要删除实例配置文件

以下 delete-instance-profile 命令将删除名为 ExampleInstanceProfile 的实例配置文件。

aws iam delete-instance-profile \
    --instance-profile-name ExampleInstanceProfile

此命令不生成任何输出。

有关更多信息，请参阅《Amazon IAM 用户指南》中的使用实例配置文件。

      const client = new IAMClient({});
      await client.send(
        new DeleteInstanceProfileCommand({
          InstanceProfileName: NAMES.instanceProfileName,
        }),
      );

示例 1：此示例删除名为 MyAppInstanceProfile 的 EC2 实例配置文件。第一条命令从实例配置文件中分离所有角色，然后第二条命令删除实例配置文件。

(Get-IAMInstanceProfile -InstanceProfileName MyAppInstanceProfile).Roles | Remove-IAMRoleFromInstanceProfile -InstanceProfileName MyAppInstanceProfile
Remove-IAMInstanceProfile -InstanceProfileName MyAppInstanceProfile

此示例从实例配置文件中移除该角色，分离附加到该角色的所有策略，然后删除所有资源。
