Synopsis

Invokes the GetClusterCredentials operation against Amazon Redshift.

Syntax

Get-RSClusterCredential
-ClusterIdentifier <String>
-AutoCreate <Boolean>
-DbGroup <String[]>
-DbName <String>
-DbUser <String>
-DurationSecond <Int32>

Description

Returns a database user name and temporary password with temporary authorization to log in to an Amazon Redshift database. The action returns the database user name prefixed with IAM: if AutoCreate is False or IAMA: if AutoCreate is True. You can optionally specify one or more database user groups that the user will join at log in. By default, the temporary credentials expire in 900 seconds. You can optionally specify a duration between 900 seconds (15 minutes) and 3600 seconds (60 minutes). For more information, see Generating IAM Database User Credentials in the Amazon Redshift Cluster Management Guide. The IAM user or role that executes GetClusterCredentials must have an IAM policy attached that allows the redshift:GetClusterCredentials action with access to the dbuser resource on the cluster. The user name specified for dbuser in the IAM policy and the user name specified for the DbUser parameter must match. If the DbGroups parameter is specified, the IAM policy must allow the redshift:JoinGroup action with access to the listed dbgroups. In addition, if the AutoCreate parameter is set to True, then the policy must include the redshift:CreateClusterUser privilege. If the DbName parameter is specified, the IAM policy must allow access to the resource dbname for the specified database name.

Parameters

-AutoCreate <Boolean>
Create a database user with the name specified for DbUser if one does not exist.
Required?False
Position?Named
Accept pipeline input?False
-ClusterIdentifier <String>
The unique identifier of the cluster that contains the database for which your are requesting credentials. This parameter is case sensitive.
Required?False
Position?1
Accept pipeline input?True (ByValue, ByPropertyName)
-DbGroup <String[]>
A list of the names of existing database groups that DbUser will join for the current session. If not specified, the new user is added only to PUBLIC.
Required?False
Position?Named
Accept pipeline input?False
-DbName <String>
The name of a database that DbUser is authorized to log on to. If DbName is not specified, DbUser can log in to any existing database.Constraints:
  • Must be 1 to 64 alphanumeric characters or hyphens
  • Must contain only lowercase letters.
  • Cannot be a reserved word. A list of reserved words can be found in Reserved Words in the Amazon Redshift Database Developer Guide.
Required?False
Position?Named
Accept pipeline input?False
-DbUser <String>
The name of a database user. If a user name matching DbUser exists in the database, the temporary user credentials have the same permissions as the existing user. If DbUser doesn't exist in the database and Autocreate is True, a new user is created using the value for DbUser with PUBLIC permissions. If a database user matching the value for DbUser doesn't exist and Autocreate is False, then the command succeeds but the connection attempt will fail because the user doesn't exist in the database.For more information, see CREATE USER in the Amazon Redshift Database Developer Guide. Constraints:
  • Must be 1 to 128 alphanumeric characters or hyphens
  • Must contain only lowercase letters.
  • First character must be a letter.
  • Must not contain a colon ( : ) or slash ( / ).
  • Cannot be a reserved word. A list of reserved words can be found in Reserved Words in the Amazon Redshift Database Developer Guide.
Required?False
Position?Named
Accept pipeline input?False
-DurationSecond <Int32>
The number of seconds until the returned temporary password expires.Constraint: minimum 900, maximum 3600.Default: 900
Required?False
Position?Named
Accept pipeline input?False

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 ClusterIdentifier parameter.

Outputs

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