Contextualisation Update
-
Ulrich explained (see presentation) that our current contextualisation proposal is not obciously compatible with OpenStack, Eucalyptus and ISF as they cannot easily mount a CD image. Additionally, this contextualisation method is not compatible with public clouds, such as Amazon, that expect images to contact a dedicated IP address to download contextualisation information.
-
Ulrich thus proposed a modified system that would first try to access contextualisation scripts from a CD image and then, if this failed, use the Amazon compatible system. Imags would, however, be required to execute the HEPiX specific contextualisation mechanism before any contextualisation script suitable for use in a public cloud. This would ensure that any unwanted contextualisation could be prevented by sites.
-
The proposal was well liked and Ulrich and Tomasz were encouraged to return with a proposal for the user data fields and the implementation of the HEPiX plugin. Tomas thought that this should be possible for the next working group meeting.
-
Ulrich highlighted the need to discuss wider distribution of the amiconfig tool with its authors. He felt this ought to be possible given the current licence terms, but some packaging work would be needed before this could be made available in EPEL, say.
-
Progress on image cataloguing
-
Belmiro reported that there has been little progress on the VMIC recently as a key person in the work is now back at ASGC. It is hoped that she will be able to return to CERN in the new year.
-
Michel reported that there has been some testing of StratusLab at LAL but no more detailed tests of the marketplace, nor of the ability of sites to restrict which images can be instantiated.
-
The rather limited doodle registration for the working day on December 7th was noted. It was agreed taht we should postpone this unless more people signed up.
