• 開発環境・本番環境の２つを作成します。

$ sh bin/terraform_aws.sh workspace new dev

コマンドログ

Created and switched to workspace "dev"!

You're now on a new, empty workspace. Workspaces isolate their state,
so if you run "terraform plan" Terraform will not see any existing state
for this configuration.`

コマンドログ

Created and switched to workspace "prod"!

You're now on a new, empty workspace. Workspaces isolate their state,
