AWS Identity and Access Management: New-IAMRole Cmdlet

Synopsis

Calls the AWS Identity and Access Management CreateRole API operation.

Syntax

New-IAMRole
-Path <String>
-RoleName <String>
-AssumeRolePolicyDocument <String>
-Description <String>
-MaxSessionDuration <Int32>
-PermissionsBoundary <String>
-Tag <Tag[]>
-Force <SwitchParameter>

Description

Creates a new role for your AWS account. For more information about roles, go to IAM Roles. For information about limitations on role names and the number of roles you can create, go to Limitations on IAM Entities in the IAM User Guide.

Parameters

-AssumeRolePolicyDocument <String>

The trust relationship policy document that grants an entity permission to assume the role.In IAM, you must provide a JSON policy that has been converted to a string. However, for AWS CloudFormation templates formatted in YAML, you can provide the policy in JSON or YAML format. AWS CloudFormation always converts a YAML policy to JSON format before submitting it to IAM.The regex pattern used to validate this parameter is a string of characters consisting of the following:

Any printable ASCII character ranging from the space character (\u0020) through the end of the ASCII character range
The printable characters in the Basic Latin and Latin-1 Supplement character set (through \u00FF)
The special characters tab (\u0009), line feed (\u000A), and carriage return (\u000D)

Upon success, the response includes the same trust policy as a URL-encoded JSON string.

Required?	False
Position?	3
Accept pipeline input?	False

-Description <String>

A description of the role.

Required?	False
Position?	Named
Accept pipeline input?	False

-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

-MaxSessionDuration <Int32>

The maximum session duration (in seconds) that you want to set for the specified role. If you do not specify a value for this setting, the default maximum of one hour is applied. This setting can have a value from 1 hour to 12 hours.Anyone who assumes the role from the AWS CLI or API can use the DurationSeconds API parameter or the duration-seconds CLI parameter to request a longer session. The MaxSessionDuration setting determines the maximum duration that can be requested using the DurationSeconds parameter. If users don't specify a value for the DurationSeconds parameter, their security credentials are valid for one hour by default. This applies when you use the AssumeRole* API operations or the assume-role* CLI operations but does not apply when you use those operations to create a console URL. For more information, see Using IAM Roles in the IAM User Guide.

Required?	False
Position?	Named
Accept pipeline input?	False

-Path <String>

The path to the role. For more information about paths, see IAM Identifiers in the IAM User Guide.This parameter is optional. If it is not included, it defaults to a slash (/).This parameter allows (through its regex pattern) a string of characters consisting of either a forward slash (/) by itself or a string that must begin and end with forward slashes. In addition, it can contain any ASCII character from the ! (\u0021) through the DEL character (\u007F), including most punctuation characters, digits, and upper and lowercased letters.

Required?	False
Position?	1
Accept pipeline input?	True (ByValue, ByPropertyName)

-PermissionsBoundary <String>

The ARN of the policy that is used to set the permissions boundary for the role.

Required?	False
Position?	Named
Accept pipeline input?	False

-RoleName <String>

The name of the role to create.IAM user, group, role, and policy names must be unique within the account. Names are not distinguished by case. For example, you cannot create resources named both "MyResource" and "myresource".

Required?	False
Position?	2
Accept pipeline input?	True (ByPropertyName)

-Tag <Tag[]>

A list of tags that you want to attach to the newly created role. Each tag consists of a key name and an associated value. For more information about tagging, see Tagging IAM Identities in the IAM User Guide.If any one of the tags is invalid or if you exceed the allowed number of tags per role, then the entire request fails and the role is not created.

Required?	False
Position?	Named
Accept pipeline input?	False
Aliases	Tags

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

System.String

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

Outputs

Amazon.IdentityManagement.Model.Role

This cmdlet returns a Amazon.IdentityManagement.Model.Role object. The service call response (type Amazon.IdentityManagement.Model.CreateRoleResponse) can also be referenced from properties attached to the cmdlet entry in the $AWSHistory stack.

This example creates a new role named MyNewRole and attaches to it the policy found in the file NewRoleTrustPolicy.json. Note that you must use the -Raw switch parameter to successfully process the JSON policy file. The policy document displayed in the output is URL encoded. It is decoded in this example with the UrlDecode .NET method.
