重写数据null_data_source为当地人 - 将计数重写为for_each

Question

data "aws_iam_role" "extra_iam_role" {
  count = length(var.s3_permission_extra_roles)
  name  = var.s3_permission_extra_roles[count.index]
}

data "null_data_source" "extra_iam" {
  count = length(var.s3_permission_extra_roles)
  inputs = {
    role_id = "${data.aws_iam_role.extra_iam_role[count.index].unique_id}:*"
  }
}

I want to rewrite that code like this:

data "aws_iam_role" "extra_iam_role" {
  for_each = var.s3_permission_extra_roles
  name  = each.value    
}

# is that correct ?


data "null_data_source" "extra_iam" {
  for_each = var.s3_permission_extra_roles
  inputs = {
    role_id = data.aws_iam_role.extra_iam_role????????
    #what code should be in previous line
  }
}

我在这里一无所知....请帮助

我想摆脱那个 count.index 因为当地人不能使用它...

我不知道如何将 count.index 重写为 for_each 相似性

@kovokilla我相信'var.s3_permission_extra_roles'是类型集，在这种情况下，在第一个代码中，您应该做类似于下面的类似的操作

data "aws_iam_role" "extra_iam_role" {
  for_each = toset(var.s3_permission_extra_roles)
  name  = each.value    
}

，您可以为第二块类似地写一些类似的东西，

data "null_data_source" "extra_iam" {
  for_each = toset(var.s3_permission_extra_roles)
  inputs = {
    role_id = data.aws_iam_role.extra_iam_role[each.key].unique_id
  }
}

请记住以定义您的's3_permission_extra_roles'为类型在您的变量中设置

variable "s3_permission_extra_roles" {
  description = "s3 permission roles"
  default     = ["role1","role2"]
  type        = set(string)
}
