使用 Bicep 在 Azure Blob 存储容器上添加 RBAC 角色

我正在使用 bicep 部署 azure data Lake gen2 存储帐户。 我想在带有二头肌的容器上分配角色（组）（参见下面的代码）。但我不断收到错误。有人能帮我吗 ？

targetScope = 'resourceGroup' 

param location string =resourceGroup().location
param storageAccountName string

resource stg 'Microsoft.Storage/storageAccounts@2021-04-01' = {
  name: storageAccountName
  location: location
  sku: {
    name: 'Standard_LRS'
  }
  kind: 'StorageV2'
  properties: {
    isHnsEnabled: true
  }
}

resource bs 'Microsoft.Storage/storageAccounts/blobServices@2021-08-01' = {
  name: 'default'
  parent: stg
}


resource container 'Microsoft.Storage/storageAccounts/blobServices/containers@2021-08-01' = {
  name: 'help'
  parent: bs
}

resource rbac  'Microsoft.Authorization/roleAssignments@2020-10-01-preview' = {
  name: guid(container.id,'xxx')
  scope: container
  properties: {
    principalId: 'xxx'
    principalType: 'Group'
    roleDefinitionId: '2a2b9908-6ea1-4ae2-8e65-a410df84e7d1'
  }
}

Error:

{"status":"Failed","error":{"code":"DeploymentFailed","message":"At least one resource deployment operation failed. Please list deployment operations for details. Please see https://aka.ms/DeployOperations for usage details.","details":[{"code":"BadRequest","message":"{\r\n  \"error\": {\r\n    \"code\": \"BadRequestFormat\",\r\n    \"message\": \"The request was incorrectly formatted.\"\r\n  }\r\n}"}]}}

根据document https://learn.microsoft.com/en-us/azure/templates/microsoft.authorization/roleassignments?tabs=bicep您应该添加一个条件，但这也不起作用。

condition: '@Resource[Microsoft.Storage/storageAccounts/blobServices/containers:ContainerName] StringEqualsIgnoreCase \'help\''

The roleDefinitionIdproperty 是角色的资源标识符。它也是订阅级资源，因此您可以在二头肌文件中定义它，如下所示：

roleDefinitionId: subscriptionResourceId('Microsoft.Authorization/roleDefinitions', '2a2b9908-6ea1-4ae2-8e65-a410df84e7d1')
