我正在创建一个 ARM 模板，用于实现 Function App 从创建到代码部署的自动化部署。 Function App 在 Linux (Python) 上配置，当用户上传图像时，它会激活 Blob 触发器以进行图像处理。要使用 ARM 模板实现此目的，必要的步骤是：
我正在遵循 Stack Overflow 说明，并且我的具体场景与以下 stackoverflow 帖子（缩短了 URL）中提供的详细信息一致： https://shorturl.at/GJ247
我使用的代码参考了上面的帖子：

我目前正在努力实施该解决方案，但我在部署页面上遇到了错误。有人可以指导我创建它吗？在 Function App 中创建函数时发生错误。这可能是因为里面没有代码，还是有其他潜在的问题？

创建 ARM 模板时，创建一个脚本文件，将其保存在脚本文件夹中，并将上述用于部署函数的所有命令粘贴到 Function App。
注意：- 在 mainTemplate.json 文件中定义 VM 的 ARM 模板。如果您不需要虚拟机，则可以在功能部署后删除虚拟机。
您的 zip 文件应遵循以下结构。
Azuretemplate.zip
scripts(folder)/script.sh
createUiDefinition.json
mainTemplate.json
viewDefinition.json
创建 zip 文件并尝试部署它。
