Synopsis

Invokes the DeletePolicy operation against AWS Identity and Access Management.

Syntax

Remove-IAMPolicy
-PolicyArn <String>
-PassThru <SwitchParameter>
-Force <SwitchParameter>

Description

Deletes the specified managed policy. Before you can delete a managed policy, you must first detach the policy from all users, groups, and roles that it is attached to, and you must delete all of the policy's versions. The following steps describe the process for deleting a managed policy:
  • Detach the policy from all users, groups, and roles that the policy is attached to, using the DetachUserPolicy, DetachGroupPolicy, or DetachRolePolicy APIs. To list all the users, groups, and roles that a policy is attached to, use ListEntitiesForPolicy.
  • Delete all versions of the policy using DeletePolicyVersion. To list the policy's versions, use ListPolicyVersions. You cannot use DeletePolicyVersion to delete the version that is marked as the default version. You delete the policy's default version in the next step of the process.
  • Delete the policy (this automatically deletes the policy's default version) using this API.
For information about managed policies, see Managed Policies and Inline Policies in the IAM User Guide.

Parameters

-Force <SwitchParameter>
This parameter overrides confirmation prompts to force the cmdlet to continue its operation. This parameter should always be used with caution.
Required?False
Position?Named
Accept pipeline input?False
-PassThru <SwitchParameter>
Returns the value passed to the PolicyArn parameter. By default, this cmdlet does not generate any output.
Required?False
Position?Named
Accept pipeline input?False
-PolicyArn <String>
The Amazon Resource Name (ARN) of the IAM policy you want to delete.For more information about ARNs, see Amazon Resource Names (ARNs) and AWS Service Namespaces in the AWS General Reference.
Required?False
Position?1
Accept pipeline input?True (ByValue, ByPropertyName)

Common Credential and Region Parameters

-AccessKey <String>
The AWS access key for the user account. This can be a temporary access key if the corresponding session token is supplied to the -SessionToken parameter.
Required? False
Position? Named
Accept pipeline input? False
-Credential <AWSCredentials>
An AWSCredentials object instance containing access and secret key information, and optionally a token for session-based credentials.
Required? False
Position? Named
Accept pipeline input? False
-ProfileLocation <String>

Used to specify the name and location of the ini-format credential file (shared with the AWS CLI and other AWS SDKs)

If this optional parameter is omitted this cmdlet will search the encrypted credential file used by the AWS SDK for .NET and AWS Toolkit for Visual Studio first. If the profile is not found then the cmdlet will search in the ini-format credential file at the default location: (user's home directory)\.aws\credentials. Note that the encrypted credential file is not supported on all platforms. It will be skipped when searching for profiles on Windows Nano Server, Mac, and Linux platforms.

If this parameter is specified then this cmdlet will only search the ini-format credential file at the location given.

As the current folder can vary in a shell or during script execution it is advised that you use specify a fully qualified path instead of a relative path.

Required? False
Position? Named
Accept pipeline input? False
-ProfileName <String>
The user-defined name of an AWS credentials or SAML-based role profile containing credential information. The profile is expected to be found in the secure credential file shared with the AWS SDK for .NET and AWS Toolkit for Visual Studio. You can also specify the name of a profile stored in the .ini-format credential file used with the AWS CLI and other AWS SDKs.
Required? False
Position? Named
Accept pipeline input? False
-NetworkCredential <PSCredential>
Used with SAML-based authentication when ProfileName references a SAML role profile. Contains the network credentials to be supplied during authentication with the configured identity provider's endpoint. This parameter is not required if the user's default network identity can or should be used during authentication.
Required? False
Position? Named
Accept pipeline input? False
-SecretKey <String>
The AWS secret key for the user account. This can be a temporary secret key if the corresponding session token is supplied to the -SessionToken parameter.
Required? False
Position? Named
Accept pipeline input? False
-SessionToken <String>
The session token if the access and secret keys are temporary session-based credentials.
Required? False
Position? Named
Accept pipeline input? False
-Region <String>
The system name of the AWS region in which the operation should be invoked. For example, us-east-1, eu-west-1 etc.
Required? False
Position? Named
Accept pipeline input? False
-EndpointUrl <String>

The endpoint to make the call against.

Note: This parameter is primarily for internal AWS use and is not required/should not be specified for normal usage. The cmdlets normally determine which endpoint to call based on the region specified to the -Region parameter or set as default in the shell (via Set-DefaultAWSRegion). Only specify this parameter if you must direct the call to a specific custom endpoint.

Required? False
Position? Named
Accept pipeline input? False

Inputs

You can pipe a String object to this cmdlet for the PolicyArn parameter.

Outputs

None or System.String
When you use the PassThru parameter, this cmdlet outputs the value supplied to the PolicyArn parameter. Otherwise, this cmdlet does not return any output. The service response (type Amazon.IdentityManagement.Model.DeletePolicyResponse) can be referenced from properties attached to the cmdlet entry in the $AWSHistory stack.

Examples

Example 1

PS C:\>Remove-IAMPolicy -PolicyArn arn:aws:iam::123456789012:policy/MySamplePolicy
This example deletes the policy whose ARN is arn:aws:iam::123456789012:policy/MySamplePolicy. Before you can delete the policy, you must first delete all versions except the default by running Remove-IAMPolicyVersion. You must also detach the policy from any IAM users, groups, or roles.

Example 2

PS C:\>$pol = Get-IAMPolicy -PolicyArn arn:aws:iam::123456789012:policy/MySamplePolicy
PS C:\>Get-IAMPolicyVersions -PolicyArn $pol.Arn | where {-not $_.IsDefaultVersion} | Remove-IAMPolicyVersion -PolicyArn $pol.Arn -force
PS C:\>$attached = Get-IAMEntitiesForPolicy -PolicyArn $pol.Arn
PS C:\>$attached.PolicyGroups | Unregister-IAMGroupPolicy -PolicyArn $pol.arn
PS C:\>$attached.PolicyRoles | Unregister-IAMRolePolicy -PolicyArn $pol.arn
PS C:\>$attached.PolicyUsers | Unregister-IAMUserPolicy -PolicyArn $pol.arn
PS C:\>Remove-IAMPolicy $pol.Arn -Force
This example deletes a policy by first deleting all the non-default policy versions, detaching it from all attached IAM entities, and finally deleting the policy itself. The first line retrieves the policy object. The second line retrieves all the policy versions that are not flagged as the default version into a collection and then deletes each policy in the collection. The third line retrieves all of the IAM users, groups, and roles to which the policy is attached. Lines four through six detach the policy from each attached entity. The last line uses this command to remove the managed policy as well as the remaining default version. The example includes the -Force switch parameter on any line that needs it to suppress prompts for confirmation.
