このガイドでは、gcloud functions コマンドで作成した関数を管理する方法とデタッチする方法について説明します。gcloud run コマンドで作成した関数を管理する方法については、Cloud Run サービスを管理するをご覧ください。
Cloud Functions v2 API を使用して作成された関数（gcloud functions、REST API、Terraform など）は、Cloud Run Admin API と Cloud Functions v2 API で管理できます。たとえば、既存の関数を更新するには、gcloud functions コマンドまたは gcloud run コマンドを使用します。
gcloud run deploy FUNCTION_NAME \
--source= . \
--function=ENTRYPOINT
--base-image=google-22-full/nodejs22
デタッチ
gcloud functions detach コマンドを使用すると、Cloud Functions v2 関数を既存の API 環境からデタッチできます。関数をデタッチすると、Cloud Run Admin API を使用してのみ関数を管理できます。これは、ワークロードを Assured Workloads の run.googleapis.com API 境界内に維持する必要がある場合や、ワークロードで Cloud Run SKU を使用するようにする場合に必要になることがあります。
関数のデタッチを準備をする
関数をデタッチする準備をする際は、次の点を考慮してください。
デタッチ オペレーションは元に戻せません。
デタッチ オペレーションは、Cloud Run functions（第 1 世代）には適用できません。
Google Cloud コンソール、Google Cloud CLI、Terraform を使用して Cloud Run に関数をデプロイする方法を確認してください。
HTTP 関数には、割り当てられた URL が保持されます。
イベント ドリブン関数に接続されているトリガーは保持されます。
トリガーは run.googleapis.com API から直接管理できません。Eventarc または Pub/Sub のトリガー管理ガイドをよく理解してください。

To learn how to manage a function that was\ncreated with the `gcloud run` command, see [Manage Cloud Run services](/run/docs/managing/services).\n| **Note:** If you created a Cloud Run function using `gcloud run` commands or the Cloud Run Admin API, you can't manage that function with `gcloud functions` commands or the Cloud Functions v2 API.\n\nFunctions created using the [Cloud Functions v2 API](/functions/docs/apis)\n(for example, by using `gcloud functions`, the REST API, or Terraform) can be\nmanaged with the [Cloud Run Admin API](/run/docs/reference/cloud-run-admin-api-overview)\nas well as the Cloud Functions v2 API. For example, you can update an\nexisting function using either `gcloud functions` or `gcloud run` commands: \n\n### gcloud functions\n\n gcloud functions deploy \u003cvar translate=\"no\"\u003eFUNCTION_NAME\u003c/var\u003e \\\n --runtime=nodejs22 \\\n --source= . \\\n --entry-point=\u003cvar translate=\"no\"\u003eENTRYPOINT\u003c/var\u003e\n --trigger-http\n\n### gcloud run\n\n gcloud run deploy \u003cvar translate=\"no\"\u003eFUNCTION_NAME\u003c/var\u003e \\\n --source= . \\\n --function=\u003cvar translate=\"no\"\u003eENTRYPOINT\u003c/var\u003e\n --base-image=google-22-full/nodejs22\n\nDetach\n------\n\nThe [`gcloud functions detach`](/sdk/gcloud/reference/functions/detach)\ncommand lets you detach a Cloud Functions v2 function from its existing\nAPI environment. After you detach a function, you can only manage it using the\nCloud Run Admin API. You might want to do this if your workloads need to stay\nwithin the `run.googleapis.com` API boundary for\n[Assured Workloads](/assured-workloads/docs/overview), or to ensure\nthat your workloads use the [Cloud Run SKU](/skus/sku-groups/cloud-run).\n\n### Prepare your function for detach\n\nWhen preparing to detach your function, consider the following:\n\n- The detach operation is not reversible.\n- The detach operation cannot be applied to Cloud Run functions (1st gen).\n- Familiarize yourself with how to [deploy functions in Cloud Run](/run/docs/deploy-functions) using the Google Cloud console, Google Cloud CLI, and Terraform.\n- HTTP functions will retain their assigned URLs.\n- Triggers attached to event-driven functions will be retained.\n- Triggers cannot be managed through the `run.googleapis.com` API directly. Be sure to familiarize yourself with the trigger management guides for [Eventarc](/eventarc/docs) or [Pub/Sub](/pubsub/docs/overview).\n- Disabling [retry on failure](/functions/docs/bestpractices/retries#event_driven_functions_created_with_v2_api) is not a supported feature on Cloud Run.\n - During the detach operation, Cloud Run functions modifies the triggers attached to functions configured with [no retry on failure](/functions/docs/bestpractices/retries#event_driven_functions_created_with_v2_api), to ensure that the underlying Pub/Sub topic makes a maximum of five delivery attempts. When the detach operation is completed, a [dead letter queue](/pubsub/docs/handling-failures#how_dead_letter_topics_work) topic stores the undelivered messages, which you can retrieve by creating a new subscription to the dead letter queue.\n- When a function is successfully detached, a new Cloud Run revision is created. Starting from that revision onwards, the function will be billed using the [Cloud Run SKU](/skus/sku-groups/cloud-run).\n\n### Detach your function\n\nYou can detach your function using the following command: \n\n gcloud functions detach \u003cvar translate=\"no\"\u003eFUNCTION_NAME\u003c/var\u003e\n\nReplace \u003cvar translate=\"no\"\u003eFUNCTION_NAME\u003c/var\u003e with the name of your function."]]
