Terraform：无法从 azurerm_network_interface 检索 ID

Question

为什么这对我不起作用？我见过这段代码在任何地方都能正常工作，但我一直收到以下错误。真令人沮丧……

Error: Error running plan: 1 error(s) occurred:

* azurerm_virtual_machine.main: 2 error(s) occurred:

看起来您构造的设置 Count 并未生成预期的资源数组，而是生成了单个资源。

您应该能够通过调用来验证是否已启用调试日志运行TF_LOG=DEBUG terraform plan。
