デフォルトでは、ユーザーは、バッチジョブを実行する Compute Engine VM に、公開イメージまたはユーザーと共有されているカスタム イメージを使用できます。信頼できるイメージのポリシー制約が有効になっておらず、VM OS イメージを制限したくない場合は、この文書を読む必要はありません。
プロジェクト、フォルダ、組織内のすべてのユーザーが、ポリシーまたはセキュリティ要件を満たす承認済みソフトウェアを含む VM を作成するように求める場合は、信頼できるイメージのポリシー制約を有効にします。信頼できるイメージのポリシー制約が有効になっている場合、影響を受けるユーザーは、ジョブの VM OS イメージが許可されていない限り、バッチジョブは実行できません。信頼できるイメージのポリシー制約が有効になっている場合にジョブを作成して実行するには、少なくとも次のいずれかを行います。

Go to the **Organization policies** page.\n\n [Go to Organization policies](https://console.cloud.google.com/iam-admin/orgpolicies/)\n2. From the policies list, click **Define trusted image projects**.\n\n The **Policy details** page opens.\n3. On the **Policy details** page, click edit **Manage Policy** . The **Edit policy**\n page opens.\n\n4. On the **Edit policy** page, select **Customize**.\n\n5. For **Policy enforcement**, select an enforcement option.\n\n6. Click **Add rule**.\n\n7. In the **Policy values** list, you can select whether to add a rule that\n allows access to all unspecified image projects, denies access to all\n unspecified image projects, or specifies a custom set of projects to\n allow or deny access to. To allow all images from Batch,\n do the following:\n\n 1. In the **Policy values** list, select **Custom** . A **Policy type** and **Custom values** field appears.\n 2. In the **Policy type** list, select **Allow**.\n 3. In the **Custom values** field, enter `projects/batch-custom-image`.\n8. To save the rule, click **Done**.\n\n9. To save and apply the organization policy, click **Save**.\n\n### gcloud\n\nThe following example describes how to allow images\nfrom Batch for a specific project:\n\n1. To get the existing policy settings for a project, run the\n [`resource-manager org-policies describe` command](/sdk/gcloud/reference/resource-manager/org-policies/describe):\n\n ```\n gcloud resource-manager org-policies describe \\\n compute.trustedImageProjects --project=PROJECT_ID \\\n --effective \u003e policy.yaml\n ```\n\n Replace \u003cvar translate=\"no\"\u003ePROJECT_ID\u003c/var\u003e with the project ID of the project\n that you want to update.\n2. Open the `policy.yaml` file in a text editor. Then, modify the\n `compute.trustedImageProjects` constraint by adding\n `projects/batch-custom-image` to the `allowedValues` field.\n For example, to allow only VM OS images from Batch\n set the `compute.trustedImageProjects` constraint to the following:\n\n ```\n constraint: constraints/compute.trustedImageProjects\n listPolicy:\n allowedValues:\n - projects//batch-custom-image\n ```\n\n When you have finished editing the `policy.yaml` file, save your changes.\n3. To apply the `policy.yaml` file to your project, use the\n [`resource-manager org-policies set-policy` command](/sdk/gcloud/reference/resource-manager/org-policies/set-policy):\n\n ```\n gcloud resource-manager org-policies set-policy \\\n policy.yaml --project=PROJECT_ID\n ```\n\n Replace \u003cvar translate=\"no\"\u003ePROJECT_ID\u003c/var\u003e with the project ID of the project\n that you want to update.\n\nWhen you finish updating constraints, testing those constraints is\nrecommended to verify that they are working as intended.\n\nWhat's next\n-----------\n\n- Create and run jobs, such as the following:\n - [Create and run a basic job](/batch/docs/create-run-basic-job), which uses a VM OS image from Batch by default.\n - [Create and run a job that uses a specific VM OS image](/batch/docs/specify-vm-os-image).\n- Learn more about [VM OS images and boot disks](/batch/docs/vm-os-environment-overview)."]]
