Question

我正在尝试根据环境更改堆栈名称。我尝试了以下方法：

stack_name = "intl-${var.intl_region}-${var.intl_ctry}-${var.intl_env}-jk-${var.vanity_env == "-np" || var.vanity_env == "-dr"} ? "mstr" : "master"}"

但出现以下错误：

错误：解析错误 /build_workspace/workspace/GCM/PIPE_JENKINS/main.tf：在33:25：嵌套预期对象：LBRACE获得：ASSIGN

能不能帮我如何根据环境更改堆栈名称？

应为：

if a == a || b ? "c ": "d"

如此：

a==b==c else d

您在这里的三元语法有点错误：

stack_name = intl-${var.intl_region}-${var.intl_ctry}-${var.intl_env}-jk-${var.vanity_env == "-np" || var.vanity_env == "-dr" ? "mstr" : "master"}

请注意，整个三元语句都位于${}构造内。

作为一个完整的例子：

variable "intl_region" {
  default = "foo"
}

variable "intl_ctry" {
  default = "bar"
}

variable "intl_env" {
  default = "baz"
}

variable "vanity_env" {}

output "foo" {
  value = "intl-${var.intl_region}-${var.intl_ctry}-${var.intl_env}-jk-${var.vanity_env == "-np" || var.vanity_env == "-dr" ? "mstr" : "master"}"
}

并运行它：

$ TF_VAR_vanity_env=-np terraform apply

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

Outputs:

foo = intl-foo-bar-baz-jk-mstr
$ TF_VAR_vanity_env=-dr terraform apply

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

Outputs:

foo = intl-foo-bar-baz-jk-mstr
$ TF_VAR_vanity_env=quux terraform apply

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

Outputs:

foo = intl-foo-bar-baz-jk-master

如何在Terraform中使用else-if else条件
