How can I provide suggestions for parameter without enforcing validation in bicep?

I'm developing bicep templates for our developers and wan't to provide suggestion for SKU's.

I'm using a user defined type for this but when doing that the user is enforced to choose one of the values that I declared, I want them able to choose what they want but get the suggestions from my type.

This is what I have:

type Sku = 'P0v3' | 'P1v3'

But I want something like this :

type Sku = 'P0v3' | 'P1v3' | *wildcard*

Is there any way or workaround to achieve that in bicep? Thanks!

Solution

You can use any() function in bicep as a workaround. In your scenario, it can be used to modify user input to Sku type. Sample way is shown below.

type Sku = 'P0v3' | 'P1v3' 
param skuInput string  
var skunew = any(skuInput)

I tried deploying a sample storage account by applying the above function and was deployed successfully as shown.

As an alternative workaround, you can define type Sku = String. Later developers can provide their own values accordingly as detailed in MSDoc.
