Resource functions for Bicep
This article describes the Bicep functions for getting resource values.
To get values from the current deployment, see Deployment value functions.
extensionResourceId
extensionResourceId(resourceId, resourceType, resourceName1, [resourceName2], ...)
Returns the resource ID for an extension resource. An extension resource is a resource type that's applied to another resource to add to its capabilities.
Namespace: az.
The extensionResourceId function is available in Bicep files, but typically you don't need it. Instead, use the symbolic name for the resource and access the id property.
The basic format of the resource ID returned by this function is:
{scope}/providers/{extensionResourceProviderNamespace}/{extensionResourceType}/{extensionResourceName}
The scope segment varies by the resource being extended.
When the extension resource is applied to a resource, the resource ID is returned in the following format:
/subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/{baseResourceProviderNamespace}/{baseResourceType}/{baseResourceName}/providers/{extensionResourceProviderNamespace}/{extensionResourceType}/{extensionResourceName}
When the extension resource is applied to a resource group, the format is:
/subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/{extensionResourceProviderNamespace}/{extensionResourceType}/{extensionResourceName}
When the extension resource is applied to a subscription, the format is:
/subscriptions/{subscriptionId}/providers/{extensionResourceProviderNamespace}/{extensionResourceType}/{extensionResourceName}
When the extension resource is applied to a management group, the format is:
/providers/Microsoft.Management/managementGroups/{managementGroupName}/providers/{extensionResourceProviderNamespace}/{extensionResourceType}/{extensionResourceName}
A custom policy definition deployed to a management group is implemented as an extension resource. To create and assign a policy, deploy the following Bicep file to a management group.
targetScope = 'managementGroup'
@description('An array of the allowed locations, all other locations will be denied by the created policy.')
param allowedLocations array = [
'australiaeast'
'australiasoutheast'
'australiacentral'
]
resource policyDefinition 'Microsoft.Authorization/policyDefinitions@2023-04-01' = {
name: 'locationRestriction'
properties: {
policyType: 'Custom'
mode: 'All'
parameters: {}
policyRule: {
if: {
not: {
field: 'location'
in: allowedLocations
}
}
then: {
effect: 'deny'
}
}
}
}
resource policyAssignment 'Microsoft.Authorization/policyAssignments@2024-04-01' = {
name: 'locationAssignment'
properties: {
policyDefinitionId: policyDefinition.id
}
}
Built-in policy definitions are tenant level resources. For an example of deploying a built-in policy definition, see tenantResourceId.
getSecret
keyVaultName.getSecret(secretName)
Returns a secret from an Azure Key Vault. Use this function to pass a secret to a secure string parameter of a Bicep module.
Note
az.getSecret(subscriptionId, resourceGroupName, keyVaultName, secretName, secretVersion) function can be used in .bicepparam files to retrieve key vault secrets. For more information, see getSecret.
You can only use the getSecret function from within the params section of a module. You can only use it with a Microsoft.KeyVault/vaults resource.
module sql './sql.bicep' = {
name: 'deploySQL'
params: {
adminPassword: keyVault.getSecret('vmAdminPassword')
}
}
You get an error if you attempt to use this function in any other part of the Bicep file. You also get an error if you use this function with string interpolation, even when used in the params section.
The function can be used only with a module parameter that has the @secure() decorator.
The key vault must have enabledForTemplateDeployment set to true. The user deploying the Bicep file must have access to the secret. For more information, see Use Azure Key Vault to pass secure parameter value during Bicep deployment.
A namespace qualifier isn't needed because the function is used with a resource type.
Parameters
| Parameter | Required | Type | Description |
|---|---|---|---|
| secretName | Yes | string | The name of the secret stored in a key vault. |
Return value
The secret value for the secret name.
Example
The following Bicep file is used as a module. It has an adminPassword parameter defined with the @secure() decorator.
param sqlServerName string
param adminLogin string
@secure()
param adminPassword string
resource sqlServer 'Microsoft.Sql/servers@2023-08-01-preview' = {
...
}
The following Bicep file consumes the preceding Bicep file as a module. The Bicep file references an existing key vault, and calls the getSecret function to retrieve the key vault secret, and then passes the value as a parameter to the module.
param sqlServerName string
param adminLogin string
param subscriptionId string
param kvResourceGroup string
param kvName string
resource keyVault 'Microsoft.KeyVault/vaults@2023-07-01' existing = {
name: kvName
scope: resourceGroup(subscriptionId, kvResourceGroup )
}
module sql './sql.bicep' = {
name: 'deploySQL'
params: {
sqlServerName: sqlServerName
adminLogin: adminLogin
adminPassword: keyVault.getSecret('vmAdminPassword')
}
}
list*
resourceName.list([apiVersion], [functionValues])
You can call a list function for any resource type with an operation that starts with list. Some common usages are list, listKeys, listKeyValue, and listSecrets.
The syntax for this function varies by the name of the list operation. The returned values also vary by operation. Bicep doesn't currently support completions and validation for list* functions.
With Bicep CLI version 0.4.X or higher, you call the list function by using the accessor operator. For example, storageAccount.listKeys().
A namespace qualifier isn't needed because the function is used with a resource type.
Parameters
| Parameter | Required | Type | Description |
|---|---|---|---|
| apiVersion | No | string | If you don't provide this parameter, the API version for the resource is used. Only provide a custom API version when you need the function to be run with a specific version. Use the format, yyyy-mm-dd. |
| functionValues | No | object | An object that has values for the function. Only provide this object for functions that support receiving an object with parameter values, such as listAccountSas on a storage account. An example of passing function values is shown in this article. |
Valid uses
The list functions can be used in the properties of a resource definition. Don't use a list function that exposes sensitive information in the outputs section of a Bicep file. Output values are stored in the deployment history and could be retrieved by a malicious user.
When used with an iterative loop, you can use the list functions for input because the expression is assigned to the resource property. You can't use them with count because the count must be determined before the list function is resolved.
If you use a list function in a resource that is conditionally deployed, the function is evaluated even if the resource isn't deployed. You get an error if the list function refers to a resource that doesn't exist. Use the conditional expression ?: operator to make sure the function is only evaluated when the resource is being deployed.
Return value
The returned object varies by the list function you use. For example, the listKeys for a storage account returns the following format:
{
"keys": [
{
"keyName": "key1",
"permissions": "Full",
"value": "{value}"
},
{
"keyName": "key2",
"permissions": "Full",
"value": "{value}"
}
]
}
Other list functions have different return formats. To see the format of a function, include it in the outputs section as shown in the example Bicep file.
List example
The following example deploys a storage account and then calls listKeys on that storage account. The key is used when setting a value for deployment scripts.
resource storageAccount 'Microsoft.Storage/storageAccounts@2023-04-01' = {
name: 'dscript${uniqueString(resourceGroup().id)}'
location: location
kind: 'StorageV2'
sku: {
name: 'Standard_LRS'
}
}
resource dScript 'Microsoft.Resources/deploymentScripts@2023-08-01' = {
name: 'scriptWithStorage'
location: location
...
properties: {
azCliVersion: '2.0.80'
storageAccountSettings: {
storageAccountName: storageAccount.name
storageAccountKey: storageAccount.listKeys().keys[0].value
}
...
}
}
The next example shows a list function that takes a parameter. In this case, the function is listAccountSas. Pass an object for the expiry time. The expiry time must be in the future.
param accountSasProperties object {
default: {
signedServices: 'b'
signedPermission: 'r'
signedExpiry: '2020-08-20T11:00:00Z'
signedResourceTypes: 's'
}
}
...
sasToken: storageAccount.listAccountSas('2021-04-01', accountSasProperties).accountSasToken

To determine which resource types have a list operation, you have the following options:
View the REST API operations for a resource provider, and look for list operations. For example, storage accounts have the listKeys operation.
Use the Get-AzProviderOperation PowerShell cmdlet. The following example gets all list operations for storage accounts:
Get-AzProviderOperation -OperationSearchString "Microsoft.Storage/*" | where {$_.Operation -like "*list*"} | FT OperationUse the following Azure CLI command to filter only the list operations:
az provider operation show --namespace Microsoft.Storage --query "resourceTypes[?name=='storageAccounts'].operations[].name | [?contains(@, 'list')]"
managementGroupResourceId
managementGroupResourceId(resourceType, resourceName1, [resourceName2], ...)
Returns the unique identifier for a resource deployed at the management group level.
Namespace: az.
The managementGroupResourceId function is available in Bicep files, but typically you don't need it. Instead, use the symbolic name for the resource and access the id property.
The identifier is returned in the following format:
/providers/Microsoft.Management/managementGroups/{managementGroupName}/providers/{resourceType}/{resourceName}
Remarks
You use this function to get the resource ID for resources that are deployed to the management group rather than a resource group. The returned ID differs from the value returned by the resourceId function by not including a subscription ID and a resource group value.
managementGroupResourceID example
The following template creates and assigns a policy definition. It uses the managementGroupResourceId function to get the resource ID for policy definition.
targetScope = 'managementGroup'
@description('Target Management Group')
param targetMG string
@description('An array of the allowed locations, all other locations will be denied by the created policy.')
param allowedLocations array = [
'australiaeast'
'australiasoutheast'
'australiacentral'
]
var mgScope = tenantResourceId('Microsoft.Management/managementGroups', targetMG)
var policyDefinitionName = 'LocationRestriction'
resource policyDefinition 'Microsoft.Authorization/policyDefinitions@2023-04-01' = {
name: policyDefinitionName
properties: {
policyType: 'Custom'
mode: 'All'
parameters: {}
policyRule: {
if: {
not: {
field: 'location'
in: allowedLocations
}
}
then: {
effect: 'deny'
}
}
}
}
resource location_lock 'Microsoft.Authorization/policyAssignments@2024-04-01' = {
name: 'location-lock'
properties: {
scope: mgScope
policyDefinitionId: managementGroupResourceId('Microsoft.Authorization/policyDefinitions', policyDefinitionName)
}
dependsOn: [
policyDefinition
]
}
pickZones
pickZones(providerNamespace, resourceType, location, [numberOfZones], [offset])
Determines whether a resource type supports zones for a region. This function only supports zonal resources. Zone redundant services return an empty array. For more information, see Azure services that support availability zones.
Namespace: az.
Parameters
| Parameter | Required | Type | Description |
|---|---|---|---|
| providerNamespace | Yes | string | The resource provider namespace for the resource type to check for zone support. |
| resourceType | Yes | string | The resource type to check for zone support. |
| location | Yes | string | The region to check for zone support. |
| numberOfZones | No | integer | The number of logical zones to return. The default is 1. The number must be a positive integer from 1 to 3. Use 1 for single-zoned resources. For multi-zoned resources, the value must be less than or equal to the number of supported zones. |
| offset | No | integer | The offset from the starting logical zone. The function returns an error if offset plus numberOfZones exceeds the number of supported zones. |
Return value
An array with the supported zones. When using the default values for offset and numberOfZones, a resource type and region that supports zones returns the following array:
[
"1"
]
When the numberOfZones parameter is set to 3, it returns:
[
"1",
"2",
"3"
]
When the resource type or region doesn't support zones, an empty array is returned.
[
]
Remarks
There are different categories for Azure Availability Zones - zonal and zone-redundant. The pickZones function can be used to return an availability zone for a zonal resource. For zone redundant services (ZRS), the function returns an empty array. Zonal resources typically have a zones property at the top level of the resource definition. To determine the category of support for availability zones, see Azure services that support availability zones.
To determine if a given Azure region or location supports availability zones, call the pickZones function with a zonal resource type, such as Microsoft.Network/publicIPAddresses. If the response isn't empty, the region supports availability zones.
pickZones example
The following Bicep file shows three results for using the pickZones function.
output supported array = pickZones('Microsoft.Compute', 'virtualMachines', 'westus2')
output notSupportedRegion array = pickZones('Microsoft.Compute', 'virtualMachines', 'westus')
output notSupportedType array = pickZones('Microsoft.Cdn', 'profiles', 'westus2')
The output from the preceding examples returns three arrays.
| Name | Type | Value |
|---|---|---|
| supported | array | [ "1" ] |
| notSupportedRegion | array | [] |
| notSupportedType | array | [] |
You can use the response from pickZones to determine whether to provide null for zones or assign virtual machines to different zones.
providers
The providers function has been deprecated in Bicep. We no longer recommend using it. If you used this function to get an API version for the resource provider, we recommend that you provide a specific API version in your Bicep file. Using a dynamically returned API version can break your template if the properties change between versions.
The providers operation is still available through the REST API. It can be used outside of a Bicep file to get information about a resource provider.
Namespace: az.
reference
reference(resourceName or resourceIdentifier, [apiVersion], ['Full'])
Returns an object representing a resource's runtime state. The output and behavior of the reference function highly relies on how each resource provider (RP) implements its PUT and GET responses.
Namespace: az.
The Bicep files provide access to the reference function, although it's typically unnecessary. Instead, it's recommended to use the symbolic name of the resource. The reference function can only be used within the properties object of a resource and can't be employed for top-level properties like name or location. The same generally applies to references using the symbolic name. However, for properties such as name, it's possible to generate a template without utilizing the reference function. Sufficient information about the resource name is known to directly emit the name. It's referred to as compile-time properties. Bicep validation can identify any incorrect usage of the symbolic name.
The following example deploys a storage account. The first two outputs give you the same results.
param storageAccountName string = uniqueString(resourceGroup().id)
param location string = resourceGroup().location
resource storageAccount 'Microsoft.Storage/storageAccounts@2023-04-01' = {
name: storageAccountName
location: location
kind: 'Storage'
sku: {
name: 'Standard_LRS'
}
}
output storageObjectSymbolic object = storageAccount.properties
output storageObjectReference object = reference('storageAccount')
output storageName string = storageAccount.name
output storageLocation string = storageAccount.location
To get a property from an existing resource that isn't deployed in the template, use the existing keyword:
param storageAccountName string
resource storageAccount 'Microsoft.Storage/storageAccounts@2023-04-01' existing = {
name: storageAccountName
}
// use later in template as often as needed
output blobAddress string = storageAccount.properties.primaryEndpoints.blob
To reference a resource that is nested inside a parent resource, use the nested accessor (::). You only use this syntax when you're accessing the nested resource from outside of the parent resource.
vNet1::subnet1.properties.addressPrefix
If you attempt to reference a resource that doesn't exist, you get the NotFound error and your deployment fails.
resourceId
resourceId([subscriptionId], [resourceGroupName], resourceType, resourceName1, [resourceName2], ...)
Returns the unique identifier of a resource.
Namespace: az.
The resourceId function is available in Bicep files, but typically you don't need it. Instead, use the symbolic name for the resource and access the id property.
You use this function when the resource name is ambiguous or not provisioned within the same Bicep file. The format of the returned identifier varies based on whether the deployment happens at the scope of a resource group, subscription, management group, or tenant.
For example:
param storageAccountName string
param location string = resourceGroup().location
resource storageAccount 'Microsoft.Storage/storageAccounts@2023-04-01' = {
name: storageAccountName
location: location
kind: 'Storage'
sku: {
name: 'Standard_LRS'
}
}
output storageID string = storageAccount.id
To get the resource ID for a resource that isn't deployed in the Bicep file, use the existing keyword.
param storageAccountName string
resource storageAccount 'Microsoft.Storage/storageAccounts@2023-04-01' existing = {
name: storageAccountName
}
output storageID string = storageAccount.id
For more information, see the JSON template resourceId function.
subscriptionResourceId
subscriptionResourceId([subscriptionId], resourceType, resourceName1, [resourceName2], ...)
Returns the unique identifier for a resource deployed at the subscription level.
Namespace: az.
The subscriptionResourceId function is available in Bicep files, but typically you don't need it. Instead, use the symbolic name for the resource and access the id property.
The identifier is returned in the following format:
/subscriptions/{subscriptionId}/providers/{resourceProviderNamespace}/{resourceType}/{resourceName}
Remarks
You use this function to get the resource ID for resources that are deployed to the subscription rather than a resource group. The returned ID differs from the value returned by the resourceId function by not including a resource group value.
subscriptionResourceID example
The following Bicep file assigns a built-in role. You can deploy it to either a resource group or subscription. It uses the subscriptionResourceId function to get the resource ID for built-in roles.
@description('Principal Id')
param principalId string
@allowed([
'Owner'
'Contributor'
'Reader'
])
@description('Built-in role to assign')
param builtInRoleType string
var roleDefinitionId = {
Owner: {
id: subscriptionResourceId('Microsoft.Authorization/roleDefinitions', '8e3af657-a8ff-443c-a75c-2fe8c4bcb635')
}
Contributor: {
id: subscriptionResourceId('Microsoft.Authorization/roleDefinitions', 'b24988ac-6180-42a0-ab88-20f7382dd24c')
}
Reader: {
id: subscriptionResourceId('Microsoft.Authorization/roleDefinitions', 'acdd72a7-3385-48ef-bd42-f606fba81ae7')
}
}
resource roleAssignment 'Microsoft.Authorization/roleAssignments@2022-04-01' = {
name: guid(resourceGroup().id, principalId, roleDefinitionId[builtInRoleType].id)
properties: {
roleDefinitionId: roleDefinitionId[builtInRoleType].id
principalId: principalId
}
}
tenantResourceId
tenantResourceId(resourceType, resourceName1, [resourceName2], ...)
Returns the unique identifier for a resource deployed at the tenant level.
Namespace: az.
The tenantResourceId function is available in Bicep files, but typically you don't need it. Instead, use the symbolic name for the resource and access the id property.
The identifier is returned in the following format:
/providers/{resourceProviderNamespace}/{resourceType}/{resourceName}
Built-in policy definitions are tenant level resources. To deploy a policy assignment that references a built-in policy definition, use the tenantResourceId function.
@description('Specifies the ID of the policy definition or policy set definition being assigned.')
param policyDefinitionID string = '0a914e76-4921-4c19-b460-a2d36003525a'
@description('Specifies the name of the policy assignment, can be used defined or an idempotent name as the defaultValue provides.')
param policyAssignmentName string = guid(policyDefinitionID, resourceGroup().name)
resource policyAssignment 'Microsoft.Authorization/policyAssignments@2024-04-01' = {
name: policyAssignmentName
properties: {
scope: subscriptionResourceId('Microsoft.Resources/resourceGroups', resourceGroup().name)
policyDefinitionId: tenantResourceId('Microsoft.Authorization/policyDefinitions', policyDefinitionID)
}
}
