System Variables
System variables are accessible in both job templates and volume templates. These variables are automatically provided by knot and can be used to dynamically reference information about spaces, templates, users, servers, and more.
To use a system variable, simply specify it in the format ${{ .<group>.<name> }}. For example:
${{ .space.name }}
