Default Image ID

[Barak Merimovich <ba...@gmail.com>]

Hi,



I've noticed that when starting a machine without providing jclouds with an
imageId, I get some default image.

in amazon for instance, the default image used is 'ami-99df3ff0'.

I was wondering how you choose these images and whether I can count on
these images to always be available.

My objective is to not be dependent on a specific amazon image ID (or any
other cloud image) for that matter, and to always have a working image id,
since I've noticed image ids tend to change or get deprecated.

Thanks,

Barak

Assuming you are creating images using  
ComputeService.createNodesInGroup [1], the image is chosen based on  
the TemplateOptions provided. If you don't provide them, the default  
set will be used, which can usually be found in the provider's  
metadata, e.g. [2].

Hope this helps!
