Class AttachRolePolicyCommandProtected

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.

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 operation 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.

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

Example

Use a bare-bones client and the command you need to make an API call.

import { IAMClient, AttachRolePolicyCommand } from "@aws-sdk/client-iam"; // ES Modules import
// const { IAMClient, AttachRolePolicyCommand } = require("@aws-sdk/client-iam"); // CommonJS import
const client = new IAMClient(config);
const input = { // AttachRolePolicyRequest
RoleName: "STRING_VALUE", // required
PolicyArn: "STRING_VALUE", // required
};
const command = new AttachRolePolicyCommand(input);
const response = await client.send(command);
// {};
