使用 Terraform 部署数据流



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地形代码。有 2 个选项:使用类似以下链接的模块或使用类似以下链接

的资源对于这两个选项,我都有以下错误:

on .terraformmodulesdataflow-jobterraform-google-modules-terraform-google-dataflow-722fc1dmain.tf line 17, in resource "google_dataflow_job" "dataflow_job":
17: resource "google_dataflow_job" "dataflow_job" {

我尝试从本地计算机以及 GCP 中的云外壳运行。

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,并且它可以正常工作。

在我运行地形脚本之前,数据流模板存储在存储桶中。

地形版本: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,我还直接从链接代码和相同的错误中尝试。

我是否缺少任何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,您将gcs_location设置为"gs://www/yyy"(因此gs://前缀出现两次(。在任何情况下,作业都应启动,但随后无法创建。

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

并使用谷歌提供的字数统计模板。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(使用适当的值进行更改(:

project_id = "PROJECT_ID"
gcs_location = "BUCKET_NAME"

我用:

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

并且作业已成功创建:

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

让我知道这是否有帮助。
