使用 Terraform 在 Linux VM 上运行脚本扩展

如何解决使用 Terraform 在 Linux VM 上运行脚本扩展

我正在尝试使用自定义脚本扩展在 Azure Linux VM 规模集上运行 bash 脚本，我已将脚本上传到 Azure 存储帐户。 bash 脚本用于在 VM Scaleset 上安装 ngix。该脚本运行时没有任何错误，但是如果我登录到任何 VMScaleset 实例进行验证，我看不到 NGIX 正在运行。 Bash 脚本在这里

#!/bin/bash
apt-get update 
apt-get install -y Nginx

这里的地形文件

  name                 = var.subnetName1
  virtual_network_name = var.vnetName
  resource_group_name  = var.resourceGroupName
}

    "fileUris": ["https://xxxxxxxxxxx.blob.core.windows.net/shellscript11/post-deploy.sh"],"commandToExecute": "sh post-deploy.sh"
    }

}

解决方法

参考 this document，您可以像这样使用发布者和类型自定义脚本。

resource "azurerm_virtual_machine_scale_set_extension" "res-extension" {
  name                         = "nnn-extension"
  virtual_machine_scale_set_id = azurerm_linux_virtual_machine_scale_set.example.id
  publisher                    = "Microsoft.Azure.Extensions"
  type                         = "CustomScript"
  type_handler_version         = "2.0"
  settings = jsonencode({ 
    "fileUris" = ["https://xxxx.blob.core.windows.net/shscripts/aptupdate.sh"],"commandToExecute" = "sh aptupdate.sh"
    }
  )
}

应用上述配置后，您可以upgrade每个 vmss 实例，然后 Nginx 将运行。
