Use DeleteRolePolicy with an AWS SDK or CLI

    /// <summary>
    /// Delete an IAM role policy.
    /// </summary>
    /// <param name="roleName">The name of the IAM role.</param>
    /// <param name="policyName">The name of the IAM role policy to delete.</param>
    /// <returns>A Boolean value indicating the success of the action.</returns>
    public async Task<bool> DeleteRolePolicyAsync(string roleName, string policyName)
    {
        var response = await _IAMService.DeleteRolePolicyAsync(new DeleteRolePolicyRequest
        {
            PolicyName = policyName,
            RoleName = roleName,
        });

        return response.HttpStatusCode == System.Net.HttpStatusCode.OK;
    }

To remove a policy from an IAM role

The following delete-role-policy command removes the policy named ExamplePolicy from the role named Test-Role.

aws iam delete-role-policy \
    --role-name Test-Role \
    --policy-name ExamplePolicy

This command produces no output.

For more information, see Modifying a role in the AWS IAM User Guide.

import { DeleteRolePolicyCommand, IAMClient } from "@aws-sdk/client-iam";

const client = new IAMClient({});

/**
 *
 * @param {string} roleName
 * @param {string} policyName
 */
export const deleteRolePolicy = (roleName, policyName) => {
  const command = new DeleteRolePolicyCommand({
    RoleName: roleName,
    PolicyName: policyName,
  });
  return client.send(command);
};

Example 1: This example deletes the inline policy S3AccessPolicy that is embedded in the IAM role S3BackupRole.

Remove-IAMRolePolicy -PolicyName S3AccessPolicy -RoleName S3BackupRole
