Synopsis

Calls the AWS Identity and Access Management GetRolePolicy API operation.

Syntax

Get-IAMRolePolicy
-RoleName <String>
-PolicyName <String>
-Select <String>
-PassThru <SwitchParameter>

Description

Retrieves the specified inline policy document that is embedded with the specified IAM role. Policies returned by this operation are URL-encoded compliant with RFC 3986. You can use a URL decoding method to convert the policy back to plain JSON text. For example, if you use Java, you can use the decode method of the java.net.URLDecoder utility class in the Java SDK. Other languages and SDKs provide similar functionality. An IAM role can also have managed policies attached to it. To retrieve a managed policy document that is attached to a role, use GetPolicy to determine the policy's default version, then use GetPolicyVersion to retrieve the policy document. For more information about policies, see Managed policies and inline policies in the IAM User Guide. For more information about roles, see Using roles to delegate permissions and federate identities.

Parameters

-PassThru <SwitchParameter>
Changes the cmdlet behavior to return the value passed to the RoleName parameter. The -PassThru parameter is deprecated, use -Select '^RoleName' instead. This parameter will be removed in a future version.
Required?False
Position?Named
Accept pipeline input?True (ByPropertyName)
-PolicyName <String>
The name of the policy document to get.This parameter allows (through its regex pattern) a string of characters consisting of upper and lowercase alphanumeric characters with no spaces. You can also include any of the following characters: _+=,.@-
Required?True
Position?2
Accept pipeline input?True (ByPropertyName)
-RoleName <String>
The name of the role associated with the policy.This parameter allows (through its regex pattern) a string of characters consisting of upper and lowercase alphanumeric characters with no spaces. You can also include any of the following characters: _+=,.@-
Required?True
Position?1
Accept pipeline input?True (ByValue, ByPropertyName)
-Select <String>
Use the -Select parameter to control the cmdlet output. The default value is '*'. Specifying -Select '*' will result in the cmdlet returning the whole service response (Amazon.IdentityManagement.Model.GetRolePolicyResponse). Specifying the name of a property of type Amazon.IdentityManagement.Model.GetRolePolicyResponse 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)

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)
AliasesST

Outputs

Amazon.IdentityManagement.Model.GetRolePolicyResponse
This cmdlet returns an Amazon.IdentityManagement.Model.GetRolePolicyResponse object containing multiple properties. The object can also be referenced from properties attached to the cmdlet entry in the $AWSHistory stack.

Examples

Example 1

$results = Get-IAMRolePolicy -RoleName lambda_exec_role -PolicyName oneClick_lambda_exec_role_policy
$results
     
PolicyDocument                                            PolicyName                           UserName
--------------                                            ----------                           --------
%7B%0A%20%20%22Version%22%3A%20%222012-10-17%22%2C%...    oneClick_lambda_exec_role_policy     lambda_exec_role

[System.Reflection.Assembly]::LoadWithPartialName("System.Web.HttpUtility")
[System.Web.HttpUtility]::UrlDecode($results.PolicyDocument)
{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Effect": "Allow",
      "Action": [
        "logs:*"
      ],
      "Resource": "arn:aws:logs:*:*:*"
    },
    {
      "Effect": "Allow",
      "Action": [
        "s3:GetObject",
        "s3:PutObject"
      ],
      "Resource": [
        "arn:aws:s3:::*"
      ]
    }
  ]
}
This example returns the permissions policy document for the policy named oneClick_lambda_exec_role_policy that is embedded in the IAM role lamda_exec_role. The resulting policy document is URL encoded. It is decoded in this example with the UrlDecode .NET method.
