无法读取数据块中的文件

Question

我正在以下列方式生成一个文件

resource "null_resource" "clone_manifest_argocd" {
  provisioner "local-exec" {
    command = <<EOT
      echo "Clone ArgoCD main branch"
      git clone https://${var.gitlab_user}:${var.gitlab_token}@gitlab.com/org/k8s-argocd.git
      echo "Generate kustomize files for ${var.argocd_overlay} env"
      kubectl kustomize k8s-argocd/overlays/${var.argocd_overlay}/ -o /tmp/${var.argocd_overlay}.yaml
      cat /tmp/${var.argocd_overlay}.yaml
    EOT
  }
  triggers = {
    always = timestamp()
  }
}

文件总是被正确地创建和填充。

...
null_resource.clone_manifest_argocd (local-exec):     app.kubernetes.io/part-of: argocd-applicationset
null_resource.clone_manifest_argocd (local-exec):   name: argocd-applicationset-controller
null_resource.clone_manifest_argocd (local-exec): ---
null_resource.clone_manifest_argocd (local-exec): apiVersion: v1
null_resource.clone_manifest_argocd (local-exec): kind: ServiceAccount
null_resource.clone_manifest_argocd (local-exec): metadata:
null_resource.clone_manifest_argocd (local-exec):   labels:
null_resource.clone_manifest_argocd (local-exec):     app.kubernetes.io/component: dex-server
null_resource.clone_manifest_argocd (local-exec):     app.kubernetes.io/name: argocd-dex-server
null_resource.clone_manifest_argocd (local-exec):     app.kubernetes.io/part-of: argocd
null_resource.clone_manifest_argocd (local-exec):   name: argocd-dex-server
null_resource.clone_manifest_argocd (local-exec): ---

现在，为了部署它，我想使用kubectl提供程序。我已经设置好了

provider "kubectl" {
  load_config_file       = false
  host                   = module.eks.cluster_endpoint
  cluster_ca_certificate = base64decode(module.eks.cluster_certificate_authority_data)
  token                  = data.aws_eks_cluster_auth.eks_auth.token
}

我尝试了以下方法来获取YAML文件并部署它

data "kubectl_file_documents" "files" {
    content = file("/tmp/${var.argocd_overlay}")
}

resource "kubectl_manifest" "test" {
    for_each  = data.kubectl_file_documents.files.manifests
    yaml_body = each.value
}

我也尝试过

data "template_file" "files" {
  template = file("/tmp/${var.argocd_overlay}.yaml")
}

resource "kubectl_manifest" "public_alb" {
  yaml_body = data.template_file.files.rendered
}

但不管是哪种情况，我

│ Error: Invalid function argument
│ 
│   on main.tf line 161, in data "template_file" "public_alb":
│  161:   template = file("/tmp/${var.argocd_overlay}.yaml")
│     ├────────────────
│     │ var.argocd_overlay is "dev"
│ 
│ Invalid value for "path" parameter: no file exists at "/tmp/dev.yaml"; this
│ function works only with files that are distributed as part of the

│ that resource.

这里有我缺少的东西吗？

根据Terraform 文件功能文档：

此函数只能用于Terraform运行开始时磁盘上已经存在的文件。函数不参与依赖关系图，因此该函数不能与Terraform操作期间动态生成的文件一起使用。

您可能希望尝试库口化提供者，而不是动态创建文件。
