Terraform – for_each的使用

for_each 可以loop set或者map ， 那么就能批量创建资源

使用案例1：loop set

each.value 和 each.key 获取的值都是一样的

provider "aws" {
  region = "ap-southeast-1"
}

variable "setdata" {
  type = set(string)
  default = ["kiat","alice"]
}

resource "aws_iam_user" "iam" {
  for_each = var.setdata
  name     = each.value

  tags = {
    Name = "user-${each.key}"
  }
}

输出结果：

使用案例2：

loop map , each.key 可以读取map的key

provider "aws" {
  region = "ap-southeast-1"
}

variable "setdata" {
  type = map(string)
  default = {
    dev  = "alice"
    prod = "kiat"
  }
}

resource "aws_iam_user" "iam" {
  for_each = var.setdata
  name     = each.value

  tags = {
    Name = "user-${each.key}"
  }
}

输出结果：
