Local PC(Mac OS) から AIX をPowerSystemsサーバーにTerraformでデプロイする

Local PC からTerraform テンプレートで AIX を PowerSystems 筐体にVM(Virtual Machine)をデプロイを実施した記録です。IaC(Infrastructure as Code) の一環として記載します。

環境

・PowerVC v1.4 on (RHEL v7.5/PowerSystems S824 (Linux on Power)
 以下がPowerVCに登録済み
 ・PowerSystems (S824, VIOS(v3.1 正副構成)
 ・HMC(v8.8.6)
 ・SAN switch
 ・Storage: V7000
 ・使用するネットワーク定義

・Local PC : Mac OS, Movaje

前提

 - PowerVC と Local PC が疎通できるNW環境にあること
 - デプロイに使用するAIXイメージは設定済みであること
- IDなどは一部の特定値は記載上変更しています。

手順

1) Mac 版のTerraform をダウンロード
https://www.terraform.io/downloads.html

2) 任意のディレクトリで圧縮ファイルを解凍

# ls -l
total 192024
-rwxrwxr-x@ 1 user  staff  98302152 Mar 12 18:37 terraform   #<=解凍した terraform コマンド本体

3) main.tf (terraformの実行ファイル)を作成
terraformがある同じディレクトリにmain.tf を作成

# vi main.tf
#(以下を入力)

provider "openstack" {
  user_name   = "root"               #<= 実行ユーザー
  password    = "xxxxxxxx"           #<= PowerVCサーバーのパスワード
  tenant_name = "ibm-default"
  domain_name = "Default"
  auth_url    = "https://<PowerVC_IP_address>:5000/v3/"  #<= PowerVCサーバーのOpenStack KeyStone のendpoint
  insecure    = true
}

resource "openstack_compute_instance_v2" "test" {
  name      = "test0425"                           # <= VM名
  image_id  = "6adc26a0-a625-4162-8114-dxxxxxxxxxx"  # <= イメージID
  flavor_id = "2067438e-4920-4103-822f-exxxxxxxxxx"  # <= 計算テンプレートID

  network {
    uuid = "857a9ad3-7515-4b5c-a152-dxxxxxxxxxx"    # <=  ネットワークID
    name = "test_LAN"
  }
}

(参考) OpenStackコマンドで定義情報確認
・PowerVCサーバーでOpenStackコマンド発行のための変数定義

source /opt/ibm/powervc/powervcrc
export OS_USERNAME=root           #<=OpenStackコマンド実行ユーザー
export OS_PASSWORD="xxxxxxx"      #<=ユーザーのパスワードを指定

・エンドポイント (KeyStone) を確認

4) terraform init
terraform plugin を導入します。

# ./terraform init

Initializing provider plugins...
- Checking for available provider plugins on https://releases.hashicorp.com...
- Downloading plugin for provider "openstack" (1.17.0)...

The following providers do not have any version constraints in configuration,
so the latest version was installed.

To prevent automatic upgrades to new major versions that may contain breaking
changes, it is recommended to add version = "..." constraints to the
corresponding provider blocks in configuration, with the constraint strings
suggested below.

* provider.openstack: version = "~> 1.17"

Terraform has been successfully initialized!

You may now begin working with Terraform. Try running "terraform plan" to see
any changes that are required for your infrastructure. All Terraform commands
should now work.

If you ever set or change modules or backend configuration for Terraform,
rerun this command to reinitialize your working directory. If you forget, other
commands will detect it and remind you to do so if necessary.
