第一次接觸terraform來管理GCP

 希望能夠透過terraform來加速佈建雲端服務的效率

1. 安裝terraform

(terraform只是一個執行檔案)

到https://www.terraform.io/downloads.html 下載壓縮檔案
解壓縮到機器上的/usr/local/bin就可以直接使用

2.建立第一個 tf配置檔案

 a.從GCP建立Account Service , 並下載金鑰檔案(json格式),rename成account.json
 b.配置Google Cloud provider設定
(project 這邊是project id)

 provider "google" {
  credentials = file("account.json")
  project = "ab-xx-xxxx"
  region  = "asia-east1"
}

3. 完善tf設定檔案,並在台灣節點建立一台vm , 配置如下

file - 1.tf

  
  provider "google" {
  credentials = file("account.json")
  project = "ab-xx-xxxx
  region  = "asia-east1"
}

resource "google_compute_instance" "vm_instance" {
name         = "terraform-instance"
machine_type = "n1-standard-1"
zone         = "asia-east1-c"

boot_disk {
initialize_params {
image = "centos-cloud/centos-7"
 }
}

network_interface {

    # A default network is created for all GCP projects
 network       = "default"
subnetwork    = "default"
 }
}

4.啟動/刪除資源從tf檔案 ---- 好處是資源新增刪除都不會漏掉
(金鑰和tf檔案都要放在同一層)

啟動
terraform init

刪除
terraform destroy
