此外，**托管身份**也会被创建，以便来自仓库的Github Action能够使用它登录到Azure。这是通过在**托管身份**上生成一个联邦凭证来完成的，允许**发行者** `https://token.actions.githubusercontent.com` 和**主题标识符** `repo:<org-name>/<repo-name>:ref:refs/heads/<branch-name>`。

> [!CAUTION]
> 因此，任何妥协该仓库的人都将能够妥协该函数及其附加的托管身份。

### 基于容器的部署

并非所有计划都允许部署容器，但对于允许的计划，配置将包含容器的URL。在API中，**`linuxFxVersion`** 设置将类似于： `DOCKER|mcr.microsoft.com/...`，而在Web控制台中，配置将显示**镜像设置**。

此外，**与该函数相关的存储账户中不会存储任何源代码**，因为不需要。
