Creating Custom Role in Microsoft Azure

The article explains how to create a custom role for Cloudaware in Microsoft Azure. You need be Owner or User Access Administrator in Microsoft Azure to create custom roles.

1 Create role for Storage Account keys access
2 Create role for tagging
3 Update existing Cloudaware custom policy

Create role for Storage Account keys access

The built-in role "Reader" may not have required permissions, such as default access to the Storage Account keys necessary for collecting data about VHDs.

1. In the Azure portal, select a subscription or a resource group where a custom role should to be assigned.

2. Open 'Access control (IAM)'. Click Add → Add custom role. Name the role Cloudaware Custom Policy.

3. Select one of the following options to proceed:

a) 'Start from scratch'.

Open the tab Permissions → Add permissions. Copy and paste Microsoft.Storage/storageAccounts/listKeys/action in the Search for a permission box to select Microsoft Storage. Check the box near the permission. Click Add.

Click Add.

The permission Microsoft.Storage/storageAccounts/listKeys/action grants 'read' access to Storage Account Keys.

If you are planning to install Breeze Agent, the permission Microsoft.Compute/virtualMachines/extensions/write is required for this custom role as well.

b) 'Start from JSON'.

Use the JSON template below to create a file. Fill your subscription id in the {subscription_id} field.

{
  "IsCustom": true,
  "Name": "CloudAware Collector Extended",
  "Description": "For collecting data about Blob Containers and VHDs we need to get access to the Storage Account keys as the default role Reader does not provide API access to these keys.",
  "Actions": [
    "Microsoft.Compute/virtualMachines/extensions/write",
    "Microsoft.Storage/storageAccounts/listKeys/action"
  ],
  "notActions": [],
  "assignableScopes": [
    "/subscriptions/{subscription_id}"
  ]
}

c) 'Clone a role'. Select one* of the existing roles.

*Commonly used Azure built-in roles:

Built-in Role	ID

Built-in Role	ID
Reader	`acdd72a7-3385-48ef-bd42-f606fba81ae7`
Contributor	`b24988ac-6180-42a0-ab88-20f7382dd24c`
Virtual Machine Contributor	`d73bb868-a0df-4d4d-bd69-98a00b01fccb`
Virtual Network Contributor	`b34d265f-36f7-4a0d-a4d4-e158ca92e90f`
Storage Account Contributor	`86e8f5dc-a6e9-4c67-9d15-de283e8eac25`
Web Plan Contributor	`2cc479cb-7b4d-49a8-b449-8c00fd0f0a4b`
SQL server Contributor	`6d8ee4ec-f05a-4a1d-8b00-a9b17e38b437`
SQL DB Contributor	`9b7fa17d-e63e-47b0-bb0a-15c516ac86ec`

Open the tab 'JSON' to check and modify the permissions (see 3 a) if necessary. The JSON body of the existing role should look like in the template below:

{
  "name": "{your-existing-Role-definition-id}",
  "permissions": [
    {
      "actions": [
        "Microsoft.Compute/virtualMachines/extensions/write",
        "Microsoft.Storage/storageAccounts/listKeys/action"
      ],
      "notActions": []
    }
  ],
  "AssignableScopes": [
    "/subscriptions/{subscription-id}",
     "/subscriptions/{subscription-id}",
    "/subscriptions/{subscription-id}"
  ],
  "RoleName": "{your-Role-name}",
  "RoleType": "CustomRole",
  "type": "Microsoft.Authorization/RoleDefinitions"
}

Replace {your-existing-Role-definition-id} with your role definition id. In the section "AssignableScopes" add the string "/subscriptions/{subscription-id}" with your {subscription-id}.

4. If you add a native application, assign the created custom role to a user. If you add a Web app/API, assign the role to the application.

Creating a custom role in the Azure Portal is an asynchronous process, which means there may be a delay between the role's creation and its availability.

5. Open the tab 'Review + Create'. Check the role details and click Create.

Create role for tagging

Create a custom role to provide Cloudaware with permissions for tagging Azure resources:

"properties": {
        "roleName": "{your-Role-name}",
        "description": "{your-Role-description}",
        "assignableScopes": [
            "/subscriptions/{subscription-id}",
        ],
        "permissions": [
            {
                "actions": [
                    "Microsoft.Resources/subscriptions/tagNames/read",
                    "Microsoft.Resources/subscriptions/tagNames/write",
                    "Microsoft.Resources/subscriptions/tagNames/delete",
                    "Microsoft.Resources/subscriptions/tagNames/tagValues/read",
                    "Microsoft.Resources/subscriptions/tagNames/tagValues/write",
                    "Microsoft.Resources/subscriptions/tagNames/tagValues/delete",
                    "Microsoft.Resources/subscriptions/resourceGroups/read",
                    "Microsoft.Resources/tags/write",
                    "Microsoft.Resources/tags/delete",
                    "Microsoft.Resources/tags/read"
                ],
                "notActions": [],
                "dataActions": [],
                "notDataActions": []
            }
        ]
    }

Replace {your-Role-name}, {your-Role-description} and {subscription-id} with corresponding values from your Azure environment.

Update existing Cloudaware custom policy

Cloudaware may introduce new capabilities that require additional actions and permissions. If a custom role is already in place, it can be updated once across all subscriptions. Cloudaware Technical Account manager will provide the instructions.
