如何解决使用Terraform基于参数化名称创建多个aws_cloudformation_stack
是否可以基于参数化名称在Terraform中使用一个 Process: com.gamze.pawsbook,PID: 30879

资源定义创建多个CloutFormation堆栈？
我定义了以下资源，并且希望每个aws_cloudformation_stack，app_name app_env组合都有一个堆栈：
build_name当resource "aws_s3_bucket_object" "sam_deploy_object" {
bucket = var.sam_bucket
key = "${var.app_env}/${var.build_name}/sam_template_${timestamp()}.yaml"
source = "../.aws-sam/sam_template_output.yaml"
etag = filemd5("../.aws-sam/sam_template_output.yaml")
}
resource "aws_cloudformation_stack" "subscriptions_sam_stack" {
name = "${var.app_name}---${var.app_env}--${var.build_name}"
capabilities = ["CAPABILITY_NAMED_IAM","CAPABILITY_AUTO_EXPAND"]
template_url = "https://${var.sam_bucket}.s3-${data.aws_region.current.name}.amazonaws.com/${aws_s3_bucket_object.sam_deploy_object.id}"
}
名称更改时运行terraform apply时，旧堆栈将被删除并创建一个新堆栈，但是我想保留旧堆栈并创建一个新堆栈
解决方法
一种方法是将变量//add bar
$("#btn-Newbar").on("click",function() {
$("#hbar").append("<div class='col-4' style='margin-bottom:20px;'><div class='row'><div class='col-3'><img src='' class='catHpic' style='height:80px;width:80px;'></div><div class='col-9'><input type='file' class='hpicFile'><div class='input-group mb-3' style='margin-top:10px;'><div class='input-group-prepend'><span class='input-group-text url'>URL</span></div><input type='text' class='form-control' aria-describedby='basic-addon1'></div></div></div></div>");
});
//display highlight pic real time
$(document).on("change",".hpicFile",function(e) {
var imgSrc = $(this).parent('div').prev().find('.catHpic') //find img
if (e.target.files[0] != null) {
//console.log(e.target.files[0]);
$.each(this.files,function(key,file) {
var reader = new FileReader();
reader.onload = function(e) {
//display images real time
imgSrc.attr('src',e.target.result);
}
reader.readAsDataURL(file);
});
}
});定义为列表。然后，当您创建新的内部版本时，只需将它们附加到列表中，并借助for_each创建堆栈以遍历内部版本名称。
例如，如果您具有以下条件：
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div class="card-body">
<div class="row" id="hbar">
</div>
</div>
<div class="card-footer" style="text-align:right;">
<button class="btn btn-secondary" id="btn-Newbar">New Bar</button>
</div>然后，如果要为堆栈进行第二次构建，则只需扩展build_name：
variable "app_name" {
default = "test1"
}
variable "app_env" {
default = "test2"
}
variable "build_name" {
default = ["test3"]
}
resource "aws_cloudformation_stack" "subscriptions_sam_stack" {
for_each = toset(var.build_name)
name = "${var.app_name}---${var.app_env}--${each.value}"
capabilities = ["CAPABILITY_NAMED_IAM","CAPABILITY_AUTO_EXPAND"]
template_url = "https://${var.sam_bucket}.s3-${data.aws_region.current.name}.amazonaws.com/${aws_s3_bucket_object.sam_deploy_object.id}"
}
