Get Cluster Credentials

redshift_get_cluster_credentials

R Documentation

Returns a database user name and temporary password with temporary authorization to log on to an Amazon Redshift database

Description

Returns a database user name and temporary password with temporary authorization to log on 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 on. 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 Using IAM Authentication to Generate Database User Credentials in the Amazon Redshift Cluster Management Guide.

The Identity and Access Management (IAM) user or role that runs GetClusterCredentials must have an IAM policy attached that allows access to all necessary actions and resources. For more information about permissions, see Resource Policies for GetClusterCredentials in the Amazon Redshift Cluster Management Guide.

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 permission.

If the DbName parameter is specified, the IAM policy must allow access to the resource dbname for the specified database name.

Usage

redshift_get_cluster_credentials(DbUser, DbName, ClusterIdentifier,
  DurationSeconds, AutoCreate, DbGroups, CustomDomainName)

Arguments

DbUser	[required] 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 64 alphanumeric characters or hyphens. The user name can't be PUBLIC. Must contain uppercase or lowercase letters, numbers, underscore, plus sign, period (dot), at symbol (@), or hyphen. 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.
DbName	The name of a database that DbUser is authorized to log on to. If DbName is not specified, DbUser can log on to any existing database. Constraints: Must be 1 to 64 alphanumeric characters or hyphens Must contain uppercase or lowercase letters, numbers, underscore, plus sign, period (dot), at symbol (@), or hyphen. 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.
ClusterIdentifier	The unique identifier of the cluster that contains the database for which you are requesting credentials. This parameter is case sensitive.
DurationSeconds	The number of seconds until the returned temporary password expires. Constraint: minimum 900, maximum 3600. Default: 900
AutoCreate	Create a database user with the name specified for the user named in DbUser if one does not exist.
DbGroups	A list of the names of existing database groups that the user named in DbUser will join for the current session, in addition to any group memberships for an existing user. If not specified, a new user is added only to PUBLIC. Database group name constraints Must be 1 to 64 alphanumeric characters or hyphens Must contain only lowercase letters, numbers, underscore, plus sign, period (dot), at symbol (@), or hyphen. 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.
CustomDomainName	The custom domain name for the cluster credentials.
