Wido den Hollander closed CLOUDSTACK-1146.
------------------------------------------
Resolution: Won't Fix
I think we are not going this route. We let the package managers handle the
updates.
Closing this issue for now as it seems to be unused.
> auto update of KVM agent
> ------------------------
>
> Key: CLOUDSTACK-1146
> URL: https://issues.apache.org/jira/browse/CLOUDSTACK-1146
> Project: CloudStack
> Issue Type: New Feature
> Security Level: Public(Anyone can view this level - this is the
> default.)
> Components: KVM
> Affects Versions: 4.0.0
> Reporter: Kevin Kluge
>
> I'd like to see a feature to have the KVM agent automatically updated.
> Managing hundreds or thousands of hosts becomes unwieldy in the current
> design. Chef/Puppet can help but I think it'd be helpful to manage the
> update through CloudStack.
> From an earlier mail on this topic:
> >
> > - In connection to management server, the version of the software is
> > exchanged.
> > - Management server decides that it needs to be downloaded and terminates
> > the connection with a response that contains the url to the new package.
> > - The agent downloads the package using wget and quits.
> > - The script that restarts the agent explodes the package and restarts the
> > agent.
> > - The agent connects again with the matched version.
> I'd want this to have some way for the admin to control the update. The use
> case is to slowly roll out the change across the hosts, or roll it out to
> just a few clusters/pods first, verify functionality, then roll it out to all
> hosts. Maybe unmanage hosts/clusters is sufficient for this.
> We also need to think through host OS upgrade. Suppose a version of
> CloudStack no longer supports RHEL 6.x for example. Now the admin needs to
> update RHEL then CloudStack. So it would be nice if the MS could recognize
> that the RHEL version has changed, then download the "new " version of the
> agent (it's actually the same version of CloudStack agent, but built for RHEL
> 7.x for example), then the admin upgrades CS Management Server, then the new
> version of CS agent for RHEL 7.x is downloaded.
