Manage GCP BigQuery Data Policy IAM Bindings

The gcp:bigquerydatapolicy/dataPolicyIamBinding:DataPolicyIamBinding resource, part of the Pulumi GCP provider, manages IAM role bindings for BigQuery data policies by granting a specific role to a list of members. This guide focuses on two capabilities: granting roles to multiple members and adding individual members incrementally.

IAM bindings reference existing data policies and require valid member identities such as users, service accounts, groups, or domains. The examples are intentionally small. Combine them with your own data policy resources and identity management workflows.

Grant a role to multiple members at once

Teams managing data policies often need to grant the same role to multiple users or service accounts simultaneously, such as giving viewer access to an analytics team.

import * as pulumi from "@pulumi/pulumi";
import * as gcp from "@pulumi/gcp";

const binding = new gcp.bigquerydatapolicy.DataPolicyIamBinding("binding", {
    project: dataPolicy.project,
    location: dataPolicy.location,
    dataPolicyId: dataPolicy.dataPolicyId,
    role: "roles/viewer",
    members: ["user:jane@example.com"],
});

import pulumi
import pulumi_gcp as gcp

binding = gcp.bigquerydatapolicy.DataPolicyIamBinding("binding",
    project=data_policy["project"],
    location=data_policy["location"],
    data_policy_id=data_policy["dataPolicyId"],
    role="roles/viewer",
    members=["user:jane@example.com"])

package main

import (
	"github.com/pulumi/pulumi-gcp/sdk/v9/go/gcp/bigquerydatapolicy"
	"github.com/pulumi/pulumi/sdk/v3/go/pulumi"
)

func main() {
	pulumi.Run(func(ctx *pulumi.Context) error {
		_, err := bigquerydatapolicy.NewDataPolicyIamBinding(ctx, "binding", &bigquerydatapolicy.DataPolicyIamBindingArgs{
			Project:      pulumi.Any(dataPolicy.Project),
			Location:     pulumi.Any(dataPolicy.Location),
			DataPolicyId: pulumi.Any(dataPolicy.DataPolicyId),
			Role:         pulumi.String("roles/viewer"),
			Members: pulumi.StringArray{
				pulumi.String("user:jane@example.com"),
			},
		})
		if err != nil {
			return err
		}
		return nil
	})
}

    {
        Project = dataPolicy.Project,
        Location = dataPolicy.Location,
        DataPolicyId = dataPolicy.DataPolicyId,
        Role = "roles/viewer",
        Members = new[]
        {
            "user:jane@example.com",

      role: roles/viewer
      members:
        - user:jane@example.com

The DataPolicyIamBinding resource is authoritative for the specified role: it replaces all members for that role on the data policy. The members array accepts various identity formats including user emails, service accounts, groups, and domains. The dataPolicyId, location, and project properties identify which data policy receives the binding.

Add a single member to a role incrementally

When onboarding individual users, teams add them one at a time without affecting existing members.

import * as pulumi from "@pulumi/pulumi";
import * as gcp from "@pulumi/gcp";

const member = new gcp.bigquerydatapolicy.DataPolicyIamMember("member", {
    project: dataPolicy.project,
    location: dataPolicy.location,
    dataPolicyId: dataPolicy.dataPolicyId,
    role: "roles/viewer",
    member: "user:jane@example.com",
});

import pulumi_gcp as gcp

member = gcp.bigquerydatapolicy.DataPolicyIamMember("member",
    project=data_policy["project"],
    location=data_policy["location"],
    data_policy_id=data_policy["dataPolicyId"],
    role="roles/viewer",
    member="user:jane@example.com")

package main

import (

func main() {

			Project:      pulumi.Any(dataPolicy.Project),
			Location:     pulumi.Any(dataPolicy.Location),
			DataPolicyId: pulumi.Any(dataPolicy.DataPolicyId),
			Role:         pulumi.String("roles/viewer"),
			Member:       pulumi.String("user:jane@example.com"),
		})
		if err != nil {
			return err
		}
		return nil
	})
}

using System.Collections.Generic;

using Gcp = Pulumi.Gcp;

return await Deployment.RunAsync(() => 
{
    var member = new Gcp.BigQueryDataPolicy.DataPolicyIamMember("member", new()
    {
        Project = dataPolicy.Project,
        Location = dataPolicy.Location,
        DataPolicyId = dataPolicy.DataPolicyId,
        Role = "roles/viewer",
        Member = "user:jane@example.com",
    });

});

      role: roles/viewer
      member: user:jane@example.com

The DataPolicyIamMember resource is non-authoritative: it adds a single member to a role without modifying other members who already have that role. Use member (singular) instead of members (array) to specify one identity. This resource can coexist with DataPolicyIamBinding resources as long as they manage different roles.

Beyond these examples

These snippets focus on specific IAM binding features: role-based access control and batch and incremental member management. They’re intentionally minimal rather than full access control configurations.

The examples reference pre-existing infrastructure such as BigQuery data policies (dataPolicyId references) and GCP project and location configuration. They focus on configuring IAM bindings rather than provisioning data policies themselves.

To keep things focused, common IAM patterns are omitted, including:

Conditional IAM bindings (condition property)
Full policy replacement (DataPolicyIamPolicy resource)
Custom role definitions
Federated identity configuration

These omissions are intentional: the goal is to illustrate how IAM bindings are wired, not provide drop-in access control modules. See the DataPolicyIamBinding resource reference for all available configuration options.

Frequently Asked Questions

Resource Selection & Conflicts

What's the difference between DataPolicyIamPolicy, DataPolicyIamBinding, and DataPolicyIamMember?

DataPolicyIamPolicy is authoritative and replaces the entire IAM policy. DataPolicyIamBinding is authoritative for a specific role, preserving other roles. DataPolicyIamMember is non-authoritative, adding a single member to a role while preserving other members.

Can I use DataPolicyIamPolicy together with DataPolicyIamBinding or DataPolicyIamMember?

No, DataPolicyIamPolicy cannot be used with DataPolicyIamBinding or DataPolicyIamMember because they will conflict over the policy configuration.

Can I use DataPolicyIamBinding and DataPolicyIamMember together?

Yes, but only if they don’t grant privileges to the same role. Using both for the same role will cause conflicts.

IAM Configuration

How do I grant access to multiple users for the same role?

Use DataPolicyIamBinding with the members array containing multiple identities, such as members: ["user:jane@example.com", "user:john@example.com"].

What member identity formats are supported?

Supported formats include allUsers, allAuthenticatedUsers, user:{emailid}, serviceAccount:{emailid}, group:{emailid}, domain:{domain}, projectOwner:projectid, projectEditor:projectid, projectViewer:projectid, and federated identities like principal://iam.googleapis.com/....

How do I specify custom roles?

Custom roles must use the format [projects|organizations]/{parent-name}/roles/{role-name}, such as projects/my-project/roles/my-custom-role.
