AWS環境をTerraformで作るときはS3 Backendを活用しましょう

AWS環境をTerraformで作るときはS3 Backendを活用しましょう

Terraformはtfstateファイルで構成情報を管理しているが、 単純にtfstateファイルをgit等で共有すると他の人が構成変更 (terrafrom apply)している最中に別に作業を実行したり出来る。

そういうときに良く競合してあるべきリソースが削除されたりするが Terraform Backend S3 + DynamoDB Lockを利用することで、自動的に ロックしながら最新状態を共有することが可能となる。
