无法通过 SSH 连接到 Azure 虚拟机

这是为什么？以及如何才能最终连接到 VM。
我在我的环境中测试了您的代码，它已成功部署，但是在执行 SSH 时它出错并显示 连接超时。
起初我使用 azurerm_linux_virtual_machine 而不是 azurerm_virtual_machine 来修改它，正如 Terraform 文档 下面提到的，但它仍然失败。
The azurerm_virtual_machine resource has been superseded by the
azurerm_linux_virtual_machine and azurerm_windows_virtual_machine
resources. The existing azurerm_virtual_machine resource will continue
to be available throughout the 2.x releases however is in a
feature-frozen state to maintain compatibility - new functionality
will instead be added to the azurerm_linux_virtual_machine and
azurerm_windows_virtual_machine resources.
因此，作为解决方案，我通过使用以下代码删除 NSG rule 和 NSG association with NIC 再次测试，结果成功。您不需要在 NSG 中添加 SSH 端口 作为 默认情况下 Azure 检查 OS 是否为 Windows 然后它将打开 RDP 如果 Linux 则 SSH 端口将被打开。
