如何使用用户管理的身份部署 ARM 模板并分配订阅级别角色？

Question

下面的 ARM 模板应该创建以下资源：

resource group
    - user managed identity
       - subscription level Contributor role assignment

当前部署失败并出现错误 "error": { "code": "ResourceGroupNotFound", "message": "Resource group 'rg-myproject-deploy' could not be found." } 显然是因为角色分配步骤似乎没有遵守 dependsOn 应该强制执行的语句，它应该只在资源组创建后发生.有没有办法在一个 ARM 模板中部署所有这些资源？

我认为你运行喜欢这个：

修复比我想象的要复杂一些，但总结一下：

提供 MI 的嵌套部署必须设置为内部范围评估
从该部署中输出 principalId 并在您的引用中使用它（即不要直接引用）

由于#1，我移动了一些东西 (params/vars)
