今日からはじめる Pulumiでカンタンインフラ運用・管理第4回

クリーンアップ作業

今回のハンズオンで構築した環境のクリーンアップ手順です。複数のStackをデプロイしているため、リソースの削除もStackを切り替えて行います。依存関係を考慮して、Stackの削除はcompute.dev > network.dev > secret.devの順に行います。

computeリソースのディレクトリに移動し、Stackを「compute.dev」に切り替えます。

$ pwd
/***/compute

$ pulumi stack select compute.dev

$ pulumi stack ls                
NAME          LAST UPDATE     RESOURCE COUNT  URL
compute.dev*  1 hour ago      8               https://app.pulumi.com/***/pulumi-security/compute.dev
network.dev   36 minutes ago  12              https://app.pulumi.com/***/pulumi-security/network.dev
secret.dev    1 day ago       4               https://app.pulumi.com/***/pulumi-security/secret.dev

Pulumiで作成したリソースを削除する際は「pulumi destroy」コマンドを実行します。コマンド実行後「yes」を選択します。

次に「network.dev」Stackのリソースも削除します。networkリソースのディレクトリに移動し、Stackを「network.dev」に切り替えます。

$ cd ../network 

$ pwd

$ pulumi stack select network.dev

最後に「secret.dev」Stackのリソースも削除します。secretリソースのディレクトリに移動し、Stackを「secret.dev」に切り替えます。

Stackリソースの削除が完了したことでAWSに作成した全てのリソースも削除されましたが、Pulumiのリソースとしてまだ残っているStack自体も削除できます。Stack自体を削除すると「pulumi config」などで設定したStack自体の設定やStackのリソース変更履歴、Stackの設定ファイル「Pulumi.<stack名>.yaml」なども削除されるので、削除の際はご注意ください。Stack削除コマンド「pulumi stack rm」実行後は確認としてStack名の入力が求められるので、削除対象のStack名を入力します。

$ pulumi stack select compute.dev

$ pulumi stack ls

おわりに

今回は、PulumiのSecurityについて解説しました。Pulumi ServiceのようなSaaSを使う場合は、どうしてもSecurityの部分が気になってくるかと思います。本記事を読まれた方は、ある程度安心してPulumiを利用できると思っていただけるかもしれませんが、それでも気になる場合はSelf-Hosted ArchitectureでPulumi Serverを自社の環境にホストするのも1つの手段だと思います。

Securityはとても奥深い話なので、PulumiのSecurityについて更新があれば、またどこかの機会に紹介したいと思います。次回もお楽しみに!
