Access control with IAM

This page provides supplemental information for using Identity and Access Management (IAM) roles to set access controls at a project level, to determine the level of access to your Google Cloud project and functions created using gcloud functions commands or the Cloud Functions v2 API.

If you've created or deployed functions using Cloud Run, see Access control with IAM and Cloud Run roles for a detailed description of Cloud Run predefined roles, controlling access to individual services, making a service public, or configuring organization policy for the Cloud Run invoker IAM.

Access control for users

Add users as team members to your project and grant them roles using IAM.

Cloud Run functions supports the following roles:

Access control for service accounts

A service account is a special type of Google Cloud account that acts as an identity for a non-human user that needs to authenticate and be authorized to access data and perform various actions. Some of these accounts are created and managed by Google itself and are known as service agents.

The following service accounts are used for Cloud Run functions:

Name Member ID Role
Compute Engine default service account PROJECT_NUMBER-compute@developer.gserviceaccount.com Editor
Google Cloud Functions Service Agent service-PROJECT_NUMBER@gcf-admin-robot.iam.gserviceaccount.com Google Cloud Functions Service Agent
Legacy Cloud Build service account1 PROJECT_NUMBER@cloudbuild.gserviceaccount.com Cloud Build Service Account
Cloud Build Service Account service-PROJECT_NUMBER@gcp-sa-cloudbuild.iam.gserviceaccount.com Cloud Build Service Agent
Google Container Registry Service Agent service-PROJECT_NUMBER@containerregistry.iam.gserviceaccount.com Container Registry Service Agent
Artifact Registry Service Agent service-PROJECT_NUMBER@gcp-sa-artifactregistry.iam.gserviceaccount.com Artifact Registry Service Agent

Runtime service accounts

At runtime, Cloud Run functions defaults to using the Compute Engine default service account (PROJECT_NUMBER-compute@developer.gserviceaccount.com), which also has the Editor role on the project. You can change the roles of these service accounts to limit or extend the permissions for your running functions. You can also change which service account is used by avoiding the default service account when configuring service identity.

To learn more about service accounts, see the service accounts documentation.

Administrative service accounts

To perform administrative actions on your project during the creation, updating, or deletion of functions, all projects in Cloud Run functions require the Google Cloud Functions Service Agent service account (service-PROJECT_NUMBER@gcf-admin-robot.iam.gserviceaccount.com).

In addition, all runtimes carry out container image building and storage within your project. To support this, you also need to provision the following:

These service accounts should have the roles listed in the earlier table.

Google Cloud Functions Service Agent service account

By default, the Google Cloud Functions Service Agent service account (service-PROJECT_NUMBER@gcf-admin-robot.iam.gserviceaccount.com has the cloudfunctions.serviceAgent role on your project.
