开始前的准备工作

本页介绍了如何创建 Google Cloud 项目、启用 Transcoder API、创建身份验证凭据，以及向您的账号授予一个或多个 IAM 角色。本页面还介绍了如何设置 Cloud Storage 存储桶以保存转码器作业输出文件。

创建项目

1. Sign in to your Google Cloud account. If you're new to Google Cloud, create an account to evaluate how our products perform in real-world scenarios. New customers also get $300 in free credits to run, test, and deploy workloads.

2. Install the Google Cloud CLI.

3. If you're using an external identity provider (IdP), you must first sign in to the gcloud CLI with your federated identity.

4. To initialize the gcloud CLI, run the following command:

   gcloud init

5. Create or select a Google Cloud project.

   Note: If you don't plan to keep the resources that you create in this procedure, create a project instead of selecting an existing project. After you finish these steps, you can delete the project, removing all resources associated with the project.

   • Create a Google Cloud project:

     gcloud projects create PROJECT_ID

     Replace PROJECT_ID with a name for the Google Cloud project you are creating.

   • Select the Google Cloud project that you created:

     gcloud config set project PROJECT_ID

     Replace PROJECT_ID with your Google Cloud project name.

6. Make sure that billing is enabled for your Google Cloud project.

7. Enable the Transcoder API:

   gcloud services enable transcoder.googleapis.com

8. Create local authentication credentials for your user account:

   gcloud auth application-default login

   If an authentication error is returned, and you are using an external identity provider (IdP), confirm that you have signed in to the gcloud CLI with your federated identity.

9. Grant roles to your user account. Run the following command once for each of the following IAM roles: roles/transcoder.admin

   gcloud projects add-iam-policy-binding PROJECT_ID --member="user:USER_IDENTIFIER" --role=ROLE

   • Replace PROJECT_ID with your project ID.

   • Replace USER_IDENTIFIER with the identifier for your user account. For example, user:[e-mail].

   • Replace ROLE with each individual role.

10. Install the Google Cloud CLI.

11. If you're using an external identity provider (IdP), you must first sign in to the gcloud CLI with your federated identity.

12. To initialize the gcloud CLI, run the following command:

    gcloud init

13. Create or select a Google Cloud project.

    Note: If you don't plan to keep the resources that you create in this procedure, create a project instead of selecting an existing project. After you finish these steps, you can delete the project, removing all resources associated with the project.

    • Create a Google Cloud project:

      gcloud projects create PROJECT_ID

      Replace PROJECT_ID with a name for the Google Cloud project you are creating.

    • Select the Google Cloud project that you created:

      gcloud config set project PROJECT_ID

      Replace PROJECT_ID with your Google Cloud project name.

14. Make sure that billing is enabled for your Google Cloud project.

15. Enable the Transcoder API:

    gcloud services enable transcoder.googleapis.com

16. Create local authentication credentials for your user account:

    gcloud auth application-default login

    If an authentication error is returned, and you are using an external identity provider (IdP), confirm that you have signed in to the gcloud CLI with your federated identity.

17. Grant roles to your user account. Run the following command once for each of the following IAM roles: roles/transcoder.admin

    gcloud projects add-iam-policy-binding PROJECT_ID --member="user:USER_IDENTIFIER" --role=ROLE

    • Replace PROJECT_ID with your project ID.

    • Replace USER_IDENTIFIER with the identifier for your user account. For example, user:[e-mail].

    • Replace ROLE with each individual role.
注意： 请将 IAM 角色 roles/storage.admin 添加到您的 Google 账号，以便更好地控制项目的 Cloud Storage 存储分区。

创建 Cloud Storage 存储桶

如需保存转码作业输出文件，请在 Transcoder API 作业所在的位置创建一个 Cloud Storage 存储桶。如需了解详情，请参阅“位置”页面的媒体资源部分。

1. In the Google Cloud console, go to the Cloud Storage Buckets page.

   Go to Buckets

2. Click Create.
3. On the Create a bucket page, enter your bucket information. To go to the next step, click Continue.
   1. For Name your bucket, enter a unique bucket name. Don't include sensitive information in the bucket name, because the bucket namespace is global and publicly visible.
   2. In the Choose where to store your data section, do the following:
      1. Select a Location type.
      2. Choose a location where your bucket's data is permanently stored from the Location type drop-down menu.
         • If you select the dual-region location type, you can also choose to enable turbo replication by using the relevant checkbox.
      3. To set up cross-bucket replication, select Add cross-bucket replication via Storage Transfer Service and follow these steps:

         Set up cross-bucket replication

         1. In the Bucket menu, select a bucket.

         2. In the Replication settings section, click Configure to configure settings for the replication job.

            The Configure cross-bucket replication pane appears.

            • To filter objects to replicate by object name prefix, enter a prefix that you want to include or exclude objects from, then click Add a prefix.
            • To set a storage class for the replicated objects, select a storage class from the Storage class menu. If you skip this step, the replicated objects will use the destination bucket's storage class by default.
            • Click Done.
   3. In the Choose how to store your data section, do the following:
      1. In the Set a default class section, select the following: Standard.
      2. To enable hierarchical namespace, in the Optimize storage for data-intensive workloads section, select Enable hierarchical namespace on this bucket.
         Note: You cannot enable hierarchical namespace in existing buckets.
   4. In the Choose how to control access to objects section, select whether or not your bucket enforces public access prevention, and select an access control method for your bucket's objects.
      Note: You cannot change the Prevent public access setting if this setting is enforced at an organization policy.
   5. In the Choose how to protect object data section, do the following:
      • Select any of the options under Data protection that you want to set for your bucket.
        • To enable soft delete, click the Soft delete policy (For data recovery) checkbox, and specify the number of days you want to retain objects after deletion.
        • To set Object Versioning, click the Object versioning (For version control) checkbox, and specify the maximum number of versions per object and the number of days after which the noncurrent versions expire.
        • To enable the retention policy on objects and buckets, click the Retention (For compliance) checkbox, and then do the following:
          • To enable Object Retention Lock, click the Enable object retention checkbox.
          • To enable Bucket Lock, click the Set bucket retention policy checkbox, and choose a unit of time and a length of time for your retention period.
      • To choose how your object data will be encrypted, expand the Data encryption section (), and select a Data encryption method.
4. Click Create.
5. 点击创建文件夹并输入名称，以创建一个用于保存已编码的视频输出的文件夹。
