Create Namespace Template
Namespace templates can be created directly in the UI.
- Select the Templates field on the left-most menu bar. 
- From the Templates sub-menu, select the Spaces button. 
- Click button. 
- In the drawer that appears from the right, give your space template a name by replacing the - my-templateplaceholder name, or by updating the manifest YAML- metadata.namefield.
- [Optional] Update the template with any additional desired configuration options. - The Definition tab contains settings relating to the space deployment itself, primarily related to sleeping, see the Sleep Mode section for more details. 
- Objects is where you can define Kubernetes manifests that should be created in the virtual cluster. 
- Apps allows you to select any pre-defined 'applications' (ex: Cert Manager) that should be installed into the virtual cluster. 
- Parameters provides a mechanism for exposing values that users should be able to modify when deploying a virtual cluster from this template. 
- Permissions are additional access rules that can be defined for the virtual cluster instance. 
- Finally, Template Permissions are the permissions that are applied to the template itself -- that is, who has permission to view/edit this template. 
 
- Click on the button at the very bottom.
