# 添加启动模板
<a name="project-launch-template"></a>

创建或编辑项目时，您可以使用项目配置中的**高级选项**添加启动模板。启动模板为项目中的所有 VDI 实例提供了其他配置，例如安全组、IAM 策略和启动脚本。

## 添加策略
<a name="add-policies"></a>

您可以添加 IAM 策略来控制在您的项目下部署的所有实例的 VDI 访问权限。要加入策略，请使用以下键值对标记该策略：

```
res:Resource/vdi-host-policy
```

有关 IAM 角色的更多信息，请参阅 I [AM 中的策略和权限](https://docs.aws.amazon.com/IAM/latest/UserGuide/access_policies.html)。

### 添加安全组
<a name="add-security-groups"></a>

您可以添加安全组来控制项目下所有 VDI 实例的出口和入口数据。要加入安全组，请使用以下键值对标记该安全组：

```
res:Resource/vdi-security-group
```

有关安全组的更多信息，请参阅 *Amazon VPC 用户指南*中的[使用安全组控制 AWS 资源流量](https://docs.aws.amazon.com/vpc/latest/userguide/vpc-security-groups.html)。

### 添加启动脚本
<a name="project-launch-scripts"></a>

您可以添加启动脚本，这些脚本将在项目中的所有 VDI 会话中启动。RES 支持 Linux 和 Windows 的脚本初始化。要启动脚本，您可以选择以下任一选项：

**VDI 启动时运行脚本**  
在任何 RES 配置或安装运行之前，此选项在 VDI 实例的开头启动脚本。

**配置 VDI 后运行脚本**  
此选项在 RES 配置完成后启动脚本。

脚本支持以下选项：


| 脚本配置 | 示例 | 
| --- | --- | 
| S3 URI | s3://bucketname/script.sh | 
| HTTPS URL | https://sample.samplecontent.com/sample | 
| 本地文件 | 文件:///.sh user/scripts/example | 

托管在 S3 存储桶上的所有自定义脚本都需要使用以下标签进行配置：

```
res:EnvironmentName/<res-environment>
```

对于**参数**，请提供用逗号分隔的所有参数。
