[英]Iterating through a Terraform object list variable and outputting string value
could use some guidance here.可以在这里使用一些指导。
I have the following list variable that holds two string values (name, short_name) for many US States:我有以下列表变量,其中包含许多美国州的两个字符串值(名称、短名称):
variable "states" {
type = list(object({
name = string
short_name = string
}))
description = "State List"
default = [
{
name = "New Jersey"
short_name = "nj"
},
{
name = "Michigan"
short_name = "mi"
]
}
I need to iterate through this list and output each index for the "short_name" string into a generic code block in my common.tfvars file.我需要遍历此列表和 output 将“short_name”字符串的每个索引放入我的 common.tfvars 文件中的通用代码块中。
The code block looks something like this and contains only strings:代码块看起来像这样并且只包含字符串:
generic_code_block = [
"Stateofnj"
"Stateofmi"
]
I want to adjust this code block so only one line of code needs to be written and it will iterate through the list for the short_name string value.我想调整此代码块,因此只需要编写一行代码,它将遍历 short_name 字符串值的列表。
Is this possible for a generic code block where a resource is not being created?这对于未创建资源的通用代码块是否可行?
I imagine a concept similar to this could work but I'm not exactly sure how to put it together.我想象一个类似于此的概念可以工作,但我不确定如何将它组合在一起。
generic_code_block = [
"Stateof" + for_each = toSet(var.States.short_name) + "
]
Would appreciate any help thank you.将不胜感激任何帮助谢谢。
This can be accomplished by a simple for
loop:这可以通过一个简单
for
循环来完成:
variable "states" {
type = list(object({
name = string
short_name = string
}))
description = "State List"
default = [
{
name = "New Jersey"
short_name = "nj"
},
{
name = "Michigan"
short_name = "mi"
}
]
}
locals {
generic_code_block = [
for state in var.states: "Stateof${state.short_name}"
]
}
You can use the local variable as such:您可以这样使用局部变量:
output "generic_code_block " {
value = local.generic_code_block
}
