【中文标题】Terraform k8sraw 提供程序错误：产生了一个意外的新值，但在创建模板时现在不存在

【英文标题】：Terraform k8sraw provider error: produced an unexpected new value for was present, but now absent while template is created

【问题描述】：

我们的 terraform 部署最近失败，出现错误：

Error: Provider produced inconsistent result after apply
When applying changes to k8sraw_yaml.test-template, provider
"registry.terraform.io/-/k8sraw" produced an unexpected new value for was
present, but now absent.
This is a bug in the provider, which should be reported in the provider's own
issue tracker.

k8sraw 提供者不是 terraform 官方提供者，它是从 github 获得的，该项目的 url 位于： https://github.com/nabancard/terraform-provider-kubernetes-yaml

提供程序在很长一段时间内都可以正常工作，直到一周前，我们发现它从 2021 年 10 月 15 日开始出现上述错误。

我们使用的 terraform 版本是 0.12.24

感谢帮助。

我有使用 k8sraw 的示例代码：

  backend "s3" 


provider "local" 
  version = "~> 1.4"

  version = ">=1.6.2"
  config_path = "~/.kube/kube.conf"


provider "k8sraw" 
data "template_file" "test-template" 
  template = "$file("$path.module/templates/test-template.yml.tpl")"

  vars = 
    workflow_template_name     = var.template_ref_name,
    k8s_namespace              = var.k8s_namespace,
  


resource "k8sraw_yaml" "test-template" 
  yaml_body = data.template_file.test-template.rendered


data "template_file" "workflow" 
  template = "$file("$path.module/templates/test-workflow.yml.tpl")"
  vars = 
    test_template_ref = var.template_ref_name
    service_account = "$var.service_account",

  content  = "$data.template_file.test-template.rendered"

地形命令：

  $ terraform init -force-copy -upgrade  -backend-config="backends/backend.tfvars"
  $ terraform workspace select testdeployment || terraform workspace new testdeployment
  $ terraform plan  -var-file="vars/test.tfvars"
  $ terraform apply -auto-approve -var-file="vars/test.tfvars"

【参考方案1】：

我在其他网站上找到了答案，所以答案是将terraform升级到0.14.9或更高，然后将k8sraw替换为kubernetes_manifest。

具体如何更改，请参考以下链接： https://registry.terraform.io/providers/hashicorp/kubernetes/latest/docs/resources/manifest 和 https://www.terraform.io/docs/language/functions/yamldecode.html

干杯！
