# InstanceRequirements
<a name="sam-property-capacityprovider-instancerequirements"></a>

指定将由容量提供商启动的 EC2 实例的要求，包括架构和实例类型限制。

## 语法
<a name="sam-property-capacityprovider-instancerequirements-syntax"></a>

要在 AWS Serverless Application Model (AWS SAM) 模板中声明此实体，请使用以下语法。

### YAML
<a name="sam-property-capacityprovider-instancerequirements-syntax.yaml"></a>

```
[Architectures](#sam-capacityprovider-instancerequirements-architectures): List
[AllowedTypes](#sam-capacityprovider-instancerequirements-allowedtypes): List
[ExcludedTypes](#sam-capacityprovider-instancerequirements-excludedtypes): List
```

**注意**  
您可以选择在为容量提供商定义实例要求`ExcludedTypes`时指定其中一个`AllowedTypes`或一个，但不能同时指定两者。
