Ansibleを使用して、CentOS 7にTerraformとterraform-provider-openstackをインストールする

Last updated at Posted at 2019-11-24

Ansibleを使用して、CentOS 7にTerraformとterraform-provider-openstackをインストールする

Terraformとは何ぞや？という方は下記を一読いただければと思います。

作成するに至った経緯

  • Terraformとterraform-provider-openstackを手動でインストールするのが面倒なので、自動化したかったため。
  • Terraformを実行するために必要な各ディレクトリ/ファイルの作成を手動で行うのが面倒だったため。

OpenStackを採用した理由

  • AWSアカウントを作成しなくてもよいため
  • 無料で触れるため
  • 触り慣れているため

OpenStackのインストール方法については、本記事の最後のほうに記述しております。

対象者

  • CentOS 7 に、Terraformをインストールしたい方
  • OpenStack環境を使用して、Terraform のハンズオンをやってみたい方

前提条件

  • Ansible、OpenStackはインストール済みであるとする
  • config、inventoryの設定は完了済みであるとする
  • 鍵生成、鍵交換、疎通確認は完了済みであるとする
  • proxy環境下ではないものとする

実行環境

# cat /etc/redhat-release 
CentOS Linux release 7.7.1908 (Core)
# ansible --version
ansible 2.9.1
  config file = /etc/ansible/ansible.cfg
  configured module search path = [u'/root/.ansible/plugins/modules', u'/usr/share/ansible/plugins/modules']
  ansible python module location = /usr/lib/python2.7/site-packages/ansible
  executable location = /bin/ansible
  python version = 2.7.5 (default, Aug  7 2019, 00:51:29) [GCC 4.8.5 20150623 (Red Hat 4.8.5-39)]

本playbookで行っていることの概要

  • Terraformのインストールに必要なパッケージのインストール
  • Terraform, terraform-provider-openstackのインストール
  • ディレクトリの作成
  • variables.tfファイルの作成
  • config.tfvarsファイルの作成
  • main.tfファイルの作成

Terraformのディレクトリ構成について

etc
┗ terraform
    ┗ create_instance
        ┣ variables.tf    # 変数について記述したファイル
        ┣ config.tfvars   # OpenStack環境について記述したファイル
        ┗ main.tf         # 実際に設定を流し込むファイル

Terraformのファイル作成に必要な情報の収集

config.tfvarsとmain.tfファイルに必要な情報をあらかじめ取得しておきます。★印を振っている項目が必要な情報となります。

ansible-playbookの実行により、Terraformのインストールと、Terraform実行に必要なファイルの作成が完了いたしました。まずは、Terraformのバージョン確認をしてみましょう。

Terraformのバージョン確認

[root@localhost playbook(keystone_admin)]# terraform -v
Terraform v0.11.13

Your version of Terraform is out of date! The latest version
is 0.12.16. You can update by downloading from www.terraform.io/downloads.html

v0.11.13がインストールされていることが確認できました。それでは、ディレクトリを変更して、Terraformの初期化をしてみましょう。

Terraformの初期化

[root@localhost playbook(keystone_admin)]# cd /etc/terraform/create_instance/
[root@localhost create_instance(keystone_admin)]# ls
config.tfvars  main.tf  variables.tf
[root@localhost create_instance(keystone_admin)]# terraform init

Initializing provider plugins...

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 = "~> 1.24"

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.

初期化に成功しました。ansible-playbookで作成したファイルを使用して、Terraformを実行し、OpenStackにインスタンスを作成してみます。

Terraformの実行

[root@localhost create_instance(keystone_admin)]# terraform apply --var-file=config.tfvars

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:

指定した名前、ネットワーク、イメージ、フレーバーでインスタンスが作成されていることが確認できました。確認ができたので、今後はインスタンスを削除してみましょう。

Terraformで作成したインスタンスを削除する

[root@localhost create_instance(keystone_admin)]# terraform destroy --var-file=config.tfvars
openstack_compute_instance_v2.tr-test-server: Refreshing state... (ID: 2da65d5d-f8ba-4e5a-88cf-43186e981661)

An execution plan has been generated and is shown below.
Resource actions are indicated with the following symbols:
  - destroy

Terraform will perform the following actions:

  - openstack_compute_instance_v2.tr-test-server


Plan: 0 to add, 0 to change, 1 to destroy.

Do you really want to destroy all resources?
  Terraform will destroy all your managed infrastructure, as shown above.
  There is no undo. Only 'yes' will be accepted to confirm.

openstack_compute_instance_v2.tr-test-server: Destruction complete after 11s

Destroy complete! Resources: 1 destroyed.

Terraformで作成したインスタンスが削除されたかを確認する

[root@localhost create_instance(keystone_admin)]# openstack server list

terraform applyコマンドで作成されたインスタンスが削除されていることが確認できました。

まとめ

Ansibleを使用して、CentOS 7にTerraformとterraform-provider-openstackをインストール、Terraformを実行するために必要な各ディレクトリ/ファイルの作成をすることができました。それにより、Terraformのハンズオンをすぐに実行することができました。今度は、Terraformを使用して、ネットワーク、サブネット、ルータの作成を行いたいと思います。
