Create a VM Template

Although Palette provides out-of-the box templates, we recommend that you create and manage your own templates.

Prerequisites

Valid YAML that defines your VM template.

Create a VM Template

Create a template by adding a YAML file as a manifest in an add-on profile.

Log in to Palette.
From the left Main Menu, click Profiles and click the Add Cluster Profile button.
Give the profile a name, select type Add-on, and click Next.
On the Profile Layers page, click Add Manifest.
Give the layer a name, and click Edit manifest and enter a name for the first template. Click the checkmark icon.
In the blank manifest file at right, enter the VM definition as a YAML file. You can add multiple manifests for multiple templates in the same add-on profile. They will display as layers in the profile.
Click Confirm and Create, then click Next.

Click Finish Configuration.
