in OpenNebula v3.4+ you can use Sunstone GUI to upload images directly, in previous versions you have to upload the image to the frontend and then register it.
Sice FedCloud-TF will be using OCCI to access the cloud, you must provide a location of the image that is OCCI-compatible. To find the right link you can browse through all the storage elements registered in your OCCI server
https://occi.host:port/storage/
checking the occi.core.title attribute for the right name. You should end up with something like
https://occi.host:port/storage/a39a1d08-bff8-5a62-ba68-a1cd76bb4511
Build the metadata
The EGI.eu Marketplace stores only metadata which points to the image, provide basic information and integrity verification. Since RDF is not the most user-friendly format, we can use stratus-build-metadata to generate a template
stratus-build-metadata --author='##YOUR_NAME##' --type=base --os=Ubuntu --os-version=11.04 --os-arch=x86_64 \ --image-version=1.0 --hypervisor=xen --format=raw --comment='BNCWeb appliance for the OGF35 demo available at ##YOUR_SITE##' \ --compression=none --location='https://occi.host:port/storage/a39a1d08-bff8-5a62-ba68-a1cd76bb4511' egi-bncweb.img
Note: stratus-build-metadata needs the image to compute checksums, you can download it here egi-bncweb.img
Modify the metadata
Now we can check/modify the metadata, the most important elements are dcterms:valid and dcterms:title.
The correct format for dcterms:title is EGI-##IMAGE_NAME##-##SITE_NAME##. This field will need to be manually added to the metadata file. You can also modify the validity date as required.
Metadata from the EGI.eu Marketplace cannot be removed, it can only expire. It is also possible to deprecate an entry. This might be necessary, if for example, a security issue is detected with the image, or if you simply wish to no longer endorse the image. Instructions for the stratus-deprecate-image command can be found here.

Sign the metadata
To establish the origin of the image, we have to sign the metadata with a personal certificate (ideally the one registered with EGI.eu). Before doing this you should familiarise yourself with the EGI Security Policy for the Endorsement and Operation of Virtual Machine Images.
stratus-sign-metadata --p12-cert=##FULL_PATH_TO_usercred.p12## egi-bncweb.xml
Register the metadata with the EGI.eu Marketplace
And to complete the process, we have to upload the metadata to the EGI.eu Marketplace with stratus-upload-metadata
stratus-upload-metadata --marketplace-endpoint=marketplace.egi.eu egi-bncweb.xml
or manually at
http://marketplace.egi.eu/upload
