Azure Roles

There are a lot of role GUIDs to remember or lookup.

Make it easier on yourself.

Important

The azure_roles.json is automatically evaluated daily for new roles and updated when new roles are discovered.

Simplify using Azure's built-in roles in Bicep and Terraform

How to

Copy the "azure_roles.json" file from this repo
Make it available in your repo
Use the following example to leverage the JSON to make it easier when assigning Azure's built-in roles.
Lookup the role in the json, now you can use plain english in the bicep file to always know the role being assigned
1. FYI, you can use Visual Studio Code's auto-complete feature when enumerating the azureRoles var instead of looking it up in the json.

Example

Bicep

// From main.bicep

// Parameters
param principalId string = ''
param principalType string = 'User'

// Variables
// Use Bicep's loadJsonContent to use Azure Roles JSON
var azureRoles = loadJsonContent('azure_roles.json')

// Resources
// Role assignment
resource openAiRoleUser 'Microsoft.Authorization/roleAssignments@2022-04-01' = {
  name: guid(subscription().id, resourceGroup().id, principalId, roleDefinitionId)
  properties: {
    principalId: principalId
    principalType: principalType
    roleDefinitionId: azureRoles.CognitiveServicesOpenAIUser
  }
}

Terraform

locals {
    # Use Terraform's jsondecode to use Azure Roles JSON
    azure_roles = jsondecode(file("${path.module}/azure_roles.json"))
}

data "azurerm_subscription" "primary" {
}

data "azurerm_client_config" "example" {
}
    
resource "azurerm_role_assignment" "example" {
  scope                = data.azurerm_subscription.primary.id
  role_definition_id   = local.azure_roles.CognitiveServicesOpenAIUser
  principal_id         = data.azurerm_client_config.example.object_id
}

Use Case

Enumerating in VS Code

You can autocomplete in line in VS code.

Inline Search in VS Code

Beyond enumerating, you can search inline to find the appropriate role.

Inline GUID Review

Hovering over the role will provide the GUID. Helpful if you are translating existing GUID into the JSON variable.

Searching for role in JSON

You can always search through the JSON. Helpful if you are translating existing GUID into the JSON variable.

Updating Azure Roles JSON

New built-in roles are frequently added, to efficiently include these roles - there are two GitHub Actions. One is a manual execution and the other is a scheduled action that runs daily at midnight. The actions run the same PowerShell script, create-azurejson.ps1.

The actions collect secrets from GitHub and save them as environment variables for the script to leverage for authenticating to Azure.

The script collects the latest roles and compares them with the current json. If new roles exist, then the json is committed to the repo with the number of new roles in the message.
