Synopsis

Calls the Amazon Simple Storage Service (S3) GetBucketPolicy API operation.

Syntax

Get-S3BucketPolicy
-BucketName <String>
-ExpectedBucketOwner <String>
-Select <String>
-PassThru <SwitchParameter>
-UseAccelerateEndpoint <SwitchParameter>
-UseDualstackEndpoint <SwitchParameter>
-ForcePathStyleAddressing <Boolean>

Description

Returns the policy of a specified bucket. If you are using an identity other than the root user of the AWS account that owns the bucket, the calling identity must have the GetBucketPolicy permissions on the specified bucket and belong to the bucket owner's account in order to use this operation. If you don't have GetBucketPolicy permissions, Amazon S3 returns a 403 Access Denied error. If you have the correct permissions, but you're not using an identity that belongs to the bucket owner's account, Amazon S3 returns a 405 Method Not Allowed error. As a security precaution, the root user of the AWS account that owns a bucket can always use this operation, even if the policy explicitly denies the root user the ability to perform this action. For more information about bucket policies, see Using Bucket Policies and User Policies. The following operation is related to GetBucketPolicy:

Parameters

-BucketName <String>
The name of the bucket.
Required?False
Position?1
Accept pipeline input?True (ByValue, ByPropertyName)
-ExpectedBucketOwner <String>
The account id of the expected bucket owner. If the bucket is owned by a different account, the request will fail with an HTTP 403 (Access Denied) error.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-ForcePathStyleAddressing <Boolean>
S3 requests can be performed using one of two URI styles: Virtual or Path. When using Virtual style, the bucket is included as part of the hostname. When using Path style the bucket is included as part of the URI path. The default value is $true when the EndpointUrl parameter is specified, $false otherwise.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-PassThru <SwitchParameter>
Changes the cmdlet behavior to return the value passed to the BucketName parameter. The -PassThru parameter is deprecated, use -Select '^BucketName' instead. This parameter will be removed in a future version.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-Select <String>
Use the -Select parameter to control the cmdlet output. The default value is 'Policy'. Specifying -Select '*' will result in the cmdlet returning the whole service response (Amazon.S3.Model.GetBucketPolicyResponse). Specifying the name of a property of type Amazon.S3.Model.GetBucketPolicyResponse will result in that property being returned. Specifying -Select '^ParameterName' will result in the cmdlet returning the selected cmdlet parameter value.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-UseAccelerateEndpoint <SwitchParameter>
Enables S3 accelerate by sending requests to the accelerate endpoint instead of the regular region endpoint. To use this feature, the bucket name must be DNS compliant and must not contain periods (.).
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-UseDualstackEndpoint <SwitchParameter>
Configures the request to Amazon S3 to use the dualstack endpoint for a region. S3 supports dualstack endpoints which return both IPv6 and IPv4 values. The dualstack mode of Amazon S3 cannot be used with accelerate mode.
Required?False
Position?Named
Accept pipeline input?True (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?True (ByPropertyName)
AliasesAK
-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?True (ByValue, ByPropertyName)
-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?True (ByPropertyName)
-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?True (ByValue, ByPropertyName)
-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.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?True (ByPropertyName)
AliasesAWSProfilesLocation, ProfilesLocation
-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?True (ByPropertyName)
AliasesStoredCredentials, AWSProfileName
-Region <Object>
The system name of an AWS region or an AWSRegion instance. This governs the endpoint that will be used when calling service operations. Note that the AWS resources referenced in a call are usually region-specific.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
AliasesRegionToCall
-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?True (ByPropertyName)
AliasesSK, SecretAccessKey
-SessionToken <String>
The session token if the access and secret keys are temporary session-based credentials.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
