Access control with IAM

This page describes the access control options that are available to you in Eventarc.

Overview

Eventarc uses Identity and Access Management (IAM) for access control.

For an introduction to IAM and its features, see the IAM overview. To learn how to grant and revoke access, see Manage access to projects, folders, and organizations.

For lists of the permissions and roles that Eventarc supports, see the following sections.

Eventarc service agent

Some Google Cloud services have service agents that allow the service to access your resources if granted the appropriate permissions. If an API requires a service agent, then Google Cloud creates the service agent at some point after you activate and use the API.

Eventarc uses a provisioning model that creates its service agent only when first needed—for example, when you create an Eventarc resource for the first time—and not when the API is initially enabled. Provisioning the service agent and propagating the changes through the system can take several minutes. For more information about this delay, see Permission denied while using Eventarc service agent.

Enable the Eventarc APIs

To view and assign IAM roles for Eventarc, you must enable the Eventarc APIs for your project. You won't be able to see the Eventarc roles in the Google Cloud console until you enable the APIs.

Enable the Eventarc API and the Eventarc Publishing API:

Console

Roles required to enable APIs

To enable APIs, you need the Service Usage Admin IAM role (roles/serviceusage.serviceUsageAdmin), which contains the serviceusage.services.enable permission. Learn how to grant roles.

Enable the APIs

gcloud

Roles required to enable APIs

To enable APIs, you need the Service Usage Admin IAM role (roles/serviceusage.serviceUsageAdmin), which contains the serviceusage.services.enable permission. Learn how to grant roles. 

gcloud services enable eventarc.googleapis.com eventarcpublishing.googleapis.com

Predefined roles

The following table lists the Eventarc predefined IAM roles with a corresponding list of all the permissions each role includes.

The predefined roles address most typical use cases. If your use case isn't covered by the predefined roles, you can create an IAM custom role.
