attachRolePolicy

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.

Samples

fun main() { 
   //sampleStart 
   // The following command attaches the AWS managed policy named ReadOnlyAccess to the IAM role named
// ReadOnlyRole.
iamClient.attachRolePolicy {
    roleName = "ReadOnlyRole"
    policyArn = "arn:aws:iam::aws:policy/ReadOnlyAccess"
} 
   //sampleEnd
