## 建立 服務連結角色
<a name="vpc-slr-creating"></a>

當您使用 `CreateConfiguration` API 建立第一個 VPC 組態時，會自動建立服務連結角色。您必須擁有下列 IAM 許可：

```
{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Effect": "Allow",
      "Action": "iam:CreateServiceLinkedRole",
      "Resource": "arn:aws:iam::*:role/aws-service-role/omics.amazonaws.com/AWSServiceRoleForHealthOmics",
      "Condition": {
        "StringEquals": {
          "iam:AWSServiceName": "omics.amazonaws.com"
        }
      }
    }
  ]
}
```

## 刪除 服務連結角色
<a name="vpc-slr-deleting"></a>

只有在刪除帳戶中的所有 VPC 組態後，您才能刪除服務連結角色。若要刪除角色：

```
aws iam delete-service-linked-role \
  --role-name AWSServiceRoleForHealthOmics
```

如果您有作用中的 VPC 組態，刪除將會失敗，並顯示必須先刪除哪些組態資源的訊息。
