> 创建多个相同资源 # count 官方例子 https://developer.hashicorp.com/terraform/language/meta-arguments/count ``` resource "aws_instance" "server" { count = 4 # create four similar EC2 instances ami = "ami-a1b2c3d4" instance_type = "t2.micro" tags = { Name = "Server ${count.index}" } } ``` 用数组方式调用一个元素 ``` variable "subnet_ids" { type = list(string) } resource "aws_instance" "server" { # Create one instance for each subnet count = length(var.subnet_ids) ami = "ami-a1b2c3d4" instance_type = "t2.micro" subnet_id = var.subnet_ids[count.index] #这里 tags = { Name = "Server ${count.index}" } } ``` # for_each 官方例子 https://developer.hashicorp.com/terraform/language/meta-arguments/for_each ``` #map resource "azurerm_resource_group" "rg" { for_each = { a_group = "eastus" another_group = "westus2" } name = each.key location = each.value } #set resource "aws_iam_user" "the-accounts" { for_each = toset( ["Todd", "James", "Alice", "Dottie"] ) name = each.key } ```
