Upgrade Router via API after CP Upgrade

Hi all,

we are currently planning an update of CP, which also includes an upgrade of the System VMs. We are upgrading from 4.5 to 4.7.

I wrote a python script to check VPN connections and other parameters. Some upgrades can be performed right after the CP upgrade, some other routers must not be upgraded, as those will be upgraded manually after some more coordination.

Now I am struggling how to upgrade the Routers using the API. I found the command “upgradeRouterTemplate“ (https://cloudstack.apache.org/api/apidocs-4.5/root_admin/upgradeRouterTemplate.html), which, when I understand it correctly, should support that. However, when upgrading using the GUI I can select both the SystemVM Template and opt to use a shadow mode. The command mentioned above however does not allow me to specify those arguments.

So my question is: what would be the best way to upgrade the routers using the API?

Thanks and regards
Daniel

Re: Upgrade Router via API after CP Upgrade

Hi Dag,

aah, the global setting was the missing piece in the puzzle, that makes total sense now. Thank you. I am currently using the Python CS module for coding the script, I will use that for the task at hand.

And yes, you are right, this is actually CloudPlatform. We are currently at 4.5 and the upgrade to 4.7(.1) includes some major changes regarding the S2S VPN, the update is quite complicated and required detailed planning and coordination with our customers while upgrading the VPRs. I was not aware that this specific feature (shadow mode) is CP only, which however explains why I could not find any hint in the API documentation.

Regards
Daniel

Hi Daniel,

In general your VR template is governed by the global setting for router.template.vmware (or whatever your hypervisor is) – this field is updated when you do your upgrade, so ACS knows what the new template is.

To do the upgrade your easiest option is to use CloudMonkey and call the upgradeVirtualrouterTemplate API call from command line. Something like “cloudmonkey upgrade virtualroutertemplate account=XYZ zoneid=aa-bb-cc-dd podid=aa-bb-cc-dd id=123123” etc should do it – refer to the API documentation page you have found. As always though I would recommend testing this beforehand in a non-prod environment.

With regards to your GUI options – are you using CloudStack or CloudPlatform? (The shadow mode is not a feature of Apache CloudStack at this point).
