如何打印 terraform 变量值？

如何解决如何打印 terraform 变量值？

我正在学习地形。我想在“计划”阶段打印变量的值。所以我找到了怎么做。似乎我在这里做错了什么......

在 variables.tf:....

variable "VMCount" {
    description = "How many VMs do you want to start with (number)? default=1 max=5"
    type = number
}

在 main.tf 中

output "VMCount" {
  value = "${var.VMCount > 2 && var.VMCount < 6 ? var.VMCount : 2}"
}

在那之后我运行了 terraform 计划并且条件似乎工作正常（它创建了正确数量的虚拟机）

但是变量输出没有来。为什么？

$ terraform output
VMC = 56

VMC 可能来自之前的一些尝试（我尝试了几种方法）。

如何打印用户输入的值（变量）？

谢谢。

解决方法

我用这个测试过：

variable "VMCount" {
    description = "How many VMs do you want to start with (number)? default=1 max=5"
    type = number
}

output "VMCount" {
  value = "${var.VMCount > 2 && var.VMCount < 6 ? var.VMCount : 2}"
}

而且效果很好。

Terraform will perform the following actions:

Plan: 0 to add,0 to change,0 to destroy.

Changes to Outputs:
  + VMCount = 4

Do you want to perform these actions?
  Terraform will perform the actions described above.
  Only 'yes' will be accepted to approve.

  Enter a value: yes


Apply complete! Resources: 0 added,0 changed,0 destroyed.

Outputs:

VMCount = 4
PS C:\d\m\terraform\output-and-variable> terraform output
VMCount = 4
PS C:\d\m\terraform\output-and-variable> terraform apply
var.VMCount
  How many VMs do you want to start with (number)? default=1 max=5

  Enter a value: 8


Terraform used the selected providers to generate the following execution plan. Resource actions are indicated with the following symbols:

Terraform will perform the following actions:

Plan: 0 to add,0 to destroy.

Changes to Outputs:
  ~ VMCount = 4 -> 2

Do you want to perform these actions?
  Terraform will perform the actions described above.
  Only 'yes' will be accepted to approve.

  Enter a value: yes


Apply complete! Resources: 0 added,0 destroyed.

Outputs:

VMCount = 2
PS C:\d\m\terraform\output-and-variable> terraform output
VMCount = 2
PS C:\d\m\terraform\output-and-variable>

你能检查一下你在州有哪些出局吗？ VMC 还是 VMCount？
