Access control with IAM

Advanced Standard

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 using allow policies, see Manage access to projects, folders, and organizations.

• To control publishing access in Eventarc Advanced using access policies, see Control publishing access.

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.

Console

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.

In the Google Cloud console, on the project selector page, select or create a Google Cloud project.

Roles required to select or create a project

• Select a project: Selecting a project doesn't require a specific IAM role—you can select any project that you've been granted a role on.
• Create a project: To create a project, you need the Project Creator role (roles/resourcemanager.projectCreator), which contains the resourcemanager.projects.create permission. Learn how to grant roles.

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.

Go to project selector

Verify that billing is enabled for your Google Cloud project.

Enable the Eventarc and Eventarc Publishing APIs.

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.

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.

Project-level IAM management

At the project level, you can grant, change, and revoke IAM roles using the Google Cloud console, the IAM API, or the Google Cloud CLI. For instructions, see Manage access to projects, folders, and organizations.
