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 https://docs.aws.amazon.com/IAM/latest/APIReference/API_CreateRole.html`__ . You can update a role's trust policy using ` UpdateAssumerolePolicy https://docs.aws.amazon.com/IAM/latest/APIReference/API_UpdateAssumeRolePolicy.html`__ .

Use this operation to attach a managed policy to a role. To embed an inline policy in a role, use ` PutRolePolicy https://docs.aws.amazon.com/IAM/latest/APIReference/API_PutRolePolicy.html`__ . For more information about policies, see Managed policies and inline policies in the IAM User Guide .

As a best practice, you can validate your IAM policies. To learn more, see Validating IAM policies in the IAM User Guide .

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) in the Amazon Web Services General Reference .

--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI 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.

--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. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

Global Options

--debug (boolean)

Turn on debug logging.

--endpoint-url (string)

Override command's default URL with the given URL.

--no-verify-ssl (boolean)

By default, the AWS CLI uses SSL when communicating with AWS services. For each SSL connection, the AWS CLI will verify SSL certificates. This option overrides the default behavior of verifying SSL certificates.

--no-paginate (boolean)

Disable automatic pagination. If automatic pagination is disabled, the AWS CLI will only make one call, for the first page of results.

--output (string)

The formatting style for command output.

  • json
  • text
  • table

--query (string)

A JMESPath query to use in filtering the response data.

--profile (string)

Use a specific profile from your credential file.

--region (string)

The region to use. Overrides config/env settings.

--version (string)

Display the version of this tool.

--color (string)

Turn on/off color output.

  • on
  • off
  • auto

--no-sign-request (boolean)

Do not sign requests. Credentials will not be loaded if this argument is provided.

--ca-bundle (string)

The CA certificate bundle to use when verifying SSL certificates. Overrides config/env settings.

--cli-read-timeout (int)

The maximum socket read time in seconds. If the value is set to 0, the socket read will be blocking and not timeout. The default value is 60 seconds.

--cli-connect-timeout (int)

The maximum socket connect time in seconds. If the value is set to 0, the socket connect will be blocking and not timeout. The default value is 60 seconds.

Examples

Note

To use the following examples, you must have the AWS CLI installed and configured. See the Getting started guide in the AWS CLI User Guide for more information.

Unless otherwise stated, all examples have unix-like quotation rules. These examples will need to be adapted to your terminal's quoting rules. See Using quotation marks with strings in the AWS CLI User Guide .

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

This command produces no output.
