作业始终在 Terraform 中更新

Question

我正在使用列表（对象）（水名称配置）格式的变量部署 AWS Glue 作业列表（水名称）。当 Terraforms 检查部署计划时，即使变量没有更改，它总是会出现差异。我怀疑它默认实现动态变量。

我的实现代码如下：

resource "aws_glue_job" "water-name" {
  count       = length(var.funny-name-configs)
  name        = "water-name-${var.water-name-configs[count.index].table_name}"
  description = "water-name-${var.water-name-configs[count.index].table_name}"

你能检查一下我哪里出错了吗？

我确实尝试向作业添加依赖项。

depends_on = [var.water_name]

我希望能够避免重做所有 terrafrom 代码，为数组 water-name 的每个元素声明一个变量。

我测试了您的代码，组成了变量的内容和其余代码：

variable "funny-name-configs" {
  default = ["a", "b"]
}

variable "water-name-configs" {
  default = [{table_name:"a"},{table_name:"b"}]
}

resource "aws_glue_job" "water-name" {
  count       = length(var.funny-name-configs)
  name        = "water-name-${var.water-name-configs[count.index].table_name}"
  description = "water-name-${var.water-name-configs[count.index].table_name}"

  role_arn = "arn:aws:iam::621655500000:role/aws-service-role/support/AX"
  command {
    script_location = "s3://foo/example.py"
  }
}

如果我运行多个应用，我们可以看到它第一次创建资源，并且以下应用看不到任何变化

Plan: 2 to add, 0 to change, 0 to destroy.

aws_glue_job.water-name[1]: Creation complete after 0s [id=water-name-b]
aws_glue_job.water-name[0]: Creation complete after 0s [id=water-name-a]

Apply complete! Resources: 2 added, 0 changed, 0 destroyed.

No changes. Your infrastructure matches the configuration.

Terraform has compared your real infrastructure against your configuration and found no differences, so no changes are needed.
