I am creating a template for an environment that spins up multiple VMs. There are quite a few inputs and one of them I wanted was to allow the user to specify a list of users that should have Administrator rights on the VMs. I am using dynamic actions for most of the input fields and that works well for the majority of them. However, it seems that there is no support for making an array of items specified by the user; in my case, this is an array of usernames that the template user can specify.
My ideal solution would be that I can use an array input and whenever the user wants to specify someone to add to the Administrators group they type the name of that individual. An action would query the Active Directory and bring back possible matches to the inserted name. The user can then pick from a list of matches and select the correct one.
A semi-decent mock-up of this can be done in Orchestrator with two input fields, a search bar and an array:
The problem with this is that if you type a new name, it will destroy the list and populate it with other names that now match the new search. Additionally, this isn't even the root problem, as we are talking about the input form in Assembler. Assembler templates don't even have the capability for arrays to take external sources as their values.
How am I to achieve this type of UX with Aria Assembler template input forms? Is this something that is feasible or should I just settle for sending a long string of names in one input parameter? Is it possible for the development team at VMWare to port over the input editor from the Orchestrator workflow editor?
Accepted Solutions
You are using the wrong tool. In Assembler you define the cloud template and its inputs. Think of this as an API definition for your service.
In Service Broker you create Custom Forms, which provides the GUI for your service, this is the presentation layer.
So you need to define your input as Array of Strings in Assembler, then go to Service Broker and create a Custom Form for your published content (cloud template). For an Array of Strings input you have 3 options:
Array Input is the default, with a very basic input list where the user can type:
Multi Select: here you can define a predefined list of options the user can choose from. This list can be static or external source (action based).
And Dual List, with a predefined list of options (static/external):
Having an AD query is not possible as the Cloud Template inputs are limited to primitive types (string, number, boolean and object (properties)). The drawback of the above solutions is that you have to list all the users to select from, and an AD can have too much users to display.
XaaS forms (backed by vRO workflows) can have custom resource types as inputs (AD user, for example) where you could use Value Picker, but this is not available for Cloud Templates. What you can do is create a Resource Action of VMs, as it is similar to XaaS forms and there you can add users in the way you described.
Is it a limited amount of users that could be used. You could use a dual list with a action to fill the left pane and you select the users.
Or do you have search from 100+ users ?
