虚拟机规模设置使用terraform没有负载平衡器?

Question

我试图通过Terraform部署虚拟机规模集扩展，但这里有几个问题，要求是在没有负载均衡器附加的情况下实现

resource "azurerm_virtual_machine_scale_set" "example" {
name                = "mytestscaleset-1"
location            = azurerm_resource_group.example.location
resource_group_name = azurerm_resource_group.example.name
# automatic rolling upgrade
# automatic_os_upgrade = true
upgrade_policy_mode  = "Rolling"
rolling_upgrade_policy {
max_batch_instance_percent              = 20
max_unhealthy_instance_percent          = 20
max_unhealthy_upgraded_instance_percent = 5
pause_time_between_batches              = "PT0S"
}
sku {
name     = "Standard_F2"
tier     = "Standard"
capacity = 2
}
storage_profile_image_reference {
publisher = "Canonical"
offer     = "UbuntuServer"
sku       = "16.04-LTS"
version   = "latest"
}
storage_profile_os_disk {
name              = ""
caching           = "ReadWrite"
create_option     = "FromImage"
managed_disk_type = "Standard_LRS"
}
storage_profile_data_disk {
lun           = 0
caching       = "ReadWrite"
create_option = "Empty"
disk_size_gb  = 10
}
os_profile {
computer_name_prefix = "testvm"
admin_username       = "myadmin"
}
os_profile_linux_config {
disable_password_authentication = true
ssh_keys {
path     = "/home/myadmin/.ssh/authorized_keys"
key_data = file("C:/Users/User/Downloads/VmSS key/azkey")
}
}
network_profile {
name    = "terraformnetworkprofile"
primary = true
ip_configuration {
name                                   = "TestIPConfiguration"
primary                                = true
subnet_id                              = azurerm_subnet.example.id
public_ip_address_configuration    {
name              = "Avx192"
idle_timeout      = 30
domain_name_label = "vjst23"
}

}
}
tags = {
environment = "staging"
}
}

一旦部署，其健康探测的给出错误

│ Error: compute.VirtualMachineScaleSetsClient#CreateOrUpdate: Failure sending request: StatusCode=0 -- Original Error: Code="BadRequest" Message="Rolling Upgrade mode is not supported for this Virtual Machine Scale Set because a health probe or health extension was not provided."
│

如果部署没有附加负载平衡器，如何直接提供运行状况探测?

Answer 1

在没有负载平衡器的情况下进行部署。因此，您需要在代码中做以下更改:

1. 将upgrade_policy_mode = "Rolling"更改为upgrade_policy_mode = "Manual"/"Automatic"
2. 删除下面的代码块:

rolling_upgrade_policy {
max_batch_instance_percent              = 20
max_unhealthy_instance_percent          = 20
max_unhealthy_upgraded_instance_percent = 5
pause_time_between_batches              = "PT0S"
}
