--------------------------------------------
Summary: Add Template Refresh Option
Key: CLOUDSTACK-7921
URL: https://issues.apache.org/jira/browse/CLOUDSTACK-7921
Project: CloudStack
Issue Type: Improvement
Security Level: Public (Anyone can view this level - this is the default.)
Components: Management Server
Affects Versions: 4.4.0
Reporter: Michael Phillips
I. Proposal
I would like to propose a new function in which we have the ability to refresh
a template. OS templates need to be refreshed every so often to update things
like OS patches and software.
II. Current Method
Currently the only way to refresh a template is to delete the old template,
then upload the new template.
III. The issue
There are 3rd party apps out there, such as hostbill, that use cloudstack for
vm provisioning. When a template is created it seems the template gets assigned
a unique GUID in the database. When you refresh the template by deleting and
re-uploading, the new template has a new GUID which breaks any connections to
the old template.
IV. How to possibly solve
Have a new function to refresh a template. Refreshing the template would reuse
all the info from the old template, but would just replace the templates disk
file with the new one.
