Nicolas,

The reason we're considering using the directdownload feature is to
simplify template maintenance/updates. I presume that's what it was
designed for. We want to be able to, preferably through cloudstack
functionality, update the template image file associated with a template.
We planned on achieving this utilizing directdownload to decouple the image
file from the registered template itself when it occurred to us that a
"regrab" button in the template properties webui or an API call to tell
secondary storage to redownload the source would very much simplify this
process.

This brings my questions to:

How difficult would it be to implement something like that?

Is there another way to update the imagefile associated with a template? I
mean, could we manually overwrite the file on secondary storage? Would that
break anything?

What is Cloudstack's recommended best practice for managing template images?


Regards,

Willard (Will)
