create-service-linked-role¶

Description¶

Creates an IAM role that is linked to a specific Amazon Web Services service. The service controls the attached policies and when the role can be deleted. This helps ensure that the service is not broken by an unexpectedly changed or deleted role, which could put your Amazon Web Services resources into an unknown state. Allowing the service to control the role helps improve service stability and proper cleanup when a service and its role are no longer needed. For more information, see Using service-linked roles in the IAM User Guide .

To attach a policy to this service-linked role, you must make the request using the Amazon Web Services service that depends on this role.

Synopsis¶

  create-service-linked-role
--aws-service-name <value>
[--description <value>]
[--custom-suffix <value>]
[--cli-input-json | --cli-input-yaml]
[--generate-cli-skeleton <value>]

Options¶

--aws-service-name (string)

The service principal for the Amazon Web Services service to which this role is attached. You use a string similar to a URL but without the http:// in front. For example: elasticbeanstalk.amazonaws.com .

Service principals are unique and case-sensitive. To find the exact service principal for your service-linked role, see Amazon Web Services services that work with IAM in the IAM User Guide . Look for the services that have Yes in the Service-Linked Role column. Choose the Yes link to view the service-linked role documentation for that service.

--description (string)

The description of the role.

--custom-suffix (string)

A string that you provide, which is combined with the service-provided prefix to form the complete role name. If you make multiple requests for the same service, then you must supply a different CustomSuffix for each request. Otherwise the request fails with a duplicate role name error. For example, you could add -1 or -debug to the suffix.

Some services do not support the CustomSuffix parameter. If you provide an optional suffix and the operation fails, try the operation again without the suffix.

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

See ‘aws help’ for descriptions of global parameters.

Examples¶

To create a service-linked role

The following create-service-linked-role example creates a service-linked role for the specified AWS service and attaches the specified description.

aws iam create-service-linked-role \
    --aws-service-name lex.amazonaws.com \
    --description "My service-linked role to support Lex"

Output:

{
    "Role": {
        "Path": "/aws-service-role/lex.amazonaws.com/",
        "RoleName": "AWSServiceRoleForLexBots",
        "RoleId": "AROA1234567890EXAMPLE",
        "Arn": "arn:aws:iam::1234567890:role/aws-service-role/lex.amazonaws.com/AWSServiceRoleForLexBots",
        "CreateDate": "2019-04-17T20:34:14+00:00",
        "AssumeRolePolicyDocument": {
            "Version": "2012-10-17",
            "Statement": [
                {
                    "Action": [
                        "sts:AssumeRole"
                    ],
                    "Effect": "Allow",
                    "Principal": {
                        "Service": [
                            "lex.amazonaws.com"
                        ]
                    }
                }
            ]
        }
    }
}

Output¶

Role -> (structure)

A Role object that contains details about the newly created role.

Path -> (string)

The path to the role. For more information about paths, see IAM identifiers in the IAM User Guide .

RoleName -> (string)

The friendly name that identifies the role.

RoleId -> (string)

The stable and unique string identifying the role. For more information about IDs, see IAM identifiers in the IAM User Guide .

Arn -> (string)

The Amazon Resource Name (ARN) specifying the role. For more information about ARNs and how to use them in policies, see IAM identifiers in the IAM User Guide guide.

CreateDate -> (timestamp)

The date and time, in ISO 8601 date-time format , when the role was created.

AssumeRolePolicyDocument -> (string)

The policy that grants an entity permission to assume the role.

Description -> (string)

A description of the role that you provide.

MaxSessionDuration -> (integer)

The maximum session duration (in seconds) for the specified role. Anyone who uses the CLI, or API to assume the role can specify the duration using the optional DurationSeconds API parameter or duration-seconds CLI parameter.

PermissionsBoundary -> (structure)

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

For more information about permissions boundaries, see Permissions boundaries for IAM identities in the IAM User Guide .

PermissionsBoundaryType -> (string)

The permissions boundary usage type that indicates what type of IAM resource is used as the permissions boundary for an entity. This data type can only have a value of Policy .

PermissionsBoundaryArn -> (string)

The ARN of the policy used to set the permissions boundary for the user or role.

Tags -> (list)

A list of tags that are attached to the role. For more information about tagging, see Tagging IAM resources in the IAM User Guide .

(structure)

A structure that represents user-provided metadata that can be associated with an IAM resource. For more information about tagging, see Tagging IAM resources in the IAM User Guide .

Key -> (string)

The key name that can be used to look up or retrieve the associated value. For example, Department or Cost Center are common choices.

Value -> (string)

The value associated with this tag. For example, tags with a key name of Department could have values such as Human Resources , Accounting , and Support . Tags with a key name of Cost Center might have values that consist of the number associated with the different cost centers in your company. Typically, many resources have tags with the same key name but with different values.

Note

Amazon Web Services always interprets the tag Value as a single string. If you need to store an array, you can store comma-separated values in the string. However, you must interpret the value in your code.

RoleLastUsed -> (structure)

Contains information about the last time that an IAM role was used. This includes the date and time and the Region in which the role was last used. Activity is only reported for the trailing 400 days. This period can be shorter if your Region began supporting these features within the last year. The role might have been used more than 400 days ago. For more information, see Regions where data is tracked in the IAM User Guide .

LastUsedDate -> (timestamp)

The date and time, in ISO 8601 date-time format that the role was last used.

This field is null if the role has not been used within the IAM tracking period. For more information about the tracking period, see Regions where data is tracked in the IAM User Guide .

Region -> (string)

The name of the Amazon Web Services Region in which the role was last used.
