Install/Update Templates

The Template server URL has to be set at Control panel > Settings > Configuration > Backups/templates tab as a prerequisite for installing/upgrading templates.

VMware vCenter templates are not installed using the template server. For information on installing VMware templates, refer to the VMware Template Installation Guide section.

OnApp template manager allows you to update the system templates which are already installed to your cloud and download new templates available on a template server.

The OnApp template library includes over 100 VS templates based on various 32-bit and 64-bit flavours of Windows and Linux operating systems. OnApp customers can also access a large number of JumpBox virtual Compute resources and deploy them as templates in OnApp. 

Only customers with a Paid license have access to the complete template library, and special deals with JumpBox.

Where templates are stored

Depending on the configuration of your cloud, new templates are stored at different locations.

No backup servers and ssh_file_transfer option is disabled

In this configuration, the templates will be uploaded to all Compute resources. If this template already exists somewhere, the action is skipped. In such case NFS or any other sharing service should be enabled between Compute resource's.

No backup servers and ssh_file_transfer option  is enabled

The template is uploaded to this ssh_file_transfer server only.

There are backup servers and ssh_file_transfer option is disabled

The templates are uploaded to all backup servers. The action is skipped if such a template already exists. In this configuration ensure that some sharing service is between backup servers. Provisioning is performed at backup servers only. If there is more than one backup server in the cloud, the user is prompted to choose to which BS a template will be stored.

There are backup servers and ssh_file_transfer is enabled

The templates are uploaded to this ssh_file_fransfer server only. 

High Availability is configured for the Cloud

In this configuration, make sure to store templates at Database&Transactions server or any other server with shared NFS service, so that both Control Panels could access the templates directory.
