IAM 角色可見度
部分 IAM 角色只有在相關聯的服務於 Google Cloud 專案中啟用時才會顯示。舉例來說，roles/compute.admin 角色只有在專案已啟用 compute.googleapis.com API 時才會顯示。如要瞭解如何列出可在專案中授予的角色，請參閱「檢視可針對資源授予的角色」一文。
預設啟用的服務
使用 Google Cloud 控制台或 Google Cloud CLI 建立 Google Cloud 專案時，系統會依預設啟用下列 API 與服務：

Enabling APIs and services in a Google Cloud project,\nresults in the following changes:\n\n- Associates them with the project.\n- Adds monitoring pages in the Google Cloud console.\n- Enables billing for the APIs and services if billing is enabled for the project.\n- In some cases, [Identity and Access Management](/iam) roles only become visible when you enable the associated service.\n\nCalling a service\n-----------------\n\nThe following list outlines the typical high-level requirements for using\nGoogle Cloud APIs and services:\n\n1. A Google Cloud project. For details on creating Google Cloud projects, see [Creating and Managing Projects](/resource-manager/docs/creating-managing-projects).\n2. To enable the service for the project. To learn how to enable APIs and services, see [Enabling and Disabling Services](/service-usage/docs/enable-disable).\n3. Authentication credentials for the enabled service you are using. To learn how to authenticate to a [Cloud API](/apis), see [Authentication methods](/docs/authentication).\n\nThe credentials you use to call Google Cloud APIs and services are\nassociated with the project you use to create them.\n\nIAM role visibility\n-------------------\n\nSome IAM roles are only visible if the associated service is\nenabled in a Google Cloud project. For example, the `roles/compute.admin` role\nis only visible after the `compute.googleapis.com` API is enabled in a project.\nTo learn how to list the available roles to grant in a project, see\n[Viewing the Grantable Roles on Resources](/iam/docs/viewing-grantable-roles).\n\nServices enabled by default\n---------------------------\n\nWhen you create a Google Cloud project using the Google Cloud console or\nGoogle Cloud CLI, the following APIs and services are enabled by default:\n| **Note:** You can disable any of the following services, just like any other service you enable.\n\n- [BigQuery sharing (formerly Analytics Hub)](/analytics-hub)\n- [BigQuery API](/bigquery)\n- [BigQuery Connection API](/bigquery)\n- [BigQuery Data Policy API](/bigquery)\n- [BigQuery Migration API](/bigquery)\n- [BigQuery Reservation API](/bigquery)\n- [BigQuery Storage API](/bigquery)\n- [Cloud Datastore API](/datastore)\n- [Cloud Dataform API](/dataform)\n- [Cloud Dataplex API](/dataplex)\n- [Cloud Logging API](/logging)\n- [Cloud Monitoring API](/monitoring)\n- [Cloud SQL](/sql)\n- [Cloud Storage](/storage)\n- [Cloud Storage API](/storage/docs/json_api/v1)\n- [Cloud Trace API](/trace)\n- [Google Cloud APIs](/apis/docs/overview)\n- [Google Cloud Storage JSON API](/storage/docs/json_api/v1)\n- [Service Management API](/service-management)\n- [Service Usage API](/service-usage)"]]
