Description

The New-AzPolicyAssignment cmdlet creates or updates a policy assignment with the given scope and name. Policy assignments apply to all resources contained within their scope. For example, when you assign a policy at resource group scope, that policy applies to all resources in the group.

Examples

Example 1: Policy assignment at subscription level

$Subscription = Get-AzSubscription -SubscriptionName 'Subscription01'
$Policy = Get-AzPolicyDefinition -Name 'VirtualMachinePolicy'
New-AzPolicyAssignment -Name 'VirtualMachinePolicyAssignment' -PolicyDefinition $Policy -Scope "/subscriptions/$($Subscription.Id)"

The first command gets a subscription named Subscription01 by using the Get-AzSubscription cmdlet and stores it in the $Subscription variable. The second command gets the policy definition named VirtualMachinePolicy by using the Get-AzPolicyDefinition cmdlet and stores it in the $Policy variable. The final command assigns the policy in $Policy at the level of the subscription identified by the subscription scope string.

Example 2: Policy assignment at resource group level

$ResourceGroup = Get-AzResourceGroup -Name 'ResourceGroup11'
$Policy = Get-AzPolicyDefinition -Name 'VirtualMachinePolicy'
New-AzPolicyAssignment -Name 'VirtualMachinePolicyAssignment' -PolicyDefinition $Policy -Scope $ResourceGroup.ResourceId

The first command gets a resource group named ResourceGroup11 by using the Get-AzResourceGroup cmdlet and stores it in the $ResourceGroup variable. The second command gets the policy definition named VirtualMachinePolicy by using the Get-AzPolicyDefinition cmdlet and stores it in the $Policy variable. The final command assigns the policy in $Policy at the level of the resource group identified by the ResourceId property of $ResourceGroup.

Example 3: Policy assignment at resource group level with policy parameter object

$ResourceGroup = Get-AzResourceGroup -Name 'ResourceGroup11'
$Policy = Get-AzPolicyDefinition -BuiltIn | Where-Object {$_.DisplayName -eq 'Allowed locations'}
$Locations = Get-AzLocation | Where-Object displayname -like '*east*'
$AllowedLocations = @{'listOfAllowedLocations'=($Locations.location)}
New-AzPolicyAssignment -Name 'RestrictLocationPolicyAssignment' -PolicyDefinition $Policy -Scope $ResourceGroup.ResourceId -PolicyParameterObject $AllowedLocations

The first command gets a resource group named ResourceGroup11 by using the Get-AzResourceGroup cmdlet. The command stores that object in the $ResourceGroup variable. The second command gets the built-in policy definition for allowed locations by using the Get-AzPolicyDefinition cmdlet. The command stores that object in the $Policy variable. The third and fourth commands create an object containing all Azure regions with "east" in the name. The commands store that object in the $AllowedLocations variable. The final command assigns the policy in $Policy at the level of a resource group using the policy parameter object in $AllowedLocations. The ResourceId property of $ResourceGroup identifies the resource group.

Example 4: Policy assignment at resource group level with policy parameter file

{
    "listOfAllowedLocations":  {
      "value": [
        "westus",
        "westeurope",
        "japanwest"
      ]
    }
}

$ResourceGroup = Get-AzResourceGroup -Name 'ResourceGroup11'
$Policy = Get-AzPolicyDefinition -BuiltIn | Where-Object {$_.DisplayName -eq 'Allowed locations'}
New-AzPolicyAssignment -Name 'RestrictLocationPolicyAssignment' -PolicyDefinition $Policy -Scope $ResourceGroup.ResourceId -PolicyParameter .\AllowedLocations.json

The first command gets a resource group named ResourceGroup11 by using the Get-AzResourceGroup cmdlet and stores it in the $ResourceGroup variable. The second command gets the built-in policy definition for allowed locations by using the Get-AzPolicyDefinition cmdlet and stores it in the $Policy variable. The final command assigns the policy in $Policy at the resource group identified by the ResourceId property of $ResourceGroup using the policy parameter file AllowedLocations.json from the local working directory.

Example 5: Policy assignment with a system assigned managed identity

$ResourceGroup = Get-AzResourceGroup -Name 'ResourceGroup11'
$Policy = Get-AzPolicyDefinition -Name 'VirtualMachinePolicy'
New-AzPolicyAssignment -Name 'VirtualMachinePolicyAssignment' -PolicyDefinition $Policy -Scope $ResourceGroup.ResourceId -Location 'eastus' -IdentityType 'SystemAssigned'

The first command gets a resource group named ResourceGroup11 by using the Get-AzResourceGroup cmdlet and stores it in the $ResourceGroup variable. The second command gets the policy definition named VirtualMachinePolicy by using the Get-AzPolicyDefinition cmdlet and stores it in the $Policy variable. The final command assigns the policy in $Policy to the resource group. A system assigned managed identity is automatically created and assigned to the policy assignment.

Example 6: Policy assignment with a user assigned managed identity

$ResourceGroup = Get-AzResourceGroup -Name 'ResourceGroup11'
$Policy = Get-AzPolicyDefinition -Name 'VirtualMachinePolicy'
$UserAssignedIdentity = Get-AzUserAssignedIdentity -ResourceGroupName 'ResourceGroup1' -Name 'UserAssignedIdentity1'
New-AzPolicyAssignment -Name 'VirtualMachinePolicyAssignment' -PolicyDefinition $Policy -Scope $ResourceGroup.ResourceId -Location 'eastus' -IdentityType 'UserAssigned' -IdentityId $UserAssignedIdentity.Id

The first command gets a resource group named ResourceGroup11 by using the Get-AzResourceGroup cmdlet and stores it in the $ResourceGroup variable. The second command gets the policy definition named VirtualMachinePolicy by using the Get-AzPolicyDefinition cmdlet and stores it in the $Policy variable. The third command gets the user assigned managed identity named UserAssignedIdentity1 by using the Get-AzUserAssignedIdentity cmdlet and stores it in the $UserAssignedIdentity variable. The final command assigns the policy in $Policy to the resource group. The user assigned managed identity identified by the Id property of $UserAssignedIdentity is assigned to the policy assignment by passing the Id* property to the IdentityId parameter.

Example 7: Policy assignment with an enforcement mode property

$Subscription = Get-AzSubscription -SubscriptionName 'Subscription01'
$Policy = Get-AzPolicyDefinition -Name 'VirtualMachinePolicy'
New-AzPolicyAssignment -Name 'VirtualMachinePolicyAssignment' -PolicyDefinition $Policy -Scope "/subscriptions/$($Subscription.Id)" -EnforcementMode DoNotEnforce

The first command gets a subscription named Subscription01 by using the Get-AzSubscription cmdlet and stores it in the $Subscription variable. The second command gets the policy definition named VirtualMachinePolicy by using the Get-AzPolicyDefinition cmdlet and stores it in the $Policy variable. The final command assigns the policy in $Policy at the level of the subscription identified by the subscription scope string.

The assignment is set with an EnforcementMode value of DoNotEnforce i.e. the policy effect is not enforced during resource creation or update.

Example 8: Policy assignment with non-compliance messages

$PolicySet = Get-AzPolicySetDefinition -Name 'VirtualMachinePolicySet'
$NonComplianceMessages = @(@{Message="Only DsV2 SKUs are allowed."; PolicyDefinitionReferenceId="DefRef1"}, @{Message="Virtual machines must follow cost management best practices."})
New-AzPolicyAssignment -Name 'VirtualMachinePolicyAssignment' -PolicySetDefinition $PolicySet -NonComplianceMessage $NonComplianceMessages

The first command gets the policy set definition named VirtualMachinePolicySet by using the Get-AzPolicySetDefinition cmdlet and stores it in the $PolicySet variable. The second command creates an array of non-compliance messages. One general purpose message for the entire assignment and one message specific to a SKU restriction policy within the assigned policy set definition. The final command assigns the policy set definition in $PolicySet to the subscription with two non-compliance messages that will be shown if a resource is denied by policy.

Example 9: [Backcompat] Policy assignment at resource group level with policy parameter object

$ResourceGroup = Get-AzResourceGroup -Name 'ResourceGroup11'
$Policy = Get-AzPolicyDefinition -BuiltIn | Where-Object {$_.Properties.DisplayName -eq 'Allowed locations'}
$Locations = Get-AzLocation | Where-Object displayname -like '*east*'
$AllowedLocations = @{'listOfAllowedLocations'=($Locations.location)}
New-AzPolicyAssignment -Name 'RestrictLocationPolicyAssignment' -PolicyDefinition $Policy -Scope $ResourceGroup.ResourceId -PolicyParameterObject $AllowedLocations

The first command gets a resource group named ResourceGroup11 by using the Get-AzResourceGroup cmdlet. The command stores that object in the $ResourceGroup variable. The second command gets the built-in policy definition for allowed locations by using the Get-AzPolicyDefinition cmdlet. The command stores that object in the $Policy variable. The third and fourth commands create an object containing all Azure regions with "east" in the name. The commands store that object in the $AllowedLocations variable. The final command assigns the policy in $Policy at the level of a resource group using the policy parameter object in $AllowedLocations. The ResourceId property of $ResourceGroup identifies the resource group.

Example 10: [Backcompat] Policy assignment at resource group level with policy parameter file

{
    "listOfAllowedLocations":  {
      "value": [
        "westus",
        "westeurope",
        "japanwest"
      ]
    }
}

$ResourceGroup = Get-AzResourceGroup -Name 'ResourceGroup11'
$Policy = Get-AzPolicyDefinition -BuiltIn | Where-Object {$_.Properties.DisplayName -eq 'Allowed locations'}
New-AzPolicyAssignment -Name 'RestrictLocationPolicyAssignment' -PolicyDefinition $Policy -Scope $ResourceGroup.ResourceId -PolicyParameter .\AllowedLocations.json

The first command gets a resource group named ResourceGroup11 by using the Get-AzResourceGroup cmdlet and stores it in the $ResourceGroup variable. The second command gets the built-in policy definition for allowed locations by using the Get-AzPolicyDefinition cmdlet and stores it in the $Policy variable. The final command assigns the policy in $Policy at the resource group identified by the ResourceId property of $ResourceGroup using the policy parameter file AllowedLocations.json from the local working directory.
