[Fiware-cloud] Flavor metadata in images

[Ezra Silvera]

Also as Alex indicated resources depend on the workload and not just the image. For example, mysql vm may require different memory size depending on the target usage and load

     Alex, the solution there is to include in images info regarding capacity (in terms of CPU, mem, disk and not directly a flavour) and then select the flavours that fit that requirements.
       
       The problem comes when a user tries to launch an image that needs, for instance, 1GB of disk to install the SO using a flavour of 500 MB.

       Hi, 
     
    I'm not sure it is aligned or make sense in terms of OpenStack. The separation between flavors and images was done by design In OpenStack so that you decouple between image and the required resources. I agree it would be nice to show only the flavors that can be used but this should be decoupled from the image (i.e., if you have max 200GB free mem on all hosts don't show flavors with mem > 200MB). 
     
    Note that if we add such link it will need to be maintained through out flavor life cycle (create, delete, etc..) . Also this will require someone who add an image (or someone who define a flavor) to go through ALL images/flavors to validate for these matches. 
     
    
     Thanks

    Hi Kenneth, Alex.  
     
    one the features planned for the Cloud Portal is to, when deploying a VM, only show to the users the flavours that has enough capacity to host the specific image.  
     
    https://jira.fiware.org/browse/CLD-299 
     
    In order to support that, all images should include a metadata field with the info about the flavour they need. I don’t know if it make sense to really support this feature because I’m aware the work load including this field in every images would suppose. 
     
    What do you think?
