GCP環境向けに作ってみる
０．前提
・すでにGCPアカウントを持っている
・プロジェクト作成済
１．APIの有効化
GCPコンソール画面から
「APIサービス」→「ライブラリ」
以下を検索し有効化されていればOK。されてなければ有効化
Google Compute Engine API
２． credentialファイル の準備
「APIとサービス」→「認証情報」→「認証情報を作成」→「サービスアカウントキー
以下の内容で作成
作成したものをローカルにダウンロードしてterraform実行サーバにアップする
３．環境変数追加
その前に先程のcredentialファイルを作業フォルダに移動
認証情報を追加する
export GOOGLE_CLOUD_KEYFILE_JSON={{credentialファイルへのパス}}４．コードを書く
[root@terraform terraform_gcp]# vi instance.tf
provider "google" {
project = "{{作成するプロジェクトID}}"
region = "us-central1"
zone = "us-central1-c"
}
resource "google_compute_instance" "vm_instance" {
name = "terraform-instance"
machine_type = "f1-micro"
boot_disk {
initialize_params {
image = "debian-cloud/debian-9"
}
}
network_interface {
# A default network is created for all GCP projects
network = "${google_compute_network.vpc_network.self_link}"
access_config = {
}
}
}
resource "google_compute_network" "vpc_network" {
name = "terraform-network"
auto_create_subnetworks = "true"
}５．コードを実行
[root@terraform terraform_gcp]# terraform apply
An execution plan has been generated and is shown below.
Resource actions are indicated with the following symbols:
+ create
Terraform will perform the following actions:

Do you want to perform these actions?
Terraform will perform the actions described above.
Only 'yes' will be accepted to approve.

Apply complete! Resources: 2 added, 0 changed, 0 destroyed.とりあえずインスタンスを作成するまでは完了。
credentialファイルの作成後サーバにコピペしたときにコピペミスしててエラーとなってたのにはまった。。
ちゃんとアップロードしないと失敗の原因になる（白目
触りも触り程度の内容なので次回はもっと難しいことしたい
