タスクのコスト管理などにタグをつけたい場合があるが、デフォルトではタグが付かないので設定を入れる必要がある。
※こんな感じ
やること
TerraformでECS(Fargate)環境を作成し、サービスとタスク定義にタグをつけ、それぞれ伝搬させてタスクにタグが伝搬されるか確認する。
実践！
１．下記を参考にECS環境を作成する。
amegaeru.hatenablog.jp
２．タグ伝搬設定
２－１．terraformに下記を追加
### TaskDefinitionに下記を追加 tags = { "Name" = "example-task" "Environment" = "Production" } ### Serviceに下記を追加 tags = { ServiceTagKey = "ServiceTagValue" } enable_ecs_managed_tags = true propagate_tags = "TASK_DEFINITION"
２－２．適用
# terraform apply
３．タスク更新
３－１．[ECS] - [Cluster] - [test_my_cluster] を押下
３－２．[test_my_service]を押下
３－３．[サービスを更新]を押下
３－４．[新しいデプロイを強制]にチェック
３－５．[更新]を押下
４．タグ確認
４－１．[タスク]タブを選択し、新たに作成されたタスクを選択
４－２．タスク定義のタグが伝搬されていることを確認
５．サービスからの伝搬に変更しタグ確認
５－１．Terraformコードを下記に変更
変更前）propagate_tags = "TASK_DEFINITION" 変更後）propagate_tags = "SERVICE"
５－２．適用
# terraform
５－３．項番３を実施
５－４．項番４を実施し、サービスのタグが伝搬されていることを確認
６．設定確認
※GUIでは確認できないので、CLIで確認する
# aws ecs describe-services --cluster test_my_cluster --service test_my_service

感想
ECS奥が深いねぇ(´Д｀)
