Error: Reference to undeclared module on modules/site_recovery/main.tf
我已经在 terraform 中创建了资源、网络和计算模块，现在想将 vm_id 的输出传递给站点恢复模块，这里是我当前正在使用的文件。
继续主题：in resource "azurerm_site_recovery_replicated_vm" "vm-replication": source_vm_id= module.compute.vm_id

使用 depends_on 作为 site_recovery 模块的输入，请再次提出建议，我如何从计算模块输出托管磁盘 ID 和 Os 磁盘 ID，并在站点中使用输入恢复模块。
对于错误
Error: Reference to undeclared module on modules/site_recovery/main.tf
这意味着引用的模块没有在调用模块中声明。
调用模块意味着将该模块的内容包含到配置中，并为其输入变量指定特定值。使用 module 块从其他模块中调用模块。您需要在要调用该模块的配置 .tf 文件中添加 module 块。参见 calling a child module。
你的子站点恢复和计算main.tf好像没有声明模块块，所以你不能调用module.resource.azurerm_resource_group.primary.location、module.resource.azurerm_managed_disk.primary.id等资源模块上。
作为您的目录结构，您还可以使用输入变量从另一个模块输出调用模块。正确的表达是module.<MODULE NAME>.<OUTPUT NAME>。
要像这样从计算模块输出 VM id 和托管磁盘 id:
output "azurerm_vm_id" {
value = azurerm_virtual_machine.primary.id
}
output "primary_os_disk_id" {
value = azurerm_virtual_machine.primary.storage_os_disk[0].managed_disk_id
