我有一个terraform在运行时失败的文件，terraform plan并且出现错误：
Error: Cycle: module.hosting.data.template_file.bucket_policy, module.hosting.aws_s3_bucket.website
这是有道理的，因为存储桶引用了策略，反之亦然：
data "template_file" "bucket_policy" {
template = file("${path.module}/policy.json")
vars = {
bucket = aws_s3_bucket.website.arn
}
}
resource "aws_s3_bucket" "website" {
bucket = "xxx-website"
website {
index_document = "index.html"
}
policy = data.template_file.bucket_policy.rendered
}
如何避免这种双向引用？
您可以自己构建存储桶的ARN：
locals {
bucket_name = "example"
bucket_arn = "arn:aws:s3:::${local.bucket_name}"
}
data "template_file" "bucket_policy" {
template = file("${path.module}/policy.json")
vars = {
bucket = local.bucket_arn
}
}
resource "aws_s3_bucket" "website" {
bucket = local.bucket_name
website {
index_document = "index.html"
}
policy = data.template_file.bucket_policy.rendered
}
