attach-role-policy¶

Description¶

Attaches the specified managed policy to the specified IAM role. When you attach a managed policy to a role, the managed policy becomes part of the role’s permission (access) policy.

Note

You cannot use a managed policy as the role’s trust policy. The role’s trust policy is created at the same time as the role, using CreateRole . You can update a role’s trust policy using UpdateAssumeRolePolicy .

Use this API to attach a managed policy to a role. To embed an inline policy in a role, use PutRolePolicy . For more information about policies, see Managed Policies and Inline Policies in the IAM User Guide .

Synopsis¶

  attach-role-policy
--role-name <value>
--policy-arn <value>
[--cli-input-json | --cli-input-yaml]
[--generate-cli-skeleton <value>]

Options¶

--role-name (string)

The name (friendly name, not ARN) of the role to attach the policy to.

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: _+=,.@-

--policy-arn (string)

The Amazon Resource Name (ARN) of the IAM policy you want to attach.

For more information about ARNs, see Amazon Resource Names (ARNs) and AWS Service Namespaces in the AWS General Reference .

--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 attach a managed policy to an IAM role

The following attach-role-policy command attaches the AWS managed policy named ReadOnlyAccess to the IAM role named ReadOnlyRole:

aws iam attach-role-policy --policy-arn arn:aws:iam::aws:policy/ReadOnlyAccess --role-name ReadOnlyRole
