Bicep - create credentials for Managed Identity for use in LinkedService - azure

Question

I am attempting to re-create an Azure Data Factory using Bicep, and specifically i am trying to user a User Assigned Managed Identity for a linked service to an Azure SQL Database.
I am able to create the ua MI by doing the following -
resource uami 'Microsoft.ManagedIdentity/userAssignedIdentities#2018-11-30' = {
name: uamiName
location: location
}
This gets successfully attached to the data factory upon build.
Next i am trying to associate that UA MI to the database connection i am making in the Linked Services section. In the front end its like selected 'User Assigned Managed Identity' and selecting the creds ( or create new). I am trying to do this via Bicep and In order to do this, i first needs credentials - I can't find anywhere in Bicep to create these credentials.
I see lots of old references to Microsoft.DataFactory/factories/credentials - but i can't seem to find that.
Appreciate any help that anyone can offer.

Answer 1

I haven't found much documentation neither.
I've created a credential from data factory studio then export the ARM template. The bicep equivalent looks like that:
param location string
param uamiName string
param dataFactoryName string
// Create the managed identity
resource uami 'Microsoft.ManagedIdentity/userAssignedIdentities#2022-01-31-preview' = {
name: uamiName
location: location
}
// assuming the data factory already exists
resource dataFactory 'Microsoft.DataFactory/factories#2018-06-01' existing = {
name: dataFactoryName
}
// Create the credentials
resource credentials 'Microsoft.DataFactory/factories/credentials#2018-06-01' = {
name: uami.name
parent: dataFactory
properties: {
type: 'ManagedIdentity'
typeProperties: {
resourceId: uami.id
}
}
}
