You can use the property dictionary to define new custom properties.

You can customize how properties appear in the user interface.

Associate a property name with a user control, such as a check box or drop-down menu.

Specify constraints such as minimum and maximum values or validation against a regular expression.

Provide descriptive display names for properties or add label text.

Group sets of property controls together and specify the order in which they appear.

Use the following workflow when you define and use a custom property definition.


Add a new property and associate it with a property control type.


Add relevant property attributes to the property.

Attributes contain additional information such as minimum and maximum values or help text to display with the property. Available attribute types vary depending on the control type.


Add the properties to a blueprint on the Properties tab on the blueprint form. Alternatively, add the properties to a build profile.

A tenant administrator or business group manager can create or edit blueprints. For information about adding properties to blueprints and build profiles, see the applicable IaaS Configuration guide in vCloud Automation Center 6.1 documentation.


(Optional) Add a control layout to specify where the properties appear on the machine confirmation page.

New custom properties are typically used by custom workflows to specify how to run a command based. You can use vCloud Automation Center Designer to define these custom workflows. For more information about working with custom workflows, see Extension Development.
