#### [ CLI ]

**AWS CLI**  
**刪除 IAM 角色**  
下列 `delete-role` 命令會將名為 `Test-Role` 的角色移除。  

```
aws iam delete-role \
    --role-name Test-Role
```
此命令不會產生輸出。  
刪除角色之前，您必須先從任何執行個體設定檔 (`remove-role-from-instance-profile`) 移除該角色、分離任何受管政策 (`detach-role-policy`)，並刪除任何連接至該角色的內嵌政策 (`delete-role-policy`)。  
如需詳細資訊，請參閱《AWS IAM 使用者指南》**中的[建立 IAM 角色](https://docs.aws.amazon.com/IAM/latest/UserGuide/id_roles_create.html)和[使用執行個體設定檔](https://docs.aws.amazon.com/IAM/latest/UserGuide/id_roles_use_switch-role-ec2_instance-profiles.html)。

**Tools for PowerShell V4**  
**範例 1：此範例會從目前的 IAM 帳戶刪除名為 `MyNewRole` 的角色。在刪除角色之前，必須先使用 `Unregister-IAMRolePolicy` 命令來分離任何受管政策。內嵌政策會與角色一起刪除。**  

```
Remove-IAMRole -RoleName MyNewRole
```
**範例 2：此範例會從名為 `MyNewRole` 的角色分離任何受管政策，然後刪除該角色。第一行將連接至角色的任何受管政策擷取為集合，然後讓集合中的每個政策與角色分離。第二行刪除角色本身。內嵌政策會與角色一起刪除。**  

```
