使用 Terraform 部署数据流

Deploy a Dataflow with Terraform

我正在尝试在 GCloud 中使用 Terraform 部署数据流模板。

有几个教程包含一些 terraform 代码。有2个options:Use模块如下link or use resource like the following link

对于这两个选项,我都出现以下错误:

Error: googleapi: got HTTP response code 502 with body: <!DOCTYPE html>

  on .terraform\modules\dataflow-job\terraform-google-modules-terraform-google-dataflow-722fc1d\main.tf line 17, in resource "google_dataflow_job" "dataflow_job":
  17: resource "google_dataflow_job" "dataflow_job" {

我已经尝试从我的本地计算机 运行ning 以及 GCP 内的云端 shell。

问题应该出在数据流模块中,因为我还尝试创建其他资源,如存储桶和计算引擎,并且没有任何问题。

在我 运行 terraform 脚本之前,数据流模板存储在存储桶中。

Terraform 版本:0.12.19

代码:

main.tf

variable "project_id" {}
<...>


provider "google" {
  version = "~> 2.8.0"
  region  = var.region
}

resource "google_dataflow_job" "dataflow_job" {
  project               = var.project_id
  region                = var.region
  zone                  = "${var.region}-a"
  name                  = var.project_name
  on_delete             = "cancel"
  max_workers           = var.max_workers
  template_gcs_path     = var.template_location
  temp_gcs_location     = "gs://${var.gcs_location}/tmp_dir"
  service_account_email = var.controller_service_account_email
  parameters = {
    inputPubSub       = var.input_PubSub_subscription
    outputPubSub      = var.output_PubSub_subscription
  }
  machine_type     = var.machine_type
}

terraform.tfvars

<...>
template_location = "gs://www/zzz/template"
gcs_location= "gs://www/yyy"
<...>

为了测试我的代码是否错误,我也直接从link的代码中尝试了同样的错误。

我是否遗漏了要添加到代码中的依赖项?

请注意,您已将 temp_gcs_location 声明为 "gs://${var.gcs_location}/tmp_dir",但随后在 terraform.tvars 中将 gcs_location 设置为 "gs://www/yyy"(因此 gs:// 前缀出现两次)。在任何情况下,该作业都应该启动但无法创建。

我用以下版本做了一个最小的例子:

$ terraform --version
Terraform v0.12.20
+ provider.google v3.5.0

并使用 Google 提供的 word count 模板。我的 main.tf 文件是:

variable "project_id" {
  type        = string
  description = "GCP Project ID."
}
variable "gcs_location" {
  type        = string
  description = "GCS bucket name (no gs:// prefix)."
}

provider "google" {
  project = var.project_id
  region  = "us-central1"
  zone    = "us-central1-c"
}

resource "google_dataflow_job" "wordcount" {
  name              = "wordcount"
  template_gcs_path = "gs://dataflow-templates/latest/Word_Count"
  temp_gcs_location = "gs://${var.gcs_location}/temp"
  parameters = {
    inputFile = "gs://dataflow-samples/shakespeare/kinglear.txt"
    output = "gs://${var.gcs_location}/wordcount/output"
  }
}

df.tfvars(更改为适当的值):

project_id = "PROJECT_ID"
gcs_location = "BUCKET_NAME"

我运行它与:

terraform apply -var-file="df.tvars"

并成功创建作业:

google_dataflow_job.wordcount: Creating...
google_dataflow_job.wordcount: Creation complete after 3s [id=2020-01-27_...]

如果有帮助请告诉我。
