删除和导出作业

本页面介绍了如何删除和导出批量作业。

删除作业后，您在查看作业及其任务时显示的作业详细信息和历史记录将从 Batch 中移除。如果要移除与作业关联的所有信息和资源，您还需要从已启用的任何其他 Google Cloud 产品（例如 Pub/Sub 主题、BigQuery 表或 Cloud Logging 日志）中删除内容。

Google Cloud 会在作业失败或成功 60 天后自动删除作业。在自动删除作业之前，您可以选择执行以下任一操作：

  • 导出作业：如果希望将作业中的信息保留 60 天以上，可以执行以下任一操作：

  • 删除作业：如本文档中所述，如果您已准备好将作业从项目的作业列表中移除，并且不再需要该作业的历史记录，则可以手动将其删除。如果您在作业运行之前或运行期间将其删除，则该作业会被取消。

准备工作

删除作业

您可以使用 Google Cloud 控制台、gcloud CLI、Batch API、Go、Java、Node.js、Python 或 C++ 删除作业。

控制台

如需使用 Google Cloud 控制台删除作业，请执行以下操作：

  1. 在 Google Cloud 控制台中，前往作业列表页面。

    转到“作业”列表

  2. 点击您创建的作业的名称。作业详情页面随即打开。

  3. 点击 删除。

  4. 在要删除批量作业吗？对话框中，输入 Delete。

  5. 点击删除。

    作业列表页面会显示作业已被删除。

gcloud

如需使用 gcloud CLI 删除作业，请使用 gcloud batch jobs delete 命令。

gcloud batch jobs delete JOB_NAME --location LOCATION

替换以下内容：

  • JOB_NAME：作业的名称。
  • LOCATION：作业的位置。

API

如需使用 Batch API 删除作业，请使用 jobs.delete 方法：

DELETE https://batch.googleapis.com/v1/projects/PROJECT_ID/locations/LOCATION/jobs/JOB_NAME

替换以下内容：

  • PROJECT_ID：您的项目 ID。
  • LOCATION：作业的位置。
  • JOB_NAME：作业的名称。

	ctx := context.Background()
	batchClient, err := batch.NewClient(ctx)
	if err != nil {
		return fmt.Errorf("NewClient: %w", err)
	}
	defer batchClient.Close()

	req := &batchpb.DeleteJobRequest{
		Name: fmt.Sprintf("projects/%s/locations/%s/jobs/%s", projectID, region, jobName),
	}

	response, err := batchClient.DeleteJob(ctx, req)
	if err != nil {
		return fmt.Errorf("unable to delete job: %w", err)
	}

	fmt.Fprintf(w, "Job deleted: %v\n", response)

	return nil
