容器实例仅在从 ARM 模板首次部署时运行

Question

我正在尝试通过 ARM 模板创建具有文件共享的存储帐户。为此，我创建了存储帐户，然后在容器实例 as described here 中运行 az CLI 命令。

模板部署得很好，但问题是容器只在第一次运行时启动。后续部署不会导致容器实例启动，因此如果文件共享已被删除（人为错误），则不会重新创建。

我无法使用完整的部署，因为资源组中还有其他资源。

我已经咨询了documentation，但那里似乎没有任何相关内容。

有没有办法告诉容器实例总是启动？

这是我正在使用的示例模板 -

如果您在使用 az container delete 之间从 Azure 门户或通过 az cli 手动删除 ACI，会怎样。据我了解，Azure 容器实例是一次性的。当我想部署新容器时，我通常只是删除旧容器。当然，这通常由 Jenkins 等 CI&CD 管道完成。

编辑： ARM-template 仅在找不到资源时才启动容器，但因为它确实找到了 ACI，所以它什么也不做。恕我直言，您不应该使用 ARM 模板进行容器管理。
